Volunteer Archivists Decipher Thousands of Untold Stories from the American Revolution 18th-19th Century pension documents hold fascinating stories of the everyday people touched by the American Revolutionary War. Today, any volunteer with a computer can reveal those stories by transcribing the documents. A science-writer intern discovered the story of Sarah Martin, the widow of a New Jersey militiaman. Two historic documents. Community Volunteer Ambassadors The primary duty of the Community Volunteers Ambassadors is to encourage local residents, particularly young people, to volunteer for climate-resilience-related projects in the park.

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. Person gazes up at a tall tree The Section 106 Slow-Down: Diagnosing and Averting Harm to Cultural Resources at Valley Forge Valley Forge National Historical Park exemplifies the benefits of the Section 106 review process. The park has conducted archeological investigations prior to renovations, installations, and even additions to the natural landscape. These efforts have disclosed thousands of previously unknown precontact and historic artifacts, evaluated sites’ integrity, and authorized—and sometimes revised—construction activities in the interest of protecting the past. Person standing in an excavation grid Dinosaurs of the National Park Service Dinosaur fossils have been discovered at or are associated with at least 27 NPS units. Geographically, their finds are concentrated in the parks of the Colorado Plateau, but they have been found from central Alaska to Big Bend National Park in Texas to Springfield Armory National Historic Site in Massachusetts. The most famous site is the Dinosaur Quarry of Dinosaur National Monument, but a rush of new finds since the 1970s has greatly expanded our knowledge. allosaurus fossil Knox Covered Bridge Learn about the Knox Covered bridge, it's link to the past and rebuilding it for the future.

A Meeting of Minds, Methods, and Peoples: Public Archeology at Washington’s Headquarters Instead of relegating precontact artifacts to the periphery because they did not fit the project’s focus, the 2009-2011 projects realize a more complete picture of occupation in the Washington’s Headquarters area. Treating all artifacts and features as worthy of preservation and study enhances the layers of history embedded—and often obscured—within the larger cultural and historical landscape of Washington’s Headquarters. Stone gorget Making Way for an Army: Archeology at Muhlenberg’s and Weedon’s Brigades Archeological projects over the last 50 years have sought to reconcile historic accounts with reality at Valley Forge, including events surrounding the site of Muhlenberg’s Brigade . By considering each hut both individually and in relation to one another, archeology at Valley Forge personalizes the starkness of the soldiers’ six-month stay and details the ingenuity with which they tailored their surroundings to their needs. Redward ceramic container Inventory & Monitoring Partnerships Aim to Improve Park Forest Health from Coast to Coast 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.

Over the past two decades an increasing number of deer has resulted in undesirable changes in the species composition, structure, abundance, and distribution of native plant communities, particularly forests. Browsing of tree and shrub seedlings by deer has eliminated the ability of forests to regenerate, leading to monocultures of invasive plants, such as Japanese stilt grass, above. Future management will focus on the protection, preservation, and restoration of forests and other native plant communities.

The Rusty Crayfish The rusty crayfish is considered a non-native, invasive species in the park and throughout Pennsylvania. Originally from the Ohio River Basin, this crayfish has been introduced into 19 states where it never occurred before over the last 30-40 years (Figure 2). It has been transported from one place to another primarily by bait fishermen, but also through biological supply houses, aquaculture, and the pond and aquarium trade. Rusty crayfish were first documented in Pennsylvania in the 1970’s and now occur in the Delaware, Potomac, Schuylkill, and Susquehanna River watersheds. From large rivers they are able to invade the countless small streams that feed into the rivers, such as Valley Creek. What does invasive mean? An invasive, non-native species is one that, once introduced, is able to out-compete native species for needed resources such as food, space, water, and shelter. In extreme cases, native species may be totally eliminated from the ecosystem. The rusty crayfish is bigger, more aggressive, and eats up to twice as much as native crayfish in Valley Creek. They are able to eliminate ALL other crayfish species through direct competition for food and shelter and increasing the susceptibility of native crayfish to predators as they are chased from under protective rocks and move more to find food. Rusty crayfish also may reduce the amount of aquatic vegetation, reduce aquatic insect populations, and ultimately negatively effect large predators such as trout.

It is illegal to use rusty crayfish as fishing bait in Pennsylvania and no live bait of any kind can be used in Valley Creek within the park. These regulations exist to prevent the introduction of additional non-native species into Valley Creek and to control the spread of rusty crayfish across the state. www.nps.gov/vafo Funding contributed by the National Park Service Volunteer-In-Parks Program What is the Crayfish Corps In 2008, the rusty crayfish (Orconectes rusticus) invaded Valley Creek in Valley Forge National Historical Park. Valley Creek is considered an “Exceptional Value” waterway, Class A Wild Trout Fishery, and one of the park’s most important natural resources. The rusty crayfish is a highly aggressive, non-native species that poses a significant threat to the continued health of the stream ecosystem. Rusty crayfish claws are grayish– green to reddish-brown with dark black bands on the tips (b). The claws, when closed, have an oval gap in the middle. The moveable claw is smooth and S-shaped (c).

Valley Forge National Historical Park King of Prussia, Pa National Park Service U. S. Department of Interior Preventing Lyme Disease The More You Know The Easier It Is What is Lyme Disease? Lyme Disease is a bacterial infection which acquired its name from Lyme, Connecticut, where the first cases were diagnosed in 1975. The Centers for Disease Control currently lists Lyme Disease as the most common tick-borne illness. Although reported throughout the United States and Europe, in the United States it is most prevalent in the Northeast and mid-Atlantic states. Caused by the bacterium Borrelia burgdorferi, Lyme Disease is most commonly transmitted to humans through the bite of the deer tick or black legged tick (Ixodes scapularis, formerly Ixodes dammini). The tick becomes infected when it takes a first blood meal from the white-footed mouse, its primary host. Recognizing the Deer Tick Deer ticks often go unobserved because of their small size compared to the common dog tick (which also may transmit Lyme Disease). There are three stages in the life cycle of the deer tick: larva, nymph, and adult. During the larval stage it is the size of the head of a pin. The adult reaches the size of a sesame seed unless it has just fed, then it may grow up to four times normal size. Ixodes scapularis nymph compared to a human thumb These deer ticks are shown actual size: larva nymph adults blood-engorged adult tick How and Where the Tick Lives In the Northeast, larval deer ticks hatch and take a first blood meal in August, often from the white-footed mouse – the carrier of the Lyme Disease bacterium. This is usually when ticks become infected with Lyme Disease. Fully engorged larvae drop to the ground then emerge as nymphs the following Spring. Nymphs (and in Fall the adult ticks), then transfer to a larger host. Lyme Disease can be transmitted to humans if they encounter a tick at this time and become the secondary host. It is common for nymphal and adult ticks to attach to dogs, cats, birds, squirrels, raccoons, foxes, mice, deer, etc. The primary role that deer and other wildlife such as birds play in the spread of Lyme Disease is in the transport of potentially infected ticks into the home environment. Additionally, abundant hosts may support a higher than normal tick population compared to areas with fewer host species. Ticks spend most of their lives in moist, humid areas with abundant host species. Although found in all natural environments at Valley Forge National Historical Park, research indicates that the highest tick densities are in wooded areas. Ticks can be found on shrubby vegetation less than 3 feet in height, the undersides of leaves, logs, and in leaf litter. Structures such as stone walls, particularly when located within wooded areas of the park, are also favored locations for ticks. Student collecting ticks using a drag cloth Transmitting Lyme Disease to Humans Although tick larvae do bite humans, they are unlikely to be a carrier of the Lyme Disease because they have not yet been infected. The most dangerous period for transmission of Lyme Disease to humans is during the nymphal stage because nymphs are most likely to feed on a person and are still small enough to be difficult to detect. The adult tick transmits the disease, but they are usually large enough to see and are often spotted and removed quickly. Peak months for nymphal and adult deer ticks in this area are May, June, July, and October. If a tick is attached to your skin for less than 24 hours your chance of getting Lyme Disease is very small. Prompt removal of ticks may substantially reduce the probability of acquiring Lyme Disease from a tick bite. How to Remove a Tick The more quickly you remove a trick from your body, the better your chances of avoiding infection. To safely remove a tick, grasp it firmly with fine-point tweezers where the mouthparts enter the skin. Without squeezing the body of the tick, tug gently until it releases its hold and then wipe the bite area with antiseptic or wash with soap and water. Lyme Disease Symptoms The majority of Lyme Disease cases are reported in June, July, and August. Early symptoms usually occur from a few days to a few weeks after infection, although it could be up to one a month. If recognized early it is easily treated with antibiotics. A vaccine is also available. Ask you doctor about this option. Early Symptoms The onset of Lyme Disease is usually accompanied by flu-like symptoms that include one or more of the following: fatigue, chills and fever, headache, muscle and joint pain and/or stiffness, stiff neck, discomfort in the jaw area, red eyes, and swollen glands. As many as 50% of the people who are infected with Lyme Disease also develop a RED RASH at the site of the initial bite. The rash is often round and may expand up to 18 inches in diameter over a number of weeks. The center of the rash may clear as it expands creating a “bulls-eye” effect. The rash can have several
