This step-by-step guide makes it easy to identify a tree by the kinds of leaves it produces.
Explore a broad variety of hands-on activities on howtosmile.org to learn more about forests and trees. You can use these activities in classrooms, with community groups, or on your own.
And if you really want to get involved, look for a local tree group. Many offer classes and opportunities for active learning.
Phenology — the science of the recurring life cycle stages of plants and animals — is a sensitive indicator of current and future impacts of climate change. You can help researchers by signing up to observe a tree then reporting observations throughout the year. Register at Nature’s Notebook.
