Student volunteers collecting herbarium specimens in the Arboretum

The Otis Douglas Hyde Herbarium collects and houses pressed specimens of accessioned plants in the UW Botanic Gardens, as well as specimens that reflect the research of students, staff and faculty. In addition, the Washington State Noxious Weed Control Board’s collection is located in the Hyde Herbarium.

These collections are vital to science. Herbarium specimens provide information about plants in our past and present environments. They offer a view over decades and centuries that allow scientists to study the extinction of plants, track invasive species, and even shed light on climate change through phenology (the study of cyclic and seasonal natural phenomena, especially in relation to climate and plant and animal life). The Hyde Herbarium is a storehouse of botanical DNA from the Seattle region, the Pacific Northwest and beyond.
