Data presented for each listed species includes: (1) the species' listing status; (2) lead Region; (3) population status; (4) whether or not the species has an approved recovery plan and, if not, whether one will be prepared; (5) the stage of the recovery plan, and (6) the percentage of the species' recovery objective(s) that have been met. The following information will be useful when interpreting the data in table 4.

(1) Species' Listing

The listing status is identified as threatened (T) or endangered (E). If critical habitat (CH) is designated, it is also listed in the table with the species' status.

(2) Lead Region

This indicates which Service Region has the lead responsibility for the species.

(3) Population Status (Pop. Status)

The status of each species is identified as Improving (I), Stable (S), Declining (D), or Uncertain (U) as defined above. Extinct (E) species are those that are believed to be extinct in the wild.

(4) Recovery Plan (Rec. Plan)

This column indicates whether a recovery plan has been developed: Y for yes; N for no; and NA for non-applicable.

(5) Plan Stage

The status of recovery plan development is reported as indicated below.

F = Final-Approved
R = Revision-Approved (a numeral indicates the times revised)
D = Draft - published in the Federal Register
U = Under Development, planned or a draft not yet in Federal Register
RD = Revision-Under Development (a number indicates times revised)
NA = Not Applicable-Exempt

(6) Recovery Achieved

The percentage of species recovery objective(s) achieved is indicated with a value of 1 to 4 as defined below.

1 = 0-25 percent achieved
2 = 26-50 percent achieved
3 = 51-75 percent achieved
4 = 76-100 percent achieved

Recovery Priority as assigned according to species recovery priority system.

A species is assigned a recovery priority from 1 to 18 according to the degree of threats, recovery potential and taxonomic distinctness. In addition, a species' rank may be elevated by adding a C designation to its numerical rank to indicate that there is some degree of conflict between the species' conservation efforts and economic development associated with its recovery. Species with a high priority rank (1, 1C, 2, 2C) are those of most concern with highest potential for recovery. Species with a low rank (16, 17, 18) are of lowest concern or have low recovery potentials.
