Recovery Criteria to the Recovery Plan for Three Endangered Species Endemic to Antioch Dunes, California

This document proposes draft recovery criteria for Lange’s metalmark butterfly (Apodemia mormo langei; Lange’s metalmark), Oenothera deltoides subsp. howellii (Antioch Dunes evening-primrose), and Erysimum capitatum var. angustatum (Contra Costa wallflower) that will be made available to the public for review and comment. The intent of the draft recovery criteria is to establish objective, measurable criteria which, when met, would result in determinations for downlisting and delisting of Lange’s metalmark, O.d. subsp. howellii, and E.c. var. angustatum.
