Autumn foraging dynamics of woodland caribou in experimentally manipulated habitats, northeastern Washington, USA
Article Abstract:
Caribou foraging in clearcuts with senescent fireweed as the predominant element have a lower dry-matter intake rate and diets with higher neutral detergent fibre than caribou diets in late winter. This research aimed to test the theories that there would be no differences in the foraging dynamics of tame woodland caribou between old-growth stands where the two main autumn forage items were removed and controls, and between old-growth stands and neighbouring clearcuts. It was found that snow had a more significant impact on caribou foraging dynamics in clearcuts where as little as 16 cm of show cut forage canopy cover by more than 90%.

Winter foraging ecology of woodland caribou in northeastern Washington
Article Abstract:
Woodland caribou in ecosystems in western North America are extremely dependent on lichens, as deep snow in this area makes it impossible for the caribou to feed on terrestrial forage. Recent research has used bottle-raised caribou in experimental arena trials with artificial trees and in field trials within historical late-winter habitat to investigate late winter foraging ecology of woodland caribou. It was found that the caribou focus on ridge areas, where there is the greatest concentration of arboreal lichen. Such forage is provided by standing snags of Engelmann spruce.
