Birds were censused in six communities within a lodgepole pine (Pinus contorta) forest in the Uinta Mountains of Utah: wet and dry meadows, mature and stagnated lodgepole pine stands, and openings made by clearcutting in 1940 and 1960 and presently having regenerating lodgepole pine stands. The richest avifauna was in the dry meadows, a finding that suggests the need to protect these areas from disturbance. Although a few bird species were adversely affected by clearcutting, many were more numerous in the clearcut areas than in unlogged stands, and the number of species remained about the same. Disturbance of the stagnated stands would be highly beneficial to birds.

黑松林内六个群落的鸟类

对犹他州尤因塔山脉的黑松 (Pinus contorta) 森林内的六个群落进行了鸟类普查：潮湿和干燥的草地、成熟和停滞的黑松林，以及 1940 年和 1960 年因砍伐而形成的空地，目前有再生的黑松林。最丰富的鸟类区系位于干燥的草地上，这一发现表明需要保护这些地区免受干扰。尽管少数鸟类受到砍伐的不利影响，但砍伐地区的许多鸟类数量比未砍伐的地区要多，而且物种数量基本保持不变。停滞的林分的干扰对鸟类非常有益。
