Comm #2636	Taxodium distichum - Taxodium ascendens / Panicum hemitomon Swamp Woodland » more details accession code: urn:lsid:vegbank.org:commConcept:33254-{7AF7CC8D-7C25-4A63-BA7F-9561CEFB8985}	NatureServe Biotics 2019	4	This association represents narrow wooded shorelines of natural Mid-Atlantic Coastal Plain acidic/blackwater lakes (peatlands lakes and Carolina bays). This type is found on nearly all natural lakes in the Coastal Plain of North Carolina with the exception of Lake Waccamaw. Vegetation is quite sparse and low in species diversity; the vegetated zone is typically only a few meters in width. Overstory is typified by an open canopy of <i>Taxodium distichum</i> and occasionally <i>Taxodium ascendens</i>. Individual cypress trees tend to be small/stunted, and are likely quite old. Cypress regeneration is noticeably absent in most examples. A sparse shrub layer, consisting of <i>Vaccinium</i> sp. (probably <i>Vaccinium formosum</i>), <i>Cyrilla racemiflora</i>, and <i>Eubotrys racemosa</i>, is often present. These shrubs appear to be distributed in clumps as they are rooted on either hummocks or cypress knees and bases. Beds of <i>Panicum hemitomon</i> may also be present and patchily distributed.

The shrub layer can be sparse to dense and is characterized by <i>Quercus pumila</i> and <i>Vaccinium myrsinites</i>, but <i>Diospyros virginiana, Gaylussacia dumosa</i>, and others are also common. The species-rich herbaceous stratum is characterized by <i>Aristida beyrichiana</i> and <i>Sporobolus junceus</i>, which both often obtain high abundance.
Comm #2638	Picea glauca - Thuja occidentalis - Juniperus communis / Iris lacustris - Carex eburnea Shrubland » more details accession code: urn:lsid:vegbank.org:commConcept:33974-{B898F120-832A-44BC-A16E-8FCF6CF7B2E2}	NatureServe Biotics 2019	4	The scrub conifer / dwarf lake iris alvar shrubland type is found in the central Great Lakes region of the United States and Canada, in northern Michigan, and in Ontario on the southern shores of Manitoulin Island and the Bruce Peninsula. Stands occur on very shallow organic soils (usually 20-30 cm deep) over flat limestone or dolostone outcrops (pavements). This community has a characteristic soil moisture regime of seasonal flooding or saturation in early spring and late fall, combined with summer dry periods in most years (except unusually wet years). This community often occurs as openings within a forested landscape; it is not always associated with other alvar communities. When it occurs in a landscape mosaic with other alvar communities, it typically occurs as small patches adjacent to little bluestem alvar grassland, creeping juniper - shrubby cinquefoil alvar pavement, and tufted hairgrass wet alvar grassland. Scrub conifer / dwarf lake iris alvar shrubland has over 25% cover of tall and short shrubs. The tall shrubs (2-5 m tall) in this shrubland are scrub forms of tree species such as <i>Picea glauca, Thuja occidentalis, Larix laricina</i>, and <i>Abies balsamea</i>. There is less than 10% cover of trees over 5 m tall. The typical short shrubs (0.5-2 m tall) are <i>Juniperus communis, Prunus virginiana, Diervilla lonicera, Shepherdia canadensis, Cornus sericea</i>, and <i>Rhamnus alnifolia</i>. Underneath and between the shrubs is a 'lawn' dominated by <i>Iris lacustris</i> and <i>Carex eburnea</i>. Other characteristic species are <i>Arctostaphylos uva-ursi, Carex richardsonii</i>, and <i>Danthonia spicata</i>. The herbaceous layer has an average of 82% cover. Less than 10% of the ground surface is exposed bedrock, including bedrock covered with lichens and mosses.
Comm #2639	Spartina bakeri - Muhlenbergia filipes - Andropogon glomeratus - Rhynchospora colorata Marsh » more details accession code: urn:lsid:vegbank.org:commConcept:33297-{151CF79C-6AB6-4D5F-9638-FC079C5E6B42}	NatureServe Biotics 2019	4	These seasonally flooded coastal interdunal swales and related depressions occur in Florida and possibly southeastern Georgia, and are dominated by <i>Spartina bakeri</i>, or at least with substantial cover of it. <i>Muhlenbergia filipes</i> may be codominant; <i>Andropogon glomeratus</i> and <i>Aristida</i> sp. are occasionally present.
