Consider the following question:
"A proposed development activity that promises substantial economic benefits will have significant adverse impacts on fish and wildlife resources in the area. What percentage of all your agency wildlife and fisheries professionals could develop and present a fully professional defense for the faunal interests in the area to an audience largely oriented towards commodity development?"
Before you become too uneasy with your answer to that question, let me pose another:
"Your wildlife and fish budget request to carry out a proposed program, regulatory activity, project or operation has been challenged. What percentage of all your agency …

In recent years, a rapidly expanding body of research has made wildlife biologists and land managers increasingly aware that old-growth forests are critical wildlife habitat. This has come at a time when old-growth forests are rapidly being eliminated in order to meet human demands for wood products. In Oregon, for example, it is anticipated that virtually all remaining old-growth forests on commercial forest lands will be harvested by the year 2020 (Beuter et al. 1976). Thereafter, regenerating forests on cutover areas will be intensively managed and harvested every 60-80 years on most sites. If history is a good example, it …
Livestock And Riparian-Fishery Interactions: What Are The Facts?, William S. Platts
Livestock And Riparian-Fishery Interactions: What Are The Facts?, William S. Platts
USDA Forest Service / UNL Faculty Publications
The riparian environment has become a key consideration in the planning and management of the public lands. This highly productive habitat receives many uses, some of which conflict with one another. Because there are conflicts that need immediate attention, range and fishery managers are making complicated, hurried decisions, often without the benefit of adequate knowledge or experience. In addition, interpretations emerging from riparian studies are often confusing and contradictory, inhibiting the manager's decision-making abilities.
Leopold (1974) stated that fish and wildlife habitat in western rangeland has experienced and is experiencing a steady deterioration under livestock grazing. The same year, Heady …

It has been a little more than a year since President Reagan was inaugurated, and a little less time than that since I was confirmed and sworn in as assistant secretary of agriculture. We have moved to establish and implement some changed emphases in our resource management programs. So, by now there should be little mistake about our intent to improve natural resource management on the national forests. We intend to increase the productivity of these resources without corresponding increases in federal appropriations. We intend to generate increased receipts to the U.S. Treasury by emphasizing revenue-producing activities such as timber …
Solving The Habitat Dispersion Problem In Forest Planning, Stephen P. Mealey, James F. Lipscomb, K. Norman Johnson

The National Forest Management Act (NFMA) of 1976 (16 U .S.c. 1600) requires that each National Forest, by 1985, prepare one integrated management plan that provides for multiple use and sustained yield for goods and services (36 CFR 219). Such plans must, by inference, emphasize single resources only to the extent that thresholds or minimum legal conditions for all other resources are always provided (Clawson 1975). The goal for wildlife to be met by each forest plan is: manage wildlife habitats to maintain viable populations of all existing native vertebrate species in the planning area (the forest) and maintain and …
Habitat Classification-Assessments For Wildlife And Fish, Hal Salwasser, William B. Krohn
Habitat Classification-Assessments For Wildlife And Fish, Hal Salwasser, William B. Krohn
USDA Forest Service / UNL Faculty Publications
Comprehensive planning and management of natural resources require the assessment of existing and future conditions offish and wildlife. Fish and wildlife, hereafter referred to as wildlife resources, can be inventoried and assessed either in terms of animals or habitats. Both approaches are useful given certain management objectives. For example, population inventories in concert with other data, are often used to assess the impacts of hunting. In contrast, habitat inventories are used to evaluate the impacts of grazing, or other land and water uses, on wildlife resources. Our objective is not to compare or contrast the two approaches, but to focus …

Wildlife and Fish Habitat Relationships (WFHR) is a Forest Service system for integrating wildlife and fish information and assessment data into interdisciplinary land and resource management. WFHR is a comprehensive organization of information in a format useful for managing wildlife through the management of their habitats. The WFHR System assists the Forest Service in meeting its goal of managing wildlife and fish habitats, both for species diversity as well as for individual species of management concern.
The Rocky Mountain WFHR System (USDA Forest Service 1981a) organizes information on 853 vertebrate animal species occurring on National Forest System lands in the …

Riparian microhabitats in coniferous forests in northeastern Oregon are sensitive to alteration. They have been used disproportionately by people, livestock, and wildlife. These uses have altered the habitats, specifically by reducing vegetative structure (Thomas 1979).
Land management agencies are revegetating depleted riparian zones to improve fish and wildlife habitat. Managers need information on the response of birds to kinds and structures of vegetation so that wildlife objectives can be met.
Several studies have dealt with the relationships of riparian vegetation and avifauna (Carothers and Johnson 1975, Ferguson et al. 1976, Stauffer 1978). Although these studies determined some of the habitat …
Needs For And Approaches To Wildlife Habitat Assessment, Jack Ward Thomas
Needs For And Approaches To Wildlife Habitat Assessment, Jack Ward Thomas
USDA Forest Service / UNL Faculty Publications
For many years prior to 1969, wildlife was essentially defined, in the practice of governmental bodies, as those species hunted for sport, trapped for furs, controlled to accomplish human objectives, or of particular aesthetic value. Governmental management of these species was based on funding obtained from or supported largely by clearly identified constituencies.
Universities evolved specialized programs in wildlife biology and management to produce the knowledge and trained professionals to meet these needs. Many such programs were oriented to training in zoology which emphasized the animal and populations while paying less attention to habitat.
As a result, most wildlife research …
