Genetic variation among 83 populations of Pinus contorta from the Northern Rocky Mountains of the United States was studied with 7-year-old trees planted in three contrasting environments. Analyses of nine traits reflected adaptation to biotic and...
Vegetation classification -- Oregon -- Eagle Cap Wilderness.
Describes plant communities in two drainages of the Eagle Cap Wilderness, Wallowa Mountains, Oreg. Compositional data and implications for wilderness management are provided for 14 coniferous forest types and nine other community types. Four...

The Columbia River Basin Succession Model (CRBSUM) simulates broad-scale landscape changes as a consequence of various land management policies. CRBSUM is a coarse-scale, spatially explicit, deterministic model with stochastic properties that...
Water regime, chemical features, temperature factors, light penetration, substrate properties, and physical characteristics are described for Northern Great Plains strip mine ponds and stockdams, followed by a discussion of how their interaction...

Ground sample data were collected for a land cover database and raster map that portray 159 vegetation classes at 1 km² resolution for the conterminous United States. Location for 3,500 1 km² ground sample plots were selected randomly across the...
This report describes the current status of 67 threatened, endangered, and vulnerable wildlife species in the Rocky Mountain Region. Known or potential reasons for population declines and species susceptibility are identified; and distributions,...
Boothill above Virginia City, Montana. Plate 67a ( 1924) Sagebrush/Grass Fire Group. Elevation 5800 ft (1768 m). The camera faces north from Boothill above Virginia City, Montana. Graves are those of five members of Henry Plummer's infamous road...
Boothill above Virginia City, Montana. Plate 67b (July 9, 1980) 56 years later. Grading and remonumenting graves resulted in displacement of soil in foreground. Note change in location of grave markers. Near slope shows a marked increase in the...
