ADJOURNMENT Parks & Recreation Committee Meeting Minutes 06-03-09 PARKS AND RECREATION COMMITTEE MEETING MINUTES Wednesday, June 3,2009 - 6:30 p.m. Pursuant to due call and notice thereof, the Parks & Recreation Committee of the City of Centerville held the regularly scheduled meeting Wednesday, June 3, 2009 at City Hall, 1880 Main Street. Present: Chairperson Suzanne Seeley Vice-Chairperson Kevin Amundsen Committee Member Kevin Selander Committee Member Patrick Branch Committee Member Brian Peterson M[ji)@[P)[~)[f@W~ Absent: Committee Member Mark Haiden Committee Member Savannah Lee Council: City Council Liaison Tom Lee Staff: Staff Liaison Kim Stephan I. CALL TO ORDER 1. Ron Can Vice-Chairperson Amundsen called the June 3, 2009 Parks & Recreation Committee Meeting to order at 6:34 p.m. II. SET AGENDA Vice-Chairperson Amundsen requested adding Dr. Randal Barnes under Appearances, swearing in of new Committee Member Brian Peterson and a discussion of the climbing wall installation at Tracie McBride Memorial Park both under Committee Business. Council Member Lee requested adding the resignation of Committee Member Savannah Lee, also under Committee Business. Motion was made by Chairperson Seeley, seconded by Committee Member Branch, to set the agenda with the above additions. AU in favor. Motion carried unanimously. III. APPEARANCES Dr. Randal J. Barnes, Department of Civil Engineering, University of Minnesota - Discussion regarding the low water flow at Hidden Spring Park. Committee Member Branch invited Dr. Randal Barnes, Department of Civil Engineering, University of Minnesota, to attend the Committee Meeting as a Hugo resident with expertise in natural Iof7 Parks & Recreation Committee Meeting Minutes 06-03-09 hydraulics, to potentially give the committee some insight on what could be done to increase the water flow from the spring at Hidden Spring Park. Also in attendance was Mr. Nathan Barnes. Dr. Barnes first corresponded in an email with some background information and questions for the committee: I am currently involved in studying the long-term trends for groundwater in the greater metropolitan area. Centerville's Hidden Spring Park is an interesting, and potentially enlightening, specific example. In anticipation of the meeting this Wednesday, we have done a bit of background research We were unable to find any records of past flow in the spring, although we have a fairly good sense of the groundwater regime in the area. Any pictures, stories, and anecdotes would be useful. We need to try and get a sense of how often the spring flowed in the past. Some specific questions include: 1. When was the last time the springflowedfreely? 2. How much water was produced? 3. What is the history of the spring? For example, does it (did it) flow every spring, but dry up in the summer or fall? 4. Does anyone have a record of the flow (e.g. regular diary entries)? Photos of the flow could be useful. 5. Were there years in the past when it did not flow at all? 6. Are there any long-time Centerville residents who are familiar with the spring and the properties in the vicinity (up-slope) on the committee? Dr. Barnes and the committee discussed as much history as was available on the spring. Vice- Chairperson Amundsen reported that there are springs in the area, on both Centerville Lake and Peltier Lake, that flow freely all year long. Dr. Barnes is interested in this project because in his position on the faculty at the U of Minnesota, he is already doing research on springs in the area Dr. Barnes spent some time educating the committee on the geology in this part of Minnesota comparing it to a layer cake slightly tilting towards the Mississippi River. All drinking water in Hugo/Centerville is pulled from the Prairie du Chien - Jordan Aquifer(s) which covers a large area. As the aquifers tilt towards the convergence of the three rivers near St. Paul, the wells have to be deeper. Typically with this much development you do not draw drinking water out of the glacial tilt, it has to be taken from deeper in the aquifer. Some lakes in the area are spring fed, like Centerville Lake. White Bear Lake gets most of its water directly from the aquifer as it is actually a fairly deep lake at about 90 feet in some places which comes in direct contact with the aquifer. Centerville Lake is shallow at about 20 feet, but quite a bit of its water is from the Prairie du Chien - Jordan Aquifers also. The aquifers are extremely low, look at White Bear Lake for instance, which is lower than it has been in years. This is perhaps one reason why the spring at Hidden Spring Park has such a low flow. The committee then discussed rainfall as a factor, and while we are in a dry period, it is not driest ever; rain is a factor, but not the significant cause. Dr. Barnes said the DNR has consistently monitored Peltier Lake with the exception of a gap from 2000 to 2004 when the lake was not monitored, and there is valuable information recorded that goes back many years. Anoka County also has a well index requiring every well drilled to be register with the state. The driller, by law, has to supply a report on each well. Vice-Chairperson Amundsen's contention has been that there is 20f7 Parks & Recreation Committee Meeting Minutes 06-Q3-ll9 a constriction holding the spring back as he knows of at least two other springs which flow freely all year, one on Peltier Lake and one just a few houses down from Hidden Spring Park. Dr. Barnes stated there are things we can do to help replenish the aquifers. Water cannot be injected into the aquifer, but an increased recharge can happen by capturing water and sending it into the aquifers through things like rain gardens. Met Council is looking into a variety of things, but it is a very slow process. The lag time between rain and rising of lake levels for instance rain has to go through 100 feet to get to the aqnifers. Dr. Barnes suggested the committee do more research on trends in the area, investigate for instance the other actively flowing springs on Centerville and Peltier Lakes. Vice-Chairperson Amundsen will talk to the neighbor on Centerville Lake and look at the spring on Peltier Lake for comparison. The committee thanked Dr. Barnes for his valuable input. IV. CONSIDERATION OF MINUTES Mav 6. 2009 Parks & Recreation Committee Meetinl!: Minutes Vice-Chairperson Amundsen requested changing the following sentence from will mark to marked on page 4 of 5 under Park Signage. Vice-Chairperson Amundsen will mark on an aerial of Hidden Spring Park where the signs should be placed. Chairperson Amundsen also requested changing the sentence also on page 4 of 5 under Music in the Park that said Jill & the Jacks are available the 1h and the 14th of July to Jill & the Jacks are available the 7tb of July. The 14th is still available. Committee Member Branch requested changing the sentence on page 3 of 5 under 8K Run from Festival Foods has agreed to donate all the bottled water to half ofthe bottled water. Motion was made by Committee Member Branch, seconded by Committee Member Selander, to approve the May 6, 2009 Parks & Recreation Committee Meeting Minutes with the above corrections. All in favor. Motion carried unanimously. V. COMMlTIEE BUSINESS Swearinl!: in of New Committee Member Brian Peterson Chairperson Seeley administered the Oath of Office to Committee Member Brian Peterson and welcomed him to the committee. Increasinl!: Water Flow in the Hidden SDrinl!: I Hidden SDrinl!: Park This item was discussed under appearances. Irril!:ation at Hidden SDrinl! Park The committee discussed the necessity of getting water to the plants at Hidden Spring Park. 30f7 Parks & Recreation Committee Meeting Minutes 06-03-09 Currently the seasonal help is hauling water in the back of a truck and on occasion connecting a hose to the drinking fountain with a sprinkler and then moving it throughout the day, but watering restrictions are in effect and watering can only be done on odd/even days, before 10 a.m. and after 6, which only leaves from 7:30 to 10:00 a.m. on alternate days. Motion was made by Vice-Chairperson Amundsen, seconded by Chairperson Seeley to recommend City Council direct staff to research and get an estirnate(s) to install irrigation at Hidden Spring Park. All in favor. Motion carried unanimously. Hidden Sorin!!: Park PlanOnes Mr. Jeff McDowell, Bonestroo Landscape Architect was at Hidden Spring Park on Tuesday, May 26, 2009 to determine which plants needed to be replaced as a warranty issue. Ms. Stephan met with Mr. McDowell to discuss the plantings on the lakeshore in particular and concerns regarding the lakeshore restoration plantings. Ms. Stephan's concerns are there are so many weeds, mostly thistle and dandelions, on the lakeshore that if these are pulled there will be very little to sustain the soil on the lakeshore. There are some plantings which are believed to be weeds, but neither Ms. Stephan nor Mr. McDowell was sure that they weren't natives planted as lakeshore restoration. Mr. McDowell took pictures which he brought back to the office to try and identify. He reported via email, 'As far as the shoreline goes, I talked to three of our native plant guys. The picture is so poor that none of them could confidently identifY it. However, they all agreed it was not a native, and was probably a weed. But as we discussed on site, be carefUl about removing plants. I don't know how warranty and maintenance is being handled with the installer.' He also determined 44 plants in the raingarden need to be replanted as they did not survive the winter. This is a separate issue from the lakeshore plantings. Bonestroo is only responsible for the warranty on the raingarden plantings. Mr. Larson and Ms. Stephan talked to a representative of Natural Shore Technologies; the company which did the restoration, to inquire as to what was planted and were the plants under warranty. There was some confusion over the invoice and whether the plantings were actually done. Natural Shore Technologies sent pictures via ernail to confirm they planted the shoreline and stated 1,100 plants were installed for a cost of approximately $3,000. There was a maintenance agreement for $900 which would have given a warranty for the plantings. For whatever reason this appeared to be lost in between Bonestroo, the City, Public Works, Parks & Recreation Committee and Natural Shore Technologies because the committee, Ms. Stephan, and Public Works did not know these plants were insta1led and needed to be watered. The plantings were not cared for last fall. The maintenance agreement was never agreed to, we didn't even know it existed until this research was done and the conversation was had by Natural Shore Technologies. It is unknown at this time how many plants survived. The committee would like Mr. Larson have Mr. Statz, Bonestroo, explain how the failure to warranty came about, how could 1,100 plants at a cost of $3,000 not be under a warranty? The last reference in the Parks & Recreation Committee Minutes was in September 2008 when the committee asked when the plants were going to be installed. Apparently they were installed the end of August and were never watered by staff as we did not know they were there and needed to be watered. Ms. Stephan is meeting with a representative of Natural Shore Technologies on June 23, 2009 to discuss options and identify what was actually planted and what are weeds and will report 40f7 Parks & Recreation Committee Meeting Minutes 06-03-09 back to the committee. Climbinl!: Wall Installation at Tracie McBride Memorial Park The climbing wall for Tracie McBride Memorial Park that was donated by Dead Broke Saddle Club was delivered last fall and stored at Public Works for the winter. Mr. Tedd Peterson, Public Works has some questions as to the placement and would like to meet with a member(s) of the committee at the park to discuss this. Chairperson Seeley will contact previous Committee Member Lori Harris, who was involved in the project, and contact Mr. Peterson as to a meeting time. Resil!:Dation of Committee Member Savannah Lee With regret the committee accepts Committee Member Savannah Lee's resignation from the committee. Chairperson Seeley stated Committee Member Lee's opinion was respected as a valuable member of the committee and wished to thank her for her contributions. VI. UPDATES Fete des Lacs 8K Run An update from Captain Ron Nelson of the Centennial Police Department via email concerning the run: Anoka County Highway department will need to be made aware that we intend to cross Centerville Road, which is a county road This will require stopping traffic for a period of time; therefore the highway department needs to be involved. Anoka County Parks also need to be involved as the run will be within their jurisdiction. It appears you have already made arrangements with them. As far as Lino Lakes is concerned, the run travels through their jurisdiction, particularly while in the park. They respond to all calls in the park. Therefore they need to be notified of the event. They may have requirements that need to be met including their own staffing. Sergeant Blanc is in charge of this event and is the one meeting with Pat Branch. He will also be coordinating the other issues. We believe this event will be held, we just need to get all the players involved and on board After everyone has been contacted, we understand each others' role and needs; we will do our best to make the event happen in the safest manner possible. The route may stay the same, or it may have to change. That is yet to be determined An update on Paradel8K Run from Council Member Lee via email: I have the route information for the run and the parade. I am hoping to coordinate our Policing needs with Committee Member Branch and Sergeant Blanc next week. I will be submitting the road 50f7 Parl<s & Recreation Committee Meeting Minutes 06~3-09 permit request to the county early next week and coordinate that effort with Mr. Larson and Ms. Terri Kline at the county. I also have letters ready to submit to notifY Anoka County Dispatch, North Ambulance, Centennial Lakes Fire Department as well as the Centennial Lakes Police Department. I delayed the permit application because of the work being done on CSAH 14. As far as the road crossing for the run, we will need to detour traffic for the parade anyway, so I don't think it will be an issue, we'll just need police presence for trqffic enforcement. We will have MANY volunteers along the route, watching for any health issues. We'll have 4x4 ATVs stationed through out the course as well. Our volunteers will have radio communicationfor both events, to coordinate barricade placement and removal as well as apprise every one of any unplanned issues. Committee Member Branch has contacted all of the sponsors and asked for logos the way they want to see them on the T -ShirtslFlier for the event. Committee Member Branch and Sergeant Blanc rode the course by bicycle and noted any areas of concern that will have to be dealt with such as traffic crossings. Sergeant Blanc would like another water stop added in the Anoka County Park. Closing the entrance to the park for approximately 20 minutes was discussed and Committee Member Branch will discuss this with the County. Barricades were discussed. Council Member Lee stated that these are ordered for the parade and can be moved for the run. The shirt design, flier design, sponsor donations and volunteers were also discussed, as well as the need to get the word out about the run so people will get registered. Chairperson Seeley is going to check with the AnOka County Parks Staff to see if race fliers can be hung on the board at the County Park. Ms. Stephan reported that we do have approval from AnOka County, but nothing in writing yet. The application and fee have been sent in. Emergency vehicles will be able to get in to the trail system; the gates will just need to be opened and Public Works has the ability to open these. Tree I Buckthorn I Poison Ivv Removal at Eade Park Ms. Stephan reported she was in the process of trying to obtain more information as to how other cities handle poison ivy and buckthorn and would report back to the committee. To have it treated by an outside company is an expensive option. Music in the Park The following have been scheduled and confIrmed. Ms. Stephan will make up a flier and get it sent out to the businesses and on the web site. 7 CATS SWING - Tuesday the 7th of July at 7:00 p.m. at Laurie LaMotte Memorial Park.

VII. ADJOURNMENT Motion was made by Committee member Branch, seconded by Chairperson Seeley to adjourn the June 3, 2009 Parks & Recreation Committee Meeting at 8:55 p.m. All in favor. Motion passed unanimously. Trartscribed by Kim Stephan 70f7 MEMO TO: Parks and Recreation Committee Members FROM: Kim Stephan SUBJECT: Updates DATE: June 25, 2009 Irril!:ation at Hidden SDrinl!: Park The Public Works Director has had an irrigation company out to look at Hidden Spring Park and is waiting for the estimate. Hidden SDrinl!: Park Plantinl!:S As of June 25, the 44 replacement plantings have not been planted. Most of these are located in the rain garden. Following the June 3, 2009 Parks & Recreation Committee Meeting, Mr. Jeff McDowell, Bonestroo was informed the committee approved the planting selection that he would like to replace the plants that did not survive with. Mr. McDowell said the plants would be ordered and planted within a few weeks. As of June 23, Mr. McDowell reported he was waiting for an estimate from a landscaper and asked the preference to plant before or after the long Fourth of July weekend. I suggested planting on a Monday or close to the beginning of week would be more beneficial to insure they can be watered by City Staff. No further update at this time. Buckthorn I Poison Ivv Removal at Eal!:le Park I Emerald Ash Borer Attached is a memo to Mr. Larson and Mr. Palzer from myself regarding research I had done on removing the poison ivy and buckthorn in Eagle Park, as well as quotes from TruGreen to treat the poison ivy. Ultimately what the Public Works Director decided to do, partially because of budget cuts, is not treat the poison ivy at all at this time per reconunendation of Mr. Bruce Bousu, Safety Trainer, who said other Cities just mow it. The company the City uses to mow the parks has mowed the area surrounding the park and the trail and it was felt the poison ivy growing in the wooded area of the park should be left as is as. TruGreen is willing to come to a Council Meeting or Parks & Recreation and discuss Emerald Ash Borer and the options available. Mr. Larson asked Public Works for a rough idea of how many Ash trees are in our parks, but Staff did not feel qualified. Mr. Tedd Peterson did meet with a representative from the Minnesota Department of Agriculture on June 25th who installed Ash Borer traps in a few of the Ash trees behind City Hall to determine if the Emerald Ash Borer has made it to Centerville yet. They will be back in August to check the traps. The boxes are purple if you are interested in looking at them. Buckthorn removal will be reviewed again in the fall. - ~ ~ ~ lll:: 00 1.&1 ~ .j ex: '" ~ ..I ~ 0 1.&1 '" = In I: ..... = :E .i In c ; ....IZ - 'Cll = <:E ~ ex: ; ...I ~ -2' a:ai ~ ~ I-Cli:: 0= III 0 otl ~.t , ~ v '" = :iE ~ 1.&1 ;. .. .....z .. lll:: - ~ ~ w! = =0 !i!ex: ~ = ~~ :iE ~ ~ >- sf ... ~ V')Cli:: WU ex:!( tblll ~ Z ... ~!!

PHONE NUMBER Me EXPIRATION DATE CARD HOLDERS SIGNATURE Make Checks Pa able to the C' of Centerville I know that running a road race is a potentially hazardoUll activity and that I should not enter and run unless I am medically able and properly trained. I agree to abide by any decision of a race official relative to my ability to safely complete the run. I assume all risk associate with running in this event including, but not limited to: falls, contact with other participants, the effects of weather, including high heat andlor humidity, traffic and the conditions of the road, all such risk being known and appreciated by me. Having read this waiver and knowing these facts and in consideration of your accepting my enter, I, for myself and anyone entitled to act on my behalf, waive and release the organizers of the Festival of the Lakes 81C, City ofCenterville, USATF, and all sponsors from all claims or liabilities of any kind arising out of my participation in this event or carelessness on the part of the persons named in this waiver. Further, I grant permission to all of the foregoing to use any photographs, motion pictures, recording, or other record of this event for legitimate purposes. SIGNATURE (parent or guardian ifunder 18) DATE Ms Sivarajah~ Thank you for accepting our invitation to be the official Festival of the Lakes 8K starter. This is a first time event for all of us - so we will be learning as we go forward. That being the case, we are open for any suggestions. We will have a portable loud speaker system set up at the race start line on Meadow Lane about 100 yards east of Centerville RD. Once the race is started, we will rapidly move the speaker system to the finish line near the hockey rink in LaMotte Park (about a block away.) I have not discussed final plans with Mayor Capra or Councilman Lee. As our city elected officials who have made this happen, they may elect to welcome the runners and walkers to Centerville. But as a minimum we will follow this sequence. There are announcements I will need to make regarding the course and traffic closures. Also, I want to thank our sponsors and ensure all the runners know who they are. If the Mayor wants to say a few words, I will introduce her and in turn she will introduce you. You then will have an opportunity to say a few words to the participants. Your remarks need to be short - but opportunities like this are a good way for the citizens to meet their elected officials in a non-political environment. For the start we will have an air-powered horn. We will use the old "Runners to your marks - Runners Ready - GO (Horn blast). It may sound a bit silly but it gives everyone due notice including our timer. We well then move to the finish line and set up. I expect the fastest runners to do this 5 mile course in about 25 minutes. You are welcome to participate in announcing the fastest runners, in the awards program (about 9:30 or 10:00) and I understand that you are already in the parade. Facts you may want to use: I will have a card or notes on this on race day: 1. This is the first of what we hope will be a continuing series of annual runs or walks. They will always be associated with Fete des Lacs celebration 2. I will compile the race demographics. Oldest, youngest, total number of men and women etc. 3. Our goals are: a. to create another Fete des Lac community event that draws us together as a community b. to introduce new users and to welcome consistent users of our beautiful parks and trails c. to provide a promotion opportunity to the businesses in the Centerville Economic Development Authority (EDA) 4. Any proceeds that may be generated will go to improve Centerville Parks and Trails. Our Sponsors are paying most of the expenses. The City Council did give us a budget to work with, which I hope to pay back after the event is over. Our sponsors are: 1 Fairview Health Services - providing all the race t-shirts 2. Creative Kids Academy - providing registration assistance 3. The Blue Heron Grill - Awards 4. Festival Foods - Water 5. Liquor Barrel _ Water 6. Michael Giovinazzo, American Family Insurance Agent - water bottles 7. Paul Steffel, Farmers Insurance Agent - water bottles I hope this helps. We can get together either by phone or I would be happy to come to your office and show you the route map, our safety plan, etc. Thanks Again Patrick Branch (703-501-6815 cell) Centerville Park and Recreation Committee Festival of the Lakes 8K, Race Director -----Original Message----- From: Rhonda Sivarajah [mailto:Rhonda.Sivarajah@co.anoka.mn.us] Sent: Saturday, June 27, 2009 8:38 PM To: pbranch@cox.net Cc: mcapra@centervillemn.com Subject: Re: Fete des Lacs Dear Patrick, Thank you for your letter regarding the Fete Des Lacs first annual 8K Run/Walk. I would be honored to serve as the official race starter for the event. Please email me the details and my responsibilities for the morning. I look forward to helping kick off the event. Sincerely, Rhonda Sivarajah Anoka County Commissioner Attached to this email is Albrecht's proposal for installing an underground irrigation system at the park site off LaMotte Dr. in Centerville, MN. The system includes a 15 station controller running 63 rotors (14 valves) spaced between 30-33' apart. The additional valve would run as part of the water feature on site. Our hookup is located right next to the drinking fountain near the Gazebo and would utilize the 1" service line providing water to the fountain. our power from the controller would be 110v service line from the "hand-hole" next to the Gazebo provided by Albrechts. The vacuum breaker and controller would be housed in a lockable enclosure with rough dimensions of 36"Hx24"WxlS"L near the drinking fountain. I designed the system to fit within an S hour watering period with matched precipitation and uniform distribution of water throughout the site. I also tried to match individual "mireo-climates" with zone location to help with maximum control (ex. avoiding zoning together areas of full-sun and fUll-shade). I have a schematic design put together and would like a chance to sit down with you to further explain my reasoning behind the design.

"The first is a water-blilaring strata ot sand and, gravel, which Wall "struck at a depth from the surfacs of from fitty to eeventy-six feet, and "Wall from fifteen to twenty-two relit in dllPth. "The second water vein is in tbe sand rock, anqwas struck at a depth 10 "of about 350 feet, the wells varying in depth from 302 to 523 feet.

This beetle was first discovered in 2002 in southeast Michigan and Windsor, Ontario. As of June 2009, emerald ash borer (EAS) infes- tations were known to be present in 12 states and two Canadian provinces. Many hom- eowners, arborists and tree care profession- als want to protect valuable ash trees from EAB. Scientists have learned much about this insect and methods to protect ash trees since 2002. This bulletin is designed to answer frequently asked questions and provide the most current information on insecticide options for controlling EAB. Answers to Frequently Asked Questions ,i) If you elect to treat your ash trees, there are several insecticide options available and research has shown that treatments can be effective. Keep in mind, however, that con- trolling insects that feed under the bark with insecticides has always been difficult. This is especially true with EAB because our native North American ash trees have little natural resistance to this pest. In university trials, some insecticide treatments were effective in Herms. McCullough, Smitley. Sadof. Williamson, Nixon some sites, but the same treat- ments failed in other sites. Further- more, in some studies conducted over multiple years, EAB densities continued to increase in individual trees despite annual treatment. Some arborists have combined treatments to increase the odds of success (e.g., combining a cover spray with a systemic treatment). Our understanding of how EAB can be managed successfully with insecticides has increased substantially in recent years. The current state of this understanding is detailed in the bulletin. It is important to note that research on management of EAB remains a work in progress. Scientists from universities, government agencies and com- panies continue to conduct intensive studies to understand how and when insecticide treatments will be most effective. . ", :)'./ :;'\\' 0' 1e:: ,! :'h ,[;:/'-\:-? h., "if(:ct,\/l; :l';;'::C:!''':i'::C - If a tree has lost more than 50 percent of its canopy, it is probably too late to save the tree. Studies have shown that it is best to begin using insecticides while ash trees are still relatively healthy. This is because most of the insecticides used for EAB control act systemically - the insecticide must be trans- ported within the tree. In other words, a tree must be healthy enough to carry a systemic , insecticide up the trunk and into the branches and canopy. When EAB larvae feed, their gai- leries injure the phloem and xylem that make up the plant's circulatory system. This inter- feres with the ability of the tree to transport nutrients and water, as well as insecticides. As a tree becomes more and more infested, the injury becomes more severe. Large branches or even the trunk can be girdled by the larval galleries. Studies have also shown that if the canopy of a tree is already declining when insecticide treatments are initiated, the condition of the tree may continue to deteriorate during the first year of treatment. In many cases, the tree canopy will begin to improve in the second year of treatment. This lag in the reversal of canopy decline probably reflects the time needed for the tree to repair its vascular system after the EAB infestation has been reduced. Scientists have learned that ash trees with low densities of EAB often have few or no exter- nal symptoms of infestation. Therefore, if your property is within a county that has been quarantined for EAB, your ash trees are prob- ably at risk. Similarly, if your trees are outside a quarantined county but are still within 10-15 miles of a known EAB infestation, they may be at risk. If your ash trees are more than 15 miles beyond this range, it is probably too early to begin insecticide treatments. Treatment programs that begin too early are a waste of money. Remember, however, that new EAB infestations have been discov- ered every year since 2002 and existing EAB populations will build and spread over time. Stay up to date with current EAB quaran- tine maps and related information at www. emeraldashborer.info. You can use the links in this Web site to access specific information for individual states. When an EAB infesta- tion is detected in a state or county for the first time, it will be added to these maps. Note, however, that once an area has been quarantined, EAB surveys generally stop, and further spread of EAB in that area will not be reflected on future maps. -' 1 realllH lhat i \/\'ill ha.,/e to protect my ash tn:f:.g froilI EAB for sevPfi::d ye;FS. L:; it worth it? The economics of treating ash trees with insecticides for EAB protection are com- plicated. Factors that can be considered include the cost of the insecticide and expense of application, the size of the trees, the likelihood of success, and potential costs of removing and replacing the trees. Until recently, insecticide products had to be applied every year. A new product that is effective for two years or even longer (emamectin benzoate) has altered the eco- nomics of treating ash trees. As research pro- gresses, costs and methods of treating trees will continue to change and it will be impor- tant to stay up to date on treatment options. Benefits of treating trees can be more difficult to quantify than costs. Landscape trees typi- cally increase property values, provide shade and cooling, and contribute to the quality of life in a neighborhood. Many people are sen- timental about their trees. These intangible qualities are important and should be part of any decision to invest in an EAB management program. It is also worth noting that the size of EAB populations in a specific area will change over time. Populations initially build very slowly, but later increase rapidly as more trees become infested. As EAB populations reach their peak, many trees will decline and die within one or two years. As untreated ash trees in the area succumb, however, the local EAB population will decrease substantially. Scientists do not yet have enough experi- ence with EAB to know what will happen over time to trees that survive the initial wave of EAB. Ash seedlings and saplings are common in forests, woodlots, and right-of- ways, however, and it is unlikely that EAB will ever completely disappear from an area. That means that ash trees may always be at some risk of being attacked by EAB, but it seems reasonable to expect that treatment costs could eventually decrease as pest pressure declines after the EAB wave has passed. INSECTICIDE OPTIONS FOR PROTECTING ASH TREES FROM EMERALD ASH BORER Insecticide Options for Controlling EAB Insecticides that can effectively control EAB fall into four categories: (1) systemic insec- ticides that are applied as soil injections or drenches; (2) systemic insecticides applied as trunk injections; (3) systemic insecticides applied as lower trunk sprays; and (4) pro- tective cover sprays that are applied to the trunk, main branches, and (depending on the label) foliage. Insecticide formulations and application methods that have been evaluated for control of EAB are listed in Table 1. Some are mar- keted for use by homeowners while others are intended for use only by professional applicators. The "active ingredient" refers to the compound in the product that is actually toxic to the insect. Formulations included in Table 1 have been evaluated in multiple field trials conducted by the authors. Inclusion of a product in Table 1 does not imply that it is endorsed by the Table 1.

Please see the following sec- tions for specific information about results from these trials. Results of some tests have also been posted on www.emeraldashborer. info. Strategies for the most effective use of these insecticide products are described below. It is important to note that pesticide labels and registrations change constantly and vary from state to state. It is the legal responsibility of the pesticide applicator to read, understand and follow all current label directions for the specific pesticide product being used. Using Insecticides to Control EAB h:.(j i;l':~;:-:C,- '~::d~'s Systemic insecticides applied to the soil are taken up by the roots and translocated throughout the tree. The most widely tested soil-applied systemic insecticide for control of EAB is imidacloprid, which is available under several brand names for use by professional applicators and homeowners (see Table 1). All imidacloprid formulations can be applied as a drench by mixing the product with water, then pouring the solution directly on the soil around the base of the trunk. Dinotefuran was recently labeled for use against EAB as a soil treatment (in addition to its use as a basal trunk spray discussed beiow). Studies to test its effectiveness as a soil treatment are cur- rently underway in Michigan and Ohio. Imidacloprid soil applications should be made when the soil is moist but not satu- rated. Application to water-logged soil can result in poor uptake if the insecticide becomes excessively diluted and can aiso result in puddles of insecticide that could wash away, potentially contaminating surface waters and storm sewers. Insecticide uptake will also be limited when soil is excessively dry. Irrigating the soil surrounding the base of the tree before the insecticide application can improve uptake. The application rates for the homeowner product (Bayer Advanced'" Tree & Shrub Insect Control) and professional formulations -' of imidacloprid are very similar. Homeowners apply the same amount of active ingredient that professionals apply. However, there are certain restrictions on the use of homeowner formulations that do not apply to professional formulations. Homeowner formulations of imidacloprid can be applied only as a drench. It is not legal to inject these products into the soil, although some companies have mar- keted devices to homeowners specifically for this purpose. Homeowners are also restricted to making only one application per year. Several generic products containing imida- c10prid are available to homeowners, but the formulations vary and the effectiveness of these products has not yet been evaluated in university tests. Soil drenches offer the advantage of requir- ing no special equipment for applica- tion other than a bucket or watering can. However, imidacloprid can bind to surface layers of organic matter, such as mulch or leaf litter, which can reduce uptake by the tree. Before applying soil drenches, it is impor- tant to remove, rake or pull away any mulch or dead leaves so the insecticide solution is poured directly on the mineral soil. Imidacloprid formulations labeled for use by professionals can be applied as a soil drench or as soil injections. Soil injections require specialized equipment, but offer the advan- tage of placing the insecticide under mulch or turf and directly into the root zone. This also can help to prevent runoff on sloped surfaces. Injections should be made just deep enough to place the insecticide beneath the soil surface (2-4 inches). Soil injections should be made within 18 inches of the trunk where the density of fine roots is highest. As you move away from the tree, large radial roots diverge like spokes on a wheel and studies have shown that uptake is higher when the product is applied at the base of the trunk. There are no studies that show that applying fertilizer with imidacloprid enhances uptake or effectiveness of the insecticide. Optimal timing for imidacloprid soil injec- tions and drenches is mid-April to mid-May, depending on your region. Allow four to six weeks for uptake and distribution of the insecticide within the tree. In southern Ohio, for example, you would apply the product by INSECTICIDE OPTIONS FOR PROTECTING ASH TREES FROM EMERALD ASH BORER mid-April; in southern Michigan, you should apply the product by early to mid-May. When treating larger trees (e.g., with trunks larger than 12 inches in diameter), treat on the earlier side of the recommended timing. Large trees will require more time for uptake and transportation of the insecticide than will small trees. Recent tests show that imidaclo- prid soil treatments can also be successful when applied in the fall. Trunk-!njected Systemic insecticides Several systemic insecticide products can be injected directly into the trunk of the tree including formulations of imidacloprid and emamectin benzoate (see Table 1). An advantage of trunk injections is that they can be used on sites where soi I treatments may not be practical or effective, including trees growing on excessively wet, compacted or restricted soil environments. However, trunk injections do wound the trunk, which may cause long-term damage, especially if treat- ments are applied annually. Products applied as trunk injections are typically absorbed and transported within the tree more quickly than soil applications. Allow three to four weeks for most trunk- injected products to move through the tree. Optimal timing of trunk injections occurs after trees have leafed out in spring but before EAB eggs have hatched, or generally between mid-May and mid-June. Uptake of trunk-injected insecticides will be most effi- cient when trees are actively transpiring. Best results are usually obtained by injecting trees in the morning when soil is moist but not saturated. Uptake will be slowed by hot after- noon temperatures and dry soil conditions. Dinotefuran is labeled for application as a noninvasive, systemic bark spray for EAB control. It belongs to the same chemical class as imidacloprid (neonicotinoids) but is much more soluble. The formulated insecticide is sprayed on the lower five to six feet of the trunk using a common garden sprayer and low pressure. Research has shown that the insecticide penetrates the bark and moves systemically throughout the rest of the tree. Herms. McCullough, Smitley. Sadoff Williamson. Nixon Dinotefuran can be mixed with surfactants that may facilitate its movement into the tree, particularly on large trees with thick bark. However, in field trials, adding a surfactant did not consistently increase the amount of insecticide recovered from the leaves of treated trees. The basal trunk spray offers the advantage of being quick and easy to apply and requires no special equipment other than a garden sprayer. This application technique does not wound the tree, and when applied correctly, the insecticide does not enter the soil. Healthy ash trees that have been protected with insecticides growing next to untreated ash trees killed by EAB. :"),.,-.';' Insecticides can be sprayed on the trunk, branches and (depending on the label) foliage to kill adult EAB beetles as they feed on ash leaves, and newly hatched larvae as they chew through the bark. Thorough cover- age is essential for best results. Products that have been evaluated as cover sprays for control of EAB include some specific formula- tions of permethrin, bifenthrin, cyfIuthrin and carbaryl (see Table 1). Protective cover sprays are designed to prevent EAB from entering the tree and will have no effect on larvae feeding under the bark. Cover sprays should be timed to occur when most adult beetles are feeding and beginning to lay eggs. Adult activity can be difficult to monitor because there are no -" EAB adults must feed on foliage before they become reproduc. tively mature. ~ effective pheromone traps for EAB. However, first emergence of EAB adults generally occurs between 450-550 degree days (start- ing date of January 1, base temperature of 50'F), which corresponds closely with full bloom of black locust (Robinia pseudoacada). For best results, consider two applications, one at 500 DDso (as black locust approaches full bloom) and a second spray four weeks later. How Effective Are Insecticides for Control of EAB? Extensive testing of insecticides for control of EAB has been conducted by researchers at Michigan State University (MSU) and The Ohio State University (OSU). Results of some of the MSU trials are available at www.emer- aldashborer.info. ;"!'p;e: Efficacy of imidacloprid soil injections for con- trolling EAB has been inconsistent; in some trials EAB control was excellent, while others yielded poor results. Differences in applica- tion protocols and conditions of the trials have varied considerably, making it difficult to reach firm conclusions about sources of variation in efficacy. For example, an MSU study found that low-volume soil injections of imidacloprid applied to small trees averag- ing 4 inches in DBH (diameter of the trunk at breast height) using the Kioritz applicator (a hand-held device for making low-volume injections) provided good control at one site. However, control was poor at another site where the same application protocols were used to treat larger trees (13-inch DBH). Imidacloprid levels may have been too low in the larger trees to provide adequate control. Higher pest pressure at the second site also may have contributed to poor control in the large trees. In the same trials, high-pressure soil injections of imidacloprid (applied in two concentric rings, with one at the base of the tree and the other halfway to the drip line of the canopy) provided excellent control at one site. At another site, however, soil injections applied using the same rate, timing and application method were completely ineffective, even though tree size and infestation pressure were very similar. It should be noted that recent studies have shown that imidacloprid soil injections made at the base of the trunk result in more effective uptake than applica- tions made on grid or circular patterns under the canopy. lmidacloprid soil drenches have also gen- erated mixed results. In some studies conducted by MSU and OSU researchers, imidacloprid soil drenches have provided excellent control of EAB. However, in other studies, control has been inconsistent. Expe- rience and research indicate that imidacloprid soil drenches are most effective on smaller trees and control of EAB on trees with a DBH that exceeds 15 inches is less consistent. This inconsistency may be due to the fact that application rates for systemic insecticides are based on amount of product per inch of trunk diameter or circumference. As the DBH of a tree increases, the amount of vascular tissue, leaf area and biomass that must be protected by the insecticide increases expo- nentially. Consequently, for a particular appli- cation rate, the amount of insecticide applied as a function of tree size is proportionally decreased as trunk diameter increases. Hence, the DBH-based application rates that effectiveiy protect relatively small trees can be too low to effectively protect large trees. Some systemic insecticide products address this issue by increasing the application rate for large trees. In an OSU study with larger trees (15- to 22-inch DBH), Xytect™ (imidacloprid) soil drenches provided consistent control of EAB when applied experimentally at twice the rate that was allowed at that time. Recently, the Xytect™ label was modified to allow the use of this higher rate, which we now recommend when treating trees larger than 15-inch DBH. Merit"' imidacloprid formulations, however, are not labeled for application at this high rate. Therefore, when treating trees greater than 15-inch DBH with Merit"' soil treatments, two applications are recommended, either in the fall and again in the spring, or twice in the spring, about four weeks apart (for example in late April and again in late May). This is not an option for Bayer Advanced™ Tree and Shrub Insect Control and other INSECTICIDE OPTIONS FOR PROTECTING ASH TREES FROM EMERAW ASH BORER homeowner formulations of imidacloprid, which are limited by the label to one applica- tion per year. Homeowners wishing to protect trees larger than 15-inch DBH shouid con- sider having their trees professionally treated. Treatment programs must comply with any limits specified on the label regarding the maximum amount of insecticide that can be applied per acre during a given year. Syst,;,'!"n:c ir'~J(;ct1cid;:",?, Emamectin benzoate. In several inten- sive studies conducted by MSU and OSU researchers, a single injection of emamectin benzoate in mid-Mayor early June pro- vided excellent control of EAB for at least two years, even under high pest pressure. For example, in a highly-replicated study conducted on trees ranging in size from 5- to 20-inch DBH at three sites in Michigan, untreated trees had an average of 68 to 132 EAB larvae per m' of bark surface, which represents high pest pressure. In contrast, trees treated with emamectin benzoate had, on average, only 0.2 larvae per m', a reduc- tion of > 99 percent. When additional trees were felled and debarked two years after the emamectin benzoate injection, there were still virtually no larvae in the treated trees, while adjacent, untreated trees at the same sites had hundreds of larvae. In two OSU studies conducted in Toledo with street trees ranging in size from 15- to 25-inch D8H, a single application of emamectin benzoate also provided excel- lent control for two years. There was no sign of canopy decline in treated trees and very few emergence holes, while the canopies of adjacent, untreated trees exhibited severe decline and extremely high numbers of emer- gence holes. One study suggests that a single injection of emamectin benzoate may even control EAB for three years. Additional studies to further evaluate the long-term effectiveness of emamect;n benzoate are underway. To date, this is the only product that controls EAB for more than one year with a single application. In addition, in side-by-side comparisons with other systemic products (neonicotinoids), emamectin benzoate was more effective. Herms. McCullough, Smitley, Sadof, Williamson, Nixon Imidacloprld . Trunk injections with imidaclo- prid products have provided varying degrees of EAB control in trials conducted at different sites in Ohio and Michigan. In an MSU study, larval density in trees treated with Imicide" injections were reduced by 60 percent to 96 percent, compared to untreated controls. There was no apparent relationship between efficacy and trunk diameter or infestation pressure. In another MSU trial, imidacloprid trunk injections made in late May were more effective than those made in mid-July, and IMA-jet" injections provided higher levels of control than did Imicide", perhaps because the IMA-jet" label calls for a greater amount of active ingredient to be applied on large trees. In an OSU study in Toledo, IMA-jet" provided excellent control of EAB on 1 S- to 25-inch trees under high pest pressure when trees were injected annually. However, trees that were injected every other year were not consistently protected. In a discouraging study conducted in Michi- gan, ash trees continued to decline from one year to the next despite being injected in both years with either Bidrin (Inject-A-Cide B"l or imidacloprid. The imidacloprid treat- ments consisted of two consecutive years of Imicide" (10% imidacloprid) applied using Mauget" micro-injection capsules, or an experimental 12% formulation of imidaclo- prid in the first year followed by PointerTM (5% imidacloprid) in the second year with both applied using the Wedgle™ Direct- Inject™ System. All three treatment regimes suppressed EAB infestation levels in both years, with Imicide" generally providing best control under high pest pressure in both small (six-inch DBH) and larger (16-inch DBHl caliper trees. However, larval density increased in treated and untreated trees from one year to the next. Furthermore, canopy dieback increased by at least 67 percent in all treated trees (although this was substantially less than the amount of dieback observed in untreated trees). Even consecutive years of these treatments only slowed ash decline under severe pest pressure. In another MSU study, ACECAP" trunk implants (active ingre- dient is acephate) did not adequately protect large trees (greater than 15-inch DBH) under high pest pressure. EAB larvae damage the vascular system ofcthe tree as they feed, which interferes with movement of systemic insecticides in the tree. -' -f" ... fill..,;' ,,,":/: '.~~ ~ " .:~ /"..:_ \ . . .""}l~. d, /~'_' ',~,~ ,......

MSU and OSU studies have evaluated residues in leaves from trees treated with the basal trunk spray. Results show that the dinotefuran effectively moved into the trees and was translocated to the canopy at rates similar to those of other trunk-injected insecticides, and faster than other soil-applied neonicotinoid products. As with imidacloprid treatments, control of EAB with dinotefuran has been variable in research trials. In an MSU study conducted in 2007 and 2008, dinotefuran trunk sprays reduced EAB larval density by approxi- mately 30 percent to 60 percent compared to the heavily infested untreated trees. The treatment was effective for only one year and would have to be applied annually. In general, control is better and more consistent in smaller trees than in large trees, but more research is needed with larger trees. Studies to address the long-term effectiveness of annual dinotefuran applications for control of EAB are underway. -' ProtectIve Covet- Sprays MSU studies have shown that applications of OnyxTM, Tempo'" and Sevin'" SL provided good control of EAB, especially when the insecticides were applied in late May and again in early July. Acephate sprays were less effective. BotaniGard'" (Beauvaria bass;ana) was also ineffective under high pest pres- sure. Astro'" (permethrin) was not evaluated against EAB in these tests, but has been effective for controlling other species of wood borers and bark beetles. in another MSU study, spraying Tempo'" just on the foliage and upper branches or spraying the entire tree were more effective than simply spraying just the trunk and large branches. This suggests that some cover sprays may be especially effective for con- trolling EAB adults as they feed on leaves in the canopy. A single, well-timed spray was also found to provide good control of EAB, although two sprays may provide extra assurance given the long period of adult EAB activity. It should be noted that spraying large trees is likely to result in a considerable amount of insecticide drift, even when conditions are ideal. Drift and potential effects of insecti- cides on non-target organisms should be considered when selecting options for EAB control.

INSECTICIDE OPTIONS FOR PROTECTING ASH TREES FROM EMERALD ASH BORER Key Points and Summary Recommendations , Insecticides can effectively protect ash trees from EAB. , Unnecessary insecticide applications waste money. If EAB has not been detected within 10-15 miles, your trees are at low risk. Be aware of the status of EAB in your location. Current maps of known EAB populations can be found at www.emer- aldashborer.info. Remember, however, that once a county is quarantined, maps for that county are no longer updated. , Trees that are already infested and showing signs of canopy decline when treatments are initiated may continue to decline in the first year after treatment, and then begin to show improvement in the second year due to time lag associated with vascular healing. Trees exhibiting more than 50 percent canopy decline are unlikely to recover even if treated. , Emamectin benzoate is the only product tested to date that controls EAB for more than one year with a single application. It also provided a higher level of control than other products in side-by-side studies. , Soil drenches and injections are most effective when made at the base of the trunk. Imidacloprid applications made in the spring or the fall have been shown to be equally effective. , Soil injections should be no more than 2-4 inches deep, to avoid placing the insecticide beneath feeder roots. , To facilitate uptake, systemic trunk and soil insecticides should be applied when the soil is moist but not saturated or excessively dry. , Research and experience suggest that effectiveness of insecti- cides has been less consistent on larger trees. Research has not been conducted on trees larger than 25-inch DBH. When treating very large trees under high pest pressure, it may be necessary to consider combining two treatment strategies. , Xytect™ soil treatments are labeled for application at a higher maximum rate than other imidacloprid formulations, and we recommend that trees larger than 15-inch DBH be treated using the highest labeled rate. Merit" imidacloprid formulations are not labeled for use at this higher rate. When treating larger trees with Merit" soil treatments, best results will be obtained with two applications per year. Imidacloprid formulations for homeowners (Bayer AdvancedTM Tree & Shrub Insect Control and other generic formulations) can be applied only once per year. , Homeowners wishing to protect trees larger than 15-inch DBH should consider having their trees professionally treated. , Treatment programs must comply with any label restrictions on the amount of insecticide that can be applied per acre in a given year.
