The California Department of Fish and Wildlife hit a milestone in its ongoing efforts to control the state’s nutria infestation on Friday morning when they successfully trapped Nutria number 300 at a pond in Merced County. … The department is currently expanding its operations in San Joaquin County, and is concerned by several reports of nutria on the doorstep of the Sacramento–San Joaquin River Delta, a critical region for California’s agricultural infrastructure.
Invasive zebra mussels are threatening an underwater historic preserve in Lake Champlain. The preserve maintained by the Lake Champlain Maritime Museum is made up of nine Vermont vessels and one New York vessel, all of which can be explored by divers.
Having been hauled thousands of miles from across the country, a pontoon boat bound for a weekend on Lake Tahoe pulls into the Alpine Meadows Watercraft Inspection Station. It’s one of roughly 8,000 motorized vessels that were inspected during this past boating season, and one of more than 5,000 that did not meet Lake Tahoe’s Water Inspection Program’s standards of being clean, drained and dry.
Agencies from San Joaquin and Contra Costa counties to NASA and the U.S. Department of Agriculture formed an invasive-weed task force seeking holistic, more comprehensive solutions to free the Delta from its oppressors.
“Species of plants and animals are becoming extinct at least 1,000 times faster than they did before humans arrived on the scene, and the world is on the brink of a sixth great extinction, a new study says.”
From the Lake Tahoe News, in a commentary by Joanne Marchetta:
“When the Tahoe Regional Planning Agency and partner agencies started inspecting Lake Tahoe watercraft in 2008, all we knew was that we needed to protect our waters from the growing threats of aquatic invasive species. We took the necessary steps, but did not know then that the watercraft inspection program would one day help protect other water bodies as well.
“A mandatory boat inspection program continues to pay dividends for Lake Tahoe, a conservation agency said, as 36 boats harboring invasive plants, mussels and snails were prevented from entering the lake in 2013.”
