Rat poison used in marijuana grows harming wildlife
The fishers are being monitored by a team of scientists affiliated with the Sierra Nevada Adaptive Management Project (SNAMP), a joint effort by the University of California, state and federal agencies and the public to study management of forest lands in the Sierra Nevada.
To learn the animals' habits and habitat, the SNAMP wildlife team has placed radio-tracking collars on about 100 fishers over the years, with around 30 collared at any given time. When animals being monitored die, they are collected to determine the cause. Anti-coagulants were found in the livers of 90 percent of the fishers.
A likely source is rodenticides left behind at illegal marijuana grows in the forest, the article said.
"SNAMP discovered the rodenticide poisoning issue in the fisher population, and we knew we needed to find some money to clean up the raided sites," said Anne Lombardo, SNAMP representative based in Oakhurst, Calif. "That's our contribution to putting science on the ground."
Nov. 5 - 14 about 100 volunteers and agency personnel cleaned up 13 Sierra Nevada marijuana cultivation sites to restore habitat, and remove risks to wildlife. The teams dismantled and remediated sites previously raided or partially cleaned up, and documented and removed all toxicants found.
