Justification of Red List category
The population is restricted to a small core breeding area within Europe, with 99% population found at sites in Poland, Belarus and Ukraine. A significant proportion of the breeding habitat could be rapidly affected by droughts, fires, or floods, and the species is assessed as having fewer than 10 locations for these threats. A population decline is ongoing due to habitat degradation, even in areas subject to extensive conservation efforts; outside the core range, rapid declines continue and further national extinctions are also likely. The small breeding range, few locations and continuing decline mean that Aquatic Warbler is assessed as Vulnerable.
