Area Occupied Justification:
Blue chub are present throughout their range, but amount of available habitat has decreased to 10% of historical levels.
Pop Size Justification:
Not known but assumed to be greatly reduced.
Intervention Dependence Score:
Intervention Dependence Justification:
Populations appear to persistent.
Tolerant but vulnerable to increased water temperatures and low oxygen levels common in summer conditions.
Genetic Risk Justification:
Assumed to be minimal because blue chub are common throughout their range, although populations are in decline.
Climate Change Justification:
Vulnerable to increased temperatures and low oxygen levels, assumed to be exacerbated with increases in water demand.
Information on growth and life history is unknown.
