Responses of functional and taxonomic waterbird diversity to vegetation height and water level variation in a coastal wetland

The dataset describes the variation in abundance of waterbirds across 18 survey sites in a coastal wetland in Western France (Marais Breton). The survey was conducted bimonthly from March 1 to July 31 over 3 to 6 years (2015-2020) depending on the site. Environmental descriptors at the moment of the survey includes water area, variation in water depth and vegetation height. The dataset is related to the following publication Secondi J, Percel G, Arzel C, Davranche A, Farau S (2025) Differing responses of functional and taxonomic waterbird diversity to vegetation height and water level variation in a coastal wetland.
