Summary
Observations and subtle shifts of vegetation communities in Lake Erie have USGS researchers concerned about the potential for Grass Carp to alter these vegetation communities. Broad-scale surveys of vegetation using remote sensing and GIS mapping, coupled with on-the-ground samples in key locations will permit assessment of the effect Grass Carp may have already had on aquatic vegetation communities and establish baseline conditions for assessing future effects. Existing aerial imagery was used with object-based image analysis to detect and map aquatic vegetation in the eastern basin of Lake Erie.

The aquatic vegetation of Lake Erie was mapped to establish baseline conditions for assessing current and future effects Grass Carp may have on the relative abundance and distribution of vegetation communities in Lake Erie. This aquatic vegetation detection map can be used to spatially compare vegetation shifts in detection and coverage over time in future remote sensing and GIS mapping of broad-scale aquatic vegetation surveys.
