Captive Mortality Rate (CMR)
Unplanned monthly mortality across held stock — the bluntest welfare number on the board. A rise sends the team to water quality and disease surveillance before it ever reaches the rewilding pipeline.
Threshold Bands
| Band | Range | State |
|---|---|---|
| Low | < 2% | OK |
| Elevated | 2–6% | WARN |
| Crisis | > 6% | CRIT |
Formula
Logged deaths ÷ mean stock at risk, per month, excluding planned culls.
