populations. All 4 desert bighorn sheep populations
in Colorado originated from translocations from outof-state.
Three of these populations have provided
hunting opportunities and have been moderately
successful.
The remaining 14 releases are single group releases
with a wide range of apparent outcomes: the current

population estimate for Trinchera Peak (S51) is 250
animals, but in the Lower Poudre Canyon and Seaman
Reservoir releases there are only an estimated 20
animals remaining. Insufficient data are available to
assess the status of the other releases.
