Significant Ecological Areas

Delineation of SEAs

The methods used to identify and delineate proposed SEAs was multi-faceted, including: a ten year broad outreach program focusing on government resource agencies, academic institutions, conservation groups, and the general public; a comprehensive database and literature review; an evaluation of existing SEAs in the unincorporated County; the interpretation of aerial photography; and, field study and ground-truthing. A detailed description of the methodology and initial outreach program is located in the SEA Update Study 2000 Background Report.
