2021 Summary

The Finger Lakes PRISM consulted with CC Environment and Planning to update our 5-year strategic plan. The result is a more succinct plan with measurable goals and outputs. The Finger Lakes PRISM and Finger Lakes Institute at Hobart and William Smith Colleges have been charging through our work plans and objectives. What follows is a small representation of what we’ve accomplished since January 1, 2021. While we have much more to finish before year’s end, we are proud of the work we’ve undertaken to prevent the spread and impact of invasive species in the Finger Lakes.
