On 28-30 April 2010, over 20 researchers and administrators met in Vladivostok, in the Russian Far East, to develop an action plan for the Scaly-sided Merganser Mergus squamatus – a globally threatened diving duck. The workshop was coordinated by the Russian hosts and involved participants from the species’ main range states (Russian Federation, People’s Republic of China, Democratic People’s Republic of Korea, and Republic of Korea) and other experts and supporters. The EAAF Partnership was represented by the Chief Executive and the Science Officer. Analysis of threats revealed encouraging prospects for addressing major threats (hunting, drowning in nets) on the breeding grounds; threats on the main wintering grounds (pollution, dams) are, however, operating at landscape scales and may be more challenging to reduce. Following compilation and a review process, the draft action plan will be presented by the project leader (Wildfowl & Wetlands Trust, on behalf of the planning team) to the Fifth Meeting of EAAFP Partners, for formal endorsement.
