Reasons for the need for protection/inclusion in annex I

Breeding numbers have declined recently in most European countries, attributed to decrease in habitat quality and availability. Much of the marshes has been lost to drainage, but the abandonnement of traditional management and uses of reed areas has also caused degradation of suitable sites. Local extinctions of the species is probably due to hunting pressure.
