The Restoration Project was implemented in accordance with the Diegan Coastal Sage Scrub Restoration Plan, TransNet EMP Grant Project: Calavera Preserve Planning Area (Restoration Plan), which was prepared by Technology Associates, Inc. (TAIC) (Aug. 24, 2009). The goal of the project was to restore 5 acres of non-native grassland habitat to Diegan coastal sage scrub that is (a) self-sustaining, (b) suitable habitat for the California gnatcatcher, and (3) free of non-native invasive species that could invade adjacent native habitat. In addition to habitat restoration, the City of Carlsbad had an active public outreach program highlighting the benefits of natural open spaces throughout the city.
