(Authors' abstract.) Lichen community structure was examined on silicious rocks in the Brooks Range near Anaktuvuk Pass. Rocks with 00 slope were the most variable with respect to crustose, foliose, and fruticose growth forms. Foliose lichens were the most common growth form of 00 slopes, with Parmelia stygia accounting for about 14% of the cover. Foliose lichens also dominated the 300 slopes, with P. stygia accounting for 23% of the cover. Crustose and foliose lichens were equally common on 600 slopes, with P. almquistii accounting for 32% of the cover. Vertical surfaces were dominated by crustose species of which Sporastatia testudinea, with 8% cover, was the most common species.
