Prince William Forest Park is no stranger to dramatic changes in the environment. In the 1930s, the terrain was transformed from overused farmland into a natural retreat for recreational opportunities. Now, a changing climate primarily caused by the burning of fossil fuels is beginning to alter park resources and our park experiences. Explore the links and information on this page to learn more about climate change in Prince William Forest Park, and what you can do to help protect its resources.

Prince William Forest Park has a legacy as a
natural haven for people looking to enjoy the great outdoors. Since its designation as a Recreation Demonstration Area (RDA) in 1936, families have continued to come take advantage of its recreational opportunities. Today, a changing climate has and will continue to impact the ways we experience the park. Learn more about the impacts to recreation.

In 2011 Prince William Forest Park became a Climate Friendly Park in an effort to reduce the park’s contribution of the greenhouse gas (GHG) emissions that are causing our climate to change. Learn more about what it means to be a Climate Friendly Park, what actions we are taking, and how you can help make a difference.
 

Impacts to Prince William Forest Park Resources

 

Forest Health

Climate change, fire suppression and shifts in land use are changing the composition of our region’s forests.1 As forests shift towards a closed canopy, shade-tolerant species like the red maple, American beech, and black gum trees are increasing. At the same time, light-loving tree species such as the Virginia pine and black cherry are decreasing.1
Continued warming is allowing the region’s habitats to accommodate forest species traditionally found in areas farther south. Some native species are struggling to adjust to the changing climate. Invasive species, like Japanese stiltgrass, out-compete native plants for resources, which throws off the natural balance of the park’s ecosystems. Exotic pests like the emerald ash borer have already destroyed millions of ash trees in the northeastern U.S. and Canada.1 The EAB now is a major concern for the future of the park's white ash population. National Park Service staff are monitoring forest health and combating threatening invasive species.
 

Water Quality

The cleanest water in Northern Virginia flows through the network of streams and creeks in Prince William Forest Park. We are proud to protect a large part of the Quantico Creek watershed, including significant portions of the north and south forks of Quantico Creek. As the climate changes, so will our water quality. Increasing average air temperature will also raise water temperature, adversely affecting the species that keep the stream healthy, such as allowing nutrient depleting algae to flourish.2
Climate change will likely increase precipitation causing increased stream flow. This also disrupts the habitat of aquatic species such as benthic macroinvertebrates. This is important because macroinvertebrates are a crucial food source for amphibians, fish, and other creatures.3 More precipitation and extreme downpours also increase runoff of harmful chemicals and silt from nearby development into the water.Our efforts to protect aquatic habitats include regular monitoring of stream and lake quality.

Historical Cabin Camps

Prince William Forest Park preserves the highest number of Civilian Conservation Corps structures (166) in the National Park System. These structures and their rich historical value are vulnerable to changes in climate such as increases in temperature, humidity, and wind damage from more frequent and intense storms.5 Increasing moisture and temperature also increase the risk of damage from pest infestations. Prince William Forest Park’s five cabin camps are listed on the National Register of Historic Places. Park staff are working to protect them for future generations. Park staff focus on preserving the physical and historical integrity of these structures. This is accomplished through various renovation projects that improve the durability of the buildings while maintaining their authentic presence.
