Plants and Animals

The A.T. Seasons program is focused on monitoring plants and animals that have large geographic ranges and are relatively common along the Trail. Our Primary species are those which we will compare trail-wide, while our Secondary species will only be used for local projects.  Click on the links below to learn more about each of these species in Nature's Notebook.
