FIRE ECOLOGY OR ADAPTATIONS
POSTFIRE REGENERATION STRATEGY

FIRE ECOLOGY OR ADAPTATIONS:

Fire adaptations: Fremont cottonwood sprouts after fire or other injury. Coppice sprouting is the predominant mechanism of vegetative reproduction in most areas. However, root suckering is the predominant method in some areas of Utah [34,70,79,91,145].

Disturbances such as fire may favor seedling regeneration. Fire thins the overstory and surrounding vegetation, allowing light to penetrate, and exposes mineral soil [143].

Fire regimes: Fremont cottonwoods are not fire dependent [145]. Historical fire regimes for Fremont cottonwood-dominated riparian zones bordering drier ecosystems are poorly described [154]. Fire scars are rare on Fremont cottonwood and when found, usually have such extensive heartrot that the tree's fire history cannot be reconstructed [146,147].Wildland fires appear to have been infrequent in riparian communities dominated by Fremont cottonwood, Goodding willow, and mesquite species prior to invasion by saltcedar [34]. Fire regimes for plant communities and ecosystems bordering Fremont cottonwood communities are summarized below. For further information regarding fire regimes and fire ecology of communities and ecosystems where Fremont cottonwood is found, see the `Fire Ecology and Adaptations' section of the FEIS species summary for the plant community or ecosystem dominants listed below.
