 2014 Vegetation and Weevil Population Surveys

Authors: Cortney Marquette; Sarah Walters

Author Affiliation: Enviroscience

Journal: Privately published for LCWC

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.
