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.

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.

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.

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.

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.

Hidden in Plain Sight: Old Growth Remnant Grasslands
During 2024 scouting for a large eastern grassland restoration project funded by IRA and BIL, several old growth remnant grasslands were identified in National Capital and Northeast Region parks that were previously unknown. These remnants preserve the genetic integrity of the original grassland flora of the eastern US and are true unexpected treasures that in some cases, were hidden in plain sight.

Forests at Valley Forge
Forest condition was first evaluated in 1983, and
was described as excellent. 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.

Did You Know?
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.

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.

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.

These deer ticks are shown actual size:

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.

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
