Introduction Agreement Text Summary Sheet Secretariat

Introduction

The Agreement was concluded in response to a dramatic decline in the Common seal population in the Wadden Sea in 1988, which was caused by an infection of the phocine distemper virus. Since then, the population has recovered significantly. In 2002 however, the same virus caused the death of a substantial portion of the common sea seal population in the Kattegat/Skagerrak area, the Wadden Sea and the North Sea.

Events like the outbreak of the phocine distemper virus are natural in wild populations and cannot be prevented or cured. However, the environmental conditions of seals are still not satisfactory. The present and short-term conservation status of the seals in the area is primarily determined by pollution and disturbance as results of various human activities. The mitigation of threats created by disturbance (for example tourism activities) and habitat destruction (through dredging, the construction of dikes and dams) can however only be achieved through international cooperation.

The Agreement

The trilateral Agreement was concluded between Denmark, Germany and the Netherlands on 16 October 1990 in Bonn, Germany, and entered into force one year later. The Secretariat is located in Wilhelmshaven, Germany.

The geographical range of the Wadden Sea Plan is the Trilateral Wadden Sea Cooperation Area (or Wadden Sea Area), which is an offshore zone three nautical miles from the baseline as fixed nationally including all islands.

The aim of the Agreement is to promote close cooperation amongst the Parties in order to achieve and maintain a favourable conservation status for the Common seal population, which is an irreplaceable component of the Wadden Sea and an important indicator of its environmental health.

The Seal Management Plan (2002 – 2006)

The Seal Management Plan (2002-2006) builds on the obligations of the Seal Agreement and contains objectives and action points on habitat protection, research and monitoring, pollution and wardening, taking and public information.

The plan covers the Wadden Sea stock of the Common seal (Phoca vitulina vitulina) and is also extended to cover the two breeding stocks of the Grey seal (Helichoerus grypus) in the Wadden Sea, the latter one not covered by the Wadden Sea Seal Agreement. The overall aim is restore and maintain viable stocks and a natural reproduction capacity, including juvenile surviving of the Common and Grey seal.

It is an essential instrument that seeks a balance between conservation and management of the area, and contributes to achieving viable stocks. The Parties continuously amend the plan in order to meet the challenge of protecting this flagship species of the Wadden Sea.
