S. Sierra Nevada Fisher Population Stable

ScienceDaily reported on a recent study that found the fisher (Martes pennanti) population of the Southern Sierra Nevada has been stable from 2002 to 2009. This is good news after years of population declines.

The fisher is in the weasel family and is about cat size. They originally had lived throughout most of the mountains in northern California and the Sierra Nevada as well as the Rocky Mountains, Cascades and Coast ranges. However, populations were devastated from commercial trapping and clear-cut forestry practices.

The southern sierra is the home of about 250 individuals including the only two remaining native populations. Fishers have also been reintroduced in a few western U.S. locations. Read more at ScienceDaily: Stable fisher population found in the Southern Sierra Nevada.
