SPECIES: Gaylussacia frondosa | Dangleberry
ABBREVIATION : GAYFRO SYNONYMS : Gaylussacia tomentosa (Gray) Small Gaylussacia nana (Gray) Small [36] SCS PLANT CODE : GAFR2 COMMON NAMES : dangleberry hairy dangleberry TAXONOMY : The currently accepted scientific name for dangleberry is Gaylussacia frondosa (L.) T. & G. (Ericaceae) [13,26]. The following three varieties are recognized: G. f. var. frondosa G. f. var. tomentosa Gray [5,6,14,15] G. f. var. nana Gray [5,14,15] Wunderlin [36] considers the two nontypic varieties to be separate species. Gaylussacia f. var. tomentosa is distinguished by densely short-pubescent twigs and lower leaf surfaces. Gaylussacia f. var. nana is distinguished by its shorter stature, shorter branches, and columnar aspect, as well as short-pubescent stems [15].

SPECIES: Gaylussacia frondosa | Dangleberry
GENERAL DISTRIBUTION : Dangleberry occurs in the eastern United States. The range of the typical variety extends from New York, Massachusetts, and New Hampshire south along the Atlantic Coastal Plain to South Carolina [15]. Although dangleberry occurs primarily east of the Appalachian Mountains, it has been reported in Ohio, Tennessee, and West Virginia [3,13]. Gaylussacia frondosa var. tomentosa occurs from South Carolina to central Florida and west to Alabama [14,26]. The range of G. f. var. nana extends from southern Georgia south to central Florida, and west to Mississippi and possibly Louisiana [15].

It occurs in dry and moist woods, particularly in pine (Pinus spp.) flatwoods [7]. Dangleberry frequently occurs with other ericaceous shrubs including highbush cranberry (Vaccinium corymbosum), hillside blueberry (V. pallidum), Lyonia spp., sheep-laurel (Kalmia angustifolia), wintergreen (Gaultheria procumbens), dwarf huckleberry (Gaylussacia dumosa), and black huckleberry (G. baccata) [9,17,28,31]. At swamp and drainage margins, dangleberry is associated with red maple (Acer rubrum), southern bayberry (Myrica cerifera), sweetbay (Magnolia virginiana), sweet pepperbush (Clethra alnifolia), redbay (Persea borbonia), loblolly bay (Gordonia lasianthus), fetterbush (Leucothoe racemosa), and Sphagnum spp. [8,9,18,34]. In longleaf pine (Pinus palustris) and slash pine (P. elliottii) communities, dangleberry occurs with bitter gallberry (Ilex glabra), wiregrass (Aristida stricta), and saw-palmetto (Serenoa repens) [18,28,31]. Dangleberry is listed as a dominant species in the following publications: 1. The phytosociology of the Green Swamp, North Carolina [18] 2. The ecology of southeastern shrub bogs (pocosins) and Carolina bays: a community profile [28]


SPECIES: Gaylussacia frondosa | Dangleberry
WOOD PRODUCTS VALUE : NO-ENTRY IMPORTANCE TO LIVESTOCK AND WILDLIFE : Dangleberry provides food, shelter, and cover for wildlife. Numerous birds including sharp-tailed grouse, greater prairie chicken, bobwhite quail, wild turkey, mourning dove, catbird, and scarlet tanager eat the berries. Black bear, gray fox, raccoon, and fox squirrel also eat the berries. White-tailed deer and cottontail rabbit browse stems lightly [16,33]. PALATABILITY : NO-ENTRY NUTRITIONAL VALUE : NO-ENTRY COVER VALUE : NO-ENTRY VALUE FOR REHABILITATION OF DISTURBED SITES : In Lehigh Gap, Pennsylvania, where soil is contaminated with heavy metals from a nearby smelter, dangleberry cover and density are lower than in uncontaminated areas [17]. OTHER USES AND VALUES : Dangleberry fruits are edible [33]. MANAGEMENT CONSIDERATIONS : Ehrenfeld [7] determined shrub biomass and nitrogen concentrations of dangleberry foliage from the New Jersey pine barrens. Dangleberry produces small stems but abundant leaves, so it has low shrub biomass but high net biomass production [7,8]. Regression equations for predicting dangleberry biomass which relate stem diameter to dry weight are available [8].

GENERAL BOTANICAL CHARACTERISTICS : Dangleberry is a native, deciduous, freely branched slender shrub [26,33]. The typical variety grows to 6 feet (2 m) in height, G. f. var. tomentosa grows to 3 feet (1 m) in height, and G. f. var. nana grows to 2 feet (0.6 m) in height [14]. The fruit is a fleshy drupe containing around 10 seeds [13,33]. Aerial stems arise from extensively branched rhizomes to form clones [22]. The aerial stems are usually 3 to 72 inches (7.6-183 cm) apart on the rhizomes. The woody rhizomes are usually 0.13 to 0.38 inches (0.3-1.0 cm) in diameter. They are generally confined to the humus layer and the top 2 inches (5 cm) of the A1 soil horizon. Roots are generally confined to the same soil level as the rhizomes [20]. RAUNKIAER LIFE FORM : Geophyte REGENERATION PROCESSES : Dangleberry regenerates by vegetative reproduction and seed. Existing dangleberry colonies regenerate after disturbance primarily by sprouting from rhizomes. Destruction of aboveground stems stimulates sprouting [21,22]. Dangleberry probably colonizes new sites by animal-dispersed seed [12]. Dangleberry was present in the understory of an oak (Quercus spp.)-pine woods in the New Jersey pine barrens but absent from the seedbank [23]. SITE CHARACTERISTICS : Dangleberry occurs primarily on the southeastern United States coastal plains and is infrequent on the Piedmont. It grows in sandy and rocky woods and on the margins of shrub bogs and swamps [5,14,26]. Dangleberry grows on acidic, low-nutrient, poorly to well-drained soils [1,12,18,28]. It grows on both organic and mineral soils but prefers an intermediate soil type with a shallow organic layer [18]. At the outermost fringe of a bog in North Carolina, a tall shrub community which included dangleberry occurred on soil with a 10- to 12-inch (25-30 cm) organic layer [34]. Dangleberry is a facultative phreatophyte; its roots extend to the water table in lowland areas, but do not reach the water table in upland areas [20]. SUCCESSIONAL STATUS : Facultative Seral Species Dangleberry is probably intermediate in shade tolerance but may be more productive when grown in sunlight. It is an important component in older stands of the New Jersey pine barrens [29]. In Massachusetts, dangleberry occurs in a mid- to late-successional forest dominated by white oak (Quercus alba), American beech (Fagus grandifolia), and sassafras (Sassafras albidum) [24]. SEASONAL DEVELOPMENT : Dangleberry flowers March through May, and fruits mature July through August [26,35].

FIRE ECOLOGY OR ADAPTATIONS : Dangleberry is fire tolerant. Aboveground parts are destroyed by most fires, but dormant buds on rhizomes usually survive and sprout [4,21]. Dangleberry occurs in habitats that regularly experience fire, including oak scrub, oak-pine scrub, and longleaf pine-slash pine communities [4,31]. Low-severity fire encourages prolific vegetative growth of dangleberry [22]. However, severe fire that burns the humus layer, where many of the rhizomes are, can probably reduce or eliminate dangleberry from a site [20]. Frequent fire may decrease dangleberry cover [4], probably because of inadequate time between fires to replenish root resources. Dangleberry regeneration after fire is probably independent of aboveground, but not belowground, severity. Areas that burn frequently may have low levels of humus, so rhizomes must grow in the mineral soil and are less vulnerable to fire. For instance, dangleberry persists in the New Jersey pine barrens which historically burned by severe crown fire every 20 to 25 years [2,20]. In the Cumberland Island National Seashore, Georgia, an oak-pine scrub community with an understory of dangleberry, saw-palmetto, and Lyonia spp. has natural 20- to 30-year fire intervals. This community may support fire as often as every 5 years [31]. POSTFIRE REGENERATION STRATEGY : Rhizomatous shrub, rhizome in soil

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].
