Birds

Under the Endangered Species Act, the U.S. Fish and Wildlife Service (USFWS) must evaluate the status of at-risk plants and animals in the U.S. A Species Status Assessment (SSA) is a scientific assessment prepared for each at-risk species to help inform a range of management decisions under the Endangered Species Act. SSA’s are currently needed for more than 350 species, 250 of which are...

Hawaiian forest birds play important roles in many ecological processes. For example, 61% of native flowering Hawaiian plant species are either bird pollinated or dispersed through ingestion by birds. However, native bird communities across Hawaiʻi continue to decline despite efforts to control predators and enhance habitat. These declines are, in part, due to the mosquito-borne avian...

The Nisqually River Delta represents the largest wetland restoration in the Pacific Northwest. The restoration resulted in a 50% increase in potential salt marsh habitat. The Delta supports threatened salmon fisheries, large populations of migratory birds, and provides unique opportunities for recreation. The Delta also provides multiple ecosystem services, which are the benefits that...

The impacts of climate change are widespread and accelerating. As natural resource managers are tasked with maintaining and protecting species and ecosystems, options for minimizing the impacts of climate change are needed. One option for climate adaptation focuses on resistance, which seeks to preserve, as much as possible, the historical structure, composition, and function of an...

Ecosystem services, or the benefits that natural ecosystems provide to people, are inherently spatial, tied to the specific ecosystems that create them. Mapping where ecosystem services are abundant or in short supply and identifying what lands provide certain services is useful for a variety of purposes, including land-use planning and assessment of conservation and restoration...

Sea level rise is likely to be a major driver of coastal habitat change in the coming decades, and therefore influence the location and magnitude of ecosystem services provided by coastal habitats. We used a spatial model to map coastal habitat changes due to sea level rise in six mid-Atlantic states, including North Carolina, and translate habitat changes into effects on net carbon flux...

Natural resource managers are confronted with the pressing challenge to develop conservation plans that address complex ecological and societal needs against the backdrop of a rapidly changing climate. Climate change vulnerability assessments (CCVAs) provide valuable information that helps guide management and conservation actions in this regard. An essential component to CCVAs is...

Many animal species have unique characteristics that allow them to survive during winter. For example, the snowshoe hare changes its fur color from brown to white to camouflage better in winter months, and the ruffed grouse roosts under the snow to stay warm and hidden in winter. These winter-adapted species, however, are facing new challenges as climate change is resulting in shorter...

The objective of this project is to map the supply of ecosystem services (where natural ecosystems have the capacity to provide a certain product or service that could be of use to people), use of those services (where people or other entities that use the product or service exist), and the condition of ecosystems providing these services over time. The resulting datasets were used to...

The North Carolina Natural and Working Lands Action Plan, part of the North Carolina Climate Risk Assessment and Resilience Plan, was created in response to Executive Order 80 to identify opportunities for North Carolina’s natural and working lands (NWL), including farms, forests, and wetlands, to sequester carbon, support ecosystem and community resilience, and enhance the state’s...
