Urban Ecosystems and Social Dynamics

Urban Ecosystems and Processes

Biometrics

The benefits provided by an urban tree, such as energy conservation and improved air quality, are dependent on the size of the tree. The total value of the benefits a tree can provide are calculated and then projected over a 40-year period, making it important to know how large a tree is likely to grow. Growth equations have only been developed for a limited set number of species, usually pines and firs on forested lands. To lend the values generated by our benefit-cost analyses greater accuracy and applicability, we are developing growth equations for tree species that exist in urban forests throughout the West.
