Reintroduction of Desert Bighorn Sheep into the Santa Catalina Mountains – 2012 – Very similar to the 2011 document below but more information on exact plans and cost as this project appears to be moving forward.

Reintroducing Bighorn Sheep into the Catalinas by Jim Gressinger, Dec. 03, 2012 – A Tucson Citizen article about the efforts to begin the reintroduction of Bighorn Sheep in the Santa Catalina Mountains in 2013.

Restoration of Bighorn Sheep in the Santa Catalina Mountains 2011 – An Arizona Game and Fish Proposal that happens to be the most interesting and complete summary I have ever seen of Bighorn Sheep in the Santa Catalina Mountains – if nothing else this is worth downloading for the picture of 20+ sheep together in the Santa Catalina Mountains!

Catalina bighorns are gone, but explanatory signs live on – Plaques to stay in event species in reintroduced – Interesting, but very short, Arizona Daily Star article from Feb. 2010 – notable because ‘Jim Heffelfinger, a spokesman for the Arizona Game and Fish Department’ gives some comments about sightings (I may not know where to look/who/how to ask but have found that ‘official’ information is somewhat hard to come by).
