Historical Land-Cover Evidence for EUDR

Historical evidence must establish a sequence

Historical land-cover evidence supports the EUDR assessment by showing the source area's earlier condition, later changes and relevant dates. The central question is whether qualifying forest converted to agricultural use after 31 December 2020. For wood, evidence must also address the separate harvesting-induced forest-degradation condition where applicable.

A current image or a recently issued supplier certificate cannot alone reconstruct that sequence. Use suitable dated observations and corroborating records linked to the actual production location. Distinguish what a source directly shows from what the reviewer infers.

The deforestation-free requirement explains why history matters. The Regulation's definitions supply the test, while the 2026 guidance discusses land-use evidence and the limits of administrative designations.

Build a baseline relevant to the cut-off

Identify evidence capable of showing whether the land met the forest definition around the relevant baseline. Record the area, tree characteristics and predominant land use, or the information supporting their assessment. A dataset's forest label may use a definition different from EUDR and needs interpretation.

An agricultural plantation can have substantial tree cover while being excluded from forest. Conversely, temporarily unstocked forest can remain forest in the relevant circumstances. Historical production and management records can help interpret what imagery alone appears to show.

Avoid a rigid assumption that only an image taken on 31 December 2020 can be useful. Appropriate observations from surrounding dates may contribute to the sequence, but the reasoning must explain what period they cover and whether an unobserved change could materially affect the conclusion.

Use several types of dated evidence

Image sequences can show visible change, while production records can indicate when farming began or which commodity occupied the land. Land registers and cadastral maps may support past use. Forest inventories and management plans can help explain forest type and temporary unstocked conditions.

Each source has limits. A planting record may establish that crops existed by a date without showing when forest was removed. A permit may show authorisation rather than completion. A current agricultural registration may record the result of conversion rather than the land's previous state.

Record source provenance, dates, boundaries and the facts established. Where information comes from a supplier, assess its reliability and consistency with independent evidence. The objective is not to collect the greatest number of documents, but enough suitable evidence to support the relevant conclusions.

Resolve gaps and uncertain dates

A pair of images can bracket a change without identifying its exact date. If the interval crosses the cut-off, obtain suitable additional evidence rather than automatically assigning the change to the earlier period. The significance of the gap depends on the facts and available corroboration.

Cloud cover, inconsistent resolution and seasonal vegetation can also create apparent changes. Compare observations and land-use context before concluding that forest converted to agriculture. An unexplained difference between two map products should prompt investigation of definitions and dates rather than a choice based on convenience.

Where uncertainty remains, describe it plainly in the risk assessment. An ordinary operator needs a supported no-or-negligible-risk conclusion before proceeding. An unverified supplier assurance should not be used to conceal a material period for which the evidence is genuinely inconclusive.

Keep historical boundaries and product links

Production areas can change through expansion, subdivision or corrected mapping. Retain earlier boundaries and the reason for each revision. A current polygon may not represent the area that produced an earlier batch, and a corrected boundary can change whether an observed conversion falls inside the relevant source.

For mixed properties, distinguish agricultural and qualifying forest sections as the guidance requires. The presence of longstanding farmland does not automatically establish the history of a newly added forest section. Assess new sourcing areas before they inherit the approved status of an older plot.

Connect the historical file to the goods through supplier, plot and batch records. Evidence for a cooperative district or a few sample farms cannot automatically establish the history of every actual plot supplying the relevant products. The source coverage of the assessment needs to remain explicit.

Consider imagery from 2019 and 2022 showing forest and then a plantation. Those observations establish a change within an interval but do not alone determine which side of the cut-off it occurred. A dated planting record, additional imagery or reliable contemporaneous land-use evidence may narrow the sequence. Assess whether each document concerns the same mapped area. A record for the wider property or a neighbouring field should not be treated as proof of the source plot's conversion date merely because the supplier name matches.

Write a conclusion that preserves the timeline

A useful record identifies the baseline, observations, changes, later use, evidence limitations and reasoning under the legal definitions. State separately whether the evidence supports the deforestation condition and any wood degradation condition. Keep lawful-production analysis distinct rather than treating a land title as proof of every issue.

The 2020 cut-off explanation helps separate the historical reference from later market application dates. A delayed business deadline does not move the years the land-history assessment needs to consider.

Review the timeline when new imagery, corrected boundaries or credible information changes the evidence. Preserve the earlier decision and the new reasoning so the business can explain both the original assessment and its response to later information.
