HABITAT DESCRIPTION:
The green treefrog inhabits bottomland swamps and sloughs, primarily in the Coastal Plain (Martof et al. 1980, Redmond and Scott 1996). They can be found in brackish water (Conant and Collins 1998), and occur on many barrier islands along the Atlantic coast (Gibbons and Coker 1978).

Often found in ponds with lily pads and in river systems with water hyacinths (Wright and Wright 1949). Shallow wet sites with an abundance of shrubs are used extensively as well (Wilson 1995, Conant and Collins 1998). At night, this species will roam away from water to forage in fields and at the lights of farmsteads (Martof et al. 1980, Conant and Collins 1998, Wright and Wright 1949). It is often found in campground bathrooms, on kitchen windows, or on the side of well lit buildings actively foraging for insects (Mitchell 1991).

NATURE SERVE GLOBAL HABITAT COMMENTS:

Swamps, marshes, and the edges of ponds, lakes, and streams, particularly where there is abundant floating and emergent vegetation. During daytime, rests among cattail blades or other leaves or shaded branches. Eggs and larvae develop in shallow, still water. Males call while perched on plants next to water (up to 15 ft above surface) or while sitting on floating plants. Larvae occur mainly in dense floating vegetation.

372 Interdune Herbaceous Wetlands Dune swales with permanently flooded to intermittently exposed hydrology. Species composition depends on salinity and can include cut grass, spike-rush, mosquito fern, and hornwort. Interdune Pond, Maritime Wet Grasslands
75 Tidal Swamp Forest Swamp tupelo dominated forest with or without black tupelo and/or cypress trees. Restricted to the tidal zones in the coastal plain. May have inclusions of coastal red cedar woodlands. Tidal cypress - gum swamp
126 Interdune Wooded Depression Swamp Includes swamps dominated by sweetbay and swampbay or dogwood dominated forests. Maritime Shrub Swamp, Maritime Swamp Forest
380 Coastal Plain Fresh Water Emergent Emergent vegetation in fresh water seepage bogs, ponds and riverbeds of the coastal plain. Includes alliances dominated by sedges, eelgrass, as well as cane found in unforested cane-brakes. Small Depression Pond, Sandhill Seep, Floodplain Pool, Unforested Floodplain Canebrake, Riverscour Prairies, Vernal Pools
173 Coastal Plain Riverbank Shrubs Shrub dominated riverbanks, commonly dominated by willows and/or alders. Sand and Mud Bar
50 Coastal Plain Mixed Bottomland Forests Includes forests dominated by a variety of hardwood species, including sweetgum, cottonwood, red maple. Coastal Plain Bottomland Hardwood (in part), Coastal Plain Levee Forest
49 Coastal Plain Oak Bottomland Forest Bottomland forests dominated by deciduous oak alliances. Oaks represented can include swamp chestnut, cherrybark, willow, and/or overcup oak. Inclusions of loblolly pine temporarily flooded forests occur in patches. Hydrology is temporarily to seasonally flooded. Coastal Plain Bottomland Hardwoods (in part) blackwater subtype, brownwater subtype
158 Coastal Plain Nonriverine Wet Flat Forests Loblolly pine - Atlantic white-cedar - red maple - swamp tupelo saturated forests as well as forests dominated by loblolly, sweetgum, and red maple in non-riverine flats. Non-riverine Wet Hardwood Forest
41 Peatland Atlantic White-Cedar Forest Dense stands of Atlantic white cedar with saturated hydrology. Can include swamp tupelo, red maple, and pond pines with a moderate shrub and herb layer. Peatland Atlantic White-Cedar Forest
15 Seepage and Streamhead Swamps Includes extensive peat flats in the coastal plain, dominated by swamp tupelo, maples, and Atlantic white cedar alliances. In the sandhills includes streamhead pond pine and bay forests alliances. Saturated hydrology. Bay Forest, Small Depression Pocosin, Streamhead Atlantic White Cedar Forest, Streamhead Pocosins
30 Cypress-Gum Floodplain Forests Swamps dominated by black or swamp tupelo with or without Taxodium. Seasonally to semi-permanently flooded hydrology. Cypress-Gum Swamps

385 Oak Bottomland Forest and Swamp Forest The swamp chestnut oak, cherrybark oak, shumard oak and sweetgum alliance is one representative. Other alliances are dominated by water, willow, and overcup oaks. Swamp forests can be dominated by sweetgum, red maple, and black gum being dominant. Loblolly can occur in combination with sweetgum and red maple, or with tulip poplar. Includes saturated and semi- to permanently flooded forests in the mountains. Piedmont/Mountain Bottomland Forest, Piedmont/Mountain Swamp Forest
63 Coastal Plain Mesic Hardwood Forests Beech dominated forests with white oak and northern red oak as possible co-dominants. Dry-mesic to mesic forests on slopes and small stream bottoms in the coastal plain. Mesic Mixed Hardwood Forest, Basic Mesic Forests

67 Wet Longleaf or Slash Pine Savanna Wet flatwoods and pine savannas, typically dominated by longleaf pines, but slash or pond pines may be the dominant pines. Wet Pine Flatwoods
238 Piedmont/Mountain Submerged Aquatic Vegetation Seasonally to permanently flooded areas with aquatic vegetation. Waterlily, pondweed, hydrilla smartweed are a few of the species that can occur. Piedmont/Mountain Semipermanent Impoundment (in part)
239 Piedmont/Mountain Emergent Vegetation Emergent vegetation of all wetland hydrologies. Sites would commonly support species such as tussock sedge, rushs, and cattail alliances. Rocky Bar and Shore (in part)
267 Riverbank Shrublands Riverside shrubs with temporarily flooded hydrologies. Found in the both the Mountains and Piedmont. Containing dominants such as smooth alder and a Carolina or black willows. Sand and Mud Bar
