Bare soil increasing — Paddock 7
STM site 4 recorded 38% bare soil at last visit, up from 24% baseline. Bare soil is double-weighted in EHI. Check for overgrazing or prolonged partial rest. Consider moving to adjacent paddock and extending recovery period for P7 by at least 14 days.
↻
Recovery period risk — 3 paddocks moved early
Animals moved out of P3, P5, P9 one day early each. Cumulative effect: 3 days lost from all remaining recovery periods. Current RP now 51 days vs planned 54. If this continues, consider extending current paddock stays to restore RP.
✓
Dung decomposition improving
EOV monitor noted fast dung decomposition at 7 of 10 STM sites — up from 4 at baseline. This indicates improving mineral cycle function. Continue current grazing intervals.

Average grazing period (GP) 4.9 days
Formula used GP = RP ÷ (paddocks − 1)
Recovery period per paddock 54 days
Graze:recovery ratio 1 : 11
Overgrazing risk LOW — adequate recovery
HPG recommendation Slow growth mode: use current RP. Monitor plant growth rates daily.

⚠
Site 4 (P7 area) — bare soil 38% → extend RP 14 days
Bare soil is the primary early-warning indicator. Double-weighted in EHI. Cause: probable overgrazing or partial rest. Control action: do not return herd to P7 until recovery is visually confirmed. Consider herd effect application if partial rest is the cause.
↻
Sites 6–8 — cool season FG declining
Cool season grass vigour score averaged −3 across three sites. This may indicate return to those paddocks is occurring before cool season species have adequately recovered. Review if GP during cool season growth was within plan.
