Introduction

The main objective of this study has been to obtain information on the seasonal movements and population ecology of woodland caribou (Rangifer tarandus caribou Gmelin) in the Wallace-Aikens lakes area of southeastern Manitoba. Information of this nature includes: seasonal changes in the centre of habitation for the herd; patterns of seasonal activity; changes in herd composition; population status of the herd; and factors affecting the population status. The relationship between the population status and the various environmental factors acting upon it is termed Population Ecology.

Active field work was conducted from May 1975 to April 1977, in an intensive study area (see Figure 1) consisting of approximately 950 km2. This area includes the region from the Broadleaf River east to Carroll Lake in Ontario and from Aikens Lake south to Wallace Lake. Stardom (1977) conducted a study on the winter ecology of woodland caribou in this area during the winters of 1970-1971 and 1971-1972.

This study represents research conducted by the author in accordance with requirements leading to the degree of Master of Science. Field activities were based at the University of Manitoba Taiga Biological Station situated at Wallace Lake. Field work was conducted under the supervision of Dr. W. O. Pruitt, Jr. Dept of Zoology, University of Manitoba.

This paper summarizes field activities from May 1975 to April 1977 and outlines the results and data analyzed to date. It therefore constitutes a final report in accordance with the terms of contract #510/77-82. The results and pertinent literature are discussed. Recommendations concerning the types of development associated with parks are given. A copy of the Master of Science thesis is to follow upon completion.
