What is i-Tree Eco?
• Forest assessment and valuation
tool using sample or complete
inventory field data
• Originally developed for assessing
whole urban forest
• Reports structure, function,
benefits, and value
• Includes forecasting component
• Flagship software based on latest
science & local data

14. i-Tree is a
Cooperative
Initiative among
• Governments
• Non profit organizations
• Universities & campuses
• Parks and public gardens
• International users
• Consultants
• Researchers
• Corporations and institutions
interested in sustainability
• Innovators – creating interactive
maps, tree trails and their own tools
using Eco
Who is using Eco?

16. i-Tree is a
Cooperative
Initiative among
The basic science
• Measured variables to
estimate foliage volume
and wood volume
• Estimates tree leaf area
using species specific
equations
• Estimated benefits
largely based on leaf
area interactions with
local weather and air
pollution
• Summarize structure,
function, value

Eco tree data variables
1. Tree species
2. Diameter at breast height (DBH)
3. Total tree height
4. Height to live top
5. Height to crown base
6. Crown width (N-S & E-W)
7. % Crown missing
8. % dieback (condition)
9. Crown light exposure (CLE)
10. Direction to building (Energy effect)
11. Distance to building (Energy effect)
12. Land use

i-Tree Eco vs i-Tree Streets
Streets (legacy)
• Management tasks
• Return on investment
• Individual tree inventory
• Map coordinates
• Street segment sampling
• Planting opportunities
• Add species on the fly
• Dated regional science
Eco
• Management tasks
• Return on investment
• Individual tree inventory
• Map coordinates
• Street segment sampling
• Planting opportunities
• Add species on the fly
• Dated regional science
• Localized with the latest science

24. i-Tree is a
Cooperative
Initiative among
i-Tree Eco: Advantages
• Local Modeling – Eco uses local
hourly pollution, weather data and
other local characteristics for
modeling
• Dynamic tool – constantly improved
with new science, international
locations, reports and functions
• Flexible data collection and project
design options make Eco accessible
to more people
• The Eco import option is a great way
to assess existing tree inventory data
quickly

25. i-Tree is a
Cooperative
Initiative among
i-Tree Eco: Advantages
• Eco is designed to address the
“All Lands and All People” USFS
objective.
• Eco offers users options to
improve the model. e.g. adding
new species, hourly rainfall
data, biomass equations
• Flexible results – Eco reports by
species, strata and individual
tree to help with strategic
decision making.

26. i-Tree is a
Cooperative
Initiative among
i-Tree Eco: Limitations
• Time – complex, large projects may require significant
resources
• Most accurate results requires more data collection
variables. e.g. crown measurements
• Amount of results and reports can make it challenging
to find impactful or important results
• Local data may not be available or complete for all
locations, and not representative of actual conditions
• Spatial limitations - Eco can’t model spatial variability
• Application requirements – Eco needs to send and
receive data over the internet
• Not an asset management tool
• Steep learning curve

27. i-Tree is a
Cooperative
Initiative among
i-Tree Eco: In Development
• Change analysis
• Update carbon equations
• Update values and input data
• Integration with FIA/UFIA
• New international capabilities
