Justification of Red List category
Conservation measures have resulted in a population increase in Europe, particularly at the species's largest colony, at Lake Mikri Prespa in Greece, and also in other countries, following implementation of conservation actions. However, rapid population declines in the remainder of its range are suspected to be continuing and therefore the species is listed as Vulnerable.
