|Working to install mats at Glenburnie site.|
At the beginning of the month divers from AIM began fall treatment work at the Glenburnie site. This new site was found during the lakewide survey on September 3. First the divers completed a thorough survey of the site to determine the extent of the infestation. They then installed benthic barriers weighted down with sand bags and rebar. Half of an acre was matted with 93 mats, held down with 2,500 pieces of rebar and 1,000 sandbags. The plan is for the mats to stay in through the winter and to be removed in the spring prior to Memorial Day.
This is the only Asian Clam site being treated this fall. Research is also underway to better understand the small, juvenile clams and how the clams are spreading around the lake. The Glenburnie site was surveyed by scientists at DFWI for juvenile clams prior to treatment, and none were found. So it is a good candidate for treatment. The benthic barrier method developed by the Task Force over the past few years works well for killing adult clams, but clam infestations are still spreading. One likely explanation is that small, juvenile clams (less than 2 mm in size) that have been released prior to matting efforts might be to blame for the continued infestations. So the Task Force has asked DFWI to help it better understand how the clams are behaving in the Lake.
