Re: comparing 30yr to 50yr forecast outputs

I was able to replicate that discrepancy due to different project lengths and agree that appears to a bug rather than a rounding error. I have submitted it as an issue through our internal system and our development team will take a look at it. Adding avoided runoff to the Forecast projections is on...

Re: Differences between Ecov6 field manual and program

Thanks for your question. This is a very recent update to i-Tree Eco that has not been documented in the manual. i-Tree Eco previously only used dieback but some users are more comfortable collecting a crown condition percent. Users now have the option collecting either dieback or crown condition du...

Re: How are the benefits calculated?

Hi, I am assuming you are using i-Tree Eco. In that case, most benefits are calculated on a per tree basis. In large part the benefits in Eco depend on the leaf surface area and not the canopy cover. You could potentially extrapolate data measured on some trees to the whole city but you would be mak...

Re: Eco Tree Inventory/Adding Trees

Hello Mauricio, I can't recreate this exact issue but there may be a couple things going on. It is possible that you are trying to import your height data into the "dbh height" field. That field is used for the height at which DBH is measured and is capped at 6.0 m. Alternatively, if you are importi...

Re: iTree Eco "system error" pop-up

Hi Kim, Usually when it stops at 40% it indicates that i-Tree Eco is having trouble connecting to our server. This can happen for a number of reasons. Occasionally, our server goes down. I just tested this (3:00 pm EST 5/30/19) and was able to submit a project without issue. More often it is because...

Re: Import data from Excel to Eco v6.0 in a plot-based sample project?

Yes it is possible to export data from a plot-based sample project to a spreadsheet. In i-Tree Eco you would click on the data tab, then select the "Plots" button. With the "Plots" table open you can then click on the "CSV" button to save a spreadsheet that can be opened in MS Excel. You would then ...

Re: How does i-Tree Eco simulate leaf area fluctuation in leaf-in/ leaf-off season ?

Thanks for your question. The leaf on/off parameter is a location specific parameter. For any location a user can select in i-Tree Eco the underlying database has average leaf-on and leaf-off days. In the US these dates were estimated based on frost free days while in other countries they may be pro...

Re: I'm using I Tree Eco and when I try to submit my data for processing I get the message "FTP Upload Failed."

Hello, Sorry to hear about this issue. This can be a little hard to diagnose but my first two thoughts would be: 1. Occasionally, we will have server outages. In those cases mean i-Tree Eco on your computer can't communicate with outrFTP server. I haven't seen any recent records of outages and was j...

Re: Import data from Excel to Eco v6.0 in a plot-based sample project?

Hello, Unfortunately, import of plot data is still not possible. Unfortunately, that feature is challenging to build because it requires the import of two linked tables (plots and trees) with significant error checking to ensure that data is compatible with i-Tree Eco. At the same time relatively fe...

Re: MyTree: calculation for total benefits this year

Hi Susanne, The benefits are meant to be representative of this calendar year (currently 2019). They aren't really per year because next year the tree will be larger and presumably providing more benefits. They also aren't to-date, but represent an estimate of the benefits as the tree grows new leav...

Re: How do I add new species in Eco for a UK project

Additionally, if you are only adding a few species you can submit them through i-Tree Database, https://www.itreetools.org/database/ . Use the "Add to Database" drop down at the top of that webpage. Accepted species will be permanently added to i-Tree Eco the next time a software update is released....

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.

The BAF is meant to account for the fact that i-Tree biomass equations are largely from natural fores...
