The taruca (Hippocamelus antisensis) is the only deer species found permanently in rugged mountainous habitat above the tree line. I studied the social organization of this deer in relation to its reproductive cycle and habitat use in the high Andes of southern Peru. Tarucas bred seasonally. Most fawns were observed towards the end of the rainy season between February and April. Mating was most common in June, during the dry season, and antler-shedding in males occurred in September/October, at the onset of the rainy season. The deer lived in social groups and, unlike most seasonally breeding cervids, formed large mixed-sex groups nearly all year. During the birth season, however, all pregnant females segregated to form female associations. At this time, adult males were found equally in mixed-sex groups or in small all-male groups. These groups differed in their habitat use. Female groups used areas of higher elevation, steeper slopes, and greater rock-cover than either male or mixed-sex groups. I suggest that selection of more rugged and concealed habitats by lactating females is primarily an antipredator strategy to reduce risk of predation on fawns. Tarucas are compared with other social Cervidae and with their ecological counterpart: the mountain Caprinae. The social structure of Hippocamelus resembles that of wild goats (Capra spp) and other Caprinae of similar ecology but it differs from that of wild sheep (Ovis spp). / Science, Faculty of / Zoology, Department of / Graduate

An important segment of outdoor recreational activity in eastern Oregon is based on the harvest of deer. The deer population can be altered in two ways. Rangeland, which provides feed and cover for deer, can be improved through public or private investments or hunting regulations can be changed. This study dealt with the economic impact that changes in deer population through changes in range forage and/or deer hunting regulations might have upon a rural community. A computer simulation model of important components and interactions of the bio-economic system was developed. The biological components consist of a deer population, a cattle population, and a range resource. The economic component consists of economic activities within a rural community. It is based on an input-output model with trading patterns among sectors assumed to remain relatively constant. The model can be characterized as a density dependent system with deer and cattle interrelated through the use of available forage. The model can be used for a comparison of two different sets of natural resource management strategies. A set of natural resource management strategies consists of deer hunting patterns, cattle sales patterns, and expected range forage production. The benefits and/or costs resulting from this comparison are divided into rancher benefits, resident benefits, and hunter benefits. Resident benefits are separated into resident income and local government revenue. Experiments using the model indicated that the amount and distribution of benefits from changes in range forage availability were dependent upon the relative levels of production in each of the range forage categories. Deer hunting regulations also affected the amount and distribution of benefits. For the alternatives considered, hunter benefits were affected most and rancher income was affected least by changes in range forage production. Conclusions from the study indicated that information on forage availability as well as the relationship between the use of a range area by either deer or cattle and forage availability would substantially increase accuracy in measurement of the magnitude and distribution of benefits and costs to a community from changes in natural resource management strategies. / Graduation date: 1974

The response of the Winnipeg deer herd to increased land development was assessed. This included analysis of habitat loss, optimal population size, supplementary feeding, and deer related damage. Management techniques used in other North American cities were documented. There is 3490 ha of potentially manageable habitat within the study area, 2242 ha of which lie within the Perimeter Highway. Through Plan Winnipeg policy provides for development of 737 ha, or 33% of deer wintering habitat within the Perimeter by the year 2001, only 103 ha are expected to be lost. This is comprised of 87 ha of residentially zoned land and 16 ha of industrial land. The remaining 634 ha is zoned for industrial use. Tripling of the Winnipeg deer population since 1975 has resulted in an increase of deer depredation and deer vehicle accidents. If deer are to be maintained as a beneficial resource, a long term management plan needs to be developed for the Winnipeg herd. To assure that urban values are reflected in such a plan, public input is essential. From this information it may be possible to design a sociological carrying capacity for the deer herd specific to Winnipeg's situation. Habitat maintenance via leases or grants, regulation of deer numbers through continuation of the relocation program, and intercept feeding programs on manageable habitat, are recommended. To insure that individual residents do not bear the entire impacts of the deer population, damage prevention and compensation programs need to be implemented.
