Abstract:
A valuable Data base getting along 25 years on 34 bird species from a protected area (Site Ramsar Bistreț, Dolj County, Romania) illustrates permanent presence of 24 water fowl with significant yearly differences between reported taxa. Ecological indexes and species abundance revealed an avian richness in 1998 and the lowest number of species in 2021. These differences could be on the one side because of natural conditions (temperature, relative humidity, drought), and on the other side - because of anthropic pressure, mainly hunting. Therefore the statute of the surveyed protected area should be a real refuge for the protected bird species in a part of the Danube Everglade.
