The Distribution of Some Rare Coastal Lichens in the Pacific Northwest and Their Association with Late-seral and Federally-protected Forests

Lichen bioindication of biodiversity, air quality, and climate: baseline results from monitoring in Washington, Oregon, and California.

Heuristic Model for Identifying The Habitats of Erioderma Pedicellatum and Other Rare Cyanolichens in Nova Scotia, Canada

“…This situation is a result of difficulty in detecting lichen presence. Habitat models using Geographical Information Systems (GIS) have been successful in predicting sites of a variety of organisms including lichens (Glavich et al 2005a). A heuristic expert model was developed for a GIS application to provide predictive mapping for Erioderma pedicellatum and other rare cyanolichens in Nova Scotia.…”

Draft supplement to the 2004 final supplemental environmental impact statement to remove or modify the survey and manage mitigation measure standards and guidelines : Forest Service National Forests in Regions 5 and 6 and Bureau of Land Management districts in Washington, Oregon, and California within the range of the northern spotted owl

“…Twenty-three of these species are assumed to be assigned to one or more Agencies' SSSP Since the 2004 FSEIS, there have been additional publications (Geiser et al 2004, Geiser and Neitlich 2006, Glavich et al 2005a, b, Lesher et al 2003, Mote et al 2003, and one report (Glavich et al 2006) that provide evidence corroborating previous concepts of these species and expand understanding of distribution, number of populations in reserves, habitat requirements, and potential vulnerability to climate change.…”

“…New information for Usnea hesperina since the 2004 FSEIS better documents that its NWFP area distribution is limited to the marine fog belt within 15 km of the California, Oregon, and Washington coastlines to the northwest tip of the Olympic Peninsula, in western hemlock forests. There is suggestive evidence, based on randomly selected survey sites, that the lichen is primarily associated with forests in which the dominant trees are greater than 80 years of age (Glavich et al 2005a). Fourteen of the 27 well-documented populations in federal lands are in reserve allocations, but odds ratio tests based on results from randomly selected survey sites did not provide evidence that the majority of the NWFP area populations are in reserve land allocations (Glavich et al 2005a).…”
