These maps are based on WTU's specimen holdings. Because we have entered at least one specimen per county per species, these maps will highlight all the counties in Washington for which WTU has at least one specimen (and make apparent the gaps that could be filled in). Caution: The maps generated through this page do not represent complete species range maps. They show only those counties for which WTU has specimens for the name you enter
