Recent Actions:  On May 5, 1986, we listed Jones cycladenia as threatened rangewide (51 FR 16526). On December 30, 2008, we completed a recovery outline.  This document lays out a basic background on Jones cycladenia and preliminary course of actions for recovery. It serves to guide recovery efforts and inform consultation and permitting activities until a comprehensive recovery plan for the species has been finalized and approved.
