i-Tree Eco

i-Tree Eco v6 overview

i-Tree Eco version 6 is a flexible software application designed to use data collected in the field from single trees, complete inventories, or randomly located plots throughout a study area along with local hourly air pollution and meteorological data to quantify forest structure, environmental effects, and value to communities.

  • Avian habitat suitability (plot-based projects; limited to 9 bird species) Avian_Habitat_Suitability_report_example.pdf
  • Ultraviolet radiation (UV) tree effects UV_Report_Ecov6_example.pdf

Structure and composition analyses:

  • Species condition and distribution
  • Leaf area and biomass
  • Species importance values
  • Diversity indices and relative performance

Forecasting modeling options including:

  • Tree planting inputs
  • Extreme event impacts for weather and pests
  • Annual mortality adjustments

Management information including:

  • Pest risk analysis
  • User defined optional fields
  • Cost benefit analysis

Eco Report Examples - Springfield MA Squares

These are examples of exported structural, benefit analyses, individual level PDF reports from a demonstration project applying Eco to (2) small public squares. You will not need Eco installed to view examples of these reports.

Who is using Eco?

Thousands of people in the United States and internationally have used Eco for projects ranging from small tree inventories to regional scale assessments. Eco users include government agencies, consultants, nonprofits, universities, researchers, volunteers, educators, advocates and more.

Choose your project type

Complete Inventory - Typically used for smaller public areas or private properties such as corporate campuses, parks, apartment complexes, individual homes or cemeteries. Learn more

Sample Inventory - Used when the study area is too large to cost-effectively inventory the entire tree population. Project estimates and benefits are based on sampling of random plots. Learn more

Learning resources

Manuals and Guides - Provide step-by-step instructions for all project phases. New guides offer detailed information on specific topics. Learn more

Video Learning - New instructional videos are being developed to show you how to use the Eco v6 application. Learn more

Model Methods, Technical Papers and Journal Articles - Explain the background model science, processes and limitations. See the Archives Eco v6 sections. Learn more

International Eco users

Adapted for Canada, Australia, the United Kingdom, Mexico, and the European Union. Eco v6 has been adapted for use throughout Canada, Australia, the United Kingdom, Mexico, and the European Union with pollution and weather data pre-processed and available in the application.

Processing for other international Eco users - International projects completed in countries other than those listed above will require using the new i-Tree Database system. In an effort to accommodate growing international interest, we are transitioning to this new system that will help automate processing and allow users to have their new international locations incorporated into a future version of Eco.

  • i-Tree Database - Online system to add data for new, previously unsupported project areas outside the countries listed above.
  • Ecov6Guide to International Projects - Formal guide for international projects outside the countries listed above. This guide can be used for reference while it is being updated for the new i-Tree Database system. Learn more

Eco v5 - Eco v6 considerations

You will find the Eco v5 legacy application available within the i-Tree 2016 suite for users currently working on an Eco v5 project. Or, who require using the old PDA utility for data collection. Version 5 projects can be opened in Eco v6 and updated but will require reprocessing for reports to be updated.
