Breeding Birds In Uncut Aspen And 6- To 10-Year-Old Clearcuts In Southwestern Colorado, V.E. Scott, G.L. Crouch
Aspen Bibliography
Numbers of breeding birds were estimated for various sizes and ages of clearcuts, for edge habitat created by the clearcuts, leave strips between clearcuts, and uncut aspen forest (controls). Total numbers of birds were not different among three size classes or five age classes of clearcuts. Total were lower on clearcuts than on edges but not different from controls or leave strips.

Response Of Breeding Birds To Commercial Clearcutting Of Aspen In Southwestern Colorado [Usa], V.E. Scott, G.L. Crouch
Aspen Bibliography
Breeding birds on an aspen forest in southwestern Colorado increased in species diversity after 25% of the timber sale area forest was clearcut in patches of 3 to 20 acres. Bird population density on the forest with clearcuts was not significantly different from that on an uncut forest. Of the 20 species evaluated, six were more and one was less abundant than on the uncut forest.

Aspen Bibliography
Ruffed grouse habitat requirements and management opportunities have been defined by Bump et al. (1947), Grange (1948), Dorney (1959), Gullion at al. (1962), Moulton (1968), and Gullion (1972), among others. It is generally agreed that interspersion of cover types and age classes is one of the keys to better grouse populations.

Aspen Bibliography
Aspen forests provide important habitat for many species of wildlife (Gullion 1977b), especially in the West (see the appendix to this chapter). In the coniferous forests of the interior West, aspen groves may be the only source of abundant forage; in the grasslands they may be the sole source of cover. A primary value of the aspen ecosystem in the West during the past century has been production of forage for both wildlife and domestic livestock (see the FORAGE chapter).

The patterning of populations of plants and animals is probably the result of selection over time of organisms according to their individual physiological tolerances, behavioral adaptations to an environmental complex, and geographical availability (Gleason 1926).
