CEGL006024 Juniperus virginiana Ruderal Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Eastern Red-cedar Ruderal Forest
Colloquial Name: Northeastern Ruderal Red-cedar Forest
Hierarchy Level: Association
Type Concept: This association is a broadly defined old-field early-successional community occurring in a variety of environmental settings in the northeastern states. Canopy closure and height are variable, as are shrub and herbaceous associates. Juniperus virginiana dominates the canopy layer. Common associates, typically occurring as scattered individuals, may include Pinus strobus, Acer rubrum, Liriodendron tulipifera, Quercus spp., and Prunus serotina. Shrub cover varies, with the most forested stands having little or no shrub cover. Exotic shrubs such as Elaeagnus umbellata, Lonicera morrowii, Ligustrum vulgare, and Rosa multiflora are characteristic, along with Rubus spp. Herbaceous cover likewise varies. Common species in the more open-canopy stands include old-field denizens such as Schizachyrium scoparium, Festuca rubra, Anthoxanthum odoratum, Agrostis gigantea, Andropogon virginicus, Elymus repens, Solidago rugosa, Solidago gigantea, Euthamia graminifolia, Monarda fistulosa, Toxicodendron radicans, Achillea millefolium, and Daucus carota. In dense forest stands, herbs may be absent or limited to scattered shade-tolerant species such as Alliaria petiolata and Allium vineale, and Dennstaedtia punctilobula. These forests are often young and result from the colonization of old agricultural fields by Juniperus virginiana over native and exotic forbs and grasses. These stands may eventually succeed to other forest types as mid- and late-successional canopy species colonize and subsequently overtop the Juniperus.

Floristics: Juniperus virginiana dominates the canopy layer in stands of this type, which ranges from broadly-spaced woodlands to dense and nearly impenetrable thickets. Common associates, typically occurring as scattered individuals, may include Pinus strobus, Acer rubrum, Liriodendron tulipifera, Quercus spp., and Prunus serotina. Shrub cover varies according to canopy closure, with the most forested stands having little or no shrub cover. Exotic shrubs such as Elaeagnus umbellata, Lonicera morrowii, Ligustrum vulgare, and Rosa multiflora are most characteristic, along with Rubus spp. Herbaceous cover likewise varies. Common species in the more open-canopy stands include old-field denizens such as Schizachyrium scoparium, Andropogon virginicus, Festuca rubra, Anthoxanthum odoratum, Agrostis gigantea, Elymus repens (= Elytrigia repens), Solidago rugosa, Solidago gigantea, Euthamia graminifolia, Monarda fistulosa, Toxicodendron radicans, Achillea millefolium, and Daucus carota. In dense forest stands, herbs may be absent or limited to scattered shade-tolerant species such as Alliaria petiolata, Allium vineale, and Dennstaedtia punctilobula.
Dynamics: These forests are often young and result from the colonization of old agricultural fields by Juniperus virginiana over native and exotic forbs and grasses. These stands may eventually succeed to other forest types as mid- and late-successional canopy species colonize and subsequently overtop the Juniperus.
Environmental Description: This is a broadly defined old-field early-successional community occurring in a variety of environmental settings, typically on former agricultural land and other disturbed or degraded environmental settings. Soils are mesic to dry-mesic and moderately well-drained to well-drained.
Geographic Range: This association is of broad distribution, occurring widely throughout the northeastern U.S. It has been documented from only a limited range but is undoubtedly more widely distributed.
