These three maps depict species richness of the obligate cave fauna of the eastern United States. The maps are based on more than 5000 records of stygobites and troglobites in caves. The size of the larger hexagons is 3110 sq-km and the smaller hexagons are 778 sq-km. Hexagon grids were made available by Kevin Sahr, Department of Computer Science, Southern Oregon University.
