Project Arenaria was launched in 2009 by the Eco-Ethology Research Unit (ISPA), the National Natural History Museum (MNHN) and the Portuguese Society for the Study of Birds (SPEA) to fill a gap in our knowledge of bird populations using the Portuguese coastline. The 2009/10 field season aimed at assessing the population size and distribution of the waders (and other waterbirds) wintering on the Portuguese mainland coast. This initial survey represents now a baseline for interpreting future population trends of wintering shoredirds in mainland Portugal. Data were also collected in the Madeira and the Azores islands.


Project Arenaria is now moving forward to set an annual monitoring scheme through a sample of squares that were selected taking into account the results of the first field season. This future long-term monitoring will only be possible with the continued collaboration and support of the volunteers.


The 2011/12 field season goals are: 1) to carry on an annual monitoring scheme based on a sample of 63 selected squares in order to obtain data for interpreting future population trends in coastal wintering birds (particularly waders); 2) to obtain further information to complement data on spatial variations in wader abundance and their relationship with habitat features; 3) to raise public awareness for the conservation of coastal and marine ecosystems and their biodiversity.
