Abstract/Description: "In Oregon, palustrine systems account for 85% of wetland community diversity in the state, with lacustrine, riverine, and estuarine each representing 5%. Of palustrine systems, emergent classes account for 50% of the diversity of communities, followed by scrub-shrub (25%), forested (17%), aquatic bed (6%) and moss-lichen (0.4%). Rare plants and animals occurring in wetlands include 219 taxa in 11 life forms, listed in decreasing percentage of species: gastropods (30%), vascular plants (29%), fish (12%), insects (11%), birds (6.4%), bryophytes (6%), amphibians (2%), bivalves (2%), reptiles (0.9%), mammals (0.5%), amphipods (0.5%), flatworms (0.5%). The East Cascades ecoregion has the highest number of rare taxa, followed by the West Cascades and Basin and Range. High priority sites for ecoregions east of the Cascades center around lacustrine and palustrine elements."--Summary
