With the historic Rim fire in Tuolumne and Mariposa counties still burning, the California Department of Fish and Wildlife (CDFW) is reminding hunters about limited access and road closures in the Stanislaus National Forest.

The still burning wildfire is the third largest ever recorded in California. CDFW implores that all outdoorsmen and outdoorswomen to be good stewards of the state’s wildland resources and obey all laws and restrictions regarding uses of valuable public land forests and ranges.

Deer hunters deal with wildfires and their impacts on hunting access nearly every year. Fish and Game Commission (FGC) regulations prohibit CDFW from allowing a hunter to exchange a deer tag after the earliest season (archery or rifle) has opened or if the tag quota for the zone has filled; and prohibits CDFW from issuing a refund to hunters after a season has started.

Archery deer season was underway when the fire started and so exchanges or refunds cannot be issued. CDFW staff will be reviewing our regulations to assess whether in 2014 we can recommend an approach to the FGC that would not inadvertently penalize hunters when such events occur.

CDFW considered recommending an emergency closure of the hunt zone for species conservation. The department chose not to because deer are an adaptable species that evolved with wildfire in the Sierra Nevada, that deer for the most part, had the capability to escape the fire, that the majority of the deer population in the area are female (does) and are not hunted anyhow, and that part of the zone remains unaffected and could be hunted. Typically in the Sierra Nevada, deer populations respond favorably to large wildfires because of the abundant growth of new herbaceous and shrub vegetation that deer rely upon. CDFW is cautiously optimistic about deer response to this fire in the coming years, while recognizing other environmental factors may influence herd productivity.

Many areas of the Stanislaus National Forest will be closed to public access on the opening weekend of zone D6 general deer season which starts on Sept. 21. Closures are in effect to protect firefighters in their suppression efforts as well as the public from hazards that exist in a recently burned area. CDFW is making recommendations to the Stanislaus National Forest on suitable areas to re-open once conditions permit, as well as on evaluations of fire damage and habitat restoration.

The closures will likely impact all types of hunting and other recreational activity for an extended period of time. Hunters should check the Forest Service websites listed below for the latest information before heading out.


Information on closures can also be obtained at the Ranger District Offices during regular business hours, or by calling the Stanislaus National Forest prior to traveling to the forest. In areas that are open, there are campfire restrictions in place and no open fires are allowed outside of the developed campgrounds.

The Power Fire, which was north of Highway 108 and east of Pinecrest also has a closure area. This fire started on Aug. 5 and is reported to have burned 1,070 acres. Although the fire is 100 percent contained, there is a temporary closure in place until the fire is declared out.

Deer Hair-loss Syndrome Challenges California Researchers

Low Fawn Survival Rate Impacts Population

Researchers at the California Department of Fish and Wildlife (CDFW) are studying a deer hair-loss syndrome across the state.

Wildlife experts are calling the issue “hair loss” but the real problem appears to be from the infestation of non-native lice and in some cases, a heavy infestation of internal parasites. Symptoms range from a scruffy looking hair coat to near complete baldness. Hair–loss syndrome is also associated with poor nutritional condition, making it difficult for fawns to survive to replace the normal mortality in mature deer.

“Some of us speculate that the louse-infested deer spend so much time grooming they become easy targets of predation by coyotes or mountain lions,” said CDFW senior wildlife biologist, Greg Gerstenberg. “While this theory is still under investigation, what we do know is that the louse has impacted migratory populations of California deer which now have a low fawn survival rate, making it difficult to replenish the herd.”

The goal of the research is to understand why the lice infestations are appearing as well as to understand the full impacts of the non-native louse species and hair loss. Information is also being shared with other western states that have similar issues in order to identify trends and potential treatments.

It has been speculated that this condition may be attributed to an environmental deficiency of copper or selenium or some other underlying environmental factor such as a difficult to detect disease agent,” said CDFW state veterinarian, Pam Swift. “Regardless, we are conducting a comprehensive coordinated effort that will hopefully shed some light on this perplexing syndrome and minimize its effect on California’s precious deer population.”

To date, researchers have successfully captured and collected hair and blood samples from more than 600 deer and elk across California. Counting and identifying lice on each deer, applying radio collars to track the deer, and treating some deer for lice will hopefully give researchers some quantifiable information they need to identify trends and find a solution.
