Park Pasture Aspen Exclosure
Plate 355X. Park Pasture Aspen Exclosure 1958 - 2003 Viewed north along the western edge of the Park Pasture aspen exclosure on Boulder Mountain’s eastern flank - - see Plates 7x and 8x. When this exclosure was established by the Forest Service in 1957, it was on a joint-use allotment that was heavily grazed by domestic sheep, cattle, and mule deer, which limited aspen regeneration (Kay and Bartos 2000). With protection from livestock, however, aspen successfully regenerated inside the exclosure, without fire or any other disturbance. Aspen regenerated outside the exclosure, though, only when mule deer numbers declined during the early 1970s (Kay and Bartos 2000). Willows in the meadow appear largely unchanged except where overtopped by spruce. Conifers have increased on the distant hillside and a few ponderosa pine have become established inside and outside the exclosure. Aspen inside the exclosure has not regenerated in recent years due to repeated browsing of aspen suckers by elk and mule deer (Kay and Bartos 2000). The area had not been grazed by cattle in 2003 when the site was revisited, but elk and deer sign was abundant.
