Maps for wildland resource inventory and managament purposes typically show vegetation types, soils, and other areal information. For field work, maps must be large-scale. For safekeeping and compact storage, however, they can be reduced onto film, ready to be enlarged on demand by office viewers.…

Bush penstemon (Penstemon fruticosus (Pursh) Greene), an attractive ground cover on east Cascade slopes, appears to survive under low fertility, xeric conditions. These plant characteristics are desirable for revegetating severely disturbed areas. Seedling response to fertilization was…

The Priest River Experiment Station was established in 1911 as the center for forest research in the productive forests of northern Idaho, western Montana, and northeastern Washington. Located out in the forest of northern Idaho, 15 miles from the nearest small town, it was to be the hub of forest…

Panels of judges have been evaluating the esthetic dimension of harvested areas in the Northern Rockies. Studies conducted in Wyoming and Montana agree with intuition in that forest scenes are generally liked less as the evidence of man's activities increases.
