FIRE EFFECTS
SPECIES: Alnus incana ssp. tenuifolia | Thinleaf Alder 



IMMEDIATE FIRE EFFECT ON PLANT : 

Severe fires can completely remove organic soil layers, leaving alder
roots exposed and charred and thus eliminating basal sprouting.  Low
severity fires kill only aboveground plant parts [19,31,59].


DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 
NO-ENTRY


PLANT RESPONSE TO FIRE : 
Thinleaf alder often sprouts from its root crown following fire.
Several new sprouts may arise from each burned plant, thus increasing
stand density [4,5].

Off-site plants are important in revegetating burned areas through the
dispersal of numerous wind- and water-transported seeds.  Since thinleaf
alder disperses its seeds in the fall, favorable seedbeds created by
late summer fires are immediately colonized [59].


DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : 
NO-ENTRY


FIRE MANAGEMENT CONSIDERATIONS : 
Riparian areas in which thinleaf alder occurs can serve as natural fire
breaks [4,5].
