[edit]Description101031-A-6479G-078 (5133291081).jpg | MARTIS CREEK LAKE, Calif. (Oct. 31, 2010) - Phil Caterino of the Tahoe Divers Conservancy holds invasive Eurasian watermilfoil plants here Oct. 31. Volunteers helped assemble and set sunlight barriers as part of a project to eradicate the plants from the lake bottom. The gas-permeable barriers kill the milfoil plants by blocking sunlight, but don't disturb other plant and animal species native to the lake. The Corps is partnering with the Tahoe Divers Conservancy on the project, funded by a $20,000 grant from the Community Foundation of Western Nevada's Truckee River Fund. |
