Name: Paronychia pulvinata - Silene acaulis Alpine Fell-field
Reference: NatureServe Biotics 2019
Description: This alpine association occurs on windswept alpine ridges and fell-fields throughout the southern Rocky Mountains. Most stands occur well above treeline. Slopes range from level to moderate (1-25%), and generally are on windward slopes (north- to west-facing aspects in the Southern Rockies). Total vegetation cover (vascular and nonvascular) rarely exceeds 40% and in some sites is closer to 25%, whereas rock, gravel and bare ground may cover 60% or more of a site. The vegetation occurs in mats, with few species growing on bare areas between the mats. Characteristic dominants include <i>Paronychia pulvinata, Minuartia obtusiloba, Trifolium nanum</i>, and <i>Silene acaulis</i>. Lichens and mosses have relatively high diversity and cover in this association. Stands of this association may cover large areas on windswept ridgetops, but less harsh microhabitats within the community will support small inclusions of alpine turf associations.
