A 30-year duty that outlasts everyone watching it.
Biodiversity Net Gain requires most development in England to deliver at least a 10 percent net gain in biodiversity, secured and maintained for a minimum of 30 years. In practice that obligation is checked by the occasional site visit, so a habitat can quietly degrade for years before anyone notices. Responsible bodies, councils and developers carry the risk and the scrutiny, with very little continuous visibility.
From plan to proof, in one place.
- 1
Bring in the plan or boundary.
Extract every parcel, its baseline and target condition, the target year and the management actions from a management plan, with the source clause recorded. Or upload an Area of Interest boundary file.
- 2
Set the required trajectory.
Each parcel gets the minimum condition it must hold each year, rising from baseline to target and then held.
- 3
Monitor from space.
Copernicus Sentinel-2 imagery estimates condition continuously; every parcel is classified on track, at risk or awaiting a baseline.
- 4
Verify on the ground.
Dispatch a field survey to a flagged parcel; the ecologist's geotagged assessment becomes the authoritative record and can confirm or override the satellite signal.
- 5
Prove it.
Export a timestamped, tamper-evident evidence pack for any parcel, with before and after imagery, the condition metrics and the management progress.
Built for the 30-year obligation, not generic mapping.
Explainable condition trajectory.
Every parcel measured against the curve it is contracted to follow, with the gap and the on track or at risk status shown.
Decision support, with authority intact.
Earth observation flags where to look; the ecologist certifies. The distinction is built in, which is what makes the evidence defensible.
Habitat change detection.
Before and after Copernicus Sentinel-2 imagery for any two periods, with a vegetation-change map confined to the parcel and synced pan and zoom.
Plan ingestion with provenance.
Pull parcels, targets and actions from plan documents, with the source clause kept for the evidence trail and a review step before anything is committed.
The whole portfolio, at any year.
A 30-year time scrubber to view the estate at any management year, with early warnings when a habitat slips behind.
Tamper-evident evidence packs.
Branded reports with timestamped imagery, metrics and progress, and a cryptographic integrity check so any alteration is detectable.
See the whole portfolio at a glance.
A satellite map shows every parcel coloured by status, alongside the 30-year time scrubber, filters, and layered views for condition, habitat, Earth observation recency and field verification. Open any parcel to see its trajectory, its before and after imagery and its evidence pack.
What good looks like.
Catch failures early.
Continuous monitoring flags a slipping habitat in months, not years.
Target scarce expertise.
Send ecologists exactly where the satellite says they are needed, so field budgets go where they matter.
Defensible compliance.
A complete evidence trail from plan clause to Defra Biodiversity Metric to a tamper-evident pack.
Lower monitoring cost.
Free, science-grade Copernicus data does the continuous watching, so there is no per-scene imagery bill.
Evidence-grade, and built to be trusted.
BioCoda holds long-term compliance data for real sites, so access control, audit and data residency are treated as acceptance gates.
- United Kingdom data residency.
- Least-privilege roles and database row-level security, so each organisation sees only its own data.
- Complete audit trail.
- Tamper-evident evidence packs, with a cryptographic integrity hash.
- Earth observation is decision support; field verification is authoritative.
