Sažetak
The breeding population of spoonbill in Croatia, estimated at 154-275 breeding pairs, is classified as endangered. The main reason for the unfavourable status is loss of breeding/feeding habitats. The purpose of the study was to detect changes in the habitat types previously assessed as important for spoonbills feeding. The area of interest is the central part of the Sava River. The research area was chosen for two reasons: 1) the alluvial wetland of the Sava River holds the biggest colony of spoonbills in the Croatia and 2) availability of data on feeding ecology of spoonbills along alluvial wetlands of Sava River. We used the MODIS (Moderate Resolution Imaging Spectroradiometer) Enhanced Vegetation Index (EVI) as the main indicator for the changes in the habitat structure along critical habitats for spoonbills. The results of the analysis identified areas with significant changes in EVI index for habitat types important for feeding of the spoonbills. Pastures, especially those with high wetness potential changed in significant percentage despite conservation efforts on this habitat type.
