Have you heard of the UC ANR California Naturalist Program? This new UC ANR program fosters a diverse community of naturalists and promotes stewardship of California's natural resources through education and service. Designed to introduce Californians to the wonders of our unique ecology and engage volunteers in stewardship and study of California’s natural communities, California Naturalist provides hands-on instruction and exposure to real world environmental projects designed to inspire adults to become active citizen scientists and enhance their personal.../span>

Rodenticides used on illegal marijuana farms have already been shown to pose serious harm to the fisher—a cat-sized carnivore found in forests across Canada and four regions in the U.S. (Previous news article.)
Mourad Gabriel, a doctoral candidate with the Veterinary Genetics Laboratory at UC Davis School of Veterinary Medicine, provides a more comprehensive look at the situation in the recent issue of...

California’s Central Valley is home to a rich diversity and solid abundance of birds. Many are year-round residents, while others are migrants that winter in our valley or travel to destinations further south. Currently more than 400 species of birds call the Central Valley their home; these include raptors, songbirds, ducks, geese, shorebirds, hummingbirds, and others. (Download a checklist of Central Valley birds here.)
All birds depend on habitat for food, shelter and nesting sites. With a decline in habitat in the Central Valley, primarily due to agricultural expansion, urbanization and water diversions, there has been a significant decrease in...

Rat poison used on illegal marijuana farms may be sickening and killing the fisher, a rare forest carnivore that makes its home in some of the most remote areas of California, according to a team of researchers led by University of California, Davis, veterinary scientists.
Researchers discovered commercial rodenticide in dead fishers in Humboldt County near Redwood National Park and in the southern Sierra Nevada in and around Yosemite National Park. The study, published July 13 in the journal PLoS ONE, says illegal marijuana farms are a likely source. Some marijuana growers apply the poisons to deter a wide range of animals from encroaching on their crops.
Fishers in California, Oregon and Washington have been declared a...

UC scientists with the Sierra Nevada Adaptive Management Project (SNAMP) are investigating the uses of Lidar (light detection and ranging) in providing detailed information on how forest habitat is affected by fuels management treatments across a large landscape. Mapping forest structure can illustrate how a forest influences surface hydrology, provides for wildlife and how a forest might burn given certain weather and wind patterns. This research is proving useful in wildlife studies, water quantity and fire modeling and forest planning.
Airborne lidar works by emitting a light pulse from an emitter onboard a plane towards a ground target. A portion of the light is reflected back to...
