Abstract: EnviroScience (ES) biologists have been monitoring the changes to the plant community in areas directly related to the milfoil weevil and its’ impact on EWM since the inception of the program in 2007. However since 2013, ES was requested to capture a more detailed inventory of submersed and emergent aquatic plant community of the shorelines of the Les Cheneaux Chain of Islands (LCI) on Lake Huron. This was initiated after the infestation of EWM increased to approximately 1,000 acres throughout LCI in 2012.

2015 Vegetation and Weevil Population Surveys

Abstract: 2015 was the third year of EnviroScience performing a vegetation survey following the same methods outlined in the Michigan Department of Environmental Quality (MDEQ) and at similar times each summer to ensure consistent plant identification each survey year. The goal of this survey was to document the extent of the aquatic invasive species Eurasian watermilfoil (Myriophyllum spicatum, herein referred to as milfoil), as well as to document the diverse native plant community occurring in the bays and navigation channels throughout the Les Cheneaux Islands.

 2014 Vegetation and Weevil Population Surveys

Abstract: At the request of the Les Cheneaux Watershed Council (LCWC), a vegetation survey was conducted throughout nine bays and channels of the Les Cheneaux Chain of Islands (LCI) from August 11 to 13, 2014 (Table 1.0, Figure 1.0). The purpose of this survey was to compile an inventory of all submersed aquatic vegetation species, identify locations of Eurasian watermilfoil (Myriophyllum spicatum) (EWM) infestation, and identify additional invasive/nuisance species to provide a baseline for future management practices. A milfoil weevil (Euhrychiopsis lecontei) population survey was also conducted in Cedarville, Sheppard’s, and Smith’s Bays to document the extent to which the weevils have controlled the EWM in the project areas per the requirements of the stocking contract.
