Project Summary:

In conducting reconnaissance of 78 EWM-infested lakes in 2004, we became aware of a need for general information on basic EWM ecology. It became apparent that at the statewide level, we lacked even the most basic information (including EWM coverage and species lists of natives) on the state’s approximately 400 EWMinfested lakes. We conducted quantitative baseline surveys on 100 lakes with EWM to evaluate the abundance and distribution of EWM populations as well as link the status of these populations to lake physical factors and past management.
