IntroductionThe research was conducted at the location of Švajcerova ada in Darda municipality. The site is part of the Mura – Drava Regional Park.
An area of dense reeds according to the National Habitat Classification of Croatia is habitat type Phragmito-Magnicaricetea. These are
the remains of the wetland and stand water body which are in a late stage of succession. Under the influence of the river meandering,
the meander gradually separates from the main watercourse and a stand water body or lake is formed. With the formation of standing
water body, the process of succession is accelerated. With the increase of organic material over time, the water level declines and the
amount of sludge and vegetation increases. process of changing habitat types from aquatic over wetland to terrestrial and forest is
ongoing.
Materials and methodsThe monitoring method was carried out
according to the Protocol for bird (Aves)
monitoring in floodplains of the
continental part of Croatia. Special
emphasis is on bird species that are
related to the specified habitat type;
Acrocephalus melanopogon, Circus
aeruginosus, Luscinia svecica and Panurus
biarmicus. The goals of the research are
the analysis of the condition of the entire
bird fauna at study site.
ResultsA total of 42 bird species were determined and 254 individuals (Table 1.). However, after abundance analysis, it can be concluded that
at least 136 individuals were recorded during the monitoring. Of the targeted species, the presence of was Circus aeruginosus
determined. Of the total number of species, 42 are nesting (100,00%), 19 are resident birds (45,24%), 19 are migratory (45,24%) and 7
are wintering (16,67%) (Graph 1.). According to the Red Data Book of Birds of Croatia, species are classified into 4 categories.
Endangered species in this case are those belonging to categories EN and VU. Of the total number of determined species, 36 species
belong to LC (86%), then 1 to NT (2.4%), while there are two species in categories VU i EN (4.8%). In category VU are Anser anser and
Ciconia nigra, while in the EN category are Casmerodius albus and Circus aeruginosus (Graph 2.). During the research, a total of 26
strictly protected species were recorded, which makes 61,90% of the total number of determined species. 4 species (9,52%) are
considered endangered (Graph 3.). The results show the great importance of preserving marshland habitats as suitable for bird fauna,
especially for endangered and strictly protected species, many of which are related to this habitat type.
