Seal Count 2012: more seals than ever before in the Wadden Sea
The total count of 26,220 Harbour seals in the Wadden Sea was composed of 3,966 (570 pups) in Denmark, 9,268 (3,247) in Schleswig-Holstein, 6,457 (1,977) in Lower Saxony and Hamburg, and 6,529 (1,473) in the Netherlands. This is an increase of almost 11% compared to 2011. The number of pups born in 2012 has also grown, but less significantly. During the peak in pupping in June, 7,267 pups were counted, which is 3% more than last year. “We are again excited about this year’s continued growth, a sign that our common efforts to protect the seals and their habitats are effective”, - says Jens Enemark, head of the Common Wadden Sea Secretariat in Wilhelmshaven, which is responsible for the seal monitoring coordination. – “Since the inscription of the Dutch-German Wadden Sea into UNESCO World Heritage list in 2009, we have an obligation toward the world community to take great care of this unique nature area”.
The general increase is however unevenly distributed. It spans from 10% growth in Schleswig-Holstein to 37% in Lower Saxony and Hamburg, whereas the seal number in the Netherlands decreased by 12%. This clearly demonstrates the value of coordinated counts that provide a single most accurate estimate of the entire Wadden Sea seal population within a few days in August. Since seals are very mobile, migration within the Wadden Sea and into adjacent waters is seen as a potential reason for observed differences.
