Status | Conditions on the inbreeding rate (ΔF) | Other conditions |
|---|---|---|
Not at risk | Â | Population status is known or existing knowledge give evidence that the breed does not fall in the other risk categories |
Vulnerable | 0.5 ≤ ΔF < 1 |  |
Endangered-maintained | 1 ≤ ΔF < 3 | The breed is maintained by an active public conservation programme or within a commercial or research facility |
Endangered | 1 ≤ ΔF < 3 |  |
Critical-maintained | ΔF ≥ 3 | The breed is maintained by an active public conservation programme or within a commercial or research facility |
Critical | ΔF ≥ 3 |  |
