The Lichen Flora of the Spring Mountains, Humboldt-Toiyabe National Forest, Nevada, USA

Abstract

124 lichen species in 48 genera are reported for the Spring Mountains, Clark and Nye Counties, Nevada. The Spring Mountains are a sky island mountain range in the Mojave Desert located approximately 25 km northwest of Las Vegas. This species list includes 58% of the 217 species in 68 genera reported to date for the Mojave Desert. This survey was based on extensive collections made between 1997 and 2007 as part of an air quality bio-monitoring program and baseline established in the Spring Mountains, Humboldt-Toiyabe National Forest. This report represents a major contribution to our understanding of the lichen flora of Nevada in particular and the Mojave Desert in general.
