Maintain reestablished populations in Green River and upper <br />Colorado River subbasins, each> 4,400 adults" <br />. Maintain established genetic refuge of adults in lower basin <br />. Maintain two reestablished populations in lower basin, each > 4,400 <br />adults" <br /> <br />RECOVERY FACTOR CRITERIA <br /> <br />Upper Basin Recovery Unit <br /> <br />I.
