Habitat is the key to the long-term survival of Sacramento River winter-run Chinook in California. Since 1999, CDFW has been working with multiple agencies and private parties on planning efforts to restore the population of these endangered salmon. More than $100 million has been allocated to specific habitat restoration work on Battle Creek, which comprises approximately 48 miles of prime salmon and steelhead habitat.

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.
