Banke National Park: National Park of Nepal, Mapped Landscape and Protected Area Geography

Banke National Park is best known as a critical habitat for Bengal tigers within the transboundary tiger conservation landscape of the Bardia-Banke Tiger Conservation Unit. The park protects one of the last remaining extensive tracts of subtropical Siwalik forest ecosystem in Nepal, harboring significant populations of four-horned antelopes and other endangered wildlife. Its position along the Karnali River corridor makes it an important area for biodiversity conservation in the Terai-Siwalik ecological gradient, representing a transition zone between the Himalayan foothills and the Gangetic plain.

Banke National Park was officially established on 12 July 2010, becoming Nepal's tenth national park and the second protected area in the Banke District following the designation of the earlier Banke Wildlife Reserve. The creation of the park fulfilled a long-standing conservation priority to provide formal protection to the Siwalik forests of western Nepal, which had faced increasing pressure from agricultural expansion and resource extraction. The park's designation as a Gift to the Earth reflects the international recognition of its ecological significance, particularly as a component of the larger Bardia-Banke conservation landscape. Prior to national park status, the area had existed as a wildlife reserve, and its elevation to national park status provided enhanced legal protection and administrative resources. The establishment also coincided with Nepal's broader push to expand its network of protected areas and strengthen tiger conservation efforts, as the Bardia-Banke region had been identified as one of the most promising areas for tiger population recovery in the country.

The physical landscape of Banke National Park is defined by its location in the Siwalik Hills, the southernmost mountain range of the Himalayas also known as the Churia Hills. The terrain consists of steep, east-west trending ridges separated by narrow valleys and seasonal watercourses that drain into the Karnali River system. The elevation range within the park spans from the lower foothills to approximately 1,000 meters above sea level, creating a topographic diversity that supports varied habitat types. The underlying geology consists of sedimentary formations including sandstones, siltstones, and conglomerates that have been folded and uplifted, resulting in the characteristic ridge-and-valley topography. The park contains several perennial and seasonal streams that provide critical water sources for wildlife, particularly during the dry season. The landscape transitions from the steeper, forested slopes of the Siwaliks to more gentle terrain at the park's periphery, where agricultural lands and settlements create the boundary with the buffer zone.

The ecological character of Banke National Park reflects the subtropical climate of the Siwalik zone, supporting diverse vegetation communities that include at least 113 tree species, 107 herbal species, and 85 shrub and climber species. Sal forest dominates the lower elevations, forming a dense canopy that provides critical habitat for many wildlife species. The tree species composition includes sal as the dominant species, along with axlewood, Semecarpus anacardium, khair, and Terminalia alata as common associates. The forest structure varies from pure sal stands in some areas to mixed deciduous forests on slopes receiving more sunlight. The park's position along the Karnali River system creates ecological connectivity that facilitates wildlife movement between the Siwalik hills and the Terai floodplains, supporting the large mammal communities that require extensive home ranges. The diverse vegetation supports a corresponding diversity of invertebrate and vertebrate species, making the park a biodiversity hotspot within the Terai Arc Landscape.

Banke National Park supports significant populations of large mammals, with the Bengal tiger being the flagship species and primary conservation focus. The park forms part of the Bardia-Banke Tiger Conservation Unit, which represents one of the most important tiger habitats in Nepal and potentially one of the last areas in the country capable of supporting viable tiger populations. The four-horned antelope, a species of conservation concern, is among the notable ungulate species found within the park. Small mammal diversity includes the ruddy mongoose, which was first recorded in the park in 2014, expanding the known range of this species. The diverse forest habitats support numerous bird species and smaller mammals that form the prey base for larger carnivores. The park's connectivity to Bardia National Park allows for wildlife movement across a larger landscape, supporting genetic exchange between populations and enhancing long-term conservation viability.

Banke National Park plays a crucial role in Nepal's conservation strategy, particularly regarding tiger recovery and Siwalik ecosystem protection. The park's inclusion in the Bardia-Banke Tiger Conservation Unit represents a landscape-level approach to conservation that recognizes the space requirements of large carnivores and the importance of connectivity between protected areas. The 1,518 square kilometer coherent protected area formed by Banke and Bardia represents one of the largest contiguous conservation landscapes in Nepal and serves as a model for integrated conservation planning. The surrounding buffer zone of 344 square kilometers reflects a collaborative approach that involves local communities in conservation through sustainable resource use and anti-poaching efforts. The park's designation as a Gift to the Earth acknowledges its global significance as a representative sample of Siwalik biodiversity and its contribution to international conservation targets for species like the Bengal tiger.

Banke National Park is located in a region of Nepal with rich cultural heritage, situated within Lumbini Province near the birthplace area of the Buddha. The local communities in the surrounding Banke, Salyan, and Dang Deukhuri Districts have historical connections to the landscape, with traditional land use practices that have shaped the region's character. The buffer zone approach recognizes these community relationships and seeks to balance conservation objectives with the livelihoods of people who have inhabited the area for generations. While the park itself focuses on wildlife protection, the broader region includes important cultural sites and the buffer zone management involves local stakeholders in conservation planning.

The Banke-Bardia conservation landscape represents one of Nepal's last great wilderness areas, protecting extensive Siwalik forest ecosystems and supporting viable populations of Bengal tigers. The park's position in the Siwalik Hills creates distinctive terrain with forested ridges and valleys that offer a different character from the more famous Terai parks of central Nepal. The diversity of vegetation, with over 100 tree species, supports a corresponding richness of wildlife and creates a vibrant forest environment. The relatively recent establishment of the park in 2010 means it remains one of Nepal's less-visited national parks, offering a wilder and more remote experience compared to more established destinations.

The optimal time to visit Banke National Park coincides with the dry season from October through May, when wildlife viewing opportunities are best as animals concentrate around remaining water sources. The period from November to February offers comfortable temperatures and clear skies, making it the most popular time for visitors. The pre-monsoon months of March through May can be particularly good for wildlife viewing as the landscape dries, though temperatures may rise significantly. The monsoon season from June to September brings heavy rainfall to the Siwalik region, making some areas difficult to access and reducing visibility for wildlife observation.
