The United Plant Savers (UpS) “At Risk” and “To Watch” Lists

United Plant Savers is a nonprofit organization dedicated to the protection and conservation of North American medicinal plants. Periodically the organization publishes two lists of medicinal plants that need help and attention.

The plants in the first list, “At Risk,” are broadly used in commerce and are at risk of significant decline in numbers in their current range. Reasons for their decline may be overharvest or loss of habitat, and/or their rareness or sensitivity.

Plants on the second list, “To Watch,” have been proposed for the “at risk” list, but further research is needed before they are included. So for now they are being “watched.”
