Pastures of the Great Bustard

Pastures of the Great Bustard (Pašnjaci Velike Droplje) is a Special Nature Reserve in Vojvodina's North Banat District, specifically designated to protect one of the last remaining habitats of the great bustard in Serbia.^[1] The reserve encompasses approximately 6,779 hectares of open steppe grasslands and agricultural mosaics across three separated units—Jaroš, Kočovat, and Siget—that together provide the extensive, undisturbed landscape required by this spectacular bird, the heaviest flying species in the world.^[2] This reserve represents Serbia's primary commitment to great bustard conservation, protecting the country's only remaining population at the species' southeastern European range limit.

The reserve's primary conservation target is the great bustard, Serbia's last remaining population, estimated at only 15–20 individuals with approximately 10 reproductive females.^[3] Great bustards are the heaviest flying birds in the world, with males weighing up to 18 kg, and their elaborate courtship displays are among the most spectacular in the avian world.^[2] Other steppe bird species include stone curlew, Montagu's and hen harriers, short-eared owls, and various lark species, while the grasslands support populations of European ground squirrels, hares, and partridges.

The vegetation consists primarily of natural and semi-natural grasslands dominated by fescues and other steppe grasses that create the low, open structure required by ground-nesting bustards and other steppe birds.^[4] The flora includes typical Pannonian steppe species alongside halophytic elements in areas with higher soil salinity, creating a diverse grassland mosaic across the relatively flat landscape. Management maintains the grassland character through controlled grazing and mowing regimes that prevent scrub encroachment while preserving the diverse herbaceous community and the structural heterogeneity important for invertebrate prey populations.

The reserve occupies flat terrain on deep loess and alluvial deposits typical of the North Banat District, with fine-textured soils that create the grassland conditions favoured by great bustards.^[4] The underlying geology consists of Quaternary aeolian and lacustrine sediments of the Pannonian Basin, creating generally fertile soils that were largely converted to agriculture during the 18th and 19th century colonization of the region. The subtle topographic variations within the flat landscape create local differences in soil moisture and chemistry that support the mosaic of grassland types found within the reserve.

The North Banat experiences one of Serbia's most continental climates with hot, dry summers, cold winters, and relatively low annual precipitation around 550 mm. The open, flat landscape is exposed to strong winds, particularly the cold Košava blowing from the southeast in winter, creating harsh conditions that the hardy great bustards have adapted to over millennia. The climate's seasonal extremes drive the bustard's annual cycle, with males displaying on traditional lekking grounds in spring and the birds forming larger winter flocks that utilize the best available foraging areas across the landscape.

The great bustard was once abundant across the Pannonian steppe, with historical records describing flocks of hundreds of birds in the grasslands that covered much of the Banat before agricultural conversion. The progressive loss of steppe habitat during the 18th and 19th century Habsburg colonization reduced bustard populations dramatically, from potentially thousands of birds to the remnant population that survives today. Traditional low-intensity farming practices of the military frontier settlements were initially compatible with bustard survival, but agricultural intensification in the 20th century eliminated most remaining suitable habitat.

The reserve was established in 1997 specifically to protect the great bustard and its habitat, responding to the species' catastrophic decline across its former Serbian range during the 20th century.^[5] The reserve was subsequently expanded from its original 979 hectares to over 6,700 hectares, incorporating additional steppe and agricultural land across three separated units.^[4] Management is designed around the species' ecological requirements, maintaining large undisturbed grassland blocks during the breeding season and ensuring year-round habitat availability within an intensively farmed landscape.

The reserve's primary attraction is the opportunity to observe great bustards in their natural habitat, with the males' spectacular courtship display in spring being one of the most dramatic wildlife spectacles in Serbia. Observation must be conducted from considerable distance using telescopes to avoid disturbing these extremely wary birds, and the reserve's flat, open character actually makes long-range observation practical. The steppe landscape itself, with its vast horizons and subtle grassland beauty, offers a unique experience of a vanishing European landscape type.

The reserve is located in the North Banat District of Vojvodina near the village of Mokrin, accessible from Kikinda and nearby towns by local roads. Due to the extreme sensitivity of great bustards to disturbance, visitor access is carefully managed with designated observation points at appropriate distances from known bustard areas. Visits should be coordinated with reserve management, particularly during the spring breeding season when disturbance could cause nest abandonment. Binoculars or a telescope are essential for meaningful observation of the birds.

Conservation management is entirely focused on maintaining and improving conditions for the great bustard, including prevention of disturbance during breeding season, maintenance of grassland habitat through appropriate management, and reduction of threats from agricultural operations.^[3] Power line collisions represent a significant mortality factor, and mitigation measures including marking of lines and burial of cables have been implemented in key bustard areas. The long-term viability of this small population depends on habitat connectivity with larger Hungarian populations across the border, making cross-border conservation cooperation essential for species survival.
