Purpose and description
Enable an agent to recognise and assess deforestation under an explicit forest definition, distinguish it from other forest changes, and identify justified prevention, verification or response actions.
Deforestation is the conversion of forest to another land use or a lasting loss of forest status, with operational definitions differing in their land-use criteria, canopy thresholds and treatment of plantations.
It can be Classify a candidate conversion under one or more explicit definitions and explain disagreements.; Compare gross converted area across periods or places after checking methodological compatibility.; Request targeted observations that distinguish conversion from temporary disturbance or degradation.; Trace evidence-supported conversion pathways while preserving uncertainty about actors and causes.; Assess a conversion against an applicable cut-off date, legal rule or land-use commitment.; Identify prevention or remediation options whose authority, feasibility and expected effects require verification..
Distinguishing features
A candidate area must qualify as forest before the transition under the selected definition; clearing land already classified as non-forest does not establish deforestation.
Canopy loss alone is insufficient: classification requires evidence meeting the selected rule for conversion to non-forest.
Temporary disturbance and persistent conversion must be separated using subsequent land use, regeneration evidence and the applicable time horizon.
A forest may lose ecological quality while remaining forest under a selected definition; such degradation must not automatically be classified as deforestation.
Forest gains elsewhere must be recorded separately from gross deforestation so that net forest-area change does not conceal conversion.
Scope
+ Definitions of forest and deforestation, their proponents, intended uses and operational thresholds
+ Candidate forest-to-non-forest transitions and evidence supporting or disputing their classification
+ Extent, timing, persistence and subsequent land use of forest conversion
+ Direct conversion activities, underlying pressures and attribution uncertainty
+ Consequences attributable to conversion and conditions for prevention, cessation or remediation
- Forest ecosystem description independent of conversion
- Forest degradation or canopy disturbance without a qualifying transition to non-forest
- Afforestation, reforestation and restoration programme design beyond their relationship to a conversion
- Complete agricultural, mining, infrastructure or commodity production models
- General land tenure, environmental law and carbon accounting systems
Characteristics
- Applicable definition
- Named authority or research approach, definition version, purpose and jurisdiction The same observed change may receive different classifications under different definitions.
- Forest eligibility thresholds
- Minimum area in hectares, canopy cover in percent, tree height in metres, land-use rules and exclusions Establishes whether the pre-conversion area qualifies as forest.
- Transition classification
- Suspected conversion, confirmed deforestation under a named definition, temporary disturbance, degradation, non-qualifying change or unresolved Separates observed change from the interpretation assigned to it.
- Pre-conversion forest condition
- Recorded forest origin, management status and condition, including unknown values Supports eligibility assessment and prevents unlike forest conversions from being treated as equivalent.
- Gross converted area
- Hectares within a specified boundary and observation period, with uncertainty Measures conversion without subtracting unrelated forest gains.
- Conversion timing
- Earliest and latest supported dates; observation dates recorded separately Supports temporal attribution and comparison with relevant cut-off dates.
- Persistence and regeneration
- Persistent non-forest use, regeneration observed, regeneration expected but unverified, or unresolved; assessment horizon specified Helps distinguish conversion from temporary disturbance without treating future intentions as observed recovery.
- Post-conversion land use
- Agriculture, pasture, settlement, infrastructure, extraction, other specified use or unknown Provides evidence of conversion and informs plausible causes and responses.
- Conversion attribution
- Supported links to activities, actors and underlying pressures, with evidence strength Distinguishes causal evidence from proximity, ownership or commercial association.
- Evidence confidence
- Method-specific confidence or uncertainty, conflicting observations and unresolved alternatives Determines whether a claim supports monitoring, investigation or a consequential decision.
- Legal or commitment assessment
- Not assessed, compliant, non-compliant, disputed or undetermined under a named applicable rule Separates the occurrence of deforestation from its treatment under law or a voluntary commitment.

Forest and conversion definitions Establishes the meaning under which an observed landscape change counts as deforestation.
A defensible classification requires an explicit definition rather than an assumed equivalence between tree loss and deforestation.
Forest eligibility
Determines which pre-change areas qualify as forest.
Forest definition and holder
Record the authority or school using each definition, its purpose, thresholds and treatment of managed or tree-covered land.
- Whose forest definition governs this assessment, and which version and purpose apply? definition
- How does that definition treat plantations, agroforestry, temporarily unstocked land and naturally sparse tree cover? boundary
Conversion boundary
Separates qualifying conversion from disturbance, degradation and changes in forest type.
Competing conversion rules
Record whether each approach relies on land use, land cover, persistence or another criterion, retaining disagreements between classifications.
- What combination of land-use change, canopy change and persistence makes an instance qualify as deforestation? definition
- Would conversion of natural forest to a tree plantation receive different classifications under the approaches being compared? boundary
- Does the selected approach require human causation, and how does it treat lasting forest loss after natural disturbance? boundary
Conversion evidence and history Builds the supported history of a candidate forest-to-non-forest transition.
A change alert becomes a deforestation assessment only when its baseline, interpretation and subsequent trajectory are examined.
Baseline and detection
Establishes pre-change forest status and the observations indicating a transition.
Supported before and after state
Connect the classification to dated imagery, field observations or land-use records, including limits on what each observation establishes.
- Which dated observations establish that the area qualified as forest before the suspected conversion? provenance
- What evidence establishes non-forest conditions or use rather than merely a canopy-loss signal? measurement
Persistence and sequence
Reconstructs the trajectory before and after canopy loss or land-use change.
Disturbance or lasting conversion
Record the event sequence, regeneration observations and remaining alternatives without assuming a single observation establishes permanence.
- What sequence of clearing, burning, cultivation, construction or regrowth is supported by observations? provenance
- Over what period must subsequent use or regeneration be observed to resolve the classification under the selected rule? measurement
- Which additional observation would distinguish temporary disturbance from persistent conversion? action
Extent and accounting Measures conversion consistently across spatial boundaries, time periods and observation methods.
Reported deforestation can change with resolution, denominators and accounting choices even when the underlying landscape history is unchanged.
Spatial and temporal extent
Defines the conversion footprint and the interval in which it occurred.
Conversion footprint and date
Record mapped area, boundary uncertainty, event-date intervals and detection limits.
- What area meets the conversion criteria, and how do spatial resolution and minimum mapping area affect the estimate? measurement
- What are the last supported forest date and first supported non-forest date, and how do these differ from the alert date? measurement
Aggregation and comparability
Controls how individual conversions become landscape or period statistics.
Gross loss and rate basis
Keep gross deforestation separate from net forest change and specify denominators, repeated observations and methodological breaks.
- Does the reported quantity measure gross deforestation, tree-cover loss or net forest-area change? boundary
- Which baseline forest area and time interval define any percentage or annual rate? measurement
- How are overlapping detections, repeated clearing and changes in mapping method handled before comparing totals? measurement
Drivers and responsibility Explains how conversion occurred and which actor relationships are supported.
Prevention and accountability depend on separating observed conversion activities from inferred motives, enabling conditions and responsibility.
Conversion pathways
Relates the immediate physical changes to subsequent uses and underlying pressures.
Direct and underlying drivers
Distinguish observed clearing mechanisms and destination uses from hypotheses about economic, institutional or access-related pressures.
- Which activity directly produced the transition, and what evidence links it to the subsequent land use? provenance
- Which underlying pressures are supported by evidence, and which remain competing explanations? provenance
Actor and rule attribution
Separates land relationships, operational control and applicable obligations.
Supported responsibility and status
Record evidence for who conducted, authorised or influenced conversion, separately from ownership and compliance conclusions.
- What evidence distinguishes the landholder, rights holders, clearing operator, authorising body and any linked buyer? provenance
- Which rule, jurisdiction and effective date support any legal or commitment-related classification? boundary
- What unresolved attribution or tenure issue must be investigated before assigning responsibility? action
Consequences and response Connects a supported conversion assessment to its consequences and feasible actions.
Converted area alone does not establish ecological or social harm, nor determine which response is justified.
Conversion-specific consequences
Identifies changes attributable to the conversion and the limits of available evidence.
Ecological and social effects
Record supported effects on habitat, carbon stocks, water, soils and forest-dependent people, referring detailed assessment to neighbouring models.
- Which consequences were measured locally, which were estimated, and what baseline or counterfactual supports attribution? measurement
- Which habitats, connections, resources or customary uses were affected, and whose evidence is represented? provenance
Intervention and follow-up
Determines the next justified action and how its outcome will be checked.
Stage-appropriate response
Distinguish threatened, ongoing and completed conversion when evaluating prevention, cessation, investigation or remediation.
- Is conversion threatened, ongoing or completed, and which actions remain feasible with the relevant authority and rights-holder participation? action
- What observations would demonstrate reduced conversion or recovery, including possible displacement of clearing elsewhere? measurement
- Which consequences may remain after tree cover returns, and how should they constrain claims of remediation? boundary
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

Neighbouring kinds and how to tell them apart
Recalled without web access and unsourced; every item is a lead to verify.

- tree-cover loss - Tree-cover loss is a biophysical observation that can include harvesting, fire or plantation turnover without lasting forest conversion.
- clear-cutting - Clear-cutting is a harvesting method; it constitutes deforestation when followed by lasting conversion rather than forest regeneration.
- net forest area change - Net change balances forest gains against losses; deforestation measures conversion losses that gains elsewhere can conceal.
- afforestation - Afforestation establishes forest on land previously under another use, reversing the direction of land-use conversion.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of deforestation this model covers, and on what evidence? provenance
What the second pass must settle
- Which named institutional and research definitions should anchor this model, and where do their treatments of plantations, agroforestry and natural disturbance diverge?
- Which observation horizons and evidence standards adequately distinguish temporary disturbance from conversion across different forest types and management systems?
- How should the registry's XCT / XCT.STA placement represent the distinction between a conversion process, a completed event and the resulting non-forest state?
- Does an existing Vercy world model already own this concept, requiring the registry entry to link to that publication?
- What minimum evidence should support actor attribution and consequential response decisions when land rights, conversion timing or subsequent use are disputed?
