Twenty bighorn sheep โ€” transplants from mountains near Yuma โ€” bounded out of a transport truck and into the Catalina Mountains early Tuesday morning.

It was the fourth relocation of bighorns in as many years, part of an ongoing effort to rebuild a herd that disappeared from the Catalinas north of Tucson in the 1990s.

โ€œWe brought in 20 sheep from the Plomosa Mountains โ€” 15 ewes and five rams,โ€ said Mark Hart, spokesman for the Arizona Game and Fish Department. โ€œWe now have 85 bighorn sheep in the Catalina Mountains.

โ€œIt was a very successful capture and release operation,โ€ Hart said. โ€œNow itโ€™s up to the bighorns.โ€

The fleet-footed animals leaped from the truck when doors were opened and dashed past wildlife officers, reporters and photographers โ€” heading toward the Pusch Ridge habitat where sheep from the previous relocations roam.

Brian Dolan, a past president of the Arizona Desert Bighorn Sheep Society and a member of a citizens advisory committee on the Catalina bighorn project, watched Tuesdayโ€™s release and nodded with satisfaction as the animals headed for their new home.

PASSIVE MANAGEMENT

โ€œWeโ€™re going to take a more passive approach to managing the bighorns in the future,โ€ Hart said. โ€œSpecifically, weโ€™re no longer going to actively pursue mountain lions that prey on bighorn sheep.โ€

In earlier stages of the project, a total of eight mountain lions were killed for preying on bighorns. The lion killings drew strong opposition from many citizens who maintained that itโ€™s wrong to kill lions for doing what predators do naturally to survive and feed their young.

โ€œThe first phase of the project is a success based on todayโ€™s release,โ€ Hart said. โ€œWith 85 sheep on the mountain, that can be viable moving foreword without active management.โ€
