LOWER NEMAHBIN LAKE ASSOCIATION: Starry Stonewort Nemahbin Launch 3

The Association is sponsoring a project to control starry stonewort (Nitellopsis obtusa) located by the public launches by the Bark River and Lower Nemahbin south of the I-94 bridge. This project continues work under AIRR27723 and AIRR25420.

Deliverables: 1) NR109 harvesting reports for each removal event describing the DASH removal project, problems encountered, removal location maps, and a summary of amount of starry stonewort (SSW) and non-target plants removed. 2) APM plan, to include: a) summary of relevant survey data since 2006; b) tables comparing FOO and density of species over years; c) table with 2022 data, FOO and density; d) Species density distribution maps for EWM, SSW, and top 5 natives; e) Discuss changes in plant community; f) summarize 2019-2023 hand pulling efforts and analyze efficacy; g) Map showing points SSW found each year; h) Plan for long term management of SSW, including launch areas and new populations outside of launches; i) Options for managing EWM, including chemical or mechanical/manual; j) Clean Boats Clean Waters (CBCW) options (e.g. partnering with Waukesha County or writing an annual grant); k) Long term funding needs.

Activities: 1) Two DASH removal events per summers of 2023 and 2024; 2) Annual harvesting reports; 3) Create APM plan.
