White-tailed deer (Odocoileus virginianus) are among the most impactful herbivores in the eastern United States. Legacy forest effects, those accrued from intense herbivory over time, manifest as low seedling regeneration, high cover of plant species that are infrequently browsed by deer, presence or expansion of nonnative or invasive plant species, few herbaceous species, and diminished capacity for recovery. Interfering vegetation (that is, species that increase in cover and density due to avoidance by deer, such as American beech sprouts, Pennsylvania sedge, and hay-scented fern) increase competition for light and hinder recruitment of trees into the forest canopy.

This Natural Resource Report is the first of a five-part series in response to Agreement Number P14AC00469, which was awarded to the co-authors in response to Hurricane Sandy. Hurricane Sandy dramatically impacted coastal New England in 2012. Many areas of Fire Island National Seashore (40.669, -73.051) were inundated or eroded, and several primary dunes were overwashed by storm surge. The cooperative agreement addressed the following tasks: (1) assess effects of white-tailed deer browsing on vegetation establishment, growth, and development in key overwash zones on Fire Island National Seashore, (2) expand vegetation monitoring developed for the Sunken Forest into additional maritime forest

This Natural Resource Report is the second of a five-part series in response to Agreement Number P14AC00469, which was awarded to the co-authors in response to Hurricane Sandy. Hurricane Sandy dramatically impacted coastal New England in 2012. Many areas of Fire Island National Seashore, New York (40.669, -73.051) were inundated or eroded, and many primary dunes were overwashed by storm surge. The cooperative agreement aimed to address the following four research tasks: (1) assess effects of white-tailed deer browsing on vegetation establishment, growth, and development in key overwash zones on Fire Island National Seashore, (2) expand vegetation monitoring developed for the Sunken Forest into additional maritime forest zones on Fire Island, (3) document daily, seasonal, and annual movements of white-tailed deer on Fire Island, and (4) explore how access to food, thermal cover, and fresh water affect activity and space use of white-tailed deer between heavily urbanized western communities of Fire Island and the Wilderness Area. This report solely addresses objective (3) listed above. The remaining four reports in this series include three reports addressing each of the remaining objectives and a comprehensive report addressing Fire Island’s resilience to future disturbance.

The Department of the Interior Bison Conservation Initiative calls for its bureaus to plan and implement collaborative American bison conservation and to ensure involvement by tribal, state, and local governments and the public in that conservation. Four independently managed and geographically separated National Park Service (NPS) units in Interior Region 5 (IR5) preserve bison and other components of a formerly contiguous Great Plains landscape. Management of bison in IR5 parks has historically been specific to each park, and livestock and range management science informed much of the decision making. In the past two decades, NPS has shifted away from managing bison from this livestock-based perspective towards a wildlife stewardship approach, including ensuring their long-term adaptive potential and considering them as just one part of a complex ecosystem. This shift requires a more holistic and cooperative approach to stewardship that is challenging not only because of limitations in funding and fluctuations in leadership priorities, but also because of the constraints imposed by the parks’ relatively small, fenced areas.
