A pair of orphaned Pacific fisher kits live in an incubator at the Fresno-Chaffee Zoo. Researchers were able to rescue the kits when a collared female sent out a mortality signal. She had likely died from an attack by a predator. But with Pacific fisher, especially these members of the southern Sierra population, every death counts. Only about 300 remain. Mourad and Greta's studies have shown that 100 percent of fisher tested now come back positive for rodenticide and other chemical exposures associated with trespass marijuana grows. The fisher was recommended for listing as threatened under the Endangered Species Act in 2016, but in its final stage of approval, U.S. Fish and Wildlife reversed its decision, declaring the fisher not warranted for consideration, even though toxic poisonings from trespass grows had reached tipping point levels for the population. The same day Weyerhaeuser Company, one of the largest timber companies in the world announced it was creating a conservation easement for Pacific fisher. In Sept., of 2018, a federal judge ruled that U.S. Fish and Wildlife had erred in their reasoning, failing to adequately take into account the impacts of poisoning from trespass grows. He ordered the agency to conduct a new assessment. These kits were eventually released in Yosemite National Park.
