Name: Appalachian Lichen Boulderfield Alliance
Reference: NatureServe Biotics 2019
Description: This alliance consists of large, dry, lichen-dominated boulderfields with little or no vascular vegetation, occurring in the eastern U.S. It occurs on a variety of sedimentary, metasedimentary and metamorphic substrates, including quartzite, sandstone and metabasalt. The dominant taxa vary across the range of the alliance. Some common combinations of lichens include <i>Lasallia papulosa</i> and <i>Lasallia pensylvanica</i> (either singly or together), <i>Lasallia papulosa</i> and <i>Lasallia caroliniana</i>, and <i>Umbilicaria mammulata</i>. Some other examples are dominated by <i>Umbilicaria muhlenbergii, Lasallia papulosa</i>, and <i>Melanelia stygia</i>. These are some of the most abundant and conspicuous lichens found in examples. Individual occurrences can be as large as an acre. Vascular plants are generally sparse or absent. In moister examples, trees of adjacent forest communities often shade the outcrop community for much of the day.
