SPECIES: Rubus discolor | Himalayan Blackberry
IMMEDIATE FIRE EFFECT ON PLANT : Although Himalayan blackberry plants may be top-killed, actual mortality appears to be uncommon because of the prolific sprouting ability of this shrub. Most Himalayan blackberry seed stored on-site in the soil or duff is probably unharmed by fire. DISCUSSION AND QUALIFICATION OF FIRE EFFECT : NO-ENTRY PLANT RESPONSE TO FIRE : Vegetative response: The Himalayan blackberry is capable of rapid, extensive spread through trailing aboveground stems which root at the nodes [32]. Plants are presumably able to regenerate vegetatively and resume growth when portions of the aboveground stems remain undamaged. Most blackberries readily regenerate vegetatively from underground structures such as roots, rhizomes, or rootstocks when aboveground foliage is removed [11]. Regeneration through various underground structures, which are well protected from the direct effects of fire by overlying soil, is probable even when the aboveground vegetation is totally consumed by fire. Seedling establishment: Exposed mineral soil can provide a favorable seedbed, and extensive postfire establishment of on-site seed is commonly observed in many blackberries. Birds and mammals may also transport some viable seed to the site. Rate of postfire recovery: The weedy Himalayan blackberry is described as a "serious pest" which is well represented on many types of disturbed sites [7,14]. Its role as a vigorous invader on waste ground suggests the potential for rapid postfire recovery in many areas. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : NO-ENTRY FIRE MANAGEMENT CONSIDERATIONS : Wildlife species which consume large amounts of blackberries are often benefited by fire [20].
