A timberline stand of Libocedrus bidwillii subalpine low forest at Pegleg Flat, Arthur's Pass, was partly destroyed by fire in the late 19th century. Patches of surviving low forest contain very few Libocedrus seedlings and lack young trees of 5-15 cm d.b.h. Only 14 large seedlings and saplings were located in the postfire sere in the formerly burnt areas. The small numbers of seedlings on both...

Tamias umbrinus Allen, 1890, a medium-sized chipmunk commonly called the Uinta chipmunk, is 1 of about 25 species of extant chipmunks. It is distributed in the western United States from southern Montana south to Arizona and from Colorado west to eastern California. T. umbrinus prefers montane and subalpine coniferous forest at elevations between 1,417 and 3,660 m. The species is listed as ‘‘Le...

Species in a Colorado subalpine ecosystem show subtle interdependences. Red-naped sapsuckers play two distinct keystone roles. They excavate nest cavities in fungus-infected aspens that are required as nest sites by two species of swallows, and they drill sap wells into willows that provide abundant nourishment for themselves, hummingbirds, orange-crowned warblers, chipmunks, and an array of ot...
