Celebrate the beginning of the winter season at Chapman Forest (Chapman State Park) with its spectacular scenery and remarkable diversity of native plants, wildlife, and natural communities!

This year, we will visit the old-age forest section of the Mount Aventine Ravine to the marl cliffs and ravines near Glymont along the Potomac River. It has been over a decade since we've traversed this area. The 800-acre north section of Chapman Forest is a fascinating and regionally unique meeting ground for plants with a primary range in the inner Piedmont and mountains and those of the Coastal Plain.

Most of the ravines and rolling valleys throughout the forested tract between Mount Aventine and Glymont comprise a globally rare natural community called Shell-Marl Ravine Forest, coined by Harvard botanist M.L. Fernald in the 1930s after discovering similar forest communities in the Virginia tidewater region to the south.

This community type occurs only on the Coastal Plain where river bluffs and deep ravines over millennia have exposed underlying calcareous and glauconitic marine sands and marl beds deposited during the Paleocene, Eocene, and Miocene epochs when the area was a shallow sea at the western edge of the Atlantic Ocean. The Brightseat and Aquia Formations are the prominent underlying strata in this section of Chapman Forest.

The combination of deep ravines, calcareous soils, and close proximity to the Potomac River has produced a remarkable flora predominantly composed of species typical of the inner Piedmont and carbonate areas of the Appalachians that are otherwise rare to absent on the Coastal Plain, especially in association. Chapman Forest is considered to be Maryland’s largest and finest example of this natural community type.

During this year’s trip, we’ll see a diversity of species and natural communities, including Maryland state champion Pagoda Oak (Quercus pagoda), Chinquapin Oak (Quercus muehlenbergii), and Dwarf Hackberry (Celtis tenuifolia). We’ll also see old-age Tulip Tree (Liriodendron tulipifera), White Ash (Fraxinus americana), American Beech (Fagus grandifolia), American Basswood (Tilia americana var. americana), Winter Grape (Vitis vulpina), Bitternut Hickory (Carya cordiformis), Pignut Hickory (Carya glabra), Sweet Pignut Hickory (Carya ovalis), Sassafras (Sassafras albidum), Sweetgum (Liquidambar styraciflua), Sycamore (Platanus occidentalis), and other trees such as American Hop-hornbeam (Ostrya virginiana), Slippery Elm (Ulmus rubra), Red Mulberry (Morus rubra), Shumard Oak (Quercus shumardii), Deam’s Oak (Quercus x deamii), Swamp Chestnut Oak (Quercus michauxii), Paw Paw (Asimina triloba), and others.

Bring: Wear sturdy shoes and bring lunch or snacks and water. Most of the walk traverses rolling, fairly open forest along trails, though some steep grades will occasionally be encountered.

Directions: Take Indian Head Highway (Rt. 210) south from Capital Beltway (495). Proceed south on Rt. 210 for app. 15 miles. Continue on Rt. 210 past the Rt. 227 intersection at Bryans Road (McDonald's, Burger King, and shopping center on right and large CVS and builders supply will be on left) and start looking for Chapman Landing Road on right. Take half right on Chapman Landing Road and proceed a couple of miles to the entrance to Mount Aventine (Chapman State Park) on the right. Park and meet in the small parking lot at the entrance gate (additional parking is available along the shoulder of Chapman Landing Road, though please be extra mindful of the neighboring residents and careful not to damage the road edges when parking).

Carpooling: For those interested in carpooling to the field trip – or has room to provide a ride – please email Kathy Bilton at kathy@fred.net closer to the time and she will send out a list of names, general location, and contact info which she has received so that folks wishing transportation to the field trip can arrange something. A number of folks in the Alexandria-Arlington-D.C. area will likely be looking for a ride to the site.

Notes: For folks who aren’t able to stay the full time, there will be numerous points throughout the field trip to depart from and easily get back to the parking area.

Cancellations: In the event of heavy-steady snow, sleet, pouring rain, or icy, dangerous conditions of roads, the field trip will be cancelled.

Recognizing tree species in winter can be challenging, but there are tricks such as learning about bark, buds,, branch arrangement and habitat. The area we will visit has an extraordinary number of tree species in varied habitats. Marney is a long-time member of MNPS who has a love of trees in all seasons.

Leader: Marney Bruce

Location: Carderock Recreation Area

Notes: Dress for the weather and wear sturdy shoes._

For ages 16 years through adult

Learn to identify some of our evergreen plants.  We’ll explore the meadows and forest in search of the ferns, herbaceous plants, and trees that are green in the winter.

For adults, although teens 16 years and older may attend.

All trees do not look alike in winter! We'll learn the basics of plant identification using winter keys and field guides, then take a hike to use our knowledge (so make sure you bring outdoor weather clothes). This program is designed for those with little or no experience and will focus on twigs, buds, and bark. Geared for adults, but teens 16 or older may attend.

Wear warm clothes for standing around outside (we won't be moving very fast). Bring a snack or lunch if you think you'll get hungry. (Optional, but useful) a 10x hand lens, binoculars, field guides (we'll have some to lend out).
