White stork (Ciconia ciconia L.) as an indicator of natural environment status in agricultural areas, illustrated with an example of Masurian Landscape Park

Abstract

The paper presents the results of a 5-year study on the population size of the white stork (Ciconia ciconia L.) as one of the indicator species used to assess a biodiversity level in agricultural areas. The study was carried out in Masurian Landscape Park situated in Warmińsko-Mazurskie Voivodeship. The results demonstrated that the white stork population size was closely linked to agricultural areas, in particular, the extensively managed permanent grassland. In the years 2014–2018, even if minor changes were observed in the land use structure, the white stork population size showed a slight upward trend within the study area. In order to maintain this status, efforts should be made to preserve open landscapes (first and foremost – meadows and pastures), which are preferred feeding grounds of white stork. Consequently, potential decision as regards afforestation and housing should be made considerately.

Composition and Distribution on a Host of Avian Lice of White Storks in North-Eastern Algeria

“…The white stork Ciconia ciconia (Linnaeus, 1758) is one of the most important indicators of environmental conditions, providing useful information on the biodiversity of agricultural rural areas [22]. The white stork is also a migratory bird with a breeding range that spans Europe, North Africa, and the Middle East [23].…”
