ยป Washington State County & Regional Species Lists


The species lists provided here cover Washington State's Vascular Plants at the county level and above. Each species entry in a list provides information about the species name and the year it was last collected in the county. The lists are based entirely on WTU's vascular plant specimen collections and are updated periodically as new specimens are added to our databases. In addition to the lists provided here, you can also create county-level species lists on the PNW Herbaria web site.

These lists should not be considered complete county floras; they are based solely on WTU's specimen collections. Although extensive, our representation of Washington's flora still contains gaps. You can help us fill the gaps by collecting and donating specimens to WTU. Further instructions can be obtained from David Giblin (wtu[at]u.washington.edu)


Follow the steps below to create your own customized species lists:

Step 1: Select one or more counties to include on your list:

There is no limit to the number of counties you can select; however, keep in mind that a list with many counties may take a while to download and may not fit nicely on a printed page (try printing in landscape mode ... more hints and tips).

Hints and tips for creating and printing lists:

- Our lists are formatted to look good when printed. however, you may need to adjust your browser's print settings to achieve the best possible printout:
  • For lists with more than 4 to 5 counties, try printing in landscape mode. Landscape mode can usually be selected in your printer's Page Setup dialog box - in your browser look in the File Menu for a Page Setup option. Users running Netscape on a Mac may not have this option.
  • Many web browsers remove background shading and images from a web page when printing. This will greatly affect the appearance of our printed lists. To force your browser to print backgrounds and images, use your browser's Print Preview menu option (if available) and select the appropriate choices given there.
  • Regional lists covering several adjacent counties provide much more complete species representations than do single-county lists.
  • File sizes for these lists can range from 100 KB for a single county to 4.2 MB for a list covering the entire state.
  • Most single county list includes anywhere from 200 to 1,100 names. Currently, our entire state list includes about 3,600 names (an over-estimate of the number of taxa since names are included at both specific and subspecific levels).
  • Some of our better represented counties include: King, Snohomish, San Juan, Clallam, Jefferson, Chelan, Kittitas, Yakima, Klickitat.
  • Our most poorly represented counties include those in southwest Washington (Wahkiakum, Cowlitz, Clark, Pacific) and southeast Washington (Walla Walla, Columbia, Garfield, Asotin). We encourage collectors to help us fill the gaps in our knowledge of these counties.
