Update on Thomas Fire "Tilapia Bears"

We have an update on the two black bears that were burned in the Thomas Fire in late December/early January! Both bears were suffering from extensive burns to their paws when they were brought to CDFW’s Wildlife Investigations Lab in northern California. Under the care of CDFW Senior Wildlife Veterinarian Dr. Deana Clifford and Dr. Jamie Peyton of the UC Davis Veterinary Medical Teaching Hospital, the bears were given an unusual experimental treatment involving the use of sterilized tilapia skins as bandages. After the bears were well enough to survive on their own, they were returned to the Los Padres National Forest, as near as possible to where they were originally found. Both have covered many miles and each has been spotted at least once since their release.

Scientists Battle Mange Outbreak in Urban Kit Fox Population

Specify Alternate Text
Fate has not been kind to the San Joaquin kit fox (Vulpes macrotis mutica). Shrinking habitat caused by urbanization and agricultural expansion landed this Central Valley native on the federal Endangered Species List decades ago. California’s total population of San Joaquin kit foxes may now be down to a few thousand animals. To make matters worse, its favorite food, the kangaroo rat, is likewise endangered as the desert habitat it prefers continues to disappear.
