If you are using preloaded data, please write to us as info [at] itreetools.org and we'll help troubleshoot the dataset. If you're using your own datasets obtained or modified outside of i-Tree Hydro, we cannot troubleshoot your specific files for you, but the following information may assist you in...

i-Tree Hydro V6 processes timeseries data - weather, evaporation, and observed streamflow - into a comma delimited format. This is intended to make it easier for users to customize their timeseries inputs. Comma delimited data can be copy and pasted into spreadsheet software such as Microsoft Excel,...

An i-Tree installation CD can be created using an ISO Image file available at the i-Tree Desktop Applications Download page: https://www.itreetools.org/tools.php Instructions on how to burn an ISO Image file onto a CD/DVD-ROM are available at: http://knowledge.seagate.com/articles/en_US/FAQ/201431en...

This issue has been resolved in i-Tree Suite v6.1.20. If you have the software already downloaded on your computer, open one of the apps and update through that. For example, open i-Tree Hydro then click on Help drop-down in the top menu bar and select "Check for Updates".

This issue has been resolved in i-Tree Suite v6.1.20. If you have the software already downloaded on your computer, open one of the apps and update through that. For example, open i-Tree Eco then click on update software in the top menu bar.

Preloaded streamflow data selected from a map is not downloading correctly correctly. If starting a project from scratch and downloading streamflow data from the map, you'll get an "Index was out of range" error. If other streamflow data had been provided in the project, the program will use that in...

There are multiple Hydro v5 issues revolving around the parameter q0 (listed in the GUI as 'Annual Average Flow of Project Area') having its default value and range calculated incorrectly by the software. We're converting from Annual Average Flow (m^3/s) in the GUI to specific discharge (m/hr) and s...

Question: How can reduced stormwater flow and pollution be quantified into money saved by a municipality in the northeast USA? Answer: Reduced stormwater flow and pollution is valued in i-Tree as 'net avoided runoff', meaning the amount of surface runoff (and associated pollutants) that no longer n...

This is the depth of the water column which can act as the interface between surface and subsurface flows. The Upper Soil Zone is involved in infiltration, saturation, percolation, and evapotranspiration processes. It represents an average for the entire project area. This parameter describes the ma...

The carbon sequestration, oxygen, and structural value estimates are slightly different after updating to Eco version 6.0.4 due to a change in how tree condition/dieback information is processed. Up to version 6.0.3, the user-defined dieback categories were grouped into 7 standard report dieback cat...

Hi rrds and thanks for your interest in using i-Tree Tools. This is a bug that we've tried to correct in a recent update to the i-Tree Suite. We're still testing this update but so far it is in good shape and it should resolve this issue for you. You can access the update on the i-Tree website by go...

The US Forest Service has processed international UFORE and Eco projects for the past 10 years free of charge as a courtesy. The old manual processing system is not sustainable to meet the increased interest given our limited resources and funding. Although the new system may have more data and time...

We understand and appreciate that i-Tree users have their own project deadlines and many ask us for expedited processing. Since the new system is still in development, we can't accommodate these requests until the system is operational and we address the current backlog of projects.

Users from the USA, UK, AUS, and CAN will be able to use the app to add new species and update pollution and/or precipitation data, but they will not be able to add new locations for the continents. Users in the US territories will be able to input new location, precipitation, pollution, and species...

Due to the current 6-month project backlog, some international users with projects in the processing queue may be directed to use the new system to enter their local hourly pollution, locational information and other data needed for integration and processing. Projects near the front of the queue ma...
