South East Forests National Park: A Protected National Park in New South Wales

South East Forests National Park is renowned for its extensive old-growth eucalyptus forests, which represent some of the finest remaining examples of this forest type in southeastern Australia. The park protects critical remnants of temperate rainforest that persist in sheltered valleys and creek lines, creating a mosaic of forest communities. It forms a vital component of a larger trans-frontier wilderness system connecting southeastern New South Wales with eastern Victoria, providing connectivity for wildlife movement across an otherwise fragmented landscape.

The creation of South East Forests National Park followed a protracted conservation battle spanning nearly three decades. Until 1968, much of the inland southeastern corner of New South Wales remained as vacant crown land known as the Wallagaraugh Wilderness, a rugged forested terrain. That year, a scientific committee appointed by the state government recommended protecting approximately 100,000 hectares as a national park. However, the Japanese company Harris-Daishowa sought to log the area for woodchips, and most land was reclassified as state forest, with only Nalbaugh and Nungatta National Parks declared in 1972 and 1973. Logging operations commenced in October 1969 and continued for 25 years despite intensifying opposition. The Unsworth Labor government proposed an 80,000-hectare park as an election promise in 1988 but was not re-elected. Under the Fahey government, five national parks (Genoa, Tantawangalo, Bemboka, Yowaka and Coolangubra) were gazetted in 1994, and these were amalgamated into South East Forests National Park on 1 January 1997.

The park encompasses a varied landscape ranging from steep ridges and broad plateaus to deep gullies and sheltered valleys. The western portions of the park transition into more open terrain characteristic of the Monaro region, while the eastern areas feature the denser vegetation associated with the South Coast. Temperate rainforest occurs in the most sheltered positions, particularly along watercourses and in amphitheatre-like valleys that trap moisture. At higher elevations, the forest gives way to subalpine bogs and heathlands on poorly drained soils. The Black-Allan Line, which marks the border between New South Wales and Victoria, runs along much of the park's western boundary, separating the park from Coopracambra National Park in Victoria.

The park supports an exceptional diversity of forest types, with wet sclerophyll eucalypt forests covering approximately 42 percent of the total area. These forests are characterised by tall eucalypts including several species that achieve their finest development in this region. The temperate rainforest communities represent outliers of the more extensive rainforests found further north along the Great Dividing Range and in southeastern Victoria. These rainforests contain species such as the black olive berry and soft tree fern, which create a distinctive understory. The subalpine bogs at higher elevations support specialised plant communities adapted to waterlogged conditions, adding further ecological complexity to the park. This mosaic of habitats ensures that the park retains high biodiversity values across multiple forest types.

The park provides habitat for a notable array of fauna, including several threatened species. The smoky mouse, a small native rodent listed as threatened, inhabits the old-growth forests and feeds on seeds and fungi. The olive whistler, a bird species vulnerable in New South Wales, is found throughout the park's forested areas. The park forms part of the Ulladulla to Merimbula Important Bird Area, identified by BirdLife International for its significance to the swift parrot, a migratory species that visits the region during the southern winter. The old-growth forest structure, with its abundance of hollows in older trees, provides crucial nesting and shelter resources for arboreal mammals and birds.

South East Forests National Park represents a significant conservation outcome in a region that was extensively logged for more than two decades. The park protects some of the highest quality old-growth forest remaining in southeastern Australia, an ecosystem type that has been vastly reduced by historical clearing and forestry operations. The protection of this forest estate ensures the survival of numerous species that depend on mature forest structure, including hollow-dependent fauna and plants requiring stable microclimates. The park's connectivity with Coopracambra National Park in Victoria creates a transfrontier conservation landscape spanning the Black-Allan Line, facilitating wildlife movement across an area of approximately 100,000 hectares of contiguous protected land from Bombala to Cann River.

The park occupies a landscape that was historically part of the broader Wallagaraugh Wilderness, a remote and rugged area that remained largely unsettled due to its difficult terrain. The land was managed as vacant crown land prior to the mid-twentieth century, with limited traditional use records explicitly documented in available sources. The region's isolation contributed to the survival of forest ecosystems that were cleared or heavily modified in surrounding areas.

The park protects exceptional old-growth eucalypt forests among the finest in southeastern Australia, together with significant temperate rainforest remnants in sheltered valleys and subalpine bogs at higher elevations. It forms part of a contiguous 100,000-hectare wilderness system with Coopracambra National Park in Victoria. The park provides critical habitat for threatened species including the smoky mouse and serves as an important area for migratory birds such as the swift parrot. The landscape offers a transition between Monaro and South Coast regional characteristics, supporting diverse ecological communities within a single protected area.

The park can be visited throughout the year, though the changing seasons bring different characters to the landscape. Autumn and winter months often provide clearer visibility and the opportunity to observe wildlife as animals become more active during cooler periods. The wet eucalypt forests are particularly atmospheric during the cooler months when mist often settles in the valleys. Spring brings wildflower displays in the more open areas and subalpine bogs. Summer offers opportunities for exploring higher elevation trails but visitors should be prepared for variable weather conditions typical of this elevated terrain.
