SPECIES: Gaylussacia dumosa
GENERAL DISTRIBUTION : Dwarf huckleberry is distributed along the coastal regions of Newfoundland and Nova Scotia south to central Florida and east to western Mississippi and central Tennessee. Disjunct populations occur in the mountains of West Virginia, southwestern North Carolina, and western South Carolina [5,7,11,16].

SPECIES: Gaylussacia dumosa
IMPORTANCE TO LIVESTOCK AND WILDLIFE : Mammals such as raccoon, gray fox, red fox, skunk, chipmunk, and squirrel feed on the fruit of dwarf huckleberry [23,24]. Dwarf huckleberry is also eaten by roughed grouse, wild turkey, and quail [15].

SPECIES: Gaylussacia dumosa
GENERAL BOTANICAL CHARACTERISTICS : Dwarf huckleberry is a small, deciduous, erect, much-branched, rhizomatous shrub which grows from 12 to 30 inches (30-75 cm) in height [7,11]. Many stems ascend from the base, forming a low, dense, rounded crown. The twigs are usually copiously pubescent with short, curly hairs. The small deciduous leaves are simple, leathery, obovate to elliptical with the lower surface typically glandular. The bell-shaped tubular flowers are borne on racemes at the end of the branchlets. The fruit is a berry with 10 nutlets, each carrying one seed [11,23,24]. RAUNKIAER LIFE FORM : Phanerophyte (nanophanerophyte) Chamaephyte REGENERATION PROCESSES : Dwarf huckleberry can reproduce through seed, although details have not been described [12,14]. Seeds are dispersed by a variety of birds and mammals [23,24]. Dwarf huckleberry sprouts from underground rhizomes or runners after aboveground vegetation is removed by fire or other types of disturbance [1,2,12]. SITE CHARACTERISTICS : Dwarf huckleberry commonly grows in pine forest or pine barrens, and at the edge of shrub-tree bogs, pitcher plant bogs, and bays [7,8,11]. Dwarf huckleberry grows on xeric to mesic sites with well-drained sandy to clayey soils [11,15]. Common overstory associates of dwarf huckleberry include eastern red cedar (Juniperus virginiana), tamarack (Larix laracina), redbay (Persea borbonia), sweetbay (Magnolia virginia), and flowering dogwood (Cornus florida). Common understory associates include dangleberry (Gaylussacia frondosa), yaupon (Ilex vomitoria), fetterbush (Leucothoe racemosa), and blueberry (Vaccinium spp.) [3,6,15,21]. SUCCESSIONAL STATUS : Fire is an integral part of pine barrens, pine flatwoods, and sand pine scrub communities in which dwarf huckleberry grows [2]. These communities have been described as "pyric disclimax" or fire climax communities. Fire in these communities does not initiate multistage succession but instead rejuvenates species which were present in the preburn community, such as dwarf huckleberry [4,13,19]. SEASONAL DEVELOPMENT : Dwarf huckleberry flowers in early spring; the fruit ripens in late summer or early fall [11].


SPECIES: Gaylussacia dumosa
FIRE ECOLOGY OR ADAPTATIONS : Dwarf huckleberry is well able to persist despite periodic fire [12,14]. Abrahamson [2] reports that dwarf huckleberry "exhibits a 'sit and wait' strategy, in that plants apparently survive with little aboveground biomass for long periods of time before fire causes release from shading and/or nutrient depletion." Dwarf huckleberry typically sprouts from underground rhizomes after the foliage is consumed by fire [2]. Birds and mammals may transport some seed to burned sites. POSTFIRE REGENERATION STRATEGY : survivor species; on-site surviving rhizomes off-site colonizer; seed carried by animals or water; postfire yr 1&2


SPECIES: Gaylussacia dumosa
IMMEDIATE FIRE EFFECT ON PLANT : Fire typically kills aboveground portions of dwarf huckleberry [1,19]. Underground rhizomes are generally protected from the damaging effects of heat and apparently survive most fires. DISCUSSION AND QUALIFICATION OF FIRE EFFECT : NO-ENTRY PLANT RESPONSE TO FIRE : Fire stimulates the growth of dwarf huckleberry [1,2]. Density and cover of dwarf huckleberry reached peak levels 1 year after a January prescribed burn in central Florida [2] Plants will typically sprout from underground rhizomes after aboveground vegetation is consumed [19]. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : NO-ENTRY FIRE MANAGEMENT CONSIDERATIONS : Fruit production of dwarf huckleberry was higher on burned sites than on unburned sites [1,2]. Fire exclusion greatly reduced density and cover of dwarf huckleberry on slash pine (Pinus elliottii) plantations in Georgia [14].
