Come see the transformative power of volunteers! The Community Native Planting Project (CNPP) will be giving a guided tour of two of its sites that will show the Before, During, and After stages of invasive removal and native planting. We will visit two locations that started as invasive-filled vacant lots that were used for illegal dumping - until CNPP and its volunteers began work to turn them into thriving native plant habitats. We will be highlighting the various aspects that go into reclaiming seemingly hopeless sites and how others can do it, too!
Leader: Diane Beedle
Level of Difficulty: Somewhat difficult to difficult - This trip is not recommended for people with difficulty walking. We will be visiting two different sites that are a few blocks apart. One site has very difficult terrain with a variety of tripping hazards. Both have somewhat steep inclines. No bathroom facilities.
Diane Beedle is the president and cofounder of Community Native Planting Project (CNPP.) She is a Chesapeake Bay Landscape Professional (Level One), a Maryland Master Naturalist, and a former board member and treasurer of the Maryland Native Plant Society.

Description: Patuxent Research Refuge, North Tract. The Patuxent Research Refuge has documented over 1200 plant species due to the wide variety of habitats in its 12,000 acres. The North tract is particularly diverse with sandy soils on maintained powerline cuts that contain an array of late summer flowers, particularly Asteraceae. This field trip will jump between different locations to allow the exploration of different habitats. We will meet at the visitors center and car pool so we can travel between stops. Walking is on flat gravel roads and along the park roads.
Leaders: Clare Walker, Helen Lowe Metzman, and Robert Ferraro
Level of Difficulty: Easy. Some walking from the visitor center and some driving short distances to sites nearby.
Clare Walker teaches plant identification classes for Nature Forward and leads walks associated with those classes. Helen and Robert have been volunteers for Patuxent for many years, documenting plant species on the refuge and curating the herbarium. The three have led numerous walks on the refuge and are very familiar with the diverse array of plants occurring in various habitats, some of which are unique to the refuge.
Helen Lowe Metzman is a D.C. native who grew up with the Washington Beltway in her suburban backyard. Helen escaped to nearby Northwest Branch in search of wild flora and fauna. Her interest in natural history led her to the University of Vermont, where she studied Wildlife Biology and Environmental Education. Helen worked as a naturalist, illustrator and graphic artist, for Howard County’s Department of Recreation and Parks in the Natural Resources Division and studied ethnobotany. For fifteen years, she was garden director and educator for USDA botanist James A. Duke’s Green Farmacy Garden, a medicinal plant garden located in Fulton, Maryland. In 2017, Helen began volunteering at the USGS Bee Lab, using high-resolution macrophotography equipment to photograph native plants from Howard County and the Patuxent Refuge. In 2020, Helen joined Patuxent's Plant Inventory Project and Herbarium Team and started exploring and documenting the refuge's diverse flora. Currently, Helen serves on the board of Friends of Patuxent as a co-vice chair and on the board of the United Plant Savers - a native medicinal plant conservation organization. Helen has lived on 4.5 acres in Howard County for over 38 years, attempting to replace an onslaught of invasives with native plants while remaining in awe of the natural world.
The Greenbelt Forest Preserve is a 225 acre parcel of the original forest that once surrounded the City of Greenbelt. Some of this woodland adjoins the extensive pine barrens communities that extend eastward across the Beltsville Agricultural Research Center lands in northern Prince George’s County through northern Anne Arundel County to the headwaters of the Magothy River. These globally-rare communities of Maryland’s Western Shore are considered ancient outliers of New Jersey Pine Barrens, occurring at the southernmost extent of their range. We will look for the many species of ericads (plants of the Heath Family) that grow in the preserve, as well as associated plants like Chinquapin (Castanea pumila), Pitch Pine (Pinus rigida) and many others. We can also look for acidic seepage communities and enjoy other plants typical of the Coastal Plain. The Greenbelt Forest Preserve was purchased in 2003 by the city of Greenbelt after 16 years of local advocacy to save this remaining section of the original green belt around the city as it was threatened by development plans. As we enter the Greenbelt Preserve we will be walking in the woodlands of Greenbelt Homes (GHI), an experimental community created in 1937 by Franklin D. Roosevelt's New Deal administration, and now a cooperative. At the end of the walk you might enjoy the Greenbelt Farmers Market (closing at 2 pm) at the Roosevelt Center, or visiting the Greenbelt Museum (open 1-4:30 pm).
Leaders: Catherine Plaisant, John Klinovsky, & Damien Ossi
Level of Difficulty: Easy to moderate with gentle climbs but a couple of small stream crossings, logs to step over and possible short slippery sections. Trails are narrow and minimally maintained. Length of walk is 2 to 4 miles depending on the group's speed and interestand will take about 3 hours. There are options for early return if you are comfortable finding your way back on trails by yourself.
Catherine Plaisant and John Klinovsky live at the edge of those woods and have learned the location of a lot of cool plants there. They are self-trained botanists and welcome ID help for more difficult species. Catherine, John, and Damien are Greenbelt residents and the forest is literally their backyard. Damien Ossi is a wildlife biologist with the DC Department of the Environment, President of the Mid-Atlantic Invasive Plant Council, and a long-time resident of Greenbelt. He has led numerous field trips to forests and natural areas throughout the DMV.
ONLINE REGISTRATION IS REQUIRED. Limited to 15 people.

The Humane Gardener Sanctuary welcomes everyone, from butterflies and tree frogs to rabbits and deer. More of an ever-evolving natural habitat than a static garden, the 2.23-acre land is home to dozens of volunteer native grasses, trees and wildflowers that mingle with the many other native plants Nancy and her husband, Will, have added over the years. Once all turf dotted with a few unhelpful species (Bradford pear, barberry, miscanthus), the pesticide-free space is now a many-layered feast and refuge for wildlife. Nonnatives are still a fact of life here, always hovering around the edges, but the balance has shifted and the native plants have gathered strength, now dominating a once barren landscape.
Leader: Nancy Lawson

Leader: Mary Ann Daly, Western Mountains Chapter of MNPS
Description: Around McMahon's Mill, limestone bluffs front the Potomac with little or no land between river and rock. Below the mill, where the towpath juts out over the river, we'll get a close look at the flora of the adjacent bluffs (without having to scale them). We should see some cliff specialists, such as Alumroots and Allegheny Stonecrop, and limestone lovers, such as Aromatic Asters and Fragrant Sumac. Trees include Common Hackberry, Slippery Elm, and Common Juniper, sometimes growing from clefts in sheer rock, alone or with other plants. Staying on the towpath, we'll stroll downstream until about noon, then retrace our steps. Dues to limited parking at McMahon's Mill, we will carpool from the Downsville Ruritan Park. This field trip involves about 2 miles of walking on easy terrain.
Mary Ann Daly is a retired technology specialist and lifelong student of wild plants. Since moving to Washington County in 2017, she's come to appreciate the special ecosystems of the area.
