The Population of European rabbit Oryctolagus cuniculus have declined due to several factors including habitat transformation and viral diseases. At the same time, corrective measures including population restocking in areas with low population densities using rabbits from other geographical areas have been performed. As part of the natural processes monitoring program carried out in the Doñana Biological Station (ESPN-EBD-CSIC), rabbit censuses were conducted in spring and late summer in 2005-2015 at dusk and night along six fixed transects in habitats harbouring rabbits populations. In order to take into account restocked rabbit numbers, annual reports from the doñana Natural Area and data provided by the Lynx team of the LIFE project were incorporated into the study. In All, 52336 rabbits from different parts of western Andalusia were released in the Doñana Biosphere Reserve in 2005-2015. Yet, rabbit populations underwent significant declines, above all in 2013 and 2015, with decreases in some areas up to 80%. These results show intensive rabbit restocking did not increase the native rabbit populations numbers. The impact of the release of rabbits on the population dynamics of the species in Doñana is discussed.
