The whooping crane is one of the most, if not the most, endangered birds in North America. A combination of hunting and habitat loss nearly drove the species to extinction in the 1940s. Thanks to the hard work of federal, state, and nongovernmental groups, there are now about 250 whooping cranes living in the wild and another 150 whoopers in captivity.  More »

    The Penland beardtongue (Penstemon penlandii), a showy perennial, is unique to Colorado. It is known only from only one site, which lies about 10 miles east of Kremmling, in Grand County. It is estimated the species occupies less than 1500 acres. The plant is threatened by development, off-highway vehicle recreation, oil and gas exploration, and livestock grazing.

    Pawnee montane skipper (Hesperia leonardus montana) is a rare butterfly that occurs only on the Pikes Peak Granite Formation in the South Platte River drainage system in Colorado, involving portions of Jefferson, Douglas, Teller, and Park Counties. Because of the limited habitat and range of the species, unexpected environmental, random events could have a major deleterious effect on the population.
