The National Wildlife Refuge System in the United States includes about 150 million acres of lands and waters within 550 refuges managed for conservation. A variety of laws, regulations, and management polices help ensure these areas will be preserved for future generations. In a web-based survey, 35 refuges reported having established populations of moose (A ices alces) within their boundaries with nearly 40 million acres of moose habitat, 99% in Alaska. The 4 recognized sub-species of moose in North America were represented on refuges found in 12 states. Approximately 39,000 moose were reported inhabiting refuges in the USA; about 38,000 in Alaska. Only 9 refuges used management practices specifically to benefit...
The Chisana caribou herd (CCH) is a small international herd occurring in Yukon and Alaska on the Klutlan Plateau and near the headwaters of the White River. During the 1990s through 2003, the herd experienced a long and steady decline in population. Low recruitment, predation, climate, habitat, and harvest pressure likely all contributed to the decline. From 2003 to 2006, a recovery effort designed to increase recruitment and calf survival was conducted. Pregnant cows were captured and enclosed within a holding pen during the last weeks of gestation and a few weeks following calving. During recovery planning and upon the completion of the program, the need for a management plan was stressed by the recovery team....
Contradictory management objectives in adjacent jurisdictions can affect transboundary wolves and their associated socio-ecological systems. Elite interviews and case study methodology were used in this thesis to explore three transboundary wolf management agreements, their effectiveness, and their impacts on wolves, ecosystems and stakeholders. Separate agreements between the State of Alaska and: Yukon-Charley Rivers National Preserve, and Denali National Park and Preserve, and an agreement between Italy and Switzerland show that despite a diversity of socio-ecological contexts, approaches, and hierarchical level of actors, transboundary wolf agreements are prone to ephemerality. The ephemerality of these agreements...
Systematic conservation plans have only recently considered the dynamic nature of ecosystems. Methods have been developed to incorporate climate change, population dynamics, and uncertainty in reserve design, but few studies have examined how to account for natural disturbance. Considering natural disturbance in reserve design may be especially important for the world's remaining intact areas, which still experience active natural disturbance regimes. We developed a spatially explicit, dynamic simulation model, CONSERV, which simulates patch dynamics and fire, and used it to evaluate the efficacy of hypothetical reserve networks in northern Canada. We designed six networks based on conventional reserve design methods,...
The NRC report reached 17 conclusions and associated recommendations, most of which urged that predator management efforts have a more cautious, research-based, conservative, experimental, and adaptive approach that included public involvement and economic evaluations (NRC 1997). MANAGEMENT IMPLICATIONS Because predator reduction in Alaska has been mandated by a state statute since 1994, ADFG biologists who may be concerned about the widespread nature of efforts to reduce grizzly bear abundance have limited ability to change management direction or emphasis.

The original Management Plan for the Wilderness Preserve and Habitat Protection Area was approved in 2004 by the Vuntut Gwitchin First Nation, North Yukon Renewable Resources Council, and Yukon Government. This updated version of the plan was reviewed, edited and approved by the members of the Committee of Management Agencies, with representatives from Vuntut Gwitchin Government, North Yukon Renewable Resources Council, Yukon Government and Fisheries and Oceans Canada. The content of the plan has been updated, but no substantive changes were made during this review. A full review of the management plan will occur after five seasons of commercial bear viewing operations. As of September 2010, three seasons of operation...
We studied kill rates by wolves (Canis lupus) on a rapidly growing moose population in the east-central Yukon. We added these data to the cumulative functional response curve obtained in other North American wolf studies. Our kill rates are higher than those predicted at low moose densities. The kill rate increases rapidly, reaching 2.4 moose per wolf per 100 days at 0.26 moose/km2 and remains constant at this level. No data are available below 0.2 moose/km2 to indicate the shape of the ascending curve. Based on moose distribution and the low prey-switching ability of wolves, we suggest that the functional response curve is of type II. Our wolf predation rate model predicts that moose are held to a low density equilibrium...

We studied the kill rate by wolves (Canis lupus) after a large-scale wolf removal when populations of wolves, moose (Alces alces), and woodland caribou (Rangifer tarandus caribou) were all increasing. We followed a total of 21 wolf packs for 4 winters, measuring prey selection, kill rates, and ecological factors that could influence killing behavior. Wolf predation was found to be mainly additive on both moose and caribou populations. Kill rates by individual wolves were inversely related to pack size and unrelated to prey density or snow depth. Scavenging by ravens decreased the amount of prey biomass available for wolves to consume, especially for wolves in smaller packs. The kill rate by wolves on moose calves...
