Locality: Great Basin National Park, Nevada, USA
Abstract: Lichen communities in many National Parks are diverse and perform essential but often poorly understood ecological roles. However, lichen species diversity in most National Parks is poorly known. Because of this, limited interpretive resources are currently available. Here we report a preliminary checklist of the lichen species found in Great Basin National Park (GBNP), White Pine County, Nevada, USA, including 233 species in 84 genera, identified predominantly from recent field surveys. While our study documents an impressive diversity of lichen species for the Park, we anticipate that a significant percentage of the lichen flora remains to be discovered. Our hope is that this preliminary checklist will provide effective support and direction for additional work in GBNP.
