Rezerwat przyrody „Sugry” imienia Janusza Szostakiewicza: A Protected Lowland Forest Reserve

Sugry is best known for protecting a rare inland dry pine forest of the Cladonio-Pinetum type, valued primarily for its extraordinarily rich lichen flora rather than for its trees alone. Surveys have recorded around 69 lichen species in the reserve, including several strictly protected and many red-listed taxa, making the site a notable reference for lowland lichen conservation in Poland. The reserve is also recognized as a place where natural forest succession on formerly cultivated land has produced a habitat of high scientific and conservation value, situated within one of Poland's most important transboundary riverine protected-area networks.

The idea of formally protecting the Sugry area dates back to the 1990s, but the practical groundwork for the reserve only came together in the early 2020s. Between 2014 and 2016, researchers from the University of Life Sciences in Lublin, including the lichenologist Danuta Urban, carried out detailed field studies that documented the exceptional lichen diversity of the site and identified it as a candidate for formal protection. Their findings helped justify the establishment of a reserve dedicated specifically to preserving a rare lowland dry pine forest community.

The reserve was officially established on 9 September 2021 by order of the Regional Director for Environmental Protection in Lublin, which defined both the core area of around 44 hectares and a surrounding buffer zone of approximately 31 hectares, formalizing the protection that had been a local and scientific aspiration for many years. The administrative act came amid a broader period in which Polish regional environmental authorities were expanding the network of small protected sites along the Bug valley.

The name of the reserve carries a double dedication. It refers to the historic locality of Sugry itself, which is connected to the former village of Suhre, also written as Suchry, a small settlement that emerged in the early nineteenth century and no longer exists on modern maps. The reserve also honors Janusz Szostakiewicz, a nature conservator active in the former Biała Podlaska Voivodeship and later at the Regional Directorate for Environmental Protection in Lublin, who lived from 1951 to 2011. Szostakiewicz is remembered as one of the initiators of the West Polesie International Biosphere Reserve and of the Podlaski Przełom Bugu Landscape Park, of which Sugry's protected landscape area is a natural extension.

The Sugry reserve lies on sandy, post-glacial terrain typical of the eastern Lublin region, on the edge of two clearly contrasted physical-geographical units. The core of the area sits within the Parczewsko-Kodeńska High Plain, an undulating outwash landscape shaped by Pleistocene processes, while very nearby the land drops toward the wide alluvial valley of the middle Bug River. The boundary between upland and river floodplain is just a short distance from the protected site, giving the reserve a setting that combines dry sandy uplands with proximity to a large lowland river system.

Within the protected perimeter, the terrain is relatively flat to gently undulating, with sandy soils that were once used for agriculture. After cultivation stopped in the mid twentieth century, the land reverted to forest in a process of ecological succession visible across the area. Today the surface is dominated by single-species stands of Scots pine mixed with silver birch, with a sparse shrub layer and a ground cover shaped by light intensity, dryness, and the slow accumulation of natural litter.

The wider landscape around the reserve is shaped by the presence of the Bug River itself, which runs just beyond the western edge of the protected area and forms the Polish-Belarusian border. The river's floodplain introduces a contrasting moist, open environment next to the dry woodland of the reserve, creating a sharp ecological gradient between continental pine forest and riverine wetland habitats within a small geographic radius.

Ecologically, Sugry is a textbook example of how ecological succession on abandoned farmland can produce valuable habitat when allowed to run its course. The site's defining feature is its inland dry pine forest community of the Cladonio-Pinetum type, characterized by Scots pine dominance and a ground layer built around fruticose lichens rather than typical mesophilic forest herbs. This kind of habitat represents a relict landscape type that has retreated dramatically across Central European lowlands.

The reserve's biodiversity signal comes especially from its lichen communities. Surveys have identified approximately 69 lichen species across the site, including a notable share of legally protected taxa. Five species enjoy strict protection in Poland, among them species such as Bryoria motyki, Hypogymnia physodes relatives, Ramalina fraxinea, Usnea comosa, and the pine-associated Vulpicida pinastri. A further 13 species are partially protected, and 17 species appear on Poland's red list of threatened and endangered lichens and fungi.

In addition to lichens, the reserve hosts a documented bryophyte flora of around 19 moss and liverwort species, some of which are also under partial legal protection. While the vascular plant flora is unremarkable in species number, the combination of pines, sandy substrate, open canopy, and undisturbed continuity has allowed a cryptogam community of unusually high regional importance to develop.

Sugry is fundamentally a botanical and lichenological reserve rather than a large-mammal sanctuary, and its wildlife value is concentrated in lesser-seen groups of organisms. Its most celebrated fauna is effectively the lichen communities themselves, treated in Polish nature conservation as an ecological asset of high priority because of their sensitivity to air quality, habitat continuity, and microclimate.

The reserve also plays an indirect but meaningful role for fauna through its position inside the Dolina Środkowego Bugu Special Protection Area for birds. The middle Bug valley is one of eastern Poland's most important corridors for wetland and riverine bird species, and although Sugry itself is dry woodland, its inclusion in this larger protection zone means that species using both the floodplain and upland edges may benefit from the protected mosaic. As of early 2022, the reserve did not yet have a formal protection plan or defined conservation tasks, reflecting its relatively recent establishment and the ongoing process of integrating it into managing authority workflows.

From a conservation perspective, Sugry's importance rests on three reinforcing pillars: habitat rarity, lichen diversity, and transboundary connectivity. Dry, continental Scots-pine forests of the Cladonio-Pinetum type have become vanishingly rare across the Polish lowlands because of land-use change, commercial forestry, and disruptions to ecological succession, and every substantial surviving example has high regional significance. Sugry's nearly 70 recorded lichen species, including critically protected and red-listed taxa, put it on the short list of Polish forest reserves that meaningfully conserve cryptogam biodiversity at a regional scale.

The reserve also derives much of its protective value from being embedded in a layered network of overlapping nature conservation designations. It falls within the European Natura 2000 framework through the Dolina Środkowego Bugu Special Protection Area for birds, a site of shared Polish-Belarusian relevance along the river. It is additionally covered by the country's Nadbużański Protected Landscape Area, providing buffer-level landscape protection, and sits within the transboundary West Polesie Biosphere Reserve, an internationally designated biosphere area connecting Polish and Belarusian protected territories. Sugry's 44-hectare core, together with its roughly 31-hectare buffer zone, acts as a small but well-placed node inside this broader system.

At the administrative level, the reserve was created in 2021 by the Regional Director for Environmental Protection in Lublin, and early in 2022 it remained without a formally adopted conservation plan or defined conservation tasks, an indicator that its long-term active management framework was still under development at the time of its establishment.

Sugry carries a layered cultural identity that combines a memorial dimension, a local geographic name, and the broader regional heritage of the Bug borderline. The name of the reserve is rooted in the historic locality of Sugry, itself connected to the once-existing village of Suhre or Suchry, a small early nineteenth-century settlement that does not survive in current settlement patterns of the area.

The reserve's dedication to Janusz Szostakiewicz gives it a second, explicitly biographical layer of meaning. As a long-serving regional nature conservator in the old Biała Podlaska Voivodeship and later a staff member of the Regional Directorate for Environmental Protection in Lublin, Szostakiewicz is remembered locally as one of the architects of some of the most important modern protected areas along the Bug, including the West Polesie Biosphere Reserve and the Podlaski Przełom Bugu Landscape Park. Naming the reserve after him is both a regional tribute and a symbolic connection to the wider borderland environmental protection tradition.

The position of the reserve directly adjacent to the Bug River and the Polish-Belarusian border also situates it within the cultural geography of the eastern Polish borderland, a region historically shaped by multilingual rural communities, shifting borders, and the slow emptying of villages in the postwar period. The forest that now constitutes the reserve grew up largely on land abandoned by those communities, making the protected site at the same time a product of, and a quiet monument to, the recent rural history of the region.

Sugry's defining highlights are compact but unusually distinctive for a small reserve. It protects a rare inland dry pine forest of the Cladonio-Pinetum type, a habitat that anchors the reserve's legal purpose and scientific profile. The lichen flora of nearly 70 documented species, including strictly protected taxa and red-listed species, is the single most compelling feature of the site from a conservation perspective.

The reserve's geographic position is another highlight in its own right. Tucked between the Parczewsko-Kodeńska High Plain and the middle Bug valley, just steps from the Polish-Belarusian border, Sugry acts as a small national unit inside a remarkably layered international network: a Natura 2000 bird protection area, a Polish protected landscape area, and a transboundary biosphere reserve. Its dedication to Janusz Szostakiewicz and to the lost village of Suhre gives the place an additional human-historical layer that connects local memory to broader regional environmental history.

Sugry is a scientific and conservation reserve rather than a visitor attraction, and access is determined primarily by its protected status and by natural cycles of lichen visibility, bird activity, and forest microclimate. For visitors interested in understanding the site, the warm half of the year, roughly late spring through early autumn, is generally the most rewarding window. This period brings more comfortable ground conditions for walking within or near the protected perimeter, easier insect and bird observation in the broader Bug valley mosaic, and better visibility for ground lichens when humidity is moderate and ground vegetation is not snow-covered.

Late winter and early spring can highlight a different character of the site, with bare deciduous birches, low sun angles that emphasize the openness of the pine canopy, and visibility into the surrounding high-plain landscape, but the same conditions also bring wetter, sometimes frozen ground and longer periods when bird observation along the nearby Bug floodplain is less favorable. Because the reserve does not yet have a formal management plan, visits are best understood as low-key, scenery- and ecology-oriented trips rather than as operations with structured visitor services.
