FIRE ECOLOGY
SPECIES: Arctostaphylos uva-ursi | Bearberry
FIRE ECOLOGY OR ADAPTATIONS :
Bearberry is a sprouting species that is best suited to short fire
cycles with low fuel buildup and low fire intensities [65,76,114,122].
It possesses latent buds on the horizontal stems and dormant buds on the
stembase or root crown that allow sprouting of surviving plants or
rooted stems [22,23,39,85]. In northern Saskatchewan, it is a strong
sprouter from golfball-sized lignotubers located in mineral soil [114].
The crown of bearberry plants may lie just below the top of mineral
soil, but as duff increases it migrates into the duff layer and becomes
susceptible to fire [14,92,114]. Bearberry's main roots extend into
mineral soil, but it has been considered to be incapable of regeneration
from the roots if the crown is killed [81,92]. Since it can be
propagated from root cuttings [63], it might be capable of regeneration
from the roots under some circumstances. Bearberry may be a
seedbanking species with fire resistant seed [81,114].
POSTFIRE REGENERATION STRATEGY :
Prostrate woody plant, stem growing on organic mantle
Small shrub, adventitious-bud root crown
Ground residual colonizer (on-site, initial community)
Initial-offsite colonizer (off-site, initial community)
Secondary colonizer - off-site seed
