i-Tree Unit Lesson 6: Tree Adaptations

In Lesson 5: Canopy Assessment, students subtracted the annual amount of sequestered carbon dioxide from the carbon footprint of their zip code. This gave them an understanding of the “carbon balance” of their zip code, or the amount of carbon that is possible to capture by planting additional trees. In Lesson 6, students will examine which tree species are best suited for their area based on two factors that affect tree adaptations: precipitation and temperature.
