Attachment 5 Parks & Recreation — Emerald Ash Borer (EAB) Program Update — March 2023 353 Trees Currently Removed, this number increases daily with their work Tree removals right now are being stored in the Dale Street Soccer Fields parking lot and will be tub -ground at the end of March 452 is the number of trees that will be planted this year 175 in the spring and 277 in the fall As we talked about on the phone we are getting some questions on why we are using some non -natives, especially Ginko's. Here is the response I have been giving: Ginkgo is one of the selected species because it is grossly under -represented in the City of Roseville's urban tree population. The DNR reports there are less than 200 in our inventory. During a time of recovery from an invasive species directed to one particular genus of trees amplifies the necessity to plant a diversity of species. Diversity can come in a variety of ways: The city of Roseville is taking steps to increase its diversity and create resilience. This includes the planting of non-native, demonstrated non-invasive species such as: Ginkgo, London planetree, Maybe maple and zelkova. These types of trees represent less than 5% of the total trees planted through this program and can mean the difference of a portions of our city having a few trees, to having none at all. This is a best management practice in urban forestry management as we take the much -needed steps to ensure the future residents of our community benefit from the trees we plant today. A good example of why we need to add diverse species is our Maple population. Everybody loves a maple tree but the DNR reports we have 40,000 maple trees which makes up 24% of our total tree population. Overreliance on a small number of traditionally native tree species could put us in the same situation we are now if we are not diverse in our use of pest and disease resistant species. As part of this project we are very fortunate to have some of the best and brightest minds in the urban forestry industry. The decisions we are making are rooted in science and is what's best for our canopy moving forward.
