Abstract

A technique has been developed that provides an on-the-spot field test to aid in identification of some sagebrush taxa. Seeds, dried or green crushed leaf material, or stem cambium of various sagebrush taxa will produce distinctive shades of blue when wet and placed under longwave ultraviolet light. The technique is particularly helpful in separation of Artemisia tridentata subsp. tridentata from A. tridentata subsp. vaseyana. Subspecies vaseyana extracts are blue, whereas those of subsp. tridentata are not. All taxa producing blue water extracts are preferred by mule deer.
