This paper is an organized summary discussion of the basic considerations (criteria) used by state-level organizations in determining the status of native taxa on an individual basis (such as endangered, threatened, extinct, or other lesser rankings). First, I discuss general criteria used when classifying plant species and then I highlight seven categories used for ranking plant status in the United States.
