Marin's 2-Pound Bigfoot



There's a furry beast lurking in Marin's darkest corners, living in self-made tunnels snaking through the County's densest brush and chapparal. It's that shadow you can't quite see, that fleeting "what was that?" as you turn the corner on a lonely trail, the phantom of Pt. Reyes.

Okay, perhaps I oversell a bit. After all, this "beast" weighs in at a modest 1 to 2 pounds, has almost no snout and a little wudge of a tail, and, even if it stands on its hind paws, would probably not be able to sniff your knee.


It's a beaver, a mountain beaver to be exact, which isn't really a beaver but a muskrat-size rodent with large teeth, dull brown fur, and a propensity for soft greenery like the young cow parsnips and fern fronds poking up all over Pt. Reyes National Seashore right now. As a lifelong resident of Marin, I'd never even heard of these little critters, scientific name Aplodontia rufa phaea, but I prefer mountain beaver or another endearing nickname, "ground bear." That moniker would fit the little bundle that I saw scurrying across the trail as I climbed up the Drakes View Trail on Mt Vision at Pt Reyes last weekend.

Apparently I'm very lucky to have seen it. The mountain beavers at Pt Reyes are a very select subspecies of mountain beaver--they aren't found anywhere else. And they were almost wiped out by the 1995 Vision Fire; apparently retreating to a little burrow carved out of blackberry brambles and coyote brush isn't a good place to retreat in a wildfire. Of the roughly 5,000 individuals that called Mt. Vision home, less than 20 were estimated to have survived. Less than 20. Maybe I saw one of those hardy (or just lucky) originals. Maybe one of their babies, or grandbabies. All I know is I hope to see more. Marin needs more ground bears and mini-Sasquatches.

  1. Good post.

    Not likely that any of the animals that survived the Mt. Vision fire are still alive. The fire did destroy much of the habitat there and most of the population which has been slowly recovering. I've been interested in this little known species for quite a while now and collect information on it in this "journal" http://homepage.mac.com/dtsteele/Mountain_Beaver_Work/pages/34.html

    Thanks, Dale
