The Oregon Plant Atlas allows the user to generate customized plant distribution maps from herbarium specimen and observation data. The default search results displayed are “Flora vouchers”, specimens from the OSU Herbarium and selected vouchers from other herbaria. These serve as reference material for the upcoming Flora of Oregon. Any combination of available specimens or unvouchered observations can be mapped by selecting the appropriate checkboxes.
