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
Most Himalayan blackberry seed stored on-site in the soil or duff is
probably unharmed by fire.
DISCUSSION AND QUALIFICATION OF FIRE EFFECT :
PLANT RESPONSE TO FIRE :
Vegetative response: The Himalayan blackberry is capable of rapid,
extensive spread through trailing aboveground stems which root at the
nodes . 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 . 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 :
FIRE MANAGEMENT CONSIDERATIONS :
Wildlife species which consume large amounts of blackberries are often
benefited by fire .
