Boer in Natuur, Maashorst (Oncra BIN-N01-M01), home parcel

12.20 ha · food forest / agroforestry · NL · centroid 51.6948, 5.6013

Oncra registry project BIN-N01-M01: food forest and extensive grazing near Uden (Maashorst). Boundary is the public registry KML of the home parcel (12.2 ha of the 24.4 ha project). Registered by the operator as a worked example for carbon inference; the remover is not yet a steward here.

Seven readings

The verdict is the weakest of the seven. Unknown is a real answer: it says which stream still has to arrive.

Productivityfalling

capturing energy and building biomass (satellite greenness over the growing season)

confidence 100% · held 2 periods

single-place reading: the last growing season against the place's own previous three; regional weather (a dry spring, a wet summer) is not yet subtracted because the neighbour crowd is not built

Diversityunknown

differentiating into many forms (species heard per year)

confidence 0% · held 0 periods

no sound stream yet: install a recorder and deliver detections

Structureunknown

trophic levels and habitat complexity (acoustic indices)

confidence 0% · held 0 periods

no acoustic indices yet (NDSI/ADI); deliver indices or let the server compute them from detections

Renewalunknown

reproducing and recruiting (breeding-season song)

confidence 0% · held 0 periods

no sound stream yet: breeding-season song is the renewal signal

Cyclingunknown

closing water and nutrient loops (soil breathing from lab samples or a flux probe, corrected for moisture and temperature)

confidence 0% · held 0 periods

no soil stream yet: install a moisture and temperature probe and take a yearly lab sample

Resilienceunknown

recovering after shocks (drought years in the satellite archive)

confidence 20% · held 0 periods

fewer than two shocks (>15% below the place's median) in the archive; resilience cannot be read yet

Autonomyunknown

holding its state with little management (machine noise)

confidence 0% · held 0 periods

no machine-noise signal yet; anthrophony from indices or engine detections from the recorder

Each dot is one clear scene, cloud-masked with the scene classification layer, averaged over the pixels inside the boundary. Shaded bands are growing seasons.

Carbon, inferred (v0.1, a range, not an issuance)

Net ecosystem carbon balance per year: productivity from satellite greenness, minus soil breathing (from a temperature climatology until a probe exists), minus harvest export for this land use. Every parameter carries a low and a high value; the range is what the evidence supports. Credits would be issued for the lower bound. Method · JSON
