California has abundant wildlands — forests, rangeland, open areas, wildlife refuges and national, state, and local parks — that need protection from invasive plants. Invasive plants affect all Californians by increasing wildfire potential; reducing water resources; accelerating erosion and flooding; threatening wildlife; degrading range, crop and timberland; and diminishing outdoor recreation opportunities. According to the California Invasive Plant Council (Cal-IPC), more than 200 identified plant species harm California's wildlands.

When wildfires burn in California, people often call them forest fires or brushfires, but the odds are high that an invasive weed is an unrecognized fuels component, says a UC Agriculture and Natural Resources scientist.
“We have all of the nasty non-native Bromus species here in California, and these weeds are key drivers of increasing fire frequency,” said Travis Bean, UC Cooperative Extension weed science specialist based at UC Riverside.
The invasive, non-native Bromus species aggressively outcompete native plants, forming dense stands that grow fast and dry out quickly, becoming highly flammable. Fire can move rapidly through these...

Weeds are a pervasive and expensive problem in California. They can choke waterways, crowd out native species on rangeland, and rob farmers of crop yields. According to the California Invasive Plant Council, the annual cost of invasive plant work in California is at least $82 million.
The University of California has robust educational resources to help those engaged in the battle, and this summer UC Davis and UC Agriculture and Natural Resources personnel are offering a trio of programs to help in the effort.
Weed Day: July 7, 2016
The 60th annual Weed Day will be held at UC Davis on July 7 from 8 a.m. to 4:30...

Most people deal with ants around their home at some point. Because most ants live outdoors, focus efforts on keeping ants from entering buildings by caulking entryways. Follow good sanitation practices to make your home less attractive to ants. Spraying ants inside the home will not prevent more ants from entering. Use baits to control the ant colony. Pesticide baits work by attracting worker ants who then take the poison back to the nest where the entire.../h3>/h2>

Weeds don't just look unsightly, they are also robbing other plants of water, says a UC Agriculture and Natural Resources (UC ANR) expert in a new water conservation video released today.
Any loss of water is a concern as California's fourth summer of drought comes to a close. Missy Gable, director of the UC Master Gardener Program, suggests removing weeds so they won't compete with ornamental plants or edible vegetables.
If weeds are scattered throughout yard and mixed in with plants, hand-weeding is probably the best eradication method. Cultivation can damage ornamentals with shallow roots, bring weed seeds...
