Science Tools for Managers

The thawing of ice-rich soils in permafrost landscapes, a process known as thermokarst, can result in profound impacts on the energy and water balance, carbon fluxes, wildlife habitat, and existing infrastructure in the local area. The Alaska Thermokarst Model is a “state-and-transition" model being developed to simulate landscape evolution in polygonal tundra landscapes commonly found on the Arc

Invasive species establish outside of their native range, spread, and negatively impact ecosystems and economies. As temperatures rise, many invasive plants can spread into regions that were previously too cold for their survival. For example, kudzu, ‘the vine that ate the south’, was previously limited to mid-Atlantic states, but has recently started spreading in New Jersey and is expected to bec

States in the Southeastern Association of Fish and Wildlife Agencies (SEAFWA) region have faced challenges when trying to develop regional plans or actions for many conservation issues. Leadership in many SEAFWA states is hesitant to approach the topic of climate change at all, let alone engage in multi-state efforts to mitigate climate impacts. Recent Southeast Climate Adaptation Science Center (

The Hawaiian Islands are both biologically and ecologically diverse. To better manage and understand this diverse landscape, detailed, reliable projections of future changes in climate are needed by Hawaiʻi resource managers, such as land managers, conservation organizations, and decision makers. Global climate models (or “general circulation models”) produce projections at regional or global scal

As the climate continues to change, vulnerable wildlife species will need specific management strategies to help them adapt to these changes. One specific management strategy is based on the idea that some locations that species inhabit today will remain suitable over time and should be protected. The climate conditions at those locations will continue to be good enough for species to survive and

The National Park Service is responsible for managing livestock grazing on 94 locations across the country and several grazing management planning efforts for this work are underway. However, there is a recognized need to update grazing management plans to address potential future effects of climate change on related resources and practices. This is the second phase of a project that is using scen

Climate Change threatens efforts to restore and protect the natural and cultural resources vital to the traditional ways of life of Northern California Tribes. The state has indicated the need to include Tribal science priorities and Tribal management objectives into regional planning and policy. Moreover, Governor Newsom’s recent Executive Order N-82-20 aims to combat the biodiversity and climate

Hawaiʻi’s native forest birds are known worldwide for their diversity and beauty. Unfortunately, many species are heading towards extinction because of bird malaria spread by mosquitoes introduced over a century ago. Remaining populations of these highly threatened forest birds tend to be at high elevations near the tree line on mountains, where cooler temperatures limit mosquitoes and malaria dev

Climate change has the potential to change the kinds and numbers of fish and wildlife that are available for recreationists such as hunters, anglers, and birdwatchers. While we have some knowledge about what changes might look like concerning different fish and wildlife species, very little information is known about how anglers, hunters, and wildlife watchers might view such changes in the areas

As pressures from climate change and other anthropogenic stressors, like invasive species, increase, new challenges arise for natural resource managers who are responsible for the health of public lands. One of the greatest challenges these managers face is that the traditional way of managing resources might not be as effective, or in some cases might be ineffective, in light of transformational

Recreational fisheries offer invaluable benefits to the communities they serve, including economic support, food security, and enhanced social connection with natural areas. In North America, bluegill are one of the most important species in terms of providing accessible, harvest-oriented recreational fisheries. In Wisconsin, they are the most caught, most harvested, and second-most targeted speci

The Northeast coast of the United States is an important area for a variety of native nesting seabirds including Common, Least, Arctic, and the federally endangered Roseate terns. These species migrate to the Northeast region to take advantage of highly productive waters during late spring and early summer to breed and raise their young. During this period, adults are highly dependent on local pre
