Overview
Basics
Basics
This project will implement underwater surveys for Asian clams in Lake Tahoe Nevada State Park at Sand Harbor to determine recolonization rate following treatment and delineate current extent of the invasive Asian clam populations. Surveying and continued monitoring will take place over three years, with number of dead and live clams recorded at each dive’s conclusion. Unmanned aerial vehicle (UAV) flights will also be conducted to obtain aerial data on metaphyton coverage, and remote sensing of the clam survey area with UAV imagery will be used to assess potential growth of metaphyton associated with clam populations.

Threshold Categories
-
Assessment of Asian clam populations is the first step towards removal of non-native species, helping restore and enhance lake habitat.
-
Documentation and removal of aquatic invasive species leads to an improved recreational experience for visitors to Lake Tahoe.
