Rat poison from illegal California marijuana grows threatens rare forest animals

While the stereotypical image of marijuana farmers depicts them as Earth-friendly environmentalists, a proliferation of less scrupulous growers using rat poison to ward off pests on illegal farms may be responsible for killing scores of rare weasel-like mammals called fishers, which are already on the verge of protection under the Endangered Species Act.

As reported by the Summit County Voice, a new study by researchers at UC Davis, the Integral Ecology Research Center and other land agencies found that almost 80 percent of the fisher carcasses studied had been exposed to anticoagulant rodenticides. Brodifacoum, a second-generation rodenticide, was found in 96 percent of the dead animals. The researchers are looking at illegal public marijuana farms as the source for introducing the toxic chemicals to the remote, wooded areas where fishers dwell. The animals are often attracted by bacon and peanut butter “flavorizers” added for that very purpose.
