Seven readings

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

Productivityholding
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 (water drawn by roots from the top 40 cm on dry days, against the day's evaporation)
confidence 0% · held 0 periods
no soil stream yet: install the moisture and temperature probes
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

Satellite greenness (NDVI), Sentinel-2

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
