USDA announced last week that UC Davis and UC Berkeley are among 13 research universities across the country that will receive funds to develop ecologically and economically rational strategies for management, control or elimination of weedy or invasive species.

Nearly $500,000 will go to the Davis laboratory and $500,000 to a UC Berkeley laboratory. The 13 university recipients are sharing $4.6 million in all.

"Invasive plants and animals are a major threat to food and fiber production, costing U.S. producers between $7 billion and $27 billion per year, but by doing research on controlling and managing weedy and invasive species we help protect the productivity of America's farmers and ranchers," a USDA news release quotes agriculture secretary Kathleen Merrigan.
