In the last month, as Saguaro National Park biologists have worked around Manning Camp (~8000') and hiked to and fro, they've encountered ticks. This is the first time they know of that ticks have been reported in the Rincons.
They collected a number of these ticks and are sending them off to the Centers for Disease Control in Atlanta to see if the Rincon ticks carry any of the diseases carried by other Arizona ticks. R parkeri flyer.pdf
Diseases of concern are Rocky Mountain Spotted Fever, which can be fatal, and Rickettsia parkeri rickettsiosis (documented in Santa Cruz County and the Santa Ritas). The bacteria behind the two diseases are different species. The ticks which carry them are also different species. See PDF
