It is a well-known fact that California Department of Fish and Wildlife fits black bears with GPS collars to track their movements — but at what cost? One down side is the assumption by the public that a bear with a collar is a 'nuisance, problem. rogue or dangerous bear' which isn't true (Those bears are killed, Not collared). When people think the bear is a troublemaker, they will automatically disrespect, fear him and want him Gone.
To install the collar, the bear must be heavily sedated, sometimes for hours at a time, until the collar is fitted (at times they are so heavily sedated they die).
As bears grow larger each year in preparation for hibernation, these collars cause restricted movement, skin irritation, and--as these images show--serious, life-threatening infections and injuries. Younger bears are especially vulnerable, as collars can embed deep into the bear’s neck as they rapidly grow, causing infections and death.
Although the collars are designed to fall off by themselves after a period of time, they often fail and BEAR League has seen these collars remain on bears for years.
While BEAR League appreciates and encourages science-based education regarding black bears in California, wildlife should be monitored with their well-being in mind, not despite it.
The good news?
There are humane alternatives that work.
Bear biologists can use camera networks like BEAR League uses to monitor bear activity and populations without physical contact. In South Lake Tahoe alone, BEAR League has images of dozens of bears and we regularly track them as they travel through the area.
BEAR League is also currently working on developing facial recognition software for use with bears to allow more reliable tracking from our bear images.
There are also small GPS tags that attach to the bear’s fur that have successfully been used with polar bears in Canada.
Please consider contacting CDFW’s Executive Director Meghan Hertel at https://wildlife.ca.gov/Director/Email to strongly and diplomatically suggest CDFW adopt 21st-century, cruelty-free monitoring methods. Science and compassion aren't mutually exclusive.
