  • The Nature Conservancy's Mary Travaglini and Jamie Weaver have dedicated a collective 10 years to protecting and restoring the exceptional natural resources and biological diversity of the Potomac Gorge.
  • Mary Travaglini started working for the Conservancy in Fall 2004 and has led efforts to mobilize hundreds of volunteers from Bear Island to Chain Bridge Flats, including park and partner land in MD, VA, and DC.
  • Here, Mary wields a chainsaw to convert a fallen tree into a replacement trail bridge, providing passage over a stream and preventing trail widening and habitat destruction by people trying to get over the wet areas.
  • Jamie Weaver started working in the 10,000-acre Potomac Gorge conservation area three years ago. His first day of work was — fittingly — on Earth Day.
  • Each year, hundreds of thousands of outdoors enthusiasts flock to the Gorge.
  • To mitigate the impacts of such heavy recreational use, the Conservancy has promoted “Leave No Trace” – like encouraging visitors to use the boot brush (above) to help control the spread of invasives.
  • Invasive species are one of the greatest threats to the rare plants and natural communities of the Gorge. Jamie, Mary, and an NPS volunteer pose with bags of the invasive weed garlic mustard at Carderock Recreation Area.
  • Former restoration intern Adam Samples and Jamie Weaver put their muscles to work by removing a downed Bradford pear, an invasive tree species, from the Carderock Naval Facility in the Potomac Gorge.
  • Thank you, Mary and Jamie for your dedicated work to habitat restoration, volunteer engagement, and public education and outreach work in the Potomac Gorge!
