FIRE ECOLOGY

SPECIES: Carnegiea gigantea | Saguaro
FIRE ECOLOGY OR ADAPTATIONS : Saguaro is not truly adapted to fire because there is no postfire stimulation of flowering or seed production [73]. It has several prominent morphological characteristics, however, that may aid its survival when burned. The apex is protected to some degree by tissue folds and spines. Vascular tissue is protected by a thick cortex that has a high thermal capacity close to that of water. As saguaro ages, ribs at the base of a plant may develop a woody bark which is more resistant to burning than young tissue [73]. Although mortally injured by fire, death may be delayed if the saguaro can live off of its reserves, which may enable a plant to flower for 1 to 6 years more [73]. Singed saguaro have been observed to flower from unburned branches. However, scorched plants may die due to reduced vigor [58]. Fire may remove spines from a saguaro, making it vulnerable to herbivory [73]. Nurse plant species influence saguaro fire survival. Although desert fire temperatures are variable, fire temperatures beneath foothills paloverde were lower than under triangleleaf bursage (Ambrosia deltoidea) [16]. Fire-free periods in the Sonoran Desert are greater than 250 years [73]. Saguaro would be eliminated under a fire frequency of less than 30 years [58]. Fires that do occur are usually of low intensity due to small fuel loads [41]. POSTFIRE REGENERATION STRATEGY : Tree without adventitious-bud root crown Secondary colonizer - off-site seed
