- Description: A cross-border remote-sensing workflow validated against 590 peatlands found that disturbed sites were disproportionately hard to detect, turning classification error itself into a restoration signal.

Alpine peatlands and cross-border remote sensing

## WHAT THE EVIDENCE SAYS

A Communications Earth & Environment study developed a harmonized multi-sensor workflow for mapping peatlands across the European Alps using 590 ground-reference peatlands, Sentinel-2 optical data, Sentinel-1 radar, Landsat surface temperature and terrain information. The best-performing model was dominated by Sentinel-2 features. Importantly, official mapped peatlands were more likely to be missed where orthophotos showed forest encroachment or agricultural disturbance, while some apparent model false positives may represent unmapped peatlands.

## WHY IT MATTERS / OUR READ

Monitoring error is not always random. If degraded peatlands become less visually or spectrally peatland-like, the systems most in need of restoration can disappear from inventories built around intact reference conditions. That makes disagreement between maps and models a useful trigger for targeted field verification rather than just a classification nuisance.

## CAVEATS / UNCERTAINTY

Remote sensing cannot by itself diagnose peat depth, hydrologic condition or restoration priority. Official inventories also vary among countries, so some disagreement reflects reference-data limitations as well as ecological degradation. Candidate unmapped peatlands still require field confirmation.
