AB 900 directs the California Natural Resources Agency to prepare a dedicated stewardship section for the 2027 annual 30x30 progress report. The section must quantify stewardship backlogs and future needs, estimate associated costs, identify workforce and training gaps, evaluate benefits of stewardship, and recommend actions to expand and improve long‑term care of conserved lands.
The bill matters because it shifts attention from acreage targets to the practical work required to keep conserved lands functioning — including tribal partnership, ancestral land return, and the economics of long‑term management. For agencies, land managers, tribes, and funders, the report will frame priorities and surface where new investment or policy change is needed to make 30x30 durable on the ground.
At a Glance
What It Does
The bill requires the Natural Resources Agency to produce a stewardship section in the 2027 report that estimates stewardship needs and costs, reviews best practices and cobenefits, profiles workforce needs, and issues recommendations on funding, tribal partnership, and ancestral land return. It allows use of datasets that exist on or before March 31, 2027.
Who It Affects
State agencies (Natural Resources Agency lead), California Native American tribes and tribal land managers, state and local land managers, conservation NGOs, and workforce and training organizations involved in ecological management.
Why It Matters
AB 900 reframes 30x30 from a mapping exercise into an operational agenda: without sustained stewardship, protected acreage risks ecological decline. The mandated analysis will create a common evidence base for funding decisions and policy reforms tied to long‑term land care.

What This Bill Actually Does
AB 900 instructs California's Natural Resources Agency to tackle the often‑overlooked follow‑through on land conservation: stewardship. Rather than simply cataloging conserved parcels, the agency must prepare a stewardship-focused section for the 2027 annual 30x30 report that lays out what care those lands need, how much it will cost, who will do the work, and what practices produce the best outcomes.
To build that inventory the agency must estimate backlogged, critical, recurring, and future stewardship needs statewide and attach cost estimates. The bill authorizes the agency to use existing datasets—federal, state, local, tribal, and private—so long as those data exist by the March 31, 2027 cutoff.
The required contents extend beyond numbers: case studies, a best‑practices review that highlights new technologies, a valuation of biodiversity and ecosystem service benefits, and a frank assessment of workforce gaps and training opportunities.AB 900 also pushes the report to be action‑oriented. It asks for recommendations to increase stewardship capacity and funding across federal, state, and local levels, plus explicit proposals to advance ancestral land return and deepen consultation and partnership with California Native American tribes.
The bill requires public posting of the update on the agency’s website, and it defines stewardship broadly to include science‑based and traditional ecological management approaches—signaling an intent to blend Western science with tribal knowledge in stewardship planning.
The Five Things You Need to Know
The Natural Resources Agency must include a stewardship section in the 2027 annual 30x30 report mandated by Section 71452.
The agency must estimate backlogged, critical, recurring, and future stewardship needs statewide and attach cost estimates using datasets available on or before March 31, 2027.
The report must identify ecological workforce needs and opportunities to support workforce training for stewardship activities.
The bill requires recommendations on increasing ancestral land return and expanding consultation and partnership with California Native American tribes, including support for tribal stewardship and traditional ecological knowledge.
The stewardship update must be posted on the Natural Resources Agency’s website and defines 'stewardship' to include science‑based management, adaptive management, traditional ecological knowledge, and best land management practices.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Agency mandate to develop stewardship strategies
This subsection directs the Natural Resources Agency to develop strategies that reduce barriers and increase support for stewardship of conserved lands, tying that mandate explicitly to the Pathways to 30x30 findings that designate protection as only the first step. Practically, this creates a state‑level charge to move beyond acquisition metrics toward operational planning: the agency must identify obstacles (funding, workforce, legal constraints) and propose structural fixes to address them.
Estimate of stewardship needs and cost accounting
Subsection (b)(1) requires a statewide accounting of stewardship requirements—categorized as backlogged, critical, recurring, and future—paired with dollar estimates. The agency may draw on existing federal, state, local, tribal, and private datasets dated on or before March 31, 2027. This imposes a data‑integration task: reconciling disparate inventory approaches and defining consistent thresholds for what counts as 'critical' or 'backlogged' across land types.
Best practices, valuation, workforce, and cobenefits
These subsections require case studies of effective stewardship, a review of new technologies and practices, valuation of biodiversity and ecosystem service benefits, identification of ecological workforce needs, and a cobenefits review (recreation, carbon, water/air purification, etc.). The combined effect is to produce both qualitative and quantitative evidence to justify stewardship investment and to inform what training and tools managers will need to deliver those benefits cost‑effectively.
Recommendations, tribal partnerships, posting, and definition
The final group of provisions asks for recommendations to improve stewardship financing and implementation, to increase ancestral land return, and to expand consultation and partnership with California Native American tribes and cultural practitioners. It requires the update be posted online and defines 'stewardship' to include adaptive management and traditional ecological knowledge. These clauses formalize tribal engagement and public transparency as core components of any stewardship strategy the agency proposes.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- California Native American tribes — the bill requires recommendations and supports for tribal stewardship activities, traditional ecological knowledge, and ancestral land return, elevating tribes as partners in management rather than just consultees.
- Conserved land managers and conservation NGOs — they will receive a consolidated statewide needs assessment and best‑practice guidance that can justify funding requests and align on standards for stewardship.
- Ecological workforce and training providers — the mandated identification of workforce gaps creates a market signal for training programs, apprenticeship models, and job development tied to long‑term land management.
- State and local planners and funders — the cost estimates and valuations of ecosystem services give budget offices and grantmakers a data basis to prioritize investments and to argue for stewardship funding.
Who Bears the Cost
- Natural Resources Agency — the agency must compile, synthesize, and publish the stewardship section, which will consume staff time, analytic capacity, and potentially require contracting for valuation or data integration.
- Other state and local agencies, tribal and private data holders — the report relies on their datasets and collaboration; assembling and standardizing that data will impose coordination costs and time burdens.
- California Legislature and funders (potentially) — while AB 900 stops at analysis and recommendation, any implementation of identified stewardship needs will require new or reallocated funding, which will fall to the Legislature, bond programs, or agency budgets.
- Landowners and managers (private and local) — they may face new expectations to participate in stewardship planning, share data, or change practices if recommendations lead to regulatory or funding conditions.
Key Issues
The Core Tension
The bill confronts the central dilemma of 30x30 policy: expanding protected area totals is politically easier than funding the long‑term stewardship those areas require. AB 900 demands a rigorous inventory and recommendations but leaves the politically and financially hard work—who pays, who manages, and how tribal restitution is achieved—for later decisions, pitting conservation ambitions against fiscal and institutional realities.
AB 900 creates a necessary but unresolved first step: it requires a comprehensive diagnosis without allocating implementation resources. That makes the report potentially influential but not binding; lawmakers and agencies must still decide whether to fund the needs it surfaces.
The data cutoff (datasets in existence by March 31, 2027) accelerates the timeline but risks leaving important emerging data or local inventories out of the analysis, while forcing the agency to reconcile inconsistent methodologies across sources.
Operationalizing the bill's tribal partnership and ancestral land return recommendations raises difficult questions about legal mechanisms, funding, and timelines. The statute signals a preference for integrating traditional ecological knowledge, but it does not specify consultation standards, compensation for tribal stewardship work, or how land transfers would be structured.
Valuing ecosystem services and translating those valuations into budgetary lines is methodologically fraught; different valuation approaches could produce widely divergent cost‑benefit signals and influence funding priorities in ways the bill does not dictate.
