The answer to the question: Which animals sometimes wander into Bryce Canyon? is inside the article: More than 400 native plant species live in the park. There are three life zones in the park based on elevation: The lowest areas of the park are dominated by dwarf forests of pinyon pine and juniper with manzanita, serviceberry, and antelope bitterbrush in between. Aspen, cottonwood, water birch, and willow grow along streams. Ponderosa pine forests cover the mid-elevations with blue spruce and Douglas fir in water-rich areas and manzanita and bitterbrush as underbrush. Douglas fir and white fir, along with aspen and Engelmann spruce, make up the forests on the Paunsaugunt Plateau. The harshest areas have limber pine and ancient Great Basin bristlecone pine, some more than 1,600 years old, holding on.The forests and meadows of Bryce Canyon provide the habitat to support diverse animal life including foxes, badgers, porcupines, elk, black bears, bobcats, and woodpeckers. Mule deer are the most common large mammals in the park. Elk and pronghorn, which have been reintroduced nearby, sometimes venture into the park. Bryce Canyon National Park forms part of the habitat of three wildlife species that are listed under the Endangered Species Act: the Utah prairie dog, the California condor, and the southwestern willow flycatcher. The Utah prairie dog is a threatened species that was reintroduced to the park for conservation, and the largest protected population is found within the park's boundaries.About 170 species of birds visit the park each year, including swifts and swallows. Most species migrate to warmer regions in winter, although jays, ravens, nuthatches, eagles, and owls stay. In winter, the mule deer, cougars, and coyotes migrate to lower elevations. Ground squirrels and marmots pass the winter in hibernation.Eleven species of reptiles and four species of amphibians have been found in the park. Reptiles include the Great Basin rattlesnake, short-horned lizard, side-blotched lizard, striped whipsnake, and the tiger salamander.Also in the park are the black, lumpy, very slow-growing colonies of..., can you guess it ?
