One thing we saw in Rocky Mountain National Park was elk.
Lots of elk.
Lots and lots of elk (click to view full size).
In fact, while at one point there were almost no elk left in this area – in 1913 and 1914 about fifty were transplanted from Yellowstone to repopulate them – today there seems to be a herd grazing in every meadow you pass. Because their natural predators, such as wolves and grizzly bears, have been extirpated from the park and its surroundings, their numbers have exploded dramatically. In order to protect sensitive riparian areas from overgrazing, the park has erected fences to create elk “exclosures” around some of the streams. They’ve also culled individuals periodically.
The park’s elk population is closely studied and monitored, and we spotted a couple with radio collars while we were there. One thing they keep close tabs on is the prevalence of Chronic Wasting Disease, a relative of “mad cow” disease that affects species in the deer family.
These weren’t the only large mammals we saw on our trip – we also spotted several moose, and from a distance a herd of mountain big-horned sheep. No black bears, but I should have plenty of chances to see those once I arrive in Wisconsin!
