Rare Epiphytic Coastal Lichen Habitats, Modeling, and Management in the Pacific Northwest

Predicting canopy macrolichen diversity and abundance within old-growth inland temperate rainforests

“…Temperature clearly plays an important role in predicting the presence or absence of old forest associate cyanolichens at a regional scale within ITR watersheds of the upper Fraser River. Glavich et al (2005) similarly pointed to temperature as a major predictor of cyanolichen presence or absence in coastal ''wet'' temperate rainforests, though across much larger regional scales.…”

“…Another community of particular concern for the maritime zone is the suite of rare and endemic lichen species restricted to a thin band of forest hugging the coastline (Glavich et al 2005b).

“…49), Leptogium brebissonii, Pseudocyphellaria perpetua, and Usnea hesperina. Habitat models built for these species do forecast a high sensitivity to climate fluctuation (Glavich et al 2005b). For sedentary organisms, successful range migration to cooler habitats at higher latitudes and elevations will depend on many factors.…”

Lichen refugia within sub-boreal spruce forests: The role of riparian alder swales.

“…Temperature has often been identified as an important variable in influencing lichen diversity (Pirintsos et al 1993;McCune et al 1997;Glavich et al 2005;Giordani 2006). Jovan and McCune (2004) found the greatest cyanolichen diversity in warmer, wetter sites, with maximum nitrophile diversity in warmer, drier sites.…”
