Tackle Invasive Species

Aquatic invasive species (AIS), introduced to Tahoe by humans, have taken over areas of Lake Tahoe and are changing the Lake we know and love. These plant and animal invaders are degrading water quality, disrupting the Lake’s ecology and opening the door for more invasive species to take hold. Warming waters caused by climate change are creating more habitat along Tahoe’s shoreline for AIS to take over. We see the impacts where most of us enjoy the Lake, on the beaches and nearshore, which are becoming choked with AIS. The League is working to keep AIS in check through constant monitoring, deploying innovative control methods and responding quickly to any new infestations discovered.

The League to Save Lake Tahoe and our partners in the Lake Tahoe Aquatic Invasive Species Coordinating Committee have collaborated to produce an annual summary of the current threats to Tahoe from aquatic invasive species.
