Guest Blog: Precision aquatic plant assessment and management in Michigan Lakes

By Jennifer L. Jermalowicz-Jones

Restorative LakeSciences is actively involved in the management and restoration of nearly 60 lakes in the state of Michigan and on water bodies in other states such as California and Wisconsin.  As an innovative specialty firm of advanced-degreed limnology experts, our goal is to provide thorough educational training to lake communities while using the most innovative technologies for lake improvements.  ciBioBase software (Contour Innovations, LLC) in combination with the Lowrance® HDS8 side- and down-scanning capabilities allows us to precisely determine the biovolume of the submersed aquatic vegetation in inland lakes.  Additionally, it also assists in the determination of individual aquatic vegetation bed areas that are mapped by aquatic botanists to be treated precisely with systemic or contact aquatic herbicides or with other removal technologies (Figure 1).  This technology has resulted in highly effective reductions of nuisance aquatic vegetation biovolume and bed densities due to the precision of treatments.  As a result, all of our lake management communities have been satisfied with the strategy and can easily see significant progress within a single season.

Jennifer L. Jermalowicz-Jones, MS, Ph.D Candidate, is the Water Resources Director at Restorative Lake Sciences and oversees over nearly 60 inland lake projects which include aquatic vegetation mapping and management, lake sediment reduction studies and management, algal quantification and identification and algal management programs, and watershed management programs.  She has over 24 years of experience in lake research and management and is pursuing her doctoral degree from Michigan State University in Water Resource Management.  She is also the President of the Michigan Chapter of the North American Lake Management Society, serves as the Science Advisory Chair on the Michigan Lake and Stream Associations Executive Board of Directors, has won numerous awards and grants for her aquatic ecosystem research, and has presented numerous papers at state and national conferences on water resource and lake management.
