The National Park Service will improve the ecological health of eastern forests in 38 parks using an array of management techniques. The NPS has selected forest ecosystems of high ecological and cultural value across multiple parks from Virginia to Maine that are at greatest risk of forest loss due to chronic and interacting stressors.

From coast to coast, the NPS Inventory and Monitoring Division is helping park managers improve the health and function of forest ecosystems. From promoting resilient forests in the Northeast, to conserving whitebark pine in the West, to protecting Hawaiian forest birds from avian malaria, scientific partnerships are helping parks to share information, leverage funding sources, and work together for outcomes that extend beyond what any park could accomplish on its own.

In Appalachia, forests are crucial to the health of ecosystems and local communities in and around National Parks. However, forest health monitoring in eastern National Parks has shown that park forests are rapidly changing, and don’t have enough tree regeneration to replace canopy trees as they fall or die. Bipartisan Infrastructure Law funds are being used to support the Resilient Forest Initiative in the restoration efforts within these parks.

A healthy forest needs to have enough tree seedlings and saplings to regenerate the forest canopy after a disturbance. Analysis of NPS I&M and other long-term datasets makes it clear that many eastern national parks lack adequate tree regeneration due to decades of over browsing by white-tailed deer.

Forests cover tens of thousands of acres in eastern national parks and these critical resources face a range of interacting stressors: over-abundant white-tailed deer populations, invasive plant dominance, novel pests and pathogens, among other threats. The Resilient Forests Initiative will help parks address these issue collectively.

Forests in the northeastern U.S. are in peril. Over-abundant deer, invasive plants, and insect pests are negatively impacting park forests, threatening to degrade the scenic vistas and forested landscapes that parks are renowned for. With regional collaboration, parks can manage these impacts and help forests be resilient. This article series explores tools available to park managers to achieve their goals.

Faced with threats like sea level rise and erosion, the freshwater tidal wetlands at Kenilworth Marsh and Kingman Lake may have challenges ahead. Scientists with the Inventory and Monitoring Program collected and analyzed marsh elevation data to determine how the ecosystems are weathering these changes.
