The construction and restoration of wetlands can improve the living conditions of bird populations. According to a recent study, grazing is the single most important maintenance method for wetlands, due to its diversifying impact. This type of maintenance benefits waders in particular, as well as other birds living in wetlands. The poor condition of wetlands has led to the decline of wetland bird populations around the world. The establishment of a voluntary network of protected areas where hunting is prohibited could facilitate the autumn migration of young wetland birds in particular and balance the hunting pressure they face.
