Mobilized by the American Geophysical Union’s Thriving Earth Exchange, a group of scientists have joined forces to address climate change through ‘tree canopy preservation’ in Berwyn Heights, Maryland, United States.
The American Geophysical Union’s Thriving Earth Exchange brings together scientists, community leaders, and sponsors to work toward solving local challenges related to natural resources, climate change, and natural hazards.
Our group of diverse leaders and experts have joined forces to address climate change through tree canopy preservation in Berwyn Heights, Maryland: Lauren Allen, Town Manager of Berwyn Heights; Dr. Amanda Dewey, Mayor of Berwyn Heights; Dr. Jeffrey Warren, Plant Physiologist at Oak Ridge National Laboratory in Tennessee; and Irmarís Rivera-Llavona, Operations Coordinator at EcoExploratorio: Museo de Ciencias de Puerto Rico in San Juan.
Irmarís manages the tree canopy project as part of her role as an ASTC-sponsored Thriving Earth Exchange Community Science Fellow.
Tree canopy preservation project
Our Thriving Earth Exchange project is focused on improving long-term forest canopy health, sustainability, and aesthetics. By removing invasive vines, we hope that the young trees and branches currently covered can recover and grow more leaves, which encourages tree growth, improved vigor, and long-term carbon storage. By also assessing regeneration and promoting new tree planting, we are looking to recruit new trees into the canopy of the future, where they can replace older trees as they progressively age, lose branches, and ultimately die.
Berwyn Heights is using the strengths of community science to find solutions to addressing climate change and preserving our tree canopy. Berwyn Heights is a certified Tree City USA community and has a long history of tree protection. The town recognizes that shade trees can improve quality of life, absorb stormwater, reduce summer temperatures to help save energy, and provide many other benefits. Residents, and specifically the Berwyn Heights Green Team—a residents’ committee focused on advancing sustainability goals—have prioritized the protection of the tree canopy after witnessing declines in the town and neighboring municipalities.
Invasive species, especially vines like English ivy, have been identified as an important threat to the health of trees and contributor to canopy loss. The efforts in Berwyn Heights are unlikely to be successful at preventing further decline of the town’s ecosystems without broad community engagement that reaches all parts of the community. We collected survey data of canopy health and work with private property owners to mitigate invasive species growth, actively engaging community members and enabling the tree canopy to thrive and expand.
Community science makes a difference
A community science approach offers key advantages over traditional, top-down approaches that can unintentionally exclude residents and community members. Involving community members in collecting data and developing solutions includes the lived expertise of community members in the project. Residents have valuable perspectives, knowledge, and relationships that strengthen outcomes and can be overlooked without meaningful engagement. Additionally, involving community members throughout the life of a project can support increased participation and community ownership.
So far, volunteers have conducted surveys that map the extent of damage by invasive vines in the community and took part in an ivy removal demonstration for residents. Next steps include further data collection on regeneration of young trees as well as volunteer removal of ivy and other invasive vines. Perhaps most exciting is the opportunity for residents to request assistance from project volunteers in mitigating vines in their backyards. This can provide support to residents in need and increase community connection between members of the community.
