The park is the largest protected natural area in the Washington, D.C. metropolitan region.. Today, the park is a window into the past and serves as an example of what much of the East Coast once looked like centuries ago. Prince William Forest Park is an oasis, a respite of quiet and calm. In 1936, Chopawamsic Recreation Area opened its gates to house children's 'relief' camps during the Great Depression. Renamed Prince William Forest Park in 1948, these fragrant woods and trickling streams have welcomed generations of campers, hikers, bikers and nature lovers.

Pawpaw: Small Tree, Big Impact Pawpaw are small trees that don't grow past 100 feet. Yet they have a big influence-- they're the most commonly observed sapling in our National Capital Region forests. Pawpaw trees are virtually immune to deer browse and also produce the largest edible fruit native to North America! A hand holds a lumpy green pawpaw fruit Lichens and Air Quality Lichens are durable enough to grow on tree bark and bare rock, yet are sensitive to pollution and air quality. One species in particular was used to track levels of air-borne lead over a 100 year period! Pale green lichen growing on rock. Instructing for Dangerous Missions Creating the training process was a big challenge. To prepare spies, saboteurs, guerrilla leaders, radio operators, psychological warfare specialists and commando teams for their clandestine missions, the Office of Strategic Services had to obtain instructors, prepare a curriculum, develop courses, and devise practical exercises. Daily Life in Camp Park and Town During the recruiting process, the Office of Strategic Services was looking for a combination of intelligence, imagination, courage and, if necessary, ruthlessness. Most of the young recruits, that volunteered for possible hazardous duty, craved the excitement and challenge of a special overseas assignment.

[Site Under Development] historic cabin camp site Field School at Prince William Forest Park: Documenting Cabin Camps Starting in summer of 2018, University of Mary Washington and NPS partnered for a field school at Prince William Forest Park. Students gained hands-on experience while helping to document two cultural landscapes, Cabin Camp 4 and Cabin Camp 2. The cabin camps were developed in the 1930s as part of the Recreational Demonstration Area program. This documentation will be used to complete CLI reports for the two camps, and the methods helped shape subsequent field schools. Two field school participants look at a drawing board as they document a forested landscape.

Summer in the Parks (1968-1976) What began as a summer transportation program to send DC urban youth to Catoctin and Prince William Forest Parks in 1966 grew to a city-wide summer-long festival attracting residents to parks in every quadrant of the city. After the assassination of Martin Luther King, Jr., the program took on an additional role to help save a city from destroying itself. A group of boys smiles for the camera Transforming Prince William Forest Park into Military Camps In 1942, the hilly, forested lands of Prince William Forest Park near Quantico, Virginia, became the site of training camps for the OSS Special Operations and the Communications Branches. Postwar Period: End of the OSS and Return to the Park Service The OSS may have won its battles in the field, but it lost its final campaign—in Washington. It was better prepared to fight armed enemies overseas than bureaucratic enemies in the nation’s capital. Summary and Conclusion The OSS training camps closed in 1945. The valuable contributions to the Allied victory made by those facilities and by Donovan’s organization itself are an important part of the history of World War II. OSS in Action The Pacific and the Far East Although the most publicized achievements of the OSS occurred in Europe and North Africa, Donovan’s organization also contributed to the war against Japan in the Far East. "Wild Bill" Donovan and the Origins of the OSS When World War II broke out in Europe in 1939, U.S. intelligence operations were splintered among nearly a dozen federal agencies.

Its espionage and sabotage operations were pioneered by an eclectic team that combined some of America's brightest minds with burglars and con men. Their work in World War II contributed to Allied victory. When the OSS was disbanded after the war in 1945, the Central Intelligence Agency (CIA) rose from its ashes.

Beech Trees in the National Capital Area American beech (Fagus grandifolia), the most common tree species in National Capital Area parks, is currently facing the emerging threat of Beech Leaf Disease (BLD). A forest with healthy green leafed beech trees Overview of the Urban Forests The eight urban forests measured in the Urban Ecology i-Tree analyses are diverse. The following articles explore just a few of the common ecological benefits the urban trees in these parks provide to the parks and the surrounding areas. Overview of the Urban Forests icon of tree silhouettes. Icon put over photo of Prince William Forest Other Benefits of Urban Forests Other benefits of urban forests include: Trees and Building Energy Use and Oxygen Production. Trees affect energy consumption by shading buildings, providing evaporative cooling, and blocking winter winds. Oxygen production is one of the most commonly cited benefits of urban trees. Other Tree Benefits icon of house with a tree besides it. Icon put over photo of cherry blossoms Structural Values of Urban Forests A tree’s structural value can be thought of as the cost of having to replace a tree with a similar tree. It can be calculated with factors like the tree trunk area and the tree’s health condition. Various insects and diseases can infest urban forests, potentially killing trees and reducing the health, structural value and sustainability of the urban forest. Structural Values of Trees icon of tree on field. Icon put over photo of snow covered trees. Avoided Runoff and Urban Forests Surface runoff, particularly from storms, can be a cause for concern in many urban areas because the large amounts of paved surfaces will increase the amount of water that cannot soak into the ground. These large volumes of stormwater runoff can carry surface impurities into streams, wetlands, rivers, lakes, and oceans, contributing pollution, garbage, and excessive nutrients into aquatic ecosystems. Urban forests, however, are beneficial in reducing surface runoff. Avoided Runoff icon of rain over a tree branch. Icon put over raindrops on red fall leaves Carbon Storage by Urban Forests Climate change is an issue of global concern. Urban trees can help mitigate climate change by storing carbon in tree tissue and sequestering atmospheric carbon from the key greenhouse gas, carbon dioxide (CO2). Carbon Storage & Sequestration icon of CO2 going into a tree. Icon put over photo tree trunk. Air Pollution Removal by Urban Forests Poor air quality is a common problem in many urban areas. It can lead to decreased human health, damage to landscape materials and ecosystem processes, and spoiled scenic views due to reduced visibility. The National Park Service monitors and assesses air quality in park units. The trees in NPS’s urban forests contribute to improved air quality. Air Pollution Removal Icon of green lungs.

Harmonica reed Forest Regeneration 2021 The latest look at forest regeneration capacity in National Capital Area national parks based on monitoring data from 2021. Green forest showing healthy understory of oak seedlings. Resilient Forests Initiative - Managing Deer Impacts 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. Deer impacts I&M Networks Support Resilient Forest Management NPS Inventory and Monitoring Networks have been tracking forest health in eastern national parks since 2006. This monitoring information can guide resilient forest management and support parks in adapting to changing conditions through the actions described below. Forest health monitoring Managing Resilient Forests. A Regional Initiative 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. Forest health monitoring Autumn Amphibians Frog antifreeze and red efts? Learn more about fall amphibian life in the National Capital Area, including marbled salamanders, spring peepers, and red-spotted newts! A red-orange juvenile red-spotted newt climbs a rock Series: Managing Resilient Forests Initiative for Eastern National Parks Forests in the northeastern U.S. are in peril. Over-abundant deer, invasive plants, and insect pests are 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. Healthy forests have many native seedlings and saplings. Resilient Forests Initiative - Managing Invasive Plants & Pests Park forests are threatened by invasive plants and pests. Strategically tackling invasive plants to protect park’s highest priority natural resources and planning around forest pests and pathogens are important actions in managing resilient forests. Forest Regeneration Ash Tree Update 2021 Emerald ash borer (EAB) has killed most of the 300,000 ash trees in National Capital Region parks since 2014. Fewer than 80,000 living ash trees remain. Some ash-dominated swamps transformed into shrublands as ash root systems re-sprouted after EAB attack. In dry habitats, EAB proved more quickly fatal.
