SHANKSVILLE — The National Park Service (NPS) and the Friends of Flight 93 hosted volunteers Thursday and Friday during National Volunteer Week. Over two days 150 volunteers contributed hundreds of hours to improve the National Memorial and observe Earth Day.

On Thursday, the NPS hosted the PennDel Chapter of International Society of Arboriculture. Approximately 50 certified arborists joined hands and chainsaws to assist with tree pruning, hazardous tree removal and wood chipping along roadways and scenic views.

“We are excited to continue the tradition of bringing volunteers together and around National Park Week to assist with many projects across the memorial landscape,” said Western Pennsylvania National Parks, Chief of Resource Management Colleen Curry.

The Friends of Flight 93 continue to support the growth of this incredible landscape memorial,” said Donna Gibson, Executive Director of the Friends of Flight 93. “Now that the reforestation project has been completed, the Friends are looking forward to new environmental projects with the National Park Service.”

The Friends of Flight 93 welcomed nearly one hundred volunteers Friday from regional businesses to volunteer at Flight 93 National Memorial. The US Office of Surface Mining, Reclamation, and Enforcement (OSMRE) and Pennsylvania Appalachian Regional Reforestation Initiative (ARRI) assisted with the planting of 1,500 native trees and 625 native shrubs over 3 acres. Native wildflowers grown by the NPS were planted by volunteers to replace non-native grasses on a hillside overlooking the 40 Memorial Groves.
