When conditions are right, winter can be a good time to conduct prescribed burns for forest management, says Rob York, UC Cooperative Extension forestry specialist.
“A huge issue we have in California is fire severity. We know from research that prescribed fire can be a very good tool for reducing fire severity,” York said. “For forest landowners or foresters who want to do their own prescribed burning, winter burning can be a good entry point.”
York is based at the UC Blodgett Forest Research Station in Georgetown, where he developed a series of eight short videos demonstrating how fire can be used on landscapes during the colder months. The videos...

UC Master Gardener Francie Murphy was pruning the succulents in her San Diego front yard when an unfortunate accident catalyzed her commitment to communicating the dangers of toxic plants. She trimmed a stem on her drought-tolerant pencil milk bush and milky sap spurted into one eye, causing stinging pain.

A nearby friend rushed her to the emergency room where the doctor diagnosed chemical burns to her corneas and washed her eyes with two liters of saline water each. Murphy removed the plant from her garden, but saw it growing throughout her...

As winter turns into spring, Southern California residents who live in areas where the red imported fire ant has taken hold will want to keep a close eye out for colonies establishing themselves in lawns, parks, schools and golf courses.
Red imported fire ant (RIFA) arrived in California in 1989, and is widespread in residential and commercial areas of Orange, Riverside and San Bernardino counties, and adjoining areas of Los Angeles County. True to its name, the fire ants inflict painful, burning stings when they crawl onto people working, walking or resting on infested turf grass and other outdoor areas. For some people, RIFA bites and stings can lead to life-threatening anaphylactic shock.
RIFA is difficult to...
