Plants and Wildlife in Rocky Mountain
Volcanic uplifts and the savage clawing of receding glaciers created Rocky Mountain's majestic landscape. You'll find four distinct ecosystems here—a riparian (wetland) environment with 150 lakes and 450 miles of streams; verdant montane valleys teeming with proud ponderosa pines and lush grasses; higher and colder subalpine mountains with wind-whipped trees (krummholz) that grow at right angles; and harsh, unforgiving alpine tundra with dollhouse-size versions of familiar plants and wildflowers. Alpine tundra is seldom found outside the Arctic, yet it makes up one-third of the park's terrain. Few plants can survive at this elevation of 11,000–11,500 feet, but many beautiful wildflowers—including alpine forget-me-nots—bloom here briefly in late June or early July.
The park has so much wildlife that you can often enjoy prime viewing from the seat of your car. Fall, when many animals begin moving down from higher elevations, is an excellent time to spot some of the park's animal residents. This is also when you'll hear the male elk bugle mating calls (popular spots to see and hear bugling elk are Kawuneeche Valley, Horseshoe Park, Moraine Park, and Upper Beaver Meadows).
May through mid-October is the best time to see the bighorn sheep that congregate in the Horseshoe Park/Sheep Lakes area, just past the Fall River entrance. If you want to glimpse a moose, try Kawuneeche Valley. Other animals in the park include mule deer, squirrels, chipmunks, pikas, beavers, and marmots. Common birds include broad-tailed and rufous hummingbirds, peregrine falcons, woodpeckers, mountain bluebirds, and Clark's nutcracker, as well as the white-tailed ptarmigan, which live year-round on the alpine tundra.
Mountain lions, black bears, and bobcats also inhabit the park but are rarely seen by visitors. Altogether, the park is home to roughly 60 species of mammals and 280 bird species.
