<abstract xmlns="http://www.w3.org/1999/xhtml"><p>Due to numerous bird surveys in the past 20 years, the avifauna of Goričko is relatively well known.

Most of the qualifying species of this habitat that are protected within the Natura 2000 network have suffered a decline at Goričko, specifically Quail <italic>Coturnix coturnix</italic>, Scops Owl <italic>Otus scops</italic>, Hoopoe <italic>Upupa epops</italic>, Woodlark <italic>Lullula arborea</italic> and White Stork <italic>Ciconia ciconia</italic>. The number of breeding pairs of the latter has not changed, but its fecundity has decreased.

National agricultural and nature conservation policies are evidently inefficient in protecting the biodiversity of Goričko. The most probable cause for bird population decline is agricultural intensification, which manifests itself at Goričko as disappearance and intensification of meadows, land consolidation, degradation of traditional orchards and use of pesticides. As a result of land consolidation hedges, uncultivated strips between fields, individual trees and bushes and minority habitat types are disappearing, whereas the surface of arable fields is increasing. Nature conservation measures performed by the Public Institute Goričko Nature Park with the support of DOPPS – BirdLife Slovenia volunteers seem to be efficient, but are spatially and temporally constrained. For this reason, they cannot serve as a substitute for insufficient systemic financing which could be improved by substantive and financial reform of the agri-environmental scheme. Currently, a negligible percentage (1% in 2016) of Goričko is covered by agrienvironmental scheme measures with positive influence on qualifying species and habitat types. As a consequence, only an insignificant share of subsidies from the Rural Development Plan is used for nature protection at Goričko. If the system of agricultural subsidies remains unaltered, no improvement of the conditions for bird conservation at Goričko can be expected.</p></abstract>
