About this Map
This map shows where the plant Conyza canadensis 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 on an island the island is shown in the normal color. Otherwise, the island just gray. The data displayed in this map is incomplete and occasionally contains errors.
