Figure 2.1. Location of the two districts of Saguaro National Park in southern Arizona. Average annual temperatures for low elevations from 2001 to 2003 were above the long-term mean of 21.3 o C (21.5 o C in 2001, 21.6 o C in 2002 and 22.0 o C in 2003; Fig 2.3; WRCC 2005). Average annual temperatures for high elevations ranged from slightly below to slightly above the long-term mean of 8.5 o C (6. o C in 2001, .3 o C in 2002 and 9.5 o C in 2003; Fig 2.3; PCFCD 2005), though these records have only been kept for 10 years. 8 Vegetation and Biotic Communities The Rincon Mountain District encompasses most of the Rincon Mountains, one of the “sky island” mountain ranges of southeast Arizona and northern Mexico. Sky islands, so called because the “sky” mountains are isolated by “seas” of desert and semi-desert grasslands, are areas of remarkable biological diversity as a result of elevational gradients and subsequent
