Dendrology is a branch of botany that focuses specifically on the study of trees, shrubs, and other woody plants, including their classification, identification, and characteristics.

What is the term for the uppermost layer of a forest, formed by the crowns of mature trees, which receives the most sunlight?

The canopy is the highest layer of vegetation in a forest, formed by the collective crowns of mature trees, and is where most sunlight is intercepted.

Which tree species is a primary source of maple syrup?

Sugar maples (Acer saccharum) are the most commonly tapped trees for producing maple syrup due to their high sugar content in sap.

What is the primary role of mycorrhizal fungi in a forest ecosystem?
