FIRE EFFECTS

SPECIES: Gaylussacia frondosa | Dangleberry
IMMEDIATE FIRE EFFECT ON PLANT : Most fires kill aboveground portions of dangleberry [4,21]. Moderate-severity or severe fire that burns the humus layer may also kill many of the rhizomes, thereby killing the plant. DISCUSSION AND QUALIFICATION OF FIRE EFFECT : NO-ENTRY PLANT RESPONSE TO FIRE : Surviving rhizomes sprout from dormant buds following fire [4,21]. A single low-severity fire usually encourages prolific dangleberry growth. Vigorous thickets of dangleberry with high stem densities arise after low-severity fire [22]. Buell and Cantlon [4] investigated the effects of fire frequency on an upland oak forest in New Jersey with a well-developed shrub layer. Low-severity prescribed fires were conducted in winter at 1-, 2-, 3-, 4-, 5-, 10-, and 15-year intervals. Dangleberry showed long-term decline in percent cover at fire intervals of 5 years or less. Dangleberry had 14 percent cover on unburned control plots and 0.5 percent cover on plots burned annually for 10 years. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : NO-ENTRY FIRE MANAGEMENT CONSIDERATIONS : In the North Carolina Coastal Plain, the fuel load was 17.3 tons per acre for a tall shrub community averaging 8 feet (2.4 m) in height. Dangleberry contributed 10 percent of the total fuel load [34]. In frequently burned 16- to 30-year-old slash pine forests in southeastern Georgia, dangleberry attained peak production 3 years after prescribed burning. It produced no fruit the first postfire year, 32 grams of fruit per 100 square meters the second year, and 104.4 grams of fruit per 100 square meters the third year, accounting for 23 percent of the total fruit production in the forests during the third postfire growing season. Dangleberry fruit production decreased substantially the fourth postfire year. The authors conclude that prescribed fire at 3-year intervals optimizes dangleberry and other forest species fruit production, but longer intervals (more than 5 years) allow less fire-tolerant mast-producing species to mature as well [16]. Because Buell and Cantlon [4] showed that dangleberry declines at fire intervals of 5 years or less, a prescribed fire interval longer than 5 years is probably best for long-term dangleberry fruit production. In a longleaf pine forest in Florida, fire during the growing season synchronized the postfire flower production of understory species including dangleberry [25].
