An Analysis Of Howling Response Parameters Useful For Wolf Pack Censusing, Fred H. Harrington, L. David Mech

USGS Northern Prairie Wildlife Research Center

Gray wolves (Canis lupus) were studied from April 1972 through April 1974 in National Forest in northeastern Minnesota by radio-tracking and simulated howling. Based during 217 of 456 howling sessions, the following recommendations were derived for using howling as a census technique: (1) the best times of day are dusk and night; (2) July, August, and are the best months; (3) precipitation and winds greater than 12 km/hour should be avoided; (of 5 single howls should be used, alternating "flat" and "breaking" howls; (5) trials should 3 times at about 2-minute intervals with the first trial at lower …

Bureaucracy And Wildlife: A Historical Overview, Edward E. Langenau

International Journal for the Study of Animal Problems

This paper provides a framework for understanding the Government's position on many wildlife topics, including humane ethics. The Government's historical role in wildlife conservation is traced to pertinent theories of bureaucracy. It is shown that Government involvement in wildlife conservation increased through successive stages of change because of interest group activity.

Ethical Issues And Future Directions In Wildlife Management, John W. Grandy

International Journal for the Study of Animal Problems

Recent progress in the protection of wildlife and wildlife refuges is currently being undermined by the efforts of James Watt, U.S. Secretary of the Interior, who believes that commercial interests should take precedence over the preservation of pristine wilderness areas and wildlife sanctuaries. As populations approach extinction because of programs like decimation of habitats and predator control, the consequent loss is more than simply aesthetic: genetic material unique to each species will be lost forever. Particular issues of immediate concern are the fate of bobcats and whales, inhumane trapping, and the Endangered Species Act. As a longer-term concern, wildlife management's …

Introduced Species And The Issue Of Animal Welfare, Michael Hutchins, Victoria Stevens, Natasha Atkins

Ecology Collection

Recently, considerable debate has been heard about the control or elimination of introduced or "exotic" animals on publicly held U.S. lands. Species introductions, whether intentional or unintentional, seem to be an inevitable result of human activities, but they may result in both economic and ecological problems: It has been estimated that over 90 percent of all such introductions have been harmful in some respect. Control of exotics can be accomplished through containment, shooting, poisoning, reintroduction of native predators, introduction of disease organisms, live capture and removal, and reproductive inhibition.

Those who must make decisions about the fate of introduced species …
