Cal. Gov't Code § 27255

(a) The county recorder in each county shall develop and maintain, within the existing indexing system, a comprehensive index of conservation easements and Notice of Conservation Easement on land within that county. The conservation easement index developed and maintained pursuant to this subdivision shall include all conservation easements recorded on and after January 1, 2002.
(b) For the purposes of this section, “conservation easement” means any limitation in a recorded instrument that contains an easement, restriction, covenant, condition, or offer to dedicate, which is or has been executed by or on behalf of the owner of the land subject to that limitation and is binding upon successive owners of the land, and the purpose of which is to retain land predominantly in its natural, scenic, historical, agricultural, forested, or open-space condition. “Conservation easement” includes a conservation easement as defined in Section 815.1 of the Civil Code, an open-space easement as defined in Section 51075 of this code, and an agricultural conservation easement as defined in Section 10211 of the Public Resources Code.

(c) On and after January 1, 2002, when a county recorder records a new conservation easement affecting property within the county, he or she shall include the easement in the index developed and maintained pursuant to subdivision (a), if the document containing the easement is entitled “Conservation Easement,” or the following document is properly filled out by the submitter, and recorded at the same time, or at a later date:
