Last winter’s drought-busting wet weather was a boon for reservoirs and parched landscapes, but not so much for some invasive species in San Francisco Bay, according to a long-term study by Tiburon-based researchers. All that fresh water that poured into the bay was bad news for certain invaders, which have turned up in droves in recent decades from around the world, often in ships’ ballast water.
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.”
