BiologicalAll MPGs within an ESU must be at
low risk (viable)1) ½ or at least 2 populations within MPG
viable or highly viable.
2) At least one population highly viable.
3) Proportional representation of very large, large, intermediate populations
4) All major life histories represented
5) Populations not meeting viability standards should be maintained
