CRATER LAKE National Park Checklist Of Vascular Plants

A Checklist Of Vascular Plants of Crater Lake National Park Oregon CONTENTS Table of Contents Introduction Legend Plant Index References

This checklist includes approxiamately 700 plant taxa found within the boundaries of Crater Lake National Park (CRLA). The primary source for taxonomic nomenclature and habitat preferences was "Compiling an annotated checklist of vascular plants in Crater Lake National Park, Oregon" by Peter F. Zika (1996), a comprehensive report contracted between the National Park Service and The Nature Conservancy. Cross references were made to The Jepson Manual: Higher Plants of California (Hickman 1993) and Flora of the Pacific Northwest (Hitchcock & Cronquist 1973).

Families and scientific names are listed alphabetically within each of the four major groups [ferns and fern allies, gymnosperms, dicots, and mononcots]. Scientific names (including subspecies and varieties) are followed by one or more common names. A question mark (?) appears if a name is questionable or not known.

The STATUS column identifies rare plants and non-natives. Three (3) species are listed as endangered (E), threatened (T), species of concern (SC), or candidate for listing (C) by federal (F) and/or state (S) government and, therefore, are protected under the Endangered Species Act of 1973 and/or the Oregon Endangered Species Act of 1987. Furthermore, fourteen (14) species are considered rare or of special concern by the Oregon Natural Heritage Program (O). Forty-nine (49) plants are considered non-native or exotic (*) to the park.

Seven general habitats, each of which incorporates a number of microhabitats, are listed in the tables. An individual species may prefer one or more habitats or microsites. An X in the column denotes a species' preference.

The following sample entry from the checklist indicates that Apocynum androsaemifolium has no special Status and that it may be found in Dry, Forested and /or Open sites, Disturbed areas, or in a habitat with some combination of these characteristics.
