When a volunteer pulled a suspicious clam from the lakebed in Whitehall, New York, as part of a routine monitoring program last month, they immediately reported the find to lake scientists. Further analysis confirmed the first known occurrence of invasive golden clam (Corbicula fluminea) in Lake Champlain.

The clam, which is native to the eastern Mediterranean and Asia, can crowd out native species and increase occurrences of cyanobacteria blooms.

Vermont’s Noxious Weeds Quarantine rule was adopted in 2002, and most recently amended in 2012, and is implemented by the Agency of Agriculture, Food and Markets under its statutory authority. The rule regulates the importation, movement, sale, possession, cultivation, and/or distribution of certain plants known to adversely impact the economy, environment, or human or animal health.

The Vermont Department of Environmental Conservation (VTDEC) Lakes and Ponds Aquatic Invasive Species Program is excited to launch a brand-new community science project this summer, 2022 called the Vermont Invasive Patrollers for Animals Program

Craspedacusta sowerbyi, or peach blossom fish or simply freshwater jellyfish, are indigenous to the Yangtze River in China and were first observed in Vermont in 1999. Since 1999, freshwater jellyfish have been spotted in several Vermont lakes, ponds, and river across the state, so how were they introduced and are they a threat?
