Name: Rubus allegheniensis - Rubus canadensis Shrubland Alliance Reference: NatureServe Biotics 2019 Description: This alliance encompasses <i>Rubus</i>-dominated areas at high elevations in the Southern Blue Ridge, as well as related stands dominated by <i>Prunus pensylvanica</i>. This includes grassy balds (open montane grasslands), areas where the balsam woolly adelgid has caused <i>Abies fraseri</i> death, or other disturbed areas such as landslide scars that create open conditions. Stands of this alliance are dominated by <i>Rubus allegheniensis, Rubus canadensis</i>, and <i>Rubus idaeus ssp. strigosus</i>. Examples in otherwise grassy balds may also contain trace amounts of other species from adjacent grasslands, such as <i>Athyrium filix-femina ssp. asplenioides, Agrostis perennans, Angelica triquinata, Carex debilis var. rudgei, Carex brunnescens, Carex intumescens</i>, and <i>Rumex acetosella</i> (exotic). Successional stands at high elevation resulting from severe disturbance of spruce-fir forests (i.e., balsam woolly adelgid-affected stands), as well as exposed sites with other frequent, natural disturbance (such as shrub invasion of grazed fire meadows), may contain dense <i>Athyrium filix-femina ssp. asplenioides</i> and <i>Solidago glomerata</i> (on more protected sites). Scattered living trees and shrubs of <i>Amelanchier laevis, Betula alleghaniensis, Picea rubens, Prunus pensylvanica</i>, and <i>Sorbus americana</i> may occur.  Accession Code: urn:lsid:vegbank.org:commConcept:38131-{040225D1-CEA9-4197-A554-50D866735951} Plot-observations of this Community Concept: 0
