I am researching the topic for a writing assignment and since the most recent comment posted here (1/20/2014 by Myron Smith) the total mortality of the 31 sheep relocated on Catalina has reached 16 total, 14 being prey of mountain lions.
The desert bighorn sheep of the Catalina have been studied and documented since at least 1885. The relocation projects have been considered since 1985 and in 1990 sheep were transplanted on the mountain. In less than ten years all the sheep were considered extirpated.
To Cecil: In regard to your claim of numerous successful sheep transplants- I read in a report that only about 2 sheep reintroduction sites in AZ are actually "successful," while many of the others are barely sustaining a miniscule population.
To Myron: I'm not a English major, however, I noticed Mr.Small only used the word "exponentially" twice in his whole comment to describe the increase in human disturbance and urban encroachment. Considering the timeline Small presented (Mid 60's to Present day) I would agree that over the last 50 some years the growth of human presence in Tucson has increased exponentially. It becomes especially true if you consider the decline of sheep being documented over the last 100+ years.
