In the summers of 2005 and 2006 ASRA staff cooperated with the Adirondack Nature Conservancy (ANC) to inventory invasive species along the East Branch Au Sable from Hulls Falls Road to Au Sable Forks. 214 terrestrial invasive plant sites were found consisting of Purple loosestrife, Japanese knotweed, wild chervil, and Japanese barberry. In addition, 94 of the 214 infestations were Indian Cup-plant, Sylphium perfoiatum. Indian Cup-plant was also noted as far downstream as Keeseville.
Summer 2007 found the ASRA and ANC staff once again wading and paddling through streams to map invasive, this time on the West Branch. On Mill and Power Ponds of the Chubb River (a West Branch tributary) 17 sites covering 64,000 square feet were documented. There were no invasive noted on the Chubb or West Branch downstream of the ponds until Lake Everest in Wilmington where 5 sites totaling 2,607 spare feet were noted.
ASRA in coordination with BRASS and local fly-shops, launched a campaign to keep Rock Snot (Didymo) out of Adirondack Rivers. Rack cards that describe Didymo and provide information on how to clean fishing gear and clothing have been produced. These cards have been distributed all over the Au Sable and boquet Watersheds and as far south as the BattenKill River. In addition, the river association produced flyers that were distributed across the state to be posted along the infected and uninfected rivers.
