Deskripsi
Deliblato sands is an isolated foreststeppe area of about 350 km2 within the agricultural area of the South East Pannonian Plain. In this area, 200 years ago, people began to foresting sand dunes in order to ban sheep grazing in the second half of the last century and continue to afforest open grasslands with steppe-pasture biocenoses. This jeopardized many sparsed species of mammals and birds, in particular Eastern Imperial Eagle (EIE) (Aquila heliaca). In the period brtween 1963–1967 in the central parts of the Deliblato sands, 5 nests of the EIE pairs were distributed (localities: V. Kravan, Ćarlika, Orlovo gnezdo, Crni Vrh and Plop). A detailed monitoring of the entire bird fauna, especially the EIE in the reproductive period, started in 1976 and ended in 1986. Given that complete data on this monitoring have not been published until today, for more than 20 years we do not have scientifically verified data on nesting of this species, also Deliblato sands continues to be a potential breeding area for the EIE, I have decided to present the old data, in order to point out the necessity of organizing and conducting a comprehensive and long-term search and monitoring, which has not been done until today.
