i-Tree International

What countries can i-Tree Tools be used in?

i-Tree Eco is adapted for use in Canada, Australia, and the United Kingdom, and i-Tree Hydro is in the process of being adapted for wider use beyond the United States. Projects in countries that i-Tree Tools have been adapted for can be processed automatically through i-Tree software without delay.

Countries other than the United States and those listed above are considered 'international' and require additional steps for project processing.

For more information, please see Forum FAQ: Which i-Tree Tools can be used internationally?

Can i-Tree Tools be fully adapted for use in additional countries?

Yes, we have the capacity to adapt i-Tree Tools for use in additional countries, but there is a cost associated with that. If you are interested in expanding i-Tree Tools to work automatically in a country, please let us know by emailing info@itreetools.org.

Overview of International i-Tree Usage

i-Tree Database snapshot

International projects have had additional data requirements and limitations in the past. This includes manual processing of international i-Tree Eco projects, and of international weather data in i-Tree Hydro, done by the i-Tree Team. Due to growing demand, we're no longer able to process international data manually. Instead, we are developing i-Tree Database, a utility which will allow users to submit data for their project area that will then be validated and included in our i-Tree Tool databases, enabling that project area to run in certain i-Tree Tools.

For more information, please see the key points about i-Tree Database and important links below.

Key Points about i-Tree Database

  1. i-Tree Eco and Hydro projects were processed manually by the US Forest Service as a courtesy in the past, but that is no longer possible due to increases in demand.
  2. i-Tree Database enables international users to enter data necessary for running a project in a given area. Necessary data should be entered into i-Tree Database as early as possible for users setting up projects in international areas which can't already be processed automatically.
  3. The US Forest Service will validate data submitted through i-Tree Database and will load valid data into i-Tree's databases, to be updated for users with the following i-Tree Update. Invalid data will be returned to sender for correction.
  4. Once data for a project area has been validated and loaded into i-Tree Tools, users can run projects in that area without delays. As i-Tree Database is used, a list will be updated indicating what areas are entered into i-Tree and are ready for project processing.

Important Links


  • Forum FAQ: Which i-Tree Tools can be used internationally?
  • This post on the i-Tree Support Forum is a good starting point for international users as it provides an overview of which i-Tree Tools can be used internationally and what additional requirements or limitations are involved.

  • i-Tree Database
  • i-Tree Database is a new system in development that will validate and accept international pollution data, hourly precipitation data, location details, new species information, and other model requirements. Data submitted through this system will be vetted and integrated into the Eco model - and potentially other i-Tree Tools - as a new international location that would be available for automated processing in a future Eco update.
