Developed and hosted by the University of Washington Herbarium at the Burke Museum, the web site brings together 71,806 photographs and contributions from numerous photographers and botanists.

Washington is home to an estimated 3,589 species of vascular plants, 2,453 species of macrofungi, and 1,191 species of lichenized fungi across a diverse array of landscapes from lush coastal rainforests to dry sagebrush plains, high alpine meadows and much more in between.

The Burke Herbarium and its partners have also released wildflower identification apps for Washington and Idaho based in part on content from the Burke Herbarium Image Collection. The macrofungal portion of the Image Collection web site reproduces photographs and species descriptions from Mushrooms of the Pacific Northwest, published by Timber Press.
