Book excerpt: The occurrence of lungworms of the genus Protostrongylus in bighorn sheep (Ovis c. canadensis') has been known since the 1920's but the complex system which involves lungworms, bighorn sheep, and the environ ment remains poorly understood. The purpose of this study was to investigate the role of nutrition and other environmental factors in lungworm infections. Two neighbor ing bighorn sheep herds in the mountains of west-central Alberta were studied from September 1972 to May 1974. Seasonal variation in the rate of lungworm larvae shedding in the feces of two bighorn sheep herds was documented. Two distinct periods of shedding were apparent. These were approximately coincident with summer and winter, summer being a period of low larval shedding and winter a period of a higher rate of shedding. The possibility that this phenomenon could be the result of dilution or concentration of larvae in a seasonally variable fecal mass was discussed. Seasonal variation in the qualitative nutrition of the two sheep herds was evaluated using fecal nitrogen as an index for the estimation of forage crude protein, digestibility and gross energy content. Fecal protein (N X 6.25) proved to be a useful tool for the purposes of this study. Simulated energy positions of both sheep herds for both winter periods of the study were compared using a bioenergetics model construc ted with values from domestic and wild ruminant literature. The resulting observation was that although the energy position of both sheep herds declined from one winter to the next, lungworm burdens, as evaluated by larvae counts, fell significantly. The relevance of nutrition in the etiology of heavy lungworm infections was discussed. The observed decline in the intensity of lungworm infections followed a 30 percent decrease in rainfall from one preceding spring-summer season to the next, thus implicating ecological and/or environmental factors other than nutrition in the etiology of changing lungworm burdens. Prenatal infection of four near term bighorn sheep with first- and third-stage lungworm larvae was demonstrated. This finding suggested a more cosmopolitan occurrence of the phenomenon in bighorn sheep than was previously suspected.

Book excerpt: Seven bighorn sheep were captured and equipped with telemetry collars, Two hundred and six relocations of radiocollared sheep provided information on seasonal distribution and movements, key use areas, home range size, habitat selection and population dynamics. The sheep population, estimated at fewer than 25 animals, was found to be a contiguous herd which made recurrent use of specific key areas throughout the range. Ural-Tweed bighorns were consistent in their use of exposed oversteepened terrain along the east escarpment of Lake Koocanusa, Five habitat types, received 100 percent of the sheep use annually, based on telemetry relocations, Grassy openings andd open forest cover types characterized sites selected by sheep during most seasons of the year. Rough fescue was found to be an important dietary constituent throughout the year, while browse, as a forage class, was important during periods of heavy-crusted snow conditions and also during spring flowering. Endoparasite loads were low, but the possibility of a population crash due to the lungworm-pneumonia complex during the 1960's is discussed. Thirty-five hundred acres of bighorn sheep habitat lost to Libby Dam Project and degeneration of residual habitat due to ecological succession in the absence of natural fires continues to reduce the carrying capacity of the range. Natural as well as human-caused decimating factors are discussed in relation to their overall influence on the sheep population. Recommendations for management of the Ural-Tweed sheep herd and its habitat are forwarded.
