New York's Lake George mats wiped out 97% of invasive Asian clams in 2011

Lake George in New York deployed benthic barrier mats across a five-acre area in 2011 to combat an invasive Asian clam infestation. The large-scale treatment proved highly effective, eliminating 97% of the clam population. However, the success was not permanent, as the clams staged a comeback by 2019, with 27 affected sites identified across the lake. Authorities have since shifted their focus from eradication to monitoring the spread of the clams and assessing their impact on the local ecosystem.
