Coastal sage scrub in California and northern Baja California has been severely affected by urban expansion and is, in places, badly in need of restoration. We measured arthropod abundance and diversity on one of its primary components, the native shrub Artemisia californica (Asteraceae; California sage), to evaluate whether arthropod communities had become reestablished after a restoration attempt. We suggest that small-scale restoration attempts can be successful at restoring basic elements of surrounding biodiversity. They do create a different community, however, both taxonomically and functionally, and are at least initially less able to support rare species.
