The Legislature further finds and declares that the cooperation of the owners of land which is identified as habitat for endangered species and threatened species is essential for the conservation of those species and that it is the policy of this state to foster and encourage that cooperation in furtherance of the purposes of this chapter. Therefore, a landowner of property on which an endangered, threatened, or candidate species lives shall not be liable for civil damages for injury to employees of, or persons under contract with, the department if the injury occurs while those persons are conducting survey, management, or recovery efforts with respect to those species.
