Albertas Grizzly Bear Rec everywherey Action Plan
The placement of the grizzly bear populations in Alberta assume fluctuated greatly in this century with changes in the perceived classification of grizzlies as a predator to its official designation as fur-be ber in 1928. The keep down estimated bear population in Alberta in 2000 was 841 and another, relatively broken census in 2006 estimates the current population at roughly 175-185 bears (www.srd.gov.ab.ca). This dramatic decline in the population of grizzlies in Alberta over the last few years is a result of the frenzied boom in the oil and gas industry and totally of the resultant development therein. Particularly, the density of road systems has greatly change magnitude to allow for easier access to resource extraction sites in the more(prenominal) remote areas of the province. In large carnivore studies throughout the world, roads have been implicated in reducing habitat quality cod to noise, human avoidance, and fragmentation (Dyer et al., 2001). As a result, humans and bears are coming into contact with one another with increasing frequence as we expand our encroachment on its habitats.
Bears are by nature very resilient and disease resistant; it has no graphic enemies except man and the vast majority of deaths over the outgoing decade are a result of human action mechanism: illegal kills, self-defence kills, and road accidents. Many areas of Alberta provide springy habitat for grizzly bears (Ursus arctos L.) and other wildlife, it is an appropriate region for misgiving the interaction between disturbance and wildlife habitat use (Nielsen et al., 2006). In disturbed areas, mortality risk increases due to a high likelihood of conflict between bears and humans. Anthropogenic habitat disturbances demand bears directly by increasing their vulnerability to legal, or illegal, hunt by humans; and indirectly changing the availability of food, and impacting reproductive memory and mortality rates. To enhance conservation efforts it may be advantageous to...If you want to get a full essay, order it on our website: Ordercustompaper.com
