Ecology Of The Morgan Creek And East Fork Of The Salmon River Bighorn Sheep Herds And Management Of Bighorn Sheep In Idaho, James K. Morgan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An ecological study on the Morgan Creek and the East Fork of the Salmon River, Idaho, Bighorn Sheep herds was conducted from July 1, 1966 to February 28, 1970.

The Morgan Creek population numbered about 100 animals upon termination of the study. The trend of this population was downward. The East Fork population numbered about 50 animals and the trend appeared to be stable or slightly downward.

Productivity of both herds was low. Lamb mortality was high and recruitment to the breeding herd low. Low recruitment rates coupled with hunting pressure caused a decline in the ram component of both …

The Effects Of Available Water Upon Populations Of Chukar Partridge On Desert Mountains Of Utah, William W. Shaw

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The importance of surface water to chukar partridges (Alectoris graeca) and the feasibility of rain-catchment devices for improving chukar habitat were studied on the Thomas and Dugway Mountain Ranges in western Utah during 1969 and 1970.

Sources of surface water were removed from one mountain range, and chukar populations on that range were compared with populations on an adjacent range with permanent sources of water.

Providing drinking water did not improve chukar productivity, survival, or availability to hunters. Although most birds concentrated around water supplies in the summer, some chukars appeared to live completely independent of any permanent …

The Coalville Deer Herd In Northeastern Utah: Its Ecology And Management, Gary L. Hickman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary objective of this study on the Coalville Deer Management Unit adjacent to the corner of Wyoming in Utah was to determine the condition of the deer herd in relation to its range and population characteristics.

Postseason doe-fawn ratio was 100:77, while an adjusted doe-fawn ratio accounting for the unproductive female yearling segment was 100:105. The approximate net-productivity for 1964 was 44 percent compared to 27 percent in 1965. In 1964-65, the average age-class mortality rate for the male and female segments was 45 and 35 percent respectively. Preseason and postseason sex ratios were 64:100 and 60:100 respectively.

Pheasant Raising, P Smetana

Journal of the Department of Agriculture, Western Australia, Series 4

THERE has been increased interest in pheasant raising in Western Australia over the past few years, mainly as a result of more sophisticated eating habits and the associated restaurant boom, as well as farmers in country areas looking for more profitable sidelines.
