Background

The UFORE computer model (a.k.a. i-Tree ECO) was developed to help managers and researchers quantify urban forest structure and its functions. UFORE is designed to use standardized field data from randomly located plots, and local hourly air pollution and meteorological data to quantify urban forest structure and numerous urban forest effects for cities across the world. The model calculates numerous attributes about the urban forest, including:

bulleted itemSpecies composition
bulleted itemDiameter distribution 
bulleted itemTree health
bulleted itemSpecies diversity
bulleted itemExotic vs. native species distribution

bulleted itemAir pollution
bulleted itemGreenhouse gases and global warming
bulleted itemBuilding energy use

This model is currently available through i-Tree. The program, which was originally written in SAS, is currently being converted, in cooperation with the Davey Resource Group, to a Windows® based code. New analytic modules are and will be developed in the future, including GIS-based mapping and analysis capabilities.

Field Data Collection Manuals (UFORE manual available at i-Tree)
Presents information of how to establish plots and measure variables that can be used to quantify urban forest structure, functions, and values. Manual for urban FIA (2mb- pdf) plots is complete.
