TUCSON (KGUN9-TV) - Arizona Game and Fish Department is asking hikers to not bring domestic sheep or goats into the Santa Catalina Mountains.
The Catalinas, specifically Pusch Ridge, are the site of an ongoing reintroduction effort for native desert bighorn sheep.
AZGFD volunteers installed signs Friday at the Pima Canyon, Finger Rock and Ventana Canyon trailheads.
AZGFD officials say domestic sheep and goats can transfer disease to wild bighorn sheep. Any disease transfer could have a serious negative impact on the bighorn sheep population.
