Geology of Harpers Ferry 
Saturday, April 11 (10 am-3 pm)
Leader: Joe Marx
Members $30; nonmembers $42
The town of Harpers Ferry sits astride the junction of the Potomac and Shenandoah Rivers, in the shadow of a spectacular water gap. The combined streams slice through the Blue Ridge, exposing ancient rocks that formed from coastal plain deposits along the edge of an earlier, smaller version of North America. We will walk 5-6 miles along the towpath of the C&O Canal, upstream from the railroad bridge and back. Occasionally, we’ll stop to look at local stones incorporated into the canal wall or step down to the river and examine rock exposures kept fresh by the flowing water. The pace set and distance covered on these geology trips is typically faster and farther than our usual “naturalist’s shuffle.”

Introduction to the Geology of the Mid-Atlantic  FULL
Thursday, April 16 (7:30-9:30 pm)
Leader: Joe Marx
Free, but registration required.
Join Joe Marx, Natural History Field Studies Geology teacher and ANS field trip leader, for a rockin’ lecture at our Woodend Sanctuary.

The Secret Lives of Spring Wildflowers
Saturday, May 2 (9 am-Noon)
Leader: Sujata Roy
Members $24; nonmembers $34
They’re lovely to behold. But their beauty belies the scrappy, survival strategies of our region’s short-lived spring wildflowers. Coping with cold temperatures, they must race to complete their flowering and fruiting cycles before the brief window of spring sunlight gets shut out by the unfolding forest canopy. NHFS Spring Flower instructor Sujata Roy will spill some of their secrets in an exploration along the C&O Canal at Great Falls, MD.

Springtime in West Virginia FULL -REGISTER FOR WAITLIST ONLINE
Monday, May 4 (8 am) -Tuesday, May 5 (4 pm)

Enjoy early spring all over again by heading upward in elevation to the Appalachian peaks and hollows of West Virginia. On this broad-based nature foray, highlights will include migrant songbirds, spring wildflowers, early season butterflies, and perhaps a salamander or two. We'll take modest hikes of a mile or two in different habitats each morning and afternoon. Our explorations are based in the Canaan Valley area, but depending on the weather we may also visit Dolly Sods, Seneca Rocks, and/or Blackwater Falls. Overnight options range from campgrounds and basic cabins to motels and park lodges. Participants are responsible for their own lodging arrangements.

Black-throated Blue Warbler NGM-v31-p312-DBird ID Series: Spring Warblers

Thursday, May 7 (7-9 pm)
Sunday, May 10 (7 am-1 pm)
Leader: Mike Bowen
Members $46; nonmembers $64
Lecture only members $20; nonmembers $28

More than 30 species of warblers pass through the Mid-Atlantic during spring migration -- but finding and properly identifying these active songbirds can be a real challenge. We’ll use slides and recorded warbler songs for the Thursday lecture. On Sunday we’ll start early and visit several spots along the C&O Canal, where we’ll hope to hear and see a wide variety of warblers.

 

Window into the World of Fungi

Thursday, May 7 (7-9:30 pm)
Leader: Tovi Lehmann
Free, but registration required.

Rooted, yet not plants, heterotrophs, but not animals (growing in fairy rings, yet not even fairies), fungi are members of another kingdom. Mostly hidden under the surface, fungi have evolved their own solutions to life’s persistent problems. Gaining the recognition for their pivotal role in shaping the living world, they now reshape fundamental perceptions of biologists. In this lecture at our Woodend Sanctuary, we will explore the natural history and ecology of our local fungal neighbors, rather than focus on the edibility of particular species of mushrooms.

 

Spring on the Appalachian Trail

Saturday, May 9 (full day hike)
Leader: Stephanie Mason
Members $34; nonmembers $46

One of the best ways to explore the seasonal richness in our region’s along the Appalachian Trail. Our Senior Naturalist leads this search for spring blooms, butterflies, and breeding bird activity amongst the rocky terrain of Maryland’s South Mountain. Beginning at Gathland State Park, the former estate of a Civil War correspondent, we’ll hike to the summit of Lamb’s Knoll before ending the day at Fox Gap. We’ll cover 6 miles on this moderately strenuous uphill/downhill hike on trails that will be rocky and uneven. We’ll stop to observe natural phenomena, but will keep a pace necessary to cover the distance stated.

 

Appalachian Spring

Sunday, May 10 (8:30 am-3 pm)
Leader: Cathy Stragar
Members $30; nonmembers $42

Spring rains, warming temperatures, and longer hours of daylight ignite a great burst of life in the valleys and ridges of the Appalachian Mountains. Nowhere is this more evident than at the Thompson Wildlife Management Area in the Blue Ridge Mountains near Linden, VA, a wildlife reserve that is well known for its botanical diversity. Our field trip will focus on the rich wildflower display, as well as spring migrants, butterflies, and other wildlife. We’ll cover around 3 miles at a leisurely pace, but there will be uphill and downhill walking on rocks and uneven trails.

 

MountainLaurelSpring Woods of Prince William Forest Park

Saturday, May 16 (9 am-12:30pm)
Leader: Elizabeth Rives
Members $24; nonmembers $34

With 15,000 acres of forest, Prince William Forest Park protects the largest Piedmont forest in the National Park Service and the largest green space in the DC-metro area. Here plants at their northern-and-southernmost limits meet and overlap, as do species from both Coastal Plain and Piedmont. The leader of our winter visit here returns for a late spring walk to look for seasonal wildflowers, shrubs, and trees. Mountain Laurel should be in bloom along our 2-3 mile hike over sloping terrain on natural surface trails. Bring along a bag lunch to enjoy with the leader after the walk. Note: $5 per car entrance fee. Carpooling will be encouraged and facilitated.

Our leader describes this protected area in Central Baltimore County as the “best walk in the Maryland Piedmont.” We’ll explore several woodland types in our search for wildflowers such as Nodding Trillium and Miterwort, among others, but all manner of spring botanical interest will be our focus. We’ll make frequent stops to study plants on our walk of around 2 miles along a narrow woodland trail, with a couple of stream crossings.

 

Introduction to Bird ID by Voice

Tuesday, May 19 (7:30-9 pm)
Thursday, May 21 (7:30-9 pm)
Saturday, May 23 (7 am-Noon)
Leader: Mark England
Members $46; nonmembers $64

The sounds made by birds can help find and identify many species, yet to beginning birders, the wide variety of sounds can be confusing. If you know many of our area birds by sight but not by sound, this class is for you. Two evening sessions will use recordings and slides to study bird songs and calls. Our field trip to one or more sites in Montgomery County will give us a chance to listen for and try to learn some of the local species.

 

Spring Shorebird Migration on the Delaware Bay  FIELD TRIP FULL - REGISTER FOR WAITLIST ONLINE

Saturday, May 30 (full-day field trip)
Leaders: John Bjerke and Cyndie Loeper
Members $46; nonmembers $64
Lecture only members $20; nonmembers $28

Each year in May, horseshoe crabs migrate to the beaches of Delaware Bay to mate and lay their eggs. During the same time period, hundreds of thousands of shorebirds, en route to summer breeding grounds, stop at the Bay to feast and refuel on the concentrated number of horseshoe crab eggs. At Thursday’s lecture, we will discuss shorebird migration and use slides to help ID some of the most common shorebirds in our region. Saturday’s field trip will take us to the Bay, where we will hope to see and ID a variety of shorebirds.

We’ll also consider satyrs and other less-noticed butterfly species in our evening lecture at Woodend led by regional butterfly expert Dick Smith. Our field trip to Patuxent Research Center-North Tract will offer opportunities to see some confusing and hard-to-ID species, as well as the more common ones. Our Senior Naturalist will assist with ID of butterfly host and nectar plants.

The County’s forest ecologist leads us on a summer exploration of another “botanical gem” in this ongoing series. Come prepared to walk from 1.5-2 miles in lush floodplain forest along the Potomac River in Dickerson Conservation Park. While the focus of the hike will be to learn about the range of native trees, shrubs, and summer wildflowers in this rich habitat, the highlight will be the chance to visit some towering, old trees, including the largest known tree in the state of Maryland, a giant sycamore.

 

PineBarrensWilds of South Jersey: Little Pines and Big Marshes

Monday, July 27 (8 am) to Tuesday, July 28 (4 pm)

Leader: Mark Garland

Members $110; nonmembers $154

Join a seasoned Jersey naturalist on a visit to two very different but wild and unspoiled habitats in southern New Jersey. On Monday, we’ll explore the Pine Barrens, where deep quartz-rich sands support hilltop forests of stunted oaks and pitch pines. In the lower spots, tea-colored rivers are lined with bogs where rare plants thrive. The next day, we’ll visit the vast marshes lining the Delaware Bay in Cumberland County, New Jersey, where we can expect to see a good variety of shorebirds, herons, and other water birds.  Expect open and sunny field conditions on our two days of explorations. Overnight options include motels in Vineland (about 2.5 hours from our Woodend Sanctuary and about 30 minutes from our field sites) and campgrounds in the Pine Barrens. Many chain motels can be found in and around Vineland. Suggestions will be sent with the program confirmation. Program fee does not include lodging.

 

Native Plant Gardening for Homeowners
Summer Walk: Wednesday, July 29 (10 am-Noon)
Fall Walk: Wednesday, October 21 (10 am-Noon)
Leader: Stephanie Mason
Each walk members $20; nonmembers $28
Explore the Blair Native Plant Garden, located just outside the Sanctuary Shop, with our Senior Naturalist who helped develop the garden and its educational focus. Find out more about the values of gardening with native plant species, including: lower maintenance; more value to native birds, butterflies and other insects, including pollinators; reduced negative impact on local ecosystems, and more. We'll discuss native alternatives to popular non-native species such as English ivy, as well as resources for broadening one's knowledge and understanding of plants natives to the mid-Atlantic. You're welcome to bring along a bag lunch to eat with the leader after the walks, which are scheduled to highlight seasonal aspects of the Garden.
