4.1 General site character

Habitat class % Cover

Total Habitat Cover


Other Site Characteristics

The area consists of two large carp fishpond complexes with well developed emergent and floating vegetation and wet pedunculate oak forests stretching from Čađavački lug to Koška. It is important breeding area for waterbirds as well as stop-over site during migration. Birds also winter on fishponds as long as they are not frozen during cold weather. Fishponds are important breeding area of Whiskered Tern, Night Heron and Purple Heron and forests of White-tailed Eagle, Black Stork and Middle Spotted Woodpecker. Lithostratigraphic units represented in this area are Pleistocene fluvial deposits and marsh loess and Holocene marsh deposits. Soil: Eutric, Mollic, Calcaric Gleysols-clay soil; Stagnic, Gleyic Podzoluvisols- Surface usually powdery clay whereas the impermeable layer is loam clay.

4.2 Quality and importance

- Information on BD Annex I birds population sizes was provided by the Institute for Ornithology (Zavod za ornitologiju, 2013). Numbers presented refer to estimations or exact data based as much as possible on recent surveys (data provided by the Institute staff and their field-work associates) - Population sizes of non-Annex I regularly occurring migratory waterbirds that represent target features of the SPA area have been estimated only for wintering populations. There is no data available for concentrations – it is to be researched in future. Estimations include numbers from International Waterbird Census for Croatia (2002-2012). The highest counted numbers of each species in the SPA area was taken as Maximum while the Miniumum was estimated, in accordance with Standard Data Form Explanatory Notes. It is hard to evaluate data as all counts were not made on the same day and it is not clear what the coverage of the area was. There should be a survey aimed at registering ‘zero' numbers for each species as the basis for further monitoring of SPA target features - SPA Ribnjaci Grudnjak i Našice holds 16,7% of national breeding population of Ardea purpurea, 6,7% of Nycticorax nycticorax, 5%of Botaurus stellaris, 13% of Egretta alba, 15,6% of Chlidonias hybridus, 5% of Circus eruginosus and 6% of Aythya nyroca - Alluvial oak forests surrounding the fishponds hold 4,4% of national population of Haliaeetus albicilla, 4,4% of Milvus migrans, 4,5% of Ciconia nigra, 4,2% of Ficedula albicollis and 3% of Dendrocopos medius
