Epidermal browning and population structure of giant saguaro cactus in Saguaro National Monument, Arizona
Duriscoe DM and Graban SL. 1991. Epidermal browning and population structure of giant saguaro cactus in Saguaro National Monument, Arizona. Eridanus Resarch Associates. Three Rivers, CA
Study plots in both units of Saguaro National Park showed that browning of saguaro skin is prevalent, and does not follow any pattern of distribution. The fact that browning is more severe on the sunny sides indicates exacerbation of the condition by sunlight. Healthier (greener) plants were found associated with mesquite, i.e.in moister areas, and saguaros with browning were more often in drier areas. An encouraging recruitment of young saguaros was found in the Cactus Forest. Brief bibliography, 12 figures, 1 table, 2 appendices (including a list of attachments: see NRBIB: SAGU-0630).
