These maps use voucher specimen data from 7 herbaria in Washington and Oregon to construct a reasonably complete picture of the county-level distribution of Carex species in Washington State. Special thanks go to Fred Weinmann for compiling the 2058 records used here.

Work is underway on a Washington Carex Atlas that will include interactive specimen-dot maps. A beta version of these maps is now available online.

Enter your search criteria into the form below and click 'Retrieve Map' to view the distribution map. You can search by a full species name, by genus only, or by any part of a species name. Further search tips are provided below. The maps generated through this page are not linked to the WTU specimen database and are not interactive. Only Carex species are available through this query screen.
