FIRE ECOLOGY

SPECIES: Rubus idaeus | Red Raspberry
FIRE ECOLOGY OR ADAPTATIONS : The life cycle of red raspberry is integrally associated with disturbances such as fire. In many areas of vigorous fire suppression, both plant vigor and abundance have decreased [66]. Red raspberry typically flourishes, completes its life cycle and declines within the early years after disturbance [73]. As shade levels increase in the postfire community and soil nitrate levels drop (generally during the first 5 years after fire), red raspberry shifts resource allocation from vegetative growth to seed production [39,99]. Although the plants themselves soon senesce and die, viable seed persists for decades [62,73], germinating in great numbers after the next fire [100] creates favorable conditions for growth and establishment. Seed is effectively scarified by heat [78,94], and exposed mineral soil serves as a favorable substrate for early growth and development [26]. Underground regenerative structures appear to be well protected from the damaging effects of heat [28,52], and reestablishment is typically rapid where plants were present in the preburn community. POSTFIRE REGENERATION STRATEGY : Tall shrub, adventitious-bud root crown Rhizomatous shrub, rhizome in soil Geophyte, growing points deep in soil Ground residual colonizer (on-site, initial community) Initial-offsite colonizer (off-site, initial community)
