UNTIL A CORRECTION OF THE FINAL RULE IS PUBLISHED THE BOUNDARIES OF UNITS 8, 10, 11 AND 14 SHOULD BE CONSIDERED PROVISIONAL. These data reflect revisions to the proposal published in the Federal Register on October 13, 2009 (74FR52614). Critical habitat for the species consists of approximately 98,000 acres among 22 units from San Diego County northward to Santa Barbara County, California. Descriptions of the units and all area calculations contained in the rule published in the Federal Register on February 9, 2011 (76FR7246) are consistent with the boundaries contained in this data set.
