Conservation Status and Classification

How vulnerable is a natural community to being eliminated? How similar or dissimilar is it to other natural communities? These questions are answered by naming and classifying natural communities, which helps us identify them and understand where each is found.

The U.S. National Vegetation Classification is the standard often used to classify natural communities.
