Description

A description of Gaylussacia dumosa is provided in The Flora of North America. Size class of this plant is between 1 and 3 feet.[1]

Distribution

Its main distribution is throughout the southeastern coastal plain, from New Jersey to Florida and west to eastern Louisiana, and less common more inland.[2] It is also native to the Canadian provinces of Quebec, New Brunswick, Nova Scotia, and Newfoundland & Labrador; it is also found in St. Pierre Miquelon located near Newfoundland & Labrador province.[3]

Ecology

Habitat

Gaylussacia dumosa is commonly found in mesic to xeric, acidic woodlands and forests.[2] This species has also been observed in a variety of habitats including pine and saw palmetto flats and other flatwoods, pine plantations, low pine savannas, scrub, sand ridges, bluffs, edge of a pitcher plant bog, and sandhills. Soils include drying and moist sand, acid sandy peat, sandy loam, and sandy to mucky soils.[4] It is restricted to native groundcover with a statistical affinity in upland pinelands of South Georgia. [5] G. dumosa responds negatively to soil disturbance in longleaf pine communities in South Carolina.[6] However, it has been observed in some slightly disturbed areas including along the edge of open powerline corridors, a disturbed wiregrass area cleared by rootrake, and sandy roadsides.[4] In other areas, it can also be found in low pinelands as well as bogs and pond margins.[1]

Associated species include Andropogon sp., Aristida stricta, Aristida sp., Sorghastrum sp., Pinus palustris, Pinus elliottii, Serenoa repens, Vaccinium darrowii, Vaccinium myrsinites, Vaccinium sp., Quercus laevis, Quercus minima, Quercus pumila, Diospyros virginiana, Actinospermum angustifolium, Leptoloma cognatum, Gaylussacia sp., Kalmia hirsuta, and others.[4]

Phenology

Generally, G. dumosa flowers from March to June and fruits from June until October.[2] It has been observed to flower March to May and in October with peak inflorescence in April, and fruit from April until July.[7][4]

Seed dispersal

This species is thought to be dispersed by consumption by vertebrates. [8] In particular, it has found to be dispersed by gopher tortoise (Gopherus polyphemus).[9]

Fire ecology

Gaylussacia dumosa commonly grows in pine savannas and other habitats that are frequently burned.[4] It increases in frequency in response to fire, but crown height and width over time since fire does not change much.[10] One study found the amount of cover to dramatically increase in response to fire, but as time increased since fire disturbance, the percent cover of G. dumosa to decrease.[11] It is easily ignitable due to average litter depth and bulk density which adds to the fine fuels from the plant that are able to ignite.[12]

Pollination

The following Hymenoptera families and species were observed visiting flowers of Gaylussacia dumosa at Archbold Biological Station: [13]

Apidae: Apis mellifera, Bombus impatiens

Halictidae: Augochlorella aurata, A. gratiosa

Megachilidae: Megachile brevis pseudobrevis, M. integrella

Use by animals

It consists of approximately 2-5% of the diet for large mammals, 5-10% of the diet for small mammals, and 5-10% of the diet for various terrestrial birds.[14][15]

Conservation and management

Gaylussacia dumosa is listed as threatened by the Connecticut Department of Environmental Protection, the New Hampshire Division of Forests and Lands, and the Tennessee Department of Environment and Conservation. It is listed as endangered by the New York Department of Environmental Conservation and the Pennsylvania Department of Conservation and Natural Resources, and is listed as a species of special concern by the Rhode Island Department of Environmental Management.[3]
