Justification of Red List category
This species is thought to be undergoing rapid declines based on counts in its North American and European range, owing to the effects of human disturbance, forestry operations around breeding lakes, fluctuating water levels, and the stocking of lakes with Rainbow Trout. It has therefore been uplisted to Vulnerable.
