Since the 90s, censuses of wintering waterfowl have been carried out in the main wetlands of Lazio. We analysed the trends of 31 species in the 1993-2006 period (base year 1993) by means of TRIM (Trends and Indices Monitoring data) software (Model 3). Among the species regularly recorded in the region, Ardea alba, Ardea cinerea, Bubulcus ibis and Anser anser showed a strong increase; Podiceps cristatus, Nycticorax nycticorax, Egretta garzetta, Phoenicopterus ruber, Anas penelope, Anas strepera, Anas crecca, Anas platyrhynchos, Anas clypeata, Netta rufina, Aythya ferina, Aythya nyroca, Circus aeruginosus, Fulica atra, Pluvialis apricaria and Vanellus vanellus showed a moderate increase; Gavia arctica, Tachybaptus ruficollis, Podiceps nigricollis, Phalacrocorax carbo, Aythya fuligula and Numenius arquata resulted “stable”; Botaurus stellaris, Tadorna tadorna, Anas acuta, Pluvialis squatarola and Calidris alpina showed an uncertain trend. The trends for most species are similar to those recorded at a national level.
