FIRE ECOLOGY
SPECIES: Holodiscus discolor
| Oceanspray
Oceanspray is only moderately resistant to fire [103,114], but is well adapted to disturbance by fire [82]. Although readily top-killed, this species is generally quite resistant to fire mortality [13,18,99,103,116]. Oceanspray survives fire by regenerating from soil-stored seed or sprouting from surviving root crowns [13,103,114,111,82]. The most common postfire regeneration stategy of oceanspray is vegetative regeneration. Generalized information indicates that postburn seedling establishment is rare [114,82], but seedling cover may be greater on high severity burns [77,78].
Fire regimes for plant communites in which oceanspray occurs are summarized below. For further information regarding fire regimes and fire ecology of communities where oceanspray is found, see the "Fire Ecology and Adaptations" section of the FEIS species summary for the plant community or ecosystem dominants.
