Fish & G. Code, § 2722

(a) Whenever the application of the criteria specified in Section 2721 results in the identification of two or more parcels of land that are essentially indistinguishable as to their quality, preference shall be given to the parcel on which exists the species that is more threatened or more endangered.

(b) Whenever the application of the criteria specified in Section 2721 results in the identification of two or more parcels of land that are essentially indistinguishable as to their quality and the degree of threat to, or endangerment of, the species existing on them, preference shall be given to the parcel on which exists the best example of the species. As used in this subdivision, “best example” means the parcel of land and the wildlife inhabiting it which, in balancing all the factors present, represents, as determined by the board, the stronger combination of all of the following: the better condition, higher quality, easier defensibility, greater likelihood of long-term viability, and the lesser costs to be incurred by the department in operating and maintaining the parcel.
