Tackling Invasive Species

Aquatic invasive species — including a pair of water plants originally introduced to North America as decorations for fish tanks — have already established themselves in Lake Tahoe and are changing the Lake’s environment in ways that lead to clarity loss while producing conditions that make it easier for other non-native to establish themselves and outcompete native species. Identifying and controlling all unidentified infestations of non-native species is a task beyond the resources of Tahoe’s public agencies.

The League has made tackling invasive species a top priority, and there is a role for you to help Keep Tahoe Blue.

We’re collaborating with Tahoe’s public agencies at the highest level. Our staff now participate in all meetings of the Lake Tahoe Aquatic Invasive Species Coordinating Committee, which makes all the decisions regarding the control of existing non-native species and efforts to prevent new infestations.

We’re educating and engaging the public. The League’s Eyes on the Lake program trains visitors and residents to identify the two most common non-native aquatic plants: curly-leaf pondweed and Eurasian watermilfoil. The program gives people the skills needed to spot new shoreline infestations while they’re out boating, swimming, fishing, paddling on their stand up paddleboards, or lounging on the beach.

As an outcome of our involvement in the AIS coordinating committee, our fellow committee members have asked to receive our Eyes on the Lake training, and the EOL program has been incorporated into the Lake Tahoe Invasive Species Management Plan.

We’re advocating to ensure we get the best plans to manage invasives in Tahoe. League staff experts now have a key role in reviewing all implementation plans for the control of aquatic invasive species for the Lake, including the forthcoming plan for the Tahoe Keys. In a related collaboration, this will be our second year partnering with the Tahoe Keys Property Owners Association, whose homeowners have been participating in our invasive species trainings. We are hosting more trainings with the Keys homeowners this summer.

Aquatic invasive species are here in Tahoe, but through the League’s efforts to advocate for solutions, collaborate with our partners, and educate and engage the public, we are hopeful that we’ll prevent the invading non-native species from taking over in Tahoe. Invasive species are a serious threat to Tahoe’s clarity and ecosystem. League programs to tackle invasive species include:

Eyes on the Lake is a volunteer program in which water recreationists report information about locations of aquatic invasive species. Swimmers, boaters, snorklers, SCUBA divers and fishermen are all welcome to join the effort.
