Name: Limestone - Dolostone Talus Sparse Vegetation Reference: Midwestern Ecology Working Group... Description: This limestone-dolostone talus community is found throughout the central/upper midwestern United States, including the Ozark region, and adjacent Canada. Stands occur at the bases of steep cliffs along larger streams or rivers, or strongly dissected valleys. Aspect is variable, and moisture could be moist or dry. Soils are generally absent. Parent material could be limestone or dolostone with a mixture of rock fragments and large boulders. The vegetation is generally sparse but may vary depending on degree of slope, exposure (open versus shaded), and rock type. The composition of the type may be heavily influenced by adjacent forested stands. In Missouri, characteristic species include the ferns Adiantum pedatum, Diplazium pycnocarpon (= Athyrium pycnocarpon), Asplenium rhizophyllum (= Camptosorus rhizophyllus), and Cystopteris bulbifera. Other herbaceous species include Aralia nudicaulis, Impatiens capensis, Pilea pumila, Polymnia canadensis, and Physalis missouriensis. Scattered woody plants include Hydrangea arborescens and Staphylea trifolia. In Ontario open talus stands contain Adiantum pedatum, Ageratina altissima (= Eupatorium rugosum), Geranium robertianum, Impatiens capensis, Poa pratensis, and Toxicodendron radicans.  Accession Code: VB.CC.23700.LIMESTONEDOLOST Plot-observations of this Community Concept: 0
