Outline of Quino Recovery Plan - The Xerces Society

should include, degree of nonnative species invasion, presence of local
threats.
5.8. Northwest Riverside Recovery Unit: Investigate the possibility of
remaining occupied or suitable habitat near the (now developed) Quino
checkerspot location near Murrieta (Figure 2).
6. Manage activity on trails where habitat occurs in recreational use areas,
particularly during the active season for Quino checkerspot larvae and adults (i.e.
November through May).
7. Locate or introduce two populations or metapopulations in the remaining
undeveloped coastal areas of the Quino checkerspot’s historic range.
Populations may be reintroduced experimental ones or newly documented.
8. Reduce fire frequency and illegal trash dumping in habitat areas.
Priority 3 recommendations:
9. Survey for habitat and undocumented populations in undeveloped areas
outside of Recovery Units.
9.1. Between the South Riverside/North San Diego Recovery Unit and the
Southeast San Diego Recovery Unit in eastern San Diego County, particularly
the slopes of the Laguna Mountains and the slopes of Mount Palomar.
9.2. Between State Route 94 and Interstate 8 in southern San Diego County.
9.3. In proposed Recovery Units.
9.4. The eastern slope of the Santa Ana Mountains, south of Lake Elsinore on
and around the vicinity of the Santa Rosa Plateau.
10. Survey other areas within Recovery Units (not covered by surveys to
determine the extent of metapopulation distributions) to determine whether there
is suitable habitat or undocumented populations.
10.1. Northwest and Southwest Riverside Recovery Units: Survey
undeveloped areas in the southern portion of the Recovery Unit.
10.2. Southwest and South Riverside Recovery Units: Survey areas between
the Brown Canyon site (near Hemet) and the Silverado and Skinner/Johnson
habitat complexes.
10.3. South Riverside/North San Diego Recovery Unit: Survey areas south of
the Silverado habitat complex and the Oak Grove site.
10.4. Southeast San Diego Recovery Unit: Survey areas west, north, and east
of the Jacumba habitat complex.
