Una National Park is a protected area in the northwestern region of Bosnia and Herzegovina, established to conserve the hydrological, geomorphological and biological values of the Una River basin. The park encompasses riverine landscapes, waterfalls, canyons and karstic plateaus that lie near the border with Croatia and close to the city of Bihać. It plays a central role in regional conservation initiatives involving transboundary cooperation with Plitvice Lakes National Park and other protected areas in the Dinaric Alps.

Geography

The park straddles portions of the Una River valley, incorporating notable features such as the Štrbački buk waterfall, the Martin Brod cascade system, and the canyon segments approaching the confluence with the Sana River. Located within the Una-Sana Canton administrative area and adjacent to the border with Croatia, the park sits on the northeastern edge of the Dinaric karst landscape and integrates limestone plateaus, alluvial plains, and mixed riparian corridors. Elevation ranges from low river terraces near Bihać to karstic ridges that link to broader mountain systems including the Vlašić and Plješivica massifs. The park’s hydrology is influenced by tributaries such as the Klokot and complex underground karst drainage systems that connect to regional aquifers shared with Lika and Kordun regions.

History and Establishment

The area has a long cultural and historical association with medieval and Ottoman-era settlements around the Una basin, including forts and trade routes linked to Bihać Fortress and medieval commerce toward Dubrovnik. During the 20th century the basin was subject to infrastructural projects, wartime impacts during the conflicts of the 1990s involving Bosnia and Herzegovina and neighboring territories, and post-war environmental recovery efforts supported by international organizations such as the United Nations Environment Programme and the World Bank. Conservation advocacy by local NGOs and municipal authorities in Bosanska Krupa and Cazin culminated in legislative action by the entity-level authorities of the Federation of Bosnia and Herzegovina and national ministries, resulting in formal designation in 2008 and subsequent institutionalization through the park directorate modeled on practices from Plitvice Lakes National Park and other IUCN Category II areas.

Flora and Fauna

Una National Park hosts diverse riparian woodlands dominated by species such as European ash stands similar to those cataloged near Neretva Delta sites, and mixed forests containing remnants of Sessile oak and European beech communities akin to those on Velebit slopes. The karstic meadows and wetlands support endemic and regionally significant flora comparable to taxa recorded in the Dinaric Arc and Balkan refugia. Faunal assemblages include aquatic species like the huchen and populations of brown trout that mirror ichthyofauna profiles observed in the Sava and Drina basins, while riparian corridors provide habitat for mammals such as Eurasian beaver, brown bear foragers from adjacent mountain ranges, and carnivores like the golden jackal which has expanded across the Balkans. Avian biodiversity features species tied to riverine and wetland ecosystems, including storks recorded near Bosanski Petrovac and raptors typical of the Dinaric Alps flyways.

Conservation and Management

Management is overseen by the park directorate established under Federation legislation and coordinated with municipal authorities in Bihać, Martin Brod, and Ripač. Conservation planning draws on frameworks promoted by IUCN, the Bern Convention, and transboundary cooperation initiatives with Croatian counterparts in the Plitvice Lakes and Una-Sana cross-border projects. Habitat restoration and water quality monitoring programs have received technical support from bilateral projects with institutions such as the European Union environmental instruments and global conservation NGOs. Zoning regimes within the park delineate strict protection zones, sustainable use areas, and buffer zones that align with EU Natura-like approaches adopted by regional protected area networks. Scientific collaboration with universities in Sarajevo and Zagreb informs species inventories, while law enforcement against illegal logging and poaching is coordinated with cantonal inspectors and law enforcement units.

Tourism and Recreation

Tourism centers on waterfall viewing at Štrbački buk and boat and rafting activities on designated stretches of the Una River, drawing domestic visitors from Sarajevo and international tourists from neighboring Croatia and the EU. Visitor infrastructure includes trails, viewing platforms, visitor centers inspired by practices at Plitvice Lakes National Park, and small-scale eco-lodges in villages like Martin Brod and Ripač. Local tourism enterprises collaborate with regional chambers of commerce such as the Una-Sana Canton Chamber of Commerce and tour operators offering rafting, angling, and guided nature tours that connect to cultural itineraries featuring historical sites like Bihać Fortress and nearby Ottoman-era landmarks. Seasonal festivals and eco-education programs engage stakeholders from municipal councils and NGOs to promote sustainable tourism models.

Threats and Environmental Issues

Key threats include proposed hydropower and water infrastructure projects that mirror controversies seen in the Balkans over river damming, diffuse pollution from urban and agricultural runoff in municipal catchments including Bihać and Cazin, illegal logging pressures noted across the Dinaric Alps, and unsustainable tourism practices. Climate change impacts documented for the Mediterranean-influenced Balkans—such as altered precipitation regimes and increased frequency of extreme drought and flooding—pose risks to river flow regimes and karst aquifers. Conservation responses involve litigation, advocacy by environmental organizations, cross-border policy dialogue with Croatia and EU actors, and adaptive management measures implemented by the park directorate in partnership with scientific institutions in Sarajevo and regional NGOs.
