Eight Additional Weeds Mapped By QuarterQuad:
The maps below do not depict the statewide distribution and abundance of these eight weed species. Although the Colorado Department of Agriculture has not yet requested statewide data for these particular species, some county weed managers have volunteered this data and we have assembled the information here. These maps will continue to be updated as local jurisdictions provide additional data. If and when the Department endeavors to gather statewide data for these species, these maps will be moved to the list above.
