CDFW Captures Tule Elk in Phase One of Multi-Year Study in Colusa and Lake Counties

Specify Alternate Text
The California Department of Fish and Wildlife (CDFW) recently launched the first phase of a multi-year study of tule elk in Colusa and Lake counties. In partnership with the University of California, Davis and the Rocky Mountain Elk Foundation, and with the assistance of capture specialists from Leading Edge Aviation, researchers used helicopter net guns to capture and place satellite collars on 45 tule elk.

Pronghorn Study

Specify Alternate Text
Pronghorn antelope (Antilocapra americana) were once one of the most numerous large mammals in California, with populations estimated to have been as high as 500,000 prior to the Gold Rush era. In the mid-1800s, pronghorn were nearly extirpated by market-shooting to feed California’s rapidly expanding human population.

California's White-footed Vole

Specify Alternate Text
The white-footed vole is one of the least-studied (and most difficult to catch!) mammals in North America. CDFW Environmental Scientist Dr. Scott Osborn, his collaborator Dr. Tim Bean of Humboldt State University’s Wildlife Department, and a small team of field biologists know that better than anyone – they spent the summer of 2014 setting traps for them in Humboldt and Del Norte counties. Designated a Species of Special Concern by CDFW, only nine records of the species were known in California prior to their study, which was aimed at determining how environmental conditions, such as climate (and future climate change), might affect their distribution.
