目錄非河流平木和沼澤
這個生態群組中，大部分季節性飽和至季節性洪水的森林都佔據了近平坦、寬闊的海岸平原露台和排水不良的泥炭地，以及舊而非常寬闊的溪流露台，不再受陸地洪水影響。在海岸平原的沙丘地區的沼澤溪頭和腳坡凹陷也出現一小小部分，水文學除了地下水波動之外，水文學也受到滲漏輸入的影響。類似的社區在北卡羅來納州已經得到充分記錄，並且可能在切薩皮克灣地區的露台向北延伸到馬里蘭州和特拉華州。在弗吉尼亞州，這些社區在本地範圍從東岸的內陸部分到沿岸平原的大多數低浮雕部分。該團體包含兩種飽和社區類型和兩種具有季節性洪水文制度。
Non-riverine saturated forests are frequently referred to as wet flatwoods. Most remaining examples of this vegetation occur on the outer Coastal Plain from the Eastern Shore to the Embayed Region, but scattered stands are also present in the inner and northern parts of the region. Habitats are nearly flat, with seasonally perched water tables. Some sites experience periodic sheet flows of anastomosing seepage from adjacent slope-base springs. Shallow, braided channels and depressions which pond water intermittently are frequent habitat features. Soils are silt, sand, and clay loams, sometimes with a thin (< 30 cm [12 in]) mantle of coarse, fibric peat. Late-successional stands of non-riverine saturated forests contain mixtures of hydrophytic oaks (Quercus spp.). Dominants, varying regionally, include swamp chestnut oak (Quercus michauxii), cherrybark oak (Quercus pagoda), willow oak (Quercus phellos), laurel oak (Quercus laurifolia), water oak (Quercus nigra), pin oak (Quercus palustris), and white oak (Quercus alba). Cutting and other disturbances result in higher proportions of sweetgum (Liquidambar styraciflua), red maple (Acer rubrum), and other intolerant trees. Small trees and shrubs include American hornbeam (Carpinus caroliniana), switch cane (Arundinaria tecta), American holly (Ilex opaca var. opaca), sweet pepperbush (Clethra alnifolia), sweetbay magnolia(Magnolia virginiana var. virginiana), coastal dog-hobble (Leucothoe axillaris), and highbush blueberries (Vaccinium spp.). Herb layers tend to be depauperate, but usually contain netted chain fern (Lorinseria areolata) and a variety of sedges, (e.g., Carex abscondita, Carex debilis, Carex intumescens var. intumescens). Large, rhizomatous colonies of Virginia chain fern (Anchistea virginica) and/or the sedges Carex striata var. brevis, Carex bullata var. greenei, and Carex barrattii occasionally dominate. Late-successional non-riverine saturated forests have been greatly reduced in extent or modified by extensive agricultural clearing, logging, conversion to pine silvicultures, and hydrologic alterations such as ditching and draining. Both oak-dominated community types in this group (see below) are now globally rare. Associated rare species in southeastern Virginia include the globally rare Virginia least trillium (Trillium pusillum var. virginianum), the federally listed Dismal Swamp southeastern shrew (Sorex longirostris fisheri), and the state-listed canebrake rattlesnake (Crotalus horridus atricaudatus).
現在比較後續的非河流濕硬木更普遍存在較後續的非河流濕硬木森林，主要由小松（ Pinus taeda ）、紅楓（ Acer rubrum ）和甜甘油（ Liquidambar styraciflua ）組成的混合物主要為主。在詹姆斯河以南的南部，交叉甘蔗（Arundinaria tecta）通常在這些非河流松木森林的灌木層中佔據分散至非常密集的殖民地。在那裡，許多這種組成的森林似乎都是演替林分，隨著該地區的火災基本上消除，它們取代了曾經廣泛的「藤叢」（即用散落的池松切換藤蔓稀樹草原）。類似的事件似乎已取代了橡木主導的非河流飽和森林和大西洋白雪松森林，在嚴重切割或災難性火災後。雖然這個群組中的修改社區並不是保護優先事項，但它們為目前已消滅的大麻植物提供了生態恢復的機會。此外，大量州稀有鳥斯溫森鳥（Limnothlypis swainsonii）與非河流松樹木森林有關。交換甘蔗被認為是幾種州和全球稀有昆蟲的寄宿植物。
Seasonally flooded non-riverine swamp forests that are somewhat similar to alluvial bald cypress - tupelo forests occur on poorly drained peatlands of the Coastal Plain. These communities are most abundant on terraces of the Embayed Region of extreme southeastern Virginia and northeastern North Carolina, but also occur in large, peat-filled hollows between ancient dunes behind Cape Henry in Virginia Beach. Habitats are non-riverine wetland flats with deep or shallow organic soils and seasonal flooding to depths of approximately 30 cm (12 in) by elevated water tables. Hummock-and-hollow microtopography is typical. Dominant trees are bald cypress (Taxodium distichum), swamp tupelo (Nyssa biflora), and red maple (Acer rubrum). Red maple now greatly dominates most stands because of extensive past logging, catastrophic fires, and ditching. Red bay (Persea palustris) and sweet pepperbush (Clethra alnifolia) are abundant in the lower woody layers. Also abundant are high-climbing vines of greenbriers (Smilax rotundifolia and Smilax laurifolia), poison ivy (Toxicodendron radicans var. radicans), climbing hydrangea (Hydrangea barbara), supplejack (Berchemia scandens), cross-vine (Bignonia capreolata), Virginia-creeper (Parthenocissus quinquefolia), and muscadine grape (Muscadinia rotundifolia var. rotundifolia). Netted chain fern (Lorinseria areolata) and Virginia chain fern (Anchistea virginica) are among the few herbs that occur regularly. The Tupelo - Bald Cypress Type of non-riverine swamp forest is the characteristic vegetation in and near the Great Dismal Swamp in Virginia. Its dense, vine-rich aspect gave the Swamp much of its historical reputation as a dark, mysterious, or dreadful place. Although most stands are now much altered, The Nature Conservancy has protected an impressive old-growth occurrence at Gum Swamp (City of Chesapeake) that contains bald cypress up to 1.75 m (5 ft 9 in) in diameter.
在海岸平原內部的沙丘中，這個群組的少數代表人，植被有點想起沼澤地大西洋白雪松森林和池塘松樹林和波科辛。大西洋白雪松（ Chamaecyparis thyoides ）、洛布洛利松（ Pinus taeda）、池塘松（Pinus serotina ）、紅楓（ Acer rubrum）、沼澤蘭（Nyssa biflora）和甜灣玉蘭（Magnolia virginiana var. 維吉尼亞納 （ Lyonia lucida）（Lyonia lucida ），沼澤西蘭（Cyr illa racemiflora ），甜胡椒樹（ Clethra alnifolia），卡羅萊納月桂（卡爾米亞卡羅萊納），灰塵的青葉（Zenobia pululenta），墨莓（Ilex glabra ），光滑的冬季（卡爾米亞卡羅琳娜）上構成一個開放的樹枝組 合上。 青葉草）、常綠的海 莓（ Morella Caroliniensis）、綠草（Smilax spp.） ，以及幾個落葉棲息地。肉桂楊桃（ Osmundastrum cinnamomeum ），弗吉尼亞州鏈 dương 植物（ Anchistea virginica）和網鏈藤（Lorinser ia areolata）可能佔據草本層。由於這些混合的常綠沼澤通常濕潤，因此在乾燥期間在鄰近高地的火災擴散到它們時，可能會遇到罕見但嚴重的燒傷。
非河流沼澤森林與白柏-圖佩洛沼澤不同，因為它們出現在非流水、較淺水的有機土壤上（vs.深入水浸泡的水泥和底部），以及低層花卉植物。這群組的社群在全球範圍內非常罕見到稀有，並為聯邦列入名錄的荒涼沼澤東南鼠鼠（Sore x longirostris fisherii）和兩隻稀有蝙蝠提供棲息地。
