Demo peat meadow, Zegveld
18.59 ha · peat meadow · NL · centroid 52.1412, 4.8415
Demonstration place: peat meadow polder land near Zegveld (Groene Hart). Registered by the operator to show the satellite stream on peat; no steward on record yet.
Verdict · 2026-Q3
Insufficient data
unknown: diversity, structure, renewal, cycling, resilience, autonomy
Streams
- Satellite: 472 clear observations, 2019-01-03 to 2026-09-01

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 1 period
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 moisture and temperature)
confidence 0% · held 0 periods
no soil stream yet: install a moisture and temperature probe
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
