The exclosure was erected in 1983 for wildlife habitat protection (sage grouse). A portion of Station Spring (within the exclosure) has been capped and piped to a cattle water trough, where it then flows back through the exclosure. There is an internal fence within the exclosure; the purpose of the fence is unclear. Gentle, wide headwaters basin with numerous seeps and very slow drainage through the exclosure. All channels are thoroughly vegetated with graminoid communities of varying degrees of moisture tolerance; there are no unvegetated channels. The drier valley bottom terraces have Artemisia cana dominated communities. Vegetation patterning is a small-scale mosaic with evidence of past disturbance from cattle grazing. The exclosure lies in a rolling volcanic upland dominated by Artemisia tridentata vaseyana, Juniperus occidentalis, and Cercocarpus ledifolius.
