Grizzly Bears and Resource-Extraction Industries: Effects of Roads on Behaviour, Habitat Use and Demography
Mclellan BN and Shackleton DM. 1988. Grizzly Bears and Resource-Extraction Industries: Effects of Roads on Behaviour, Habitat Use and Demography. Journal of Applied Ecology. 25(2):451-460
This article presents data on the displacement of grizzly bears from habitats by roads developed for resource-extraction industries (forestry, mining, gas and oil). A basic null hypothesis is tested that grizzly bears use areas adjacent to roads as often as they use areas away from them. Discussion of the effects of age-sex class, reproductive status, habitat type, amount of vehicular traffic and time of day on this pattern of use, and the demographic implications are explored.
