The western marsh harrier or the Eurasian marsh harrier is classified as a species of Least Concern on the IUCN Red List. Their large distribution does not let them fall under the group of vulnerable species although they faced near extinction in the 19th century.

However, at present, the breeding pairs are gradually increasing and therefore their status is least concerning.
