11. Enter into dialogue with Baja California, Mexico nongovernmental organizations and local governments. Discussion topics include beginning surveys to determine the extent of the Otay foothills, Marron Valley, and Jacumba habitat complex population distributions across the border, and discussing possible protective measures for all Mexican populations. 12. Enter into dialogue with the Cahuilla Band of Mission Indians. Discussion topics include investigating the extent of the Silverado habitat complex population distribution within the Cahuilla Indian Reservation and possible protective measures. D. Preliminary Recommendations for Proposed Recovery Units Proposed South-central San Diego Recovery Unit: 1. Map distribution and suitability of habitat. 2. Restore vernal pools and other habitat where needed. 3. Survey for butterflies in the highest-quality habitat sites during years of confirmed high Quino checkerspot density in nearby reference metapopulations. 4. Maintain connectivity with undeveloped areas to reduce indirect impacts of development. 5. Determine habitat distribution and landscape connectivity potential in undeveloped areas between the Recovery Unit and the Laguna Mountains. Proposed Northwest San Diego Recovery Unit: 6. Map distribution and suitability of habitat. 7. Conduct focused surveys for butterflies in the highest-quality habitat sites during years of confirmed high Quino checkerspot density in Riverside County reference populations. 8. Determine what military activities are most likely to affect Quino checkerspot populations and how best to minimize conflict between metapopulation management and essential ongoing military training. 9. Determine extent of imported fire ant (Solenopsis invicta) distribution and possible impacts on the native community. 10. Determine extent of landscape habitat connectivity with Proposed North Orange Recovery Unit through the eastern slope of the Santa Ana Mountains. Proposed North Orange Recovery Unit: 77
11. Protect the remaining undeveloped suitable habitat areas in higher elevations. 12. Remove cattle grazing from Black Star Canyon and phase in weed control. 13. Restore habitat around Irvine Lake and reintroduce the Quino checkerspot. 14. Determine extent, suitability, and landscape connectivity of habitat along the western slope of the Santa Ana Mountains south of the Recovery Unit as far as the proposed Northwest San Diego Recovery Unit.. 15. Conduct focused surveys for butterflies in the highest-quality habitat sites during years of confirmed high Quino checkerspot density in reference populations. 16. Determine extent of imported fire ant distribution and possible impacts on native communities. 78
