Reintroduction was included as a strategy for panther recovery in the original Florida Panther Recovery Plan in 1981 and has been included in all three revisions.

Recovery Objective: to achieve three viable, self‐sustaining panther populations within the historic range.

Page 4: FLORIDA PANTHER REINTRODUCTION FEASIBILITY STUDY › panther... · (lions/ 100 km2) February '93 ‐June '93 1:3 75 0 25 225 1.8 July '93 ‐April '94 1:4 60 0 40 190 2.6 May '94

Accomplishing this Recovery Objective would require  at least 2 additional populations within the historic range.

1. To determine the feasibility of using translocated wild panthers to reestablish Florida panther populations.

2. To evaluate an initial stocking of at least 10 panthers as a means of establishing a panther population in northern Florida.

3. To compare the performance of wild‐caught animals with captive‐raised animals in the initial release.

CONCLUSIONS

• Reestablishment of additional Florida panther populations is biologically feasible.

‐‐ Advantages and disadvantages of both captive‐raised and wild‐caught translocated animals.

• Social problems will have to be solved before reestablishment of additional Florida panther populations is feasible.
