<br />4.4 Complete research stockino of vreenbacks into waters with native ' <br />non-salmonids, or, introduce native non-salmonids to greenback <br />proiects. The purpose of this research is to evaluate the <br />opportunity for greenbacks and other native non-salmonids to <br /> <br />coexist, and to provide information on survivability of greenbacks ' <br />in lower elevation waters. One project has been completed at Lytle <br />Pond, U.S. Army, Ft. Carson, Colorado. In this project, Arkansas <br />darters were released in 1980, into an area occupied by greenbacks. <br /> <br />Both species were able to successfully coexist and have maintained ' <br />balanced populations since 1980. Other proposed projects include <br />evaluation of greenback survival with white suckers and creek chubs <br />in Monument Creek and Crow Creek. However, due to the proximity of <br /> <br />these streams to urban areas and the increased potential for harm to ' <br />any introduced greenbacks from increased human intrusion, these <br />projects may have to be completed after delisting to prevent <br />conflicts due to the current listed status of the subspecies. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />i <br /> <br />29 ' <br /> <br />
