Ecology of the Porcupine caribou herd
Researchers have described general patterns of population regulation that fit most caribou (Rangifer tarandus) herds. Nevertheless, specific factors operating on particular populations vary greatly, and efforts to categorize herds according to the general patterns often lead to confusion. It is difficult for biologists to attempt to describe population dynamics in terms of density relationships...
متن کاملVariations in plant forage quality in the range of the Porcupine caribou herd 1
Understanding potential impacts of vegetation change on caribou energetics requires information on varia¬ tions in forage quality among different plant types and over time. We synthesized data on forage quality (nitrogen, neutral detergent fiber and dry matter digestibility) for 10 plant growth forms from existing scientific literature and from field research in the Arctic National Wildlife Ref...
متن کاملSeasonal movements of satellite-collared caribou from the Bathurst herd
SUMMARY We tracked the movements of between six and 19 caribou cows from the Bathurst herd from April 1996 to December 2000 using collars that transmit to a satellite. Spring migration routes partially depended where the caribou wintered which changed from northwest of Great Slave Lake to southeast of Great Slave Lake in winter 1997/98 and 2000/01. In winters of 1998/99 and1999/2000, distributi...
متن کاملThe Flux of Trust: Caribou Co-Management in Northern Canada
There is a presumption that the primary goal of creating alternative resource management systems is to increase the efficiency of the management decisions made. However, changing the rules of resource management leads to institutional uncertainty, and such instability is an integral part of developing alternative management systems. In the case of barren ground caribou management, these rule ch...
متن کاملThe role of wildland fire in caribou ecology
Objective 2: Improve, maintain or enhance habitat diversity by managing naturally ignited wildfire. a. Complete vegetation mapping of the Buckland Valley Wildlife Habitat Area (WHA), that was initiated during Fiscal Year (FY) 82, by end of FY84. Rationale: At this time, the land cover on that portion of the WHA west of the Tagagawik River has been mapped from 1:60,000 scale color IR photos and ...
