Special Guest Speaker Chair Ferrington introduced guest speaker, Mr. Chip Welling, Coordinator for Aquatic Invasive Species Management with the Minnesota Department of Natural Resources (MN DNR), Waters Division to present an overview and lead discussion on aquatic weed management efforts, invasive species in area bodies of water, and available grants and programs. Mr. Welling provided the objectives of the Invasive Species Program in preventing invasions or spread through effective management and the broader mission of the MN DNR; and presented an extensive overview of the DNR Aquatic Invasive Species Control, specifically the locations of and management of Curly -leaf Pondweed and Eurasian Watermilfoil. Topics for the presentation included; Lake Owasso as a "grandfathered lake," a designation allotted to a limited number of lakes in the metropolitan area with a sunset target date for application of vegetative treatments; after which a Lake Vegetation Management Plan would be enacted, aiming for performance of rules similar to other lakes in the State of MN. Mr. Welling noted the invasion of Eurasian Watermilfoil in the State of MN in approximately 1987 and spreading to more than 750 lakes since the early 1900's; increasing funds through the years for resources to manage Curly -leaf Pondweed and Purple Loosestrife; preference for natural bio- control agents for their control; problems caused by non native plants and invasive species in lakes; and pilot projects initiated in 2006 for their elimination and /or management. Mr. Welling noted that additional information on known invasive species was available on the DNR website; and provided his contact information: e-mail: chip.welling@dnr.state.mn.us or phone at 651/259 -5149. Curly -Leaf Pondweed Mr. Welling reviewed pilot projects and goals for management specific to Curly -leaf Pondweed; the number of years that lake -wide treatment had been used and the effectiveness; grant monies available for some, but not all, required treatment costs and requiring a significant local match for larger lakes, with all treatments options being expensive and time consuming. Mr. Welling provided examples of several metropolitan lakes, and results of before and after treatment in terms of water quality and clarity from application of various types of treatments (e.g. Alum, Rotenone) and any increase or reappearance of native plants following treatment.
