Colonial National Historical Park<br />

CLASSIFICATION INFORMATION<br />

Status: St<strong>and</strong>ard.<br />

Confidence: 1 - Strong.<br />

Comments: <strong>Classification</strong> of this type is supported by two regional analyses of Maryl<strong>and</strong> <strong>and</strong><br />

Virginia plot data conducted by VDNH for the NCR vegetation mapping project. It is<br />

represented by 15 plots from the greater NCR region <strong>and</strong> an additional 57 plots from The<br />

Peninsula in York County, Virginia (Grafton Ponds complex). Delaware examples contain<br />

Quercus spp. (oaks) <strong>and</strong> Magnolia virginiana (sweetbay). In Maryl<strong>and</strong>, Clethra<br />

(sweetpepperbush) is more prominent than Leucothoe (doghobble), Quercus phellos (willow<br />

oak) less characteristic than Nyssa sylvatica (blackgum).<br />

Similar Associations:<br />

• Pinus serotina / Magnolia virginiana / Vaccinium corymbosum / Carex atlantica Woodl<strong>and</strong> (CEGL006470).<br />

• Populus heterophylla - Acer rubrum - Quercus palustris - Liquidambar styraciflua Forest (CEGL006469).<br />

• Quercus (phellos, pagoda, michauxii) / Ilex opaca var. opaca / Clethra alnifolia / Woodwardia areolata Forest<br />

(CEGL004644).<br />

• Quercus palustris - (Quercus bicolor) - Acer rubrum / Vaccinium corymbosum / Osmunda cinnamomea Forest<br />

(CEGL006240).<br />

• Quercus phellos / Carex (albolutescens, intumescens, joorii) / Climacium americanum Forest (CEGL007403)--of<br />

the Virginia Piedmont <strong>and</strong> more southerly areas, dominated by Quercus phellos.<br />
