Available in PDF, EPUB and Kindle. Book excerpt: "The primary objective of this study was to define and identify critical caribou habitat in northern Yukon (ie. north of treeline) in order to better predict impact of any human activity on caribou. A comprehensive ecological approach was used to first of all define "critical" habitat. Caribou movement and behavior was related to the "need to feed" and the "need to avoid insects". 1. Historical and recent movements and distribution of the herd pointed to the importance of the Richardson Mountains and the Muskeg Basin regions of the northern Yukon during summer insect season. Radio-tracking relocations pointed to the frequent fracturing and reformation of large aggregations during the insect season and the constant movement of these groups. 2. Our assessment of the regional distribution of vegetation communities has shown that the Blow River valley and the valleys of the Richardson Mountains support lush vegetation. ...3. Our study of mosquito activity ... showed that mosquito activity peaks the second week of July and declines thereafter, .... 4. Our documentation of regional weather in 1986 revealed the regional influence of warm, moist northeasterly flows from interior Alaska and the cool southwesterly flows from the Beaufort Sea. Our study appeared to lie within the area of conflict between these two systems, resulting in dynamic weather patterns that can and are exploited by the caribou. ... 5. Our study of caribou behaviour response to insect harassment revealed the importance of defense strategies such as forming large dense groups when insects are active, and the advantage gained by individuals in the core or windward side of a group. 6. Caribou activity budgets indicated that insect harassment had the most profound effect of reducing lying and feeding at the expense of standing. ... The study provides the baseline information on the use of the region by the Porcupine caribou herd during the summer period, and combined with our knowedge of caribou/human interactions from related studies, puts us in an excellent position to help guide industrial development. ...

Available in PDF, EPUB and Kindle. Book excerpt: "This report briefly summarizes the results of the third summer field season, designed to provide baseline information for the potential development of Beaufort Sea oil and gas reserves. In the initial two field seasons, research focussed on documenting the distribution, movement patterns and habitat selection of the herd during insect season. As well, the role of insect harassment in influencing activity patterns and overt behaviour was documented in detail. In this third field season our objectives were to document the biophysical factors that influenced the patterns observed in the previous field seasons. Our objective was to construct a vegetation map for the study area using classification system that was particularly meaningful for caribou. In addition, we documented regional weather patterns, in an attempt to relate regional patterns to potential insect harassment levels. We also documented caribou movement and distribution in July and early August"--Leaf 2.
