Project Informationlegacy

Boot Lake is one of MN DNR’s Scientific and Natural Areas (SNA). Boot Lake SNA is part of a chain of ice-block lakes which were formed by sub-glacial rivers. The site contains a diversity of native plant communities including oak forest, aspen-shrub thickets, white pine stands, wooded bogs and wet meadows. Rare and notable flora and fauna make their home in Boot Lake SNA.

Invasive glossy buckthorn (Frangula alnus) has established in the wetland communities, including in areas where the rare waterwillow (Decodon verticillatus var. laevigatus) is present.

The Anoka Conservation District (ACD) began treating glossy buckthorn at Boot Lake SNA with basal bark application of triclopyr herbicide in winter 2016/2017. Treatment occurred in a 26.5 acre wetland with dense glossy buckthorn growing among desirable native shrubs. This treatment will be monitored in spring and summer 2017. Follow-up treatment will take place in the 2017-2018 winter.
