In November of 2018 i-Tree Eco was adapted for use in a number of European Union countries. This adaptation required the use of a number of local data sources to support the i-Tree models and create localized monetary valuations. Below is a list of the data sources used. Primary/Secondary Partitions...

The i-Tree Eco biomass adjustment factor methods have been updated. The biomass adjustment factor (BAF) is a 0.8 multiplier that gets applied to tree biomass and subsequent carbon storage estimates. The BAF is meant to account for the fact that i-Tree biomass equations are largely from natural fores...

This was a bug in our server side processing. It was introduced as we make preparations to allow users to customize diameter classes. Diameter distributions by strata were not impacted and should be correct in all projects. If you have a project that was submitted for processing between 11/22/18 and...

This one is a little hard to diagnose without seeing the actual data. Would you mind sending your packed project to our support email address, info@itreetools.org? You can create a packed project from the "File" menu in Eco. Also, if you could send along screenshots of the two different reports that...

Our developers also reminded me that they have made some changes to the software to minimize the chances that it gets stopped by antivirus or firewall software. To that end, you should make sure that you are using the latest version of i-Tree Eco by clicking on "software update" under the support me...

Hello, Connectivity issues are very difficult for us to diagnose unless our server is down. There have not been any sporadic server outages in the last few weeks. Typically, these errors are caused by firewall or anti-virus software preventing i-Tree Eco from contacting our servers. These errors can...

Hi Sam, That sounds like a pretty significant undertaking. We don't capture all of the projects that people are using i-Tree Eco for but the biggest one that I am aware of is the Chicago Regional survey, https://www.itreetools.org/resources/reports/Chicago_Region_rb_nrs84.pdf . They reported using 2...

i-Tree should work with the 32-bit version of the database engine. There have been some issues with the default database engine that is installed with enterprise versions of windows. Once you have installed your 32-bit software try opening i-Tree Eco and creating a test project. If the software cras...

Hi Prateek, There are 16 Community Tree Guides, 1 for each of the 16 climate zones on that map. You can find those in the Archives I linked to above, http://www.itreetools.org/resources/archives.php . You will need to expand the "i-Tree Streets & STRATUM Resources" section there and then scroll down...

Hi Hannah, Sorry you are running into this issue. You have not done anything wrong. Unfortunately, this is a bug in Eco at the moment. The bug only impacts users doing plot-based projects and collecting that shrub %. We expect that this will be fixed the next time we release an update for i-Tree Eco...

Thanks for your question. The methods in the GHG Planting Calculator are actually adapted from i-Tree Streets which is a region based empirical model. Essentially, the tool "maps" the entered trees onto trees that were measured in the same climate/growth zone and assumes that these trees would seque...

Hi Lyn, Could you let me know what city you added to the location database? Also if you could let me know the email you used when you submitted your data that would be great. You could PM me or email me at info@itreetools.org with that information. I want to make sure that we have received your info...

You can still have your project processed but first you will need to add your location via i-Tree Database, http://www.itreetools.org/database/#/splash . Once you are on the i-Tree Database website you only need to select the "Add to Database" drop down at the top of the page and choose "Location." ...

Hi Donatien, Usually when we see that error message it is because the i-Tree Eco software does not have access to the live weather data server. In order to allow for that access please make sure the i-Tree Eco has permission to both send and receive information over your network, and through any fir...

Hello, In order for changes that you make to the desktop project to show up on the mobile device please follow these steps. 1. Submit any data you have already collected from your mobile device and retrieve it into you desktop project. If you do not do this any collected data still on your mobile de...
