Ecobenefits of National Capital Region Park Trees
Dedicated to preserving parks for future generations, the National Park Service collects long-term data on a variety of resources including trees. Scientists within NPS have evaluated the data for forest structure trends. The iTrees suite of tools presents an opportunity to quantify benefits.
Katherine Ferguson, recent MLA graduate, collaborated with the Urban Ecology Research Learning Alliance (UERLA - the regional Research Learning Center of the National Capital area of the National Park Service) to evaluate NPS data using iTrees tools. Her research brief, Ecobenefits of National Capital Region Park Trees, is the first in a series to describe tree benefits across the region.
