Urban Forest Effects Model (UFORE) & i-Tree Eco


The Urban Forest Effects Model (UFORE) is a science-based, peer-reviewed computer model designed to assess and quantify urban forest ecosystem services, based on field data inputs and external datasets (e.g. weather and pollution). It was adapted for inclusion with the i-Tree software suite from the USDA Forest Service, and was subsequently renamed as i-Tree Eco.


UFORE is a compilation of three programs; a field plot selector, a data collection program and the UFORE application, where data can be analysed and exported as tables and graphs. It was developed in the 1990s to help managers and researchers quantify urban forest structure and its functions. The model calculates numerous forest attributes, including species composition, diameter distribution, tree health and species diversity. It allows the user to quantify the effects of trees on air pollution, greenhouse gases and building energy usage. A particularly useful application of the model is to predict the PM10 concentrations before and after green space establishment. The model is available through the i-Tree website (link below), along with user guidance, manuals and case studies.
