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...

Unfortunately, there are certain species that are hard-coded into Streets and cannot be deleted. This is one of the limitations of the relatively simple models underlying i-Tree Streets. It needs to maintain species codes that will work for the "other" tree categories. For example Acer rubrum (speci...

Hi Horacio, I have never looked at the exact situation you describe but you may want to run a test where you enter a variety of crown diameters for a couple species and see how the results you are interested in change. Also, you may want to review this document which indicates which results are base...

Hi Hannah, I'll try to answer you questions in order. 1. You do need to submit the data from your mobile device. Once you submit it resides on our server until you retrieve it into your project on your PC. The records do disappear from the web form so that we don't end up with records on our server ...

Hi Pete, Glad you got it straightened out. If I understand what you are trying do, I would probably just create an empty template project with the correct set-up but no data. Then each time you want to create a new project you would open the template project, do a "save a copy" from Eco file menu, r...

Hi Pete, I can't recreate that exact error on my end. Could you create a packed project from the "File" menu in Eco, then send the .zip file that is created to our support email, info@itreetools.org? Also, let me know a few more details: 1. Is this something that happens when you are trying to submi...

Hi Pete, Diversity indices are indeed available in the latest version of i-Tree Eco by going to the "Report" tab and selecting "Composition and Structure">"Diversity Indices">"By Stratum". The diversity indices are only available for plot based projects that use statistical sampling. This is because...
