This self-paced online module teaches you how to use the Wisconsin Community Tree Map, a compilation of city and township tree inventories from around the state, with your students! With the pursuit of a tree inventory, students can learn more about the trees and forest ecosystems around them, becoming more intimately familiar with the places and spaces in which they live. Using a smart phone or other device, students learn technical skills using equipment and observation, real-world critical literacy, outside field collection, data analysis and interpretation, systems thinking processes, and civic science practices.
