FIRE ECOLOGY

SPECIES: Rubus ursinus | Trailing Blackberry
FIRE ECOLOGY OR ADAPTATIONS : Trailing blackberry is a common invader on recently burned sites in the Pacific Northwest [16,39,53]. Populations are capable of dramatic and rapid expansion on disturbed sites [25,66] through sprouting or seedling establishment [9,16]. Belowground regenerative structures are generally well protected from the harmful effects of heat and permit rapid recovery where trailing blackberry plants were present in the preburn community. Seedbanking is also an important postfire regenerative strategy [52]. Seeds accumulate in the soil or duff, remaining viable long after this seral species has been eliminated from mature forest communities. Seeds commonly germinate in great abundance after fire. The relatively large, sweet, succulent fruit of blackberries amply "reward" animal dispersers [40], and some postfire dispersal of seed from off-site is probable. 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)
