Trees and MWEEs
History
• Jeff Kirwan• Project Learning Tree• i-Tree
History
What is a MWEE?• Investigative or project oriented• Richly structured and based on
high-quality instructional design• Integral part of the instructional
program• Part of a sustained activity• Consider watershed as a system• Involve external sharing and
communication• Enhanced by natural resources
personnel, community partners• For all students
Community Partners
Logistics for Tree StudyCosts and Materials Minimal Investment• Tree ID books• Tapes• Cameras• Computers
Class Time• 3 Sessions
for Initial Study
When• Late March to October

Day 2 – Our Tree and i-Tree
• Choose and Identify a Tree
• Tree Health Assessment
• Use i-Tree Designhttp://www.itreetools.org/design.php
• Monetize the Tree’sEcosystem Services
Tree Benefitso Stormwater Runoff Reduction
o Energy Consumption
o Air Quality
o CO2 Sequestration
o Wildlife Habitat Value
o Social Value
o Property Value
o Timber Value
1. Where are you? Type in your street address
i-Tree Design in 4 Easy Steps
2. Draw the outline of building of interest (house, school etc)
Add approx. building date
i-Tree Design is a free online tool at www.itreetools.org/design.
3. Add in your tree’s data: - Species - Circumference or diameter - Health condition - Exposure to sunlightPlace your tree on the map
Repeat with other trees
4. Estimate current and future tree benefits
i-Tree Design in 4 Easy Steps
e.g. Dissolved Oxygen Project, at Gunston Middle School

Use i-Tree Design to Assess Impact Value for 1-99 years
• Project Goal includes: Plant 15 Trees along a Potomac Stream Buffer
• Impact Value: $200,000+ benefits over next 99 years• Huge impact, low cost
e.g. Dissolved Oxygen Project at George Washington Middle School
Use i-Tree Design to Budget and Market
e.g. Dissolved Oxygen Project at George Washington Middle School
