Quercus rubra / Polypodium virginianum Woodland (CEGL006320 ECS) — G3G5LNP SUGGESTED NAME: Quercus rubra – Betula alleghaniensis / Polypodium virginianumWoodlandRed Oak / Eastern Rockcap Fern Woodland[Red Oak Talus Slope Woodland]Description: Open, bouldery, acidic talus slope woodlands in the Northern Appalachian and Lower New England /Northern Piedmont ecoregions. Habitat (large talus and boulders) rather than geography differentiates this associationfrom Quercus rubra / Vaccinium spp. / Deschampsia flexuosa Woodland (CEGL006134). Ericads generally lacking, vinesand ferns more characteristic. Common associates are species of Corydalis, Woodsia, Dryopteris as well asParthenocissus quinquefolia, Polypodium virginianum, Tsuga canadensis, Pinus strobus. 6/98 NAP Very open tomoderately closed canopy, heterogeneous composition of Quercus rubra, Acer saccharum, Betula nigra, Betulaalleghaniensis, Betula papyrifera, Betula populifolia, Fagus grandifolia, Acer rubrum. Scattered and clumped tallshrubs/small trees include Acer spicatum, Acer pensylvanicum, Rubus spp., Viburnum acerifolium (occasional), Ribesspp. Prevalent component of vines are Parthenocissus quinquefolia, Parthenocissus vitacea, Toxicodendron radicans,Celastrus scandens, Polygonum cilinode. Scattered ferns and herbs are Dryopteris marginalis, Polypodium virginianum,Pteridium aquilinum, Carex pensylvanica, Corydalis sempervirens (localized), Solidago bicolor, Solidago caesia, andothers. Acidic talus slopes of low-elevation valleys. Substrate is bouldery talus derived form acidic bedrock. Elevationrange is roughly 500-2000 feet. Groundcover is exposed talus, moss-covered boulders and deciduous litter.LNP Scale: Small to large patch Distribution: LimitedTNC Ecoregions: 61:C, 62:C, 63:CReferences:State SRank State NameCT S?MA S4 Acidic Talus Forest / Woodland+ME S3 Acidic Talus+NH S?

Open, stunted to somewhat closed canopy of Quercus rubra. Quercusprinus may be codominant. Common associates are Quercus alba, Betula lenta and Acer rubrum with minor componentof Quercus velutina, Betula populifolia, Betula papyrifera and Pinus rigida. Tall-shrub layer is often lacking but may includeAcer spicatum, Sambucus racemosa, Rhus typhina, Kalmia latifolia, Hamamelis virginiana, Viburnum nudum var.cassinoides, Rhododendron spp. Ericaceous shrubs and graminoids are characteristic. Well-developed low-shrub cover ofVaccinium angustifolium, Vaccinium pallidum, Gaylussacia baccata, Kalmia angustifolia. Scattered grasses includeDeschampsia flexuosa, Danthonia spicata, Carex pensylvanica, and herbs include Gaultheria procumbens, Aralianudicaulis. Herbs: Pteridium aquilinum, Aralia nudicaulis, Maianthemum canadense, Aster acuminatus, Corydalissempervirens, Deschampsia flexuosa, Carex pensylvanica, Polypodium virginianum. Environmental setting: Talus slopes,rocky slopes and summits of low, moderate or high elevations. Soils are shallow, well-drained, nutrient-poor acidic gravelsand coarse sands.

Results for Terrestrial Communities and Systems *Modification to Standard MethodThe selection and exact spatial arrangement of the target element occurrences was left tothe understanding and judgment of the state Heritage Programs, TNC Field Offices, andother partners with guidance offered by the community working group. However, it isnoteworthy that this has also allowed states to select for the portfolio occurrences that donot appear to meet established size, condition, or landscape context criteria. Theconsequence has been that the portfolio contains an excess number of occurrences forsome community types, some of which do not meet their minimum viability criteria.Occurrences with questionable viability were also selected for community associationsthat did not meet their goals, with the understanding that 1) the database records be editedto reflect the new and improved viability information, and 2) certain portfolio sites mayneed to be removed in the future if the portfolio goal can be met with better, more viable,occurrences. In short, there is a mixed degree of confidence that all the community sitesselected should or will remain in the portfolio. An improved process is required tomaintain suitably conservative viability standards and a scientifically rigorous portfoliowhile still allowing states the opportunity to select which occurrences should become apart of the portfolio.Community classificationIn developing the Lower New England – Northern Piedmont Classification (Lundgren etal, 2000) an initial list of approximately 200 vegetation associations was selected aspotentially occurring in the ecoregion based on known or suspected ranges of eachassociation. Following review, a number of types were determined not to occur in theecoregion or were not deemed as recognizable or distinct associations. One addition wasdescribed and several new types were proposed for further study. The result was a total of153 NVC (National Vegetation Classification) associations currently described withinthis ecoregion with an additional 7 more to be defined with additional classification andinventory in the future. A total of 107 NVC Alliances (broader than association level)were represented: 40% Forests (>60% cover of trees), 14% Woodlands (30-60% treecover), 12% Shrublands, and 34% Herbaceous types.The revised National Vegetation Classification associations were not available for theanalysis of documented community occurrences in LNE-NP during this stage of theassessment process. Therefore, to coordinate community occurrences across state lines,conduct an assessment of occurrence viability, and set goals, all community occurrencesin the database were assigned to one of seventeen ecological groups which are listed inTable 4.* Anderson, M.G. and S.L.
