Plant Response to Fire
Low sweet blueberry generally sprouts from rhizomes and the root crown
after aboveground vegetation is consumed by fire [65,83]. Plants may
also sprout from buds located on the stem base [83,157], but stems that
arise from underground rhizomes are generally more vigorous than those
that develop from partially burned aboveground stems . Rhizome
sprouting is much slower than crown sprouting . Some
reestablishment via seed germination may occur under favorable
Fire intensity and severity, season of burn, community type, and soil
are important factors influencing postfire response [138,148,161].
Cover and stem density commonly increase rapidly , and recovery may
be well underway within 4 to 5 postfire months [55,57]. Low sweet
blueberry was well represented within 4 months after an intense fire
destroyed all aboveground vegetation in a spruce stand in Manitoba .
In many areas, including parts of Nova Scotia and Ontario, low sweet
blueberry regains prominence 2 to 3 years after fire [6,106,144].
Although initially reduced after fire in jack pine and black spruce
communities, low sweet blueberry increased beyond prefire levels after 5
years [10,42,109]. Recovery may be delayed after hot fires. Low sweet
blueberry was present within 13 years after a severe wildfire in a red
pine-white pine forest . Hall and others  reported that V. a.
forma nigrum tends to increase more rapidly than does V. a. forma
angustifolium in fields that are burned regularly.
Fruit is not produced the year of the burn but is produced in abundance
during the next 3 postfire years [25,28,161]. In general, young
healthy plants regenerate more successfully than older, decadent ones
. Where clones are extremely decadent, it may take three seasons of
postfire growth before fruit production and vigor reach "satisfactory
levels" . Some researchers report that burning too frequently can
cause fruit yields to decline .
Increases in low sweet blueberry after fire may be due in part to the
stimulatory effect of nutrients added by ash deposition or changes in pH
. Blackened ground absorbs heat and may promote earlier fruit
