Identifying Trees and Their Features

The video tutorial by Truckee Meadows Parks Foundation covers tree identification and why leaves change color. It explains the role of pigments like chlorophyll, carotenoids, and anthocyanins in leaf color change during autumn. The tutorial also discusses methods for identifying trees using field guides, apps, and dichotomous keys, focusing on the characteristics of coniferous and deciduous trees.
