Abstract

This study presents a new approach designed to record lichen species on rock outcrops. Terrestrial laser scanning (TLS) offers a new technique for recording individual lichen species (e.g., abundance, spatial distribution, extent, size, shape). An automated process is described to extract the lichen extent and shape in a standard GIS environment. These data are used to examine 6 classes, frequency, per-cent cover, and spatial pattern of a species of Phlyctis. The methodology and data extracted greatly improve rapid assessments and long-term monitoring of lichen populations
