Wolverine Photographed in Rocky Mountain National Park

Share

The wolverine is a fast-moving wanderer. Thinkquest photo.

A wolverine has turned up in northern Colorado and was recently photographed in Rocky Mountain National Park. It’s been a very long time since a wolverine has prowled this terrain.

It can create quite a stir when species that were regionally extirpated long ago are once again seen in their former haunts, especially when they show up without benefit of human assistance. Such was the case, for example, when a lynx was photographed in Yellowstone National Park in November 2007..

We’d like to think that our national parks could once again have their full complement of native species, so there’s an extra measure of satisfaction when a species shows up of its own accord in one of these special places. These events not only provide tangible evidence that we are doing a good job of habitat preservation in our national parks, but also serve as touchstones of progress along the way to the restoration of “whole ecosystems.”

Now a wolverine has been photographed in Rocky Mountain National Park, a place where no wolverine has been seen – at least not for certain –since the park was established in 1915. Thanks to this verified sighting, 2009 will now go down in the books as the year that wolverines returned to northern Colorado and to Rocky Mountain National Park. Well, at least one wolverine that we know of.

Where this particular wolverine came from is not a mystery. Earlier this year it was radio-collared for research purposes (the Greater Yellowstone Wolverine Program) in the Yellowstone ecosystem way up in northwestern Wyoming. An adult wolverine like this one would be a compact, muscular animal weighing about 30 to 40 pounds and stretching to about three or four feet in length, tail and all.

This wolverine managed to travel around 500 miles into northern Colorado over a period of several months. Wolverines are fast-moving, notorious wanderers, but they are also reclusive and don’t like to be around people. Even by wolverine standards, this particular journey, which involved crossing Interstate 80 and dealing with numerous other hazards, was an amazing feat.

One of the people who saw the wolverine in the park was a wildlife photographer who managed to get a good picture of it – radio collar and all -- at a place above the treeline not far from the park’s Trail Ridge Road. Hard evidence like this is rare, and wildlife biologists are delighted to have it.

Where this wandering wolverine might turn up next remains anybody’s guess. An even better question is whether there are other wolverines in northern Colorado, and when a breeding population might be established. There’ve been no breeding populations of wolverines anywhere in California, Utah, or the southern Rockies for nearly 80 years.

My brother and I were fishing at Estes Lake and we saw what looked like this one.I was pretty sure it was a wolverine.This was last year,'08 in Aug.


I take it that you didn't get the chance for a photograph, J. How close were you to the animal? Did you happen to notice whether it was wearing a radio collar? This particular wolverine was in Yellowstone just a few months ago.


I was about fifteen feet from it.We were fishing the shore in the park by the outlet towards town.We didn't notice a radio collar and I didn't think to use my phones camera.It went into a bush and then reappeared about a half hour later.It was headed across the picnic area towards the road.I thought it might have been a badger but when I got home I looked it up and was convinced it was a wolverine.So interesting to come across this article.


Here is a link to the website of the photographer who got the shot of the wolverine in RMNP - http://www.ray-rafiti-photography.com/-/ray-rafiti-photography/gallery.a...


Well that looks like the critter I saw.We had the dog chained to the trucks bumper and she went nuts.We couldn't figure out why till a paserby pointed towards it.I'm from MA and have never seen one up close but will testify that's what I saw.The second time when it left the bush leaving it postured like a Komdo Dragon.That was because the dog was on alert.So I can say it was most likely a wolverine.I've been coast to coast and seen a lot of critters but never one like this one.So to see this article made want to post this commentary.I beleive it was off the RT 36 side.We were coming from Lafayette.


Thanks for the link to the photos, Aaron. Those are great shots, particularly in light of the elusiveness of wolverines.


Thanks for this encouraging report, Bob! A wolverine was also recently photographed near Mt. Adams, far south of their supposed range in the Cascades: http://seattletimes.nwsource.com/html/localnews/2009390936_skunkbear27m....


I'm impressed by the photographic evidence that remote camera picked up in the Cascades. Quite a menagerie! The yellow lab was almost as surprising as the wolverine.
