Status Conditions on the inbreeding rate (ΔF) Other conditions
Not at risk   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
