The Influence of Microhabitat on Diversity Distribution and Abundance of Corticolous Lichens in Zion National Park, Utah and Navajo National Monument, Arizona
St. Clair LL, Rushforth SR, Brotherson JD. 1986. The Influence of Microhabitat on Diversity Distribution and Abundance of Corticolous Lichens in Zion National Park, Utah and Navajo National Monument, Arizona. Mycotaxon. 26:253-262
Decreasing aridity was found to have three major effects on corticolous lichens in Navajo National Monument and Zion National Park. 1. In dry habitats lichens were mostly found on north exposures of host trees, while in mesic habitats they occurred on all exposures. 2. Species diversity increased in more mesic habitats. 3. Total lichen cover increased in wetter habitats. Table 1: Average percent cover of lichen species by substrate and aspect at Betatakin Canyon, Navajo National Monument. Table 2: Average percent cover of lichen species by substrate and aspect at Zion Canyon, Zion National Park.
