Thanks for the question. The tree ID field in Eco is actually used by the program to keep track of trees and therefore has some specific database related requirements including sequential numbering. For users that have their own ID field we recently added the "User Tree ID" field. You can turn on th...

Hi Christian, There could be a few things going on here. Here are the first tw0 things I would look at. 1. Make sure that the "land use" field is selected under your "Data Collection Options". You can check those options by going to the "Project Configuration" tab, selecting "Project Definition" the...

Hi Jared, Unfortunately there is no way to account for species directly with i-Tree Canopy. When you select a county during project set-up the underlying models do use local mixes of percent deciduous and evergreen in the estimates of air pollution, (see methods here, https://www.itreetools.org/docu...

UPDATE: Those links have been restored. Occasionally, firewalls or internet browser settings may prevent their download and installation. In those cases you may want to try copying and pasting the URL directly into your web browser. Unfortunately, we generally cannot resolve issues caused by outside...

These calculations aren't included in the i-Tree tools but there is some life-cycle analysis out there that might be relevant. You could start with this paper, https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=13&ved=2ahUKEwjYxobM5tjnAhX6hHIEHe33DywQFjAMegQIBBAB&url=https%3A%2F%2Fwww.fs....

We are looking into having those links fixed or the files reposted. Anson, I am not sure I have ever seen that "pending" issue you mentioned. If you are on a government, university, or other controlled network it may be some firewall setting preventing the installation. If that is the case you may n...

Hi Valeria, Sorry you are having trouble with the project name. If you are unable to edit your project name when you click on the "Project Definition" button under the "Project Configuration" tab you may need to turn the "Editing mode" to "On". The editing mode on/off button is on the right hand sid...

Sorry to hear you are having issues with import. This may be tough to diagnose without seeing your data. One issue that we occasionally see with import is that the wizard doesn't function well if the file being imported is open in other software. Please make sure that your spreadsheet is not open in...

i-Tree Eco projects are usually processed within an hour. Very large projects (greater than 10,000 trees with a number strata) can take longer. The other variable that can make projects take longer is if there are additional projects in the queue ahead of yours. Once you submit your project your you...

Unfortunately we don't have general equations for average benefits by species. To see more about how the underlying models in i-Tree Eco work please see these documents, http://www.itreetools.org/eco/resources/iTree_Eco_Dry_Deposition_Model_Descriptions.pdf and http://www.itreetools.org/eco/resource...

Hi Will, Unfortunately, there isn't a built in mechanism to facilitate the type of batch runs you are describing. As an alternative you could set up each of your projects as a separate stratum and combine them all in one project. Then you could use the individual tree or strata level results in your...

Hi Amy, Those warnings have to do with how i-Tree Eco manages retrieving data from mobile devices. Typically, you get those messages if some change has been made to the data on more than once before retrieval. For example you may have had multiple people submit data from mobile for the same plot or ...

Hello Giacomo, Copice is not a common practice here in the US so i-Tree doesn't have a defined way to handle those trees. However, for multi-stem trees you can enter up to the 6 largest stems as DBH1 to DBH6. Alternatively, you could calculate the dbh of a tree that would have the same basal area as...

Hello, I am not sure that I completely understand your question. There is no certification process for data collectors as the tools are free to use and anyone can use them to collect their own data. The results obtained from the i-Tree tools represent the outcomes of scientific models. Users can rev...

Hello Giacomo, That paper references this document, Nowak, D.J. 1994b. Atmospheric carbon dioxide reduction by Chicago’s urban forest. In: McPherson, E.G.; Nowak, D.J.; Rowntree, R.A., eds. Chicago's urban forest ecosystem: results of the Chicago Urban Forest Climate Project. Gen. Tech. Rep. NE-186....
