Navigating the Application
In the six inventories we've done using i-Tree
Eco version 6 (Table 1), we used both paper and
the i-Tree web application to gather the data.
By the time we inventoried trees in Puebla in
October of 2018, a Spanish-language version of
Eco had been released. Interestingly, however,
we had by that time found that we were accus-
tomed to gathering i-Tree data in English.
Some of the parameters that require previous
experience to evaluate, like crown condition
and specific maintenance recommendations,
were initially a challenge for some of the less
experienced surveyors. However, with the
help of the web application, we were able
to refine data collection and ensure that the
data was gathered correctly. The GPS coordi-
nates provided by i-Tree Eco were invaluable.
To document findings, I've written inventory
reports that can be seen on the i-Tree website,
and I presented at the First International
Congress of Public Parks held in Mérida in
April 2018. Some inventories were of the
public trees of entire municipalities in their full
hectares/acreage, while others were inven-
tories of trees in specific parks, using either
a sample or the complete population.
