What it is Filled
Forest inventory is the systematic collection and analysis of observations about forests within a defined area to estimate their extent, composition, condition and resources, with repeated inventories enabling assessment of change.
In scope
- Inventory objectives, target forest population, geographic coverage and reference period
- Forest definitions, land classifications and tree eligibility rules
- Sampling design, plot establishment and field or remotely sensed observations
- Estimation of forest attributes with uncertainty and coverage limitations
- Remeasurement, comparability and interpretation of forest change
- Inventory quality assessment and fitness for specified decisions
Out of scope
- The forest ecosystem and its ecological processes independently of their observation
- Forest management plans, harvesting prescriptions and operational execution
- Land ownership, tenure adjudication and access rights themselves
- Sensor engineering and generic geospatial data infrastructure
- Carbon credit issuance and greenhouse gas accounting beyond inventory-derived inputs
- Biodiversity surveys that do not form part of the inventory's stated objectives
Why it exists Filled
Enable an AI agent to recognise, assess and use a forest inventory by recording what forest population it describes, how observations support estimates and which decisions those estimates can justify.
Distinguishing features Filled
- Has an explicit target population, reference period and observation protocol, distinguishing an inventory from an informal forest description.
- Connects observations to reported forest quantities through enumeration or an explicit estimation method, distinguishing it from a collection of tree records.
- States whether outputs describe individual trees, stands, ownership units or larger reporting domains, preventing a tree census from being mistaken for a landscape estimate.
- Treats maps and remote sensing products as evidence with defined interpretation and validation requirements, rather than assuming a forest cover map alone establishes a complete inventory.
- Describes forest resources or conditions; recommendations for planting, thinning or harvesting belong to management activities that may consume its results.
What robots and AI may and may not do Filled
Must not
- Fabricate or alter inventory data.
- Use inventory data to plan illegal logging.
- Disclose locations of rare species or protected trees where publication puts them at risk.
- Present estimates as exact counts.
Only with a human decision
- Decisions on harvesting, protection or land use based on the inventory.
May
- Analyze forest inventory data with stated methods, sampling error and dates.
- Report national inventory results from official sources.
Moral aspects Filled
- Forest data drives decisions on conservation, carbon accounting and the livelihoods of forest communities.
- Indigenous and local communities hold rights and knowledge about forests.
Who is affected
- Forest communities
- Indigenous peoples
- Wildlife
Owners Filled
Steward
The forest owner or the national forest authority that runs the inventory.

Open questions
- Does the registry intend forest inventory to denote the observation activity, its resulting information product or both, and does an existing world model already cover that scope?
- Which authoritative inventory frameworks should ground the model, and how should their differing forest definitions be represented?
- Which attributes are essential across inventory purposes, and which require optional extensions for timber, biomass, biodiversity or forest health?
- What evidence and validation requirements should distinguish acceptable design-based, model-assisted and model-based estimates for different uses?
- How should inventories combining observations from multiple years express their reference period and eligibility for change assessment?
