FIRE ECOLOGY
SPECIES: Arctostaphylos viscida | Whiteleaf Manzanita 



FIRE ECOLOGY OR ADAPTATIONS : 
Plant adaptations:  Whiteleaf manzanita establishes after fire by
fire-stimulated germination of dormant seeds stored in the soil
[13,22,23].

Fire ecology:  Whiteleaf manzanita has various morphological adaptations
which encourage fire.  During drought, the plant undergoes branch
die-back, which contributes to fuel loading.  Continuous shedding of
bark adds additional fuel [36].  The surface-to-volume ratio of leaves
and twigs are perfectly scaped for maximum air circulation, resulting in
more complete burning of the plant and adding to fire intensity [20].
Additionally, leaves and twigs contain flammable oils and terpenes [40].
Philpot [40] has reported the heat value of whiteleaf manzanita leaves
and twigs at 8,942 Btu per pound (4,973 cal/kg).


POSTFIRE REGENERATION STRATEGY :
