Abstract
The gross area of the Black Hills of South Dakota and associated Bear Lodge Mountains of eastern Wyoming is about 3.5 million acres (1.4 million ha). Roughly half the area supports forest or woodland cover. Essentially pure stands of climax Rocky Mountain ponderosa pine (
Pinus ponderosa var.
scopulorum Engelm.) predominate on about 1.5 million acres (0.6 million ha). Scattered, smaller aggregations of similar ponderosa pine stands occupy about 250,000 acres (101 170 ha) of butte-top and scarp sites to the north and south of the Black Hills in Nebraska, Wyoming, and Montana (3, 8, 19).
