Abstract

The Mediterranean Waterbirds Network (MWN/ROEM) supports and coordinates waterbird counts across the Mediterranean basin. Created in 2012 as part of the AEWA African Initiative, it was initially developed with five North African countries (Morocco, Algeria, Tunisia, Libya, and Egypt), in partnership with Tour du Valat and the French Biodiversity Agency (OFB), to improve the quantity and quality of these surveys.

Since 2017, the Mediterranean Waterbirds Network (MWN/ROEM) has expanded to include other Mediterranean countries, fostering scientific and technical exchanges and collaborations. Among these countries, the most significant partnerships are with Albania, Spain, France, Italy, Greece, Serbia, North Macedonia, Montenegro, Portugal, and Turkey.

This year, thirteen of these countries have renewed their collaboration to prepare national technical reports, as well as a general overview of the status of waterbird counts (DIOE).
