Acrocephalus [genus] (8/5)

The breeding distribution is highly concentrated in a few core areas, notably in northwest Overijssel (150 bp). The species has suffered from eutrophication of water bodies, loss of dynamics in water tables (resulting in insufficient regeneration of wet reed beds) and deteriorated food conditions (lower stocks of larger water insects). Major range contraction and steep declines have resulted in extremely isolated strongholds where the species is becoming increasingly scarce and does not seem to recover at all. The decline is shown by survey data: perhaps 5000 bp in the 1950s, 1200-1600 in 1973-77 and 250-300 in 1998-2000.
