Since its establishment in 1903, the National Wildlife Refuge System (NWRS) has grown to 635 units and 37 Wetland Management Districts in the United States and its territories. These units provide the seasonal habitats necessary for migratory waterfowl and other species to complete their annual life cycles. Habitat conversion and fragmentation, invasive species, pollution, and competition for water have stressed refuges for decades, but the interaction of climate change with these stressors presents the most recent, pervasive, and complex conservation challenge to the NWRS. Geographic isolation and small unit size compound the challenges of climate change, but a combined emphasis on species that refuges were established...
Since the 1960s the rate of change of greenhouse gas concentration, radiative forcing and climate warming has been, and will continue to be, more rapid than previously known in geological history. As a result, biomes, species distributions, hydrology and the cryosphere will undergo profound changes. It will threaten some cultural resources and change visitor activities, satisfaction and safety. Protected area management cannot contribute significantly to climate change mitigation, but it can help nature adapt to it, and help society to understand its causes and consequences. The tools for managers are: research and monitoring; awareness and engagement; leading by example; and action on the ground. The management...
The rich and diverse natural resources of Denali National Park in Alaska are managed by the US National Park System as regulated by Park laws and the Alaska National Interest Lands Conservation Act. This Act prohibits snow machine use within a designated wilderness area, a law which has been challenged by recreationalists. This examination of the legal discretion of the Park authorities to enforce this law focuses on snow machine policy, scientific evidence of impacts to the natural environment, management objectives for this Park, National park Service authorization for regulating visitor uses of the park, and agency decision making in general.
Interpretations of "wilderness" in North America are widely varied. As such, the values attributed to wilderness also vary. The most common approach to wilderness protection-protected area planning and management-generally attempts to strictly define wilderness, or restricts its definitions unintentionally, thereby limiting the capacity of the protected area to protect the diversity of interpretations of wilderness. This study uses techniques of literary criticism to examine the management plans of six protected areas in northern Canada and Alaska to understand the possibility of the persistence of this interpretive diversity within the language of the plans. Because of the inability of the plans, as legal documents,...
Community Conservation Plans and annual screening reports on development proejcts for the Inuvialuit Settlement Regions.
This thesis uses a literature review of protected areas selection, park management, comprehensive regional land use planning, and cumulative environmental effects and assessment to develop a methodology that identifies areas with concentrations of social and/or ecological values in and around northern national parks. The proposed methodology involves two stages. First, a database of values is developed by taking an inventory of social and ecological values through extensive literature reviews, interviews, and consultation with the public. This database is then used in the second step to determine areas with concentrations of social and/or ecological values, or "value hotspots", using a series of tables and maps....
