Even though California's majestic oak trees are generally considered drought tolerant, the last four years of well-below-average rainfall are taking a toll, reported the Sierra Sun Times.
"In some parts of the state, oaks are being deprived of water for as long as nine months, creating extreme water stress," said Greg Giusti, a forest and wildlands advisor for UC Agriculture and Natural Resources. Giusti is headquartered in the UC ANR Cooperative Extension office in...

The cover story in the Feb. 4 edition of the color magazine New Times is a well-written 2,300-word history of Avenales Ranch, east of San Luis Obispo, which has been the site of UC collaborative research for decades.
The story centered on 92-year-old family patriarch Jim Sinton, who inherited the 12,000-acre ranch from his grandfather.

UC Berkeley Cooperative Extension natural resources specialist Doug McCreary knew it was a matter of life or death . . . . This spring, landowners were wondering whether they should yank out oak trees that were uncharacteristically brown or bare.
McCreary took quick action to save trees' lives. He gathered information for a news release assuring people the die-back was probably not a sign of Sudden Oak Death and urging them to wait at least a year before pulling out trees. The story was picked up by the Associated Press and run in several Northern California newspapers, including the
