A wilderness management-by-objectives planning system is outlined. Through identification of standards, acceptable wilderness conditions are defined and appropriate management actions formulated. A case example is provided.

Provides information on fire management policy, programs, and issues in parks, wildernesses, and other natural areas. In more than 100 papers, poster papers, and workshop summaries, both researchers and managers explore basic wilderness management philosophies, explain current wilderness, natural area, and fire management objectives, describe current natural fire programs, identify and discuss current fire management issues, present fire management planning considerations, describe operational techniques for park and wilderness fire management, and present results of current research...

Habitat types, community types and plant communities in the Rocky Mountains in which interior Pinus ponderosa, interior Pseudotsuga menziesii, interior Abies concolor, Picea pungens, Populus tremuloides, Pinus contorta, Picea engelmannii, and Abies lasiocarpa occur are tabulated. Included are the name, location, site, successional status, principal tree and understory associates, and the authority.

Old-growth spruce-fir stands on the Fraser Experimental Forest, Colorado, were found to be irregularly uneven-aged. Although subalpine fir trees were most numerous, most of the basal area was Engelmann spruce. Alternatives to current cutting methods are suggested for stands with similar structures.

Presents highlights of the forest resources of Montana as of 1980. Describes the forest resources, their extent, condition, and location, and discusses levels of some nontimber use of forest lands. Includes statistical tables: area by land -classes, ownership, growing stock and sawtimber volumes, growth, mortality, roundwood products output, utilization, and residues.

Passage of the Forest and Rangeland Renewable Resources Planning Act (P.L. 93-378) (RPA), as amended by the National Forest Management Act (P.L. 94-588), requires the U.S.D.A., Forest Service (FS) to develop and conduct periodic national assessments of renewable natural resources on forests and rangelands. Such assessments report the current and expected status of natural resources, and propose alternative opportunities with associated ecological, economic, and social impacts (Hoekstra et al. 1979). The appraisals of wildlife resources require the ability to forecast consequences of...

Scientific and historical literature was searched for documented accounts of early fires in the '"interior West" - Montana, Wyoming, Idaho, Utah, Nevada, and eastern Oregon. One hundred and forty-five accounts of fires by 44 observers were found. The majority of accounts described fires in progress. A smaller proportion referred to burned areas that were encountered; a few simply described regional fire occurrence based on the journalists' observations. Indians were identified as the primary ignition source over wide areas at lower and middle elevations. Some journalists noted that fire...

Provides guidelines for integrating practices for managing mountain pine beetle populations with silvicultural practices for enhancing multiple resource values of lodgepole pine forests. Summarizes published and unpublished technical information and recent research on the ecology of pest and host and presents visual and classification criteria for recognizing susceptibility status of lodgepole pine stands according to habitat types and successional roles of lodgepole pine. Reviews appropriate silvicultural systems and practices for commercial and noncommercial forest land designations and...

Aspen stands sprayed with herbicides had higher numbers of aspen suckers than adjacent unsprayed stands. Understory production was higher due to more grass production in the sprayed stands. While the composition of forb species was lower, the number of grass species was higher on sprayed stands than on unsprayed stands. Vegetative cover was greater on the sprayed plots, but organic matter was deeper on the unsprayed plots. These results agree with expectations of broadleaf herbicide treatments.

These proceedings include 105 papers and 12 poster presentations. Primary topics include: physical characteristics, hydrology, and ecology of riparian ecosystems; riparian resources; recreation, agriculture, wildlife, livestock use, fisheries, and amphibians and reptiles; multiple-use planning and management; legal and institutional needs; and riparian ecosystems in dryland zones of the world. A model Riparian Habitat Protection Statute is appended.
