The endless fight against invasive species continued apace in 2021. 

Some new invasive species inched into the Adirondack Park, while some continued to unsuccessfully seek a foothold – like hydrilla, which was intercepted by Adirondack Watershed Institute boat stewards during the summer. 

Gov. Kathy Hochul signed legislation making permanent rules against transporting aquatic invasive species and authorizing DEC to establish more boat inspection and decontamination stops in the Adirondacks. After another year of boat inspections across the park, boats were buoyed by increasing compliance among the public and decreasing rates of identifying invasive species.

The state also ramped up its fight against the hemlock woolly adelgid, an invasive bug that has established itself around Lake George and threatens the region’s iconic hemlock trees. Scientists with the New York State Hemlock Initiative at Cornell University helped kickstart an offensive attack on the invasive bugs: release the biocontrols. They are letting predator bugs to fight the invasive bugs. Those battles will continue for at least five years.
