About this Map
This map shows where the plant Astragalus shortianus has been found. When a plant has been collected at a specific place there is a blue dot on the map. When many plants have been collected the color of the dot is made darker, then redder. When there is a record of the plant growing in a county the county is shown in the normal color. Otherwise, the county has a white overlay. The location search algorithm assumes the plant will never be found in areas with crosshatching. The data displayed in this map is incomplete and occasionally contains errors.
