Research & Maps
Casey Trees has been conducting research on D.C.’s trees since our founding. Using a combination of field work and remote sensing, we produce reports and maps – both paper and in an online interactive format – on the composition, extent and effects of the urban forest. These reports and maps are based on emerging techniques in urban forest measurement and on well-vetted methods for quantifying the benefits of urban trees.
In this role, we provide informational support to advance our planting, design and education programs and those of our cooperators, educate D.C. residents and decision makers, and fuel the study of urban forests.
