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...

Thank you 185 times over!! The wildlife research team from the Sierra Nevada Adaptive Management Project recently put out a request for the donation of single socks. They use them to hold bait for their camera trap studies of the Pacific fisher. The response was overwhelming and the fisher research team would like to thank all of the people who sorted, dropped off or packaged, waited in line and mailed their recycled socks to them. Your commitment and follow through are remarkable!
The team first got bags of socks from the local high school, and then grocery bags of socks started appearing in a local drop off bin. Soon boxes of socks started arriving by mail. They came from all over...

A University of California wildlife research team working in the Sierra Nevada near Oakhurst, Calif., is asking the public to donate clean, gently used socks for research on a rare weasel called the Pacific fisher. The team is part of the Sierra Nevada Adaptive Management Project (SNAMP), which is examining the effects of forest thinning, as currently done by the U.S. Forest Service, on the health of local wildlife, the forest and water resources. The U.S. Forest Service implements these treatments out of concern for excessive fire risk. Eighty years of fire suppression, reductions in logging and drought conditions have left the forest increasingly overcrowded and excessively...

“Water is the driver of nature.” - Leonardo da Vinci
California’s vast dry rangelands are dotted with water troughs ideal for quenching cattle’s thirst. But in most cases, the troughs’ designs are a torment to wildlife drawn for a drink.
Monterey County rancher George Work observed how traditional water troughs frustrated the wildlife on his family’s 12,000-acre cattle ranch. Small birds couldn’t reach water two or three inches below the top edge. Coyotes, bobcats and cottontails weren’t tall enough to reach over the rim. Work set to making a water trough that would meet the needs of all animals on the range – from cattle, hunting dogs and horses to deer and rabbits.
While raising cattle remains...

The UC Berkeley Sierra Nevada Adaptive Management Project (SNAMP) Fisher Team has just finished closely monitoring reproductive-age female Pacific fishers living in the Sierra National Forest near Bass Lake for the spring 2011 denning season. Each year the denning season for fishers starts around late March and ends in mid June.
The fact that one of the study's radio-collared female fishers moved her kit from a natal den tree (where the kits were born) in the Sierra National Forest to a maternal den tree in the Mariposa Grove area of Yosemite National Park was a highlight. The event was significant for the park service because it represents the first known fisher den tree...
