EAB Quarantine in D.C.

Projects illustrate perils facing D.C.'s trees

T

his summer, the Geographic Resources (GR) department at Casey Trees was busy with projects and data collection aimed at advancing understanding of the composition, structure, and function of the District’s urban forest. The GR team continued the study of young urban tree mortality, worked on a survey of power lines and wires and acquired satellite and aerial imagery for a continuing analysis of changes in the D.C.’s tree canopy.

TREE MORTALITY STUDY For the first study, students in statistics and plant biology from the University of Maryland, College Park and Georgetown University have worked to analyze the relationship between various environmental factors and tree mortality under the direction of their advisors. They will use Casey Trees’ detailed planting

records as a basis for their analysis.

TREES AND WIRES The second project focused on how the ecosystem services and aesthetic benefits of trees are affected by power lines and wires.

UPDATED IMAGERY The new data will help the GR team develop a more advanced understanding of the temporal and spatial changes in the District’s tree canopy as seen from the sky. Results and summaries of both studies will be available online in the coming months. The GR department is responsible for Casey Trees’ online tree tools, such as the Casey Trees Map, D.C. Street Tree Map and the Tree Benefits Calculator.

Last month The Leaflet featured an article about the Emerald ash borer (EAB) quarantine in Maryland and how it could affect the District’s ash trees. On Aug. 10, the USDA issued an EAB quarantine for D.C. The USDA has created a website with information on how to identify and control EAB on your property.
