As the world becomes increasingly urban, the need to
quantify the effect of trees in urban environments on
energy usage, air pollution, local climate and nutrient
run-off has increased. By identifying, quantifying and
valuing the ecological activity that provides services in
urban areas, stronger policies and improved quality of
life for urban residents can be obtained. Here we focus
on two radically different models that can be used to
characterize urban forests. The i-Tree Eco model
(formerly UFORE model) quantifies ecosystem services
(e.g., air pollution removal, carbon storage) and values
derived from urban trees based on field measurements of
trees and local ancillary data sets. Biome-BGC (Biome
BioGeoChemistry) is used to simulate the fluxes and
storage of carbon, water, and nitrogen in natural
environments. This paper compares i-Tree Eco's methods to
those of Biome-BGC, which estimates the fluxes and
storage of energy, carbon, water and nitrogen for
vegetation and soil components of the ecosystem. We
describe the two models and their differences in the way
they calculate similar properties, with a focus on carbon
and nitrogen. Finally, we discuss the implications of
further integration of these two communities for land
managers such as those in Maryland.
