i-TREE LESSONS
In 2006, Davey partnered with Casey Trees, USDA Forest Service, Arbor Day
Foundation, Society of Municipal Arborists and the International Society of
Arboriculture to develop a software suite designed to analyze urban forests
to assess the benefits trees provide. The i-Tree software has helped countless
communities and organizations quantify the value and structure of trees. Now,
i-Tree Lessons is expanding the audience to school-age children. In continued
partnership with Casey Trees, Davey is helping develop a new, science-focused
curriculum for middle school students based on i-Tree. The i-Tree Lessons
curriculum, which is outlined on itreelessons.com, explores the concepts of
forest inventory, assessment and use of i-Tree Tools to satisfy requirements
of the Next Generation Science Standards for middle school students.
The goal of i-Tree Lessons is for students to use i-Tree software to design a
possible solution to a real world, place-based problem: increased atmospheric
carbon dioxide contributing to climate change. By educating the clients of
the future, Davey hopes to demonstrate the value of high-quality tree care,
increasing preservation and stewardship.
