Neither recovery plan includes recovery criteria. 2.2.2 Adequacy of recovery criteria 2.2.2.1 Do the recovery criteria reflect the best available and most up-to date information on the biology of the species and its habitat? N/A 2.2.3 List the recovery criteria as they appear in the recovery plan, and discuss how each criterion has or has not been met, citing information: The recovery plans for both species state: The criteria for downlisting and/or delisting … have not as yet been determined. Implementing studies in this recovery plan will provide the necessary data from which quantification of downlisting and/or delisting criteria can be established. The plans do include virtually identical step-down outlines of recovery actions. The actions that have been implemented are indicated with an asterisk (*) in the list. The step-down outline for E. v. davisii is as follows:
