Name: Impatiens pallida - Cystopteris bulbifera - Adoxa moschatellina Algific Talus Rock Vegetation Reference: NatureServe Biotics 2019 Description: The algific talus slope community type is found in the Driftless Area (Paleozoic Plateau) of the upper midwestern United States. Stands occur at the base of steep north-facing dolostone talus slope adjacent to maderate cliffs. Continuous cold-air drainage from fissures and ice caves in the talus creates a cool, moist microclimate that keeps summer temperatures from rarely exceeding 16°C, and winter temperatures rarely below -10°C. Exposed talus and boulders may be common. Stands vary in size from a few m square to narrow linear complexes that extend up to 1.5 km, depending on their geology. The vegetation is dominated by forbs, ferns, and mosses, which cover much of the talus. The most abundant species are <i>Adoxa moschatellina, Circaea alpina, Cornus canadensis, Cystopteris bulbifera, Impatiens pallida, Maianthemum canadense, Mertensia paniculata</i>, and <i>Mitella nuda</i>. Other characteristic species include <i>Aconitum noveboracense</i> and <i>Chrysosplenium alternifolium var. sibiricum</i> (a boreal disjunct). <i>Carex norvegica</i> is reported in Wisconsin. Associated shrub and tree species include <i>Abies balsamea, Acer spicatum, Betula papyrifera, Fraxinus nigra</i>, and <i>Rhamnus alnifolia</i>. Relict and disjunct vascular plants found only on algific talus slopes include <i>Aconitum noveboracense</i> and <i>Chrysosplenium alternifolium var. sibiricum</i>. Among the land snails, the same is true for <i>Discus macclintocki</i> and <i>Vertigo brierensis</i>, whereas others occur mostly on algific talus slopes, including <i>Catinella gelida, Vertigo hubrichti ssp. hubrichti</i>, and <i>Vertigo iowaensis</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:31295-{71F348DD-444F-4D8F-8A99-F589507152BA} Plot-observations of this Community Concept: 0
