SB 1397 California Senate · 2025-2026 Regular Session

Mountain Lions: human-mountain lion conflicts program: scientific research.

Summary
Proposition 117, an initiative measure approved by the voters at the June 5, 1990, statewide primary election, enacted the California Wildlife Protection Act of 1990. The act classifies the mountain lion as a specially protected mammal under the laws of this state, and makes it unlawful to take, injure, possess, transport, import, or sell any mountain lion or any part or product thereof. The act authorizes the take of mountain lions under limited circumstances, including by authorizing the Department of Fish and Wildlife, or an appropriate local agency authorized by the department, to remove or take any mountain lion that is perceived to be an imminent threat to public health or safety. Existing law permits the department, as the department determines is necessary to protect mountain lions or the public, to authorize qualified individuals, educational institutions, governmental agencies, or nongovernmental organizations to implement nonlethal procedures, which are defined as procedures that may include, among other things, capturing, pursuing, or hazing mountain lions. Existing law permits the department to authorize qualified individuals, educational institutions, governmental agencies, or nongovernmental organizations to conduct scientific research involving mountain lions pursuant to a scientific collecting permit, as specified. This bill would require the department, contingent upon an appropriation by the Legislature, to maintain, enhance, and expand its human-mountain lion conflicts program in a specified region of the state in order to protect public health and safety, including by exercising its authority to authorize nonlethal procedures. The bill would require the department to continue and expand its scientific research effort to develop and evaluate methods to deter mountain lions from entering communities and to prevent habituation to humans. In implementing these programs, the bill would require the department to engage in specified public outreach activities in a specified region of the state. The bill would repeal these provisions on January 1, 2033. The bill would require the department to prepare and submit a report to the Legislature on or before October 1, 2031, describing these programs, the results of the programs, the number of department personnel involved in the programs, and recommendations to further improve the programs to protect human health and safety. The bill would require the Director of Fish and Wildlife, when requested, to appear before the appropriate policy or budget committees of the Assembly and Senate to provide a status update on the programs. The California Wildlife Protection Act of 1990 prohibits the Legislature from changing the act, with specified exceptions, except by a 45 vote of the membership of both houses of the Legislature and then only if consistent with, and in furtherance of, the purposes of the act. This bill would declare that it is consistent with, and furthers the purposes of, that act.

05/14/26 - Amended Senate 07/01/26 - Amended Assembly · 4 edits · Jul 1, 2026
MODERATE
The Assembly amended SB 1397 to narrow the geographic scope of community engagement requirements from statewide or multi-county areas to the single region identified by the department, and to weaken the legislative oversight mechanism by replacing a mandatory annual director appearance before specific committees with an on-request basis before broader policy or budget committees. These changes reduce the bill's accountability provisions while keeping the core program structure intact.
SCOPE

Section 4811.4(a) changed from requiring the department to work with community and local leaders 'across the state' to working only in 'the region identified pursuant to subdivision (b) of Section 4811,' narrowing outreach to a single region rather than statewide.

Section 4811.4(b) changed from requiring attendance at public meetings in 'counties with high human-mountain lion conflicts' to attending only in 'the region identified pursuant to subdivision (b) of Section 4811,' further concentrating the requirement on one region.

ENFORCEMENT

Section 4811.6(a) replaced a mandatory annual appearance by the director before the Senate Committee on Natural Resources and Water or the Assembly Committee on Water, Parks, and Wildlife (until 2034) with a requirement to appear 'when requested' before 'the appropriate policy or budget committees of the Assembly and Senate.' This removes the guaranteed yearly check-in and gives committees discretion over whether to request an update.

TECHNICAL

Minor grammatical fix in Section 4811(a) removing a stray 'The' before 'Contingent upon an appropriation by the Legislature.'
