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....

Hello Giacomo, This may depend on which of the i-Tree Tools you are using. If you are using i-Tree Eco please see the section of this paper, http://www.itreetools.org/eco/resources/UFORE%20Methods.pdf , titled "UFORE-C: Carbon Storage and Annual Sequestration". i-Tree is not using species specific g...

Hi Aaron, I could see i-Tree Design being challenging for some users. As an alternative you could try MyTree ( https://mytree.itreetools.org/#/ ) which is even simpler to use. You could also try to putting together some sort of matrix or table of common species and their relative numbers needed usin...

Thanks for the question. i-Tree Forecast is actually a cohort model not an individual tree model which is why it doesn't generate the exact output you are looking for. That being said, you may have some options. One option is to use the "Cohort data output" option when you run Forecast. This output ...

Yes this is still the case. Given our limited staff and development time I don't believe this will be implemented in the near future without a dedicated funding source for this specific feature. Depending on what results you are interested in and your desired accuracy you could always import your da...

This depends on the goals of your project. If you keep them as separate strata in a single project you will have all of your data and results collected in one place. You will also notice that many of the reports have breakdowns by strata which would allow you to compare the different properties. How...

The Energy savings in i-Tree Eco will work without the crown measurements. However, you do need to enable the "Energy (building interactions) option under "Data Collection Options" during project set up and you do need to collect measurements of the distance and direction to residential structures 2...

Thanks for the question, it is a good one. At the moment only results, not unprocessed data, can be mapped within the i-Tree Eco application. After you have submitted your data for processing and retrieved your results please follow these steps to view your data on a map in i-Tree Eco. 1. Go to the ...

Thanks for the question. The i-Tree Eco list currently includes more than 8,000 species, https://www.itreetools.org/documents/488/EcoSpeciesList_20July2018_esxmUKb.xlsx . It has pretty good coverage for most species in the US but may be missing some international species and some tropical species. I...
