Oregon Natural Heritage Information Center

A list of rare, threatened or endangered invertebrates of Oregon which includes for each taxon: scientific name, common name, Heritage Global Rank, Heritage State Rank, Federal Status, State Status, Heritage List number, Oregon county distribution, Oregon ecoregion distribution, and other states or provinces in which it has been reported to occur.

Global and Stank Heritage Ranks follow the Heritage ranking protocol of NatureServe and outlined on their web site (http://www.natureserve.org/explorer/ranking.htm).

Notations in ranks: G = global, H = historic record, NR = unknown, Q = questionable taxon, S = state, T = subspecific rank

Federal Status is from the U.S. Fish and Wildlife Service.

Counties listed in the Oregon County Distribution column have been culled from known occurrences, literature or reputable sighting reports or personal communications. If ORNHIC found the information unclear then a question mark was denoted after the county name.

Ecoregion distribution information is based on the map developed by: Thorson, T.D., Bryce, S.A., Lammers, D.A., Woods, A.J., Omernik, J.M., Kagan, J.S., Pater, D.E. and Comstock, J.A., 2003. Ecoregions of Oregon. More information and a digital copy is available at http://www.epa.gov/wed/pages/ecoregions/or_eco.htm

NatureServe Explorer (http://www.natureserve.org/explorer) was used to gather information for State and Province distribution listed in the Other States column.

The 2004 list of rare invertebrates includes updates resulting from review and ranking of the Northwest Forest Plan's "Survey and Manage" taxa. A number of taxa were also added to the list.
