Bioregional Integrity Score
BIS is improving but below sustainability threshold. Acacia restoration in northern plots is a positive signal. Priority actions: increase water retention capacity before dry season peak, reduce erosion exposure on exposed ridges. Rotational grazing implementation is on plan — maintain current rotation schedule for maximum soil recovery. Locust risk warrants community-level preparedness coordination with FAO regional office.

Erosion rill formation — Zone 3 southeast slope
Satellite imagery delta (L8 Landsat) shows 340m of new rill formation along eastern slope of Zone 3 following 38mm rainfall event. PCI model estimates 2.1 BIS point degradation if unaddressed within 30 days. Recommended action: contour bunding or check-dam installation on 3 identified gullies. Estimated cost: 180,000 CFA (~$280). Your confirmation triggers work order to village conservation committee.
Herd movement — potential overgrazing boundary breach
Cattle GPS collars detect 280-head herd entering Zone 2 recovery block 12 days before scheduled rotation date. Pasture biomass estimate: 40% below recovery threshold for safe grazing. If herd remains 48h+, estimated pasture setback of 3-4 weeks recovery time. Zone 2 BIS subscore projected to drop 1.4 pts.
Anomalous vegetation greenness spike — possibly invasive
MODIS NDVI detected unusual greenness cluster (0.62 vs 0.38 seasonal baseline) in a 4ha patch at Zone 7 riverine margin. Pattern is inconsistent with native Acacia or Balanites species signatures. Could indicate invasive Prosopis juliflora expansion. Field confirmation needed — Prosopis would require urgent removal programme.
