Event Details

The wolverine (Gulo gulo) is the largest of the 9 mustelid species that naturally occur in California, and unfortunately, is also the rarest. Based on the combined efforts by multiple Researchers surveying for Predators in the State’s montane regions, our current evidence is that California is home to a single wild wolverine. Katie Moriarty, a Graduate Student, made the discovery of the lone wolverine in February 2008 while researching the Pacific Marten (Martes caurina) in the Tahoe National Forest. This surprising discovery was the first verifiable account of a wolverine in California since 1922, and further genetic analysis indicated it is a male wolverine related to populations found in the Sawtooth Mountain Range of western Idaho.

Since this discovery, a handful of biologists continue to monitor this wolverine, each year confirming its continued existence in the region of the original discovery, and for the hope a second wolverine (i.e. a mate) is discovered. The focus of this presentation will be on the CDFW’s ongoing monitoring efforts of this wolverine, and additional multi-species predator monitoring throughout the Sierra Nevada, which in addition to gaining a better understanding of montane predator ecology, also helps to confirm whether additional wolverines occur in California. This is critical information as the Department investigates the viability of reintroducing this animal back into California.
