Tarra-Bulga

Tarra-Bulga National Park encompasses approximately 1,512 hectares of exceptional cool temperate rainforest and tall wet sclerophyll forest in the Strzelecki Ranges of South Gippsland, approximately 250 kilometres southeast of Melbourne. The park protects some of the best remaining examples of Strzelecki Range cool temperate rainforest, with magnificent stands of myrtle beech, towering mountain ash, and a lush understorey of tree ferns, mosses, and liverworts. Tarra-Bulga is one of the most accessible cool temperate rainforest destinations in Victoria, with well-developed walking tracks providing access to the atmospheric rainforest environments for day visitors from the Latrobe Valley and Melbourne.

Tarra-Bulga National Park supports diverse wildlife in its rainforest and tall forest environments. Superb lyrebirds are abundant and are among the most readily observed and heard in Victoria, performing their extraordinary songs throughout the forest year-round. Common wombats graze in more open areas. Common brushtail possums and mountain brushtail possums inhabit the forest canopy. Greater gliders use the tall eucalypt forest. Platypus have been recorded in the Tarra River. Powerful owls hunt the park's forests. The endangered spot-tailed quoll has been recorded. Flame robins, pilot birds, and various wrens inhabit the forest understorey. The park is also home to a variety of frog species in its moist environments.

The cool temperate rainforest of Tarra-Bulga National Park is among the finest remaining examples in the Strzelecki Ranges, a region that has lost most of its original forest cover to dairying and agriculture. Myrtle beech forms the dominant canopy of the rainforest, with its smooth grey bark creating a distinctive appearance in the mature forest. Beneath the beech canopy, soft tree ferns and rough tree ferns create spectacular displays of fronds. Mosses and liverworts coat every surface in the moist gully environments. Mountain ash and messmate form the tall wet sclerophyll forest on the drier slopes above the rainforest. The park contains several rare and threatened plant species.

Tarra-Bulga National Park is underlain by Devonian granite and Silurian sedimentary and metamorphic rocks of the Strzelecki Ranges. The moist, sheltered gully environments created by the incision of the Tarra River and its tributaries into the granitic terrain provide the conditions necessary for cool temperate rainforest. The deep, organic-rich soils of the gullies are maintained by the decomposition of abundant leaf litter and fallen logs.

Tarra-Bulga National Park experiences a cool temperate to warm temperate climate with high, reliable rainfall typical of the Strzelecki Ranges. Annual rainfall reaches approximately 1,300 to 1,600 millimetres. The sheltered rainforest gullies are significantly cooler and more moist than surrounding cleared areas. Mist is a frequent feature of the rainforest environment.

The Gunaikurnai people have cultural connections to the Strzelecki Ranges. European settlement of South Gippsland required extensive clearing of the Strzelecki Ranges forest from the 1880s, with the dense vegetation presenting a significant obstacle to settlement. The park represents one of the few relatively intact areas of forest remaining in a landscape that was almost completely cleared for dairy farming.

Tarra-Bulga National Park was established in 1909, making it one of Victoria's oldest national parks. The early establishment reflects the recognition of the exceptional rainforest values of the Strzelecki Ranges. A visitor suspension bridge across the Tarra River is a popular feature of the park's walking track infrastructure.

The Suspension Bridge walk is the signature attraction, crossing the Tarra River via a swing bridge in the heart of the rainforest. The Tarra Falls walk provides access to a beautiful waterfall in the rainforest setting. The Bulga Rainforest walk traverses magnificent myrtle beech rainforest with tree ferns. Lyrebird observation is almost guaranteed on any visit. The atmospheric rainforest environment with its sounds, smells, and visual character is the primary attraction.

Tarra-Bulga National Park has well-developed visitor infrastructure including picnic areas with tables and toilets, well-marked walking tracks, and a visitor centre at the Bulga section. The park is accessed from the South Gippsland Highway via Yarram and Tarra Valley Road, or via Grand Ridge Road from Mirboo North. The park is approximately 250 kilometres from Melbourne.

Conservation management focuses on protecting the cool temperate rainforest from weed invasion and maintaining the ecological connectivity of the park with the broader Strzelecki conservation landscape. Invasive weeds are controlled along track margins. The management of the endangered spot-tailed quoll population and other threatened species is an ongoing priority. The park's isolation within an agricultural landscape creates edge effects including predation pressure and weed invasion.
