FIRE EFFECTS

SPECIES: Vaccinium arboreum | Tree Sparkleberry
IMMEDIATE FIRE EFFECT ON PLANT : Tree sparkleberry can be girdled and killed by fire [36]. Following a prescribed burn near Nacogdoches, Texas, mortality of important understory species, including tree sparkleberry, ranged from 11 to 31 percent [40]. DISCUSSION AND QUALIFICATION OF FIRE EFFECT : NO-ENTRY PLANT RESPONSE TO FIRE : The fire response of tree sparkleberry has not been well documented. Average height was reduced by a winter fire near Nacogdoches, Texas, but the average number of stems per plant increased [40]. Response was as follows [40]: winter burn - March 1974 control 1973 1975 1973 1975 avg. ht. (cm) 243 214 288 317 avg. # stems/ plant 1.15 1.69 1.07 1.00 Many ericaceous shrubs sprout from the root crown or rhizomes after aboveground vegetation is destroyed by fire. The postfire increase in stems per plant suggests that sprouting may sometimes occur. However, sprouting in tree sparkleberry has not been discussed in the available literature. Reestablishment presumably occurs through seedling establishment where plants are killed by fire. Many birds and mammals transport seed from adjacent unburned areas. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : NO-ENTRY FIRE MANAGEMENT CONSIDERATIONS : Wildlife management: Prescribed fire can be an effective means of managing tree sparkleberry thickets for wildlife habitat in some areas [42]. Prescribed fire can promote livestock forage and deer browse [21] and may have some potential for increasing fruit production [40]. Deer utilization of tree sparkleberry before and after a prescribed fire in Texas was as follows [21]: unburned burned 1958 1959 1960 1958 1959 1960 (before fire) (after fire) (percent utilization) 6 17 11 4 57 18 However, researchers caution that excessive burning for wildlife can result in loss of overstory and midstory hardwoods [21]. Prescribed fire: Managers frequently spray herbicides on southern pine forests and allow 2 years for the release of native bunchgrasses [36]. Bunchgrass development provides a uniform fuel for subsequent prescribed fires. Backfires can then be used to kill "low quality" hardwoods such as tree sparkleberry [36]. However, researchers note that blackjack oak-hickory-tree sparkleberry associations commonly occur on poor sites [36]. Limited growth potential on these sites may make prescribed burning for hardwood control uneconomical [36]. Nutrient content: Nutrient content of tree sparkleberry browse may be altered by burning.
