Mapping and Treating Gravel Pits

The Cook County Invasive Team has identified gravel pits as high priority areas for invasive species control based on their ability to serve as vectors of invasive species dispersal.

Gravel pits provide the disturbed habitat many of Cook County's invasive species thrive in and once these species become established in gravel pits, they can be dispersed throughout the county as seeds taken up in the gravel. Based on this high potential for rapid and long-distance dispersal the CCIT has decided to inventory and treat many of the gravel pits in the county.


The following figure shows the 127 known gravel pits in the county based on the data supplied by Cook County and the Minnesota. Department of Transportation (note some of the gravel pits appear to be in Lake Superior due to the rough GPS coordinates provided).
