Gråsæler mangler plads

Der er flere og flere gråsæler ved Christiansø og Gedser, men kun få sæler yngler i områderne. Der er tale om, at betanden er blevet så stor, at gråsælen mangler plads, og derfor rykker sydover.

Seniorforsker Jonas Teilmann ved Nationalt Center for Miljø og Energi på Århus Universitet er ansvarlig for overvågning og optælling af gråsælerne. Han siger til Bornholm.nu at der være tale om, at bestanden i den nordlige Østersø er blevet så stor, at dyrene mangler både plads og føde. Derfor rtkker gråsælen sydover.

For bestanden af gråsæl i hele Østersøen viste en optælling i 2011 knap 24.000 dyr. Kun 1.400 af gråsælerne blev talt i den sydlige del.
