Greater Hawke National Park: Old Growth Forest Protected Landscape & Regional Atlas

Greater Hawke National Park is primarily known for its extensive old growth forest, which represents some of the last remaining intact woodland ecosystems in the South West of Western Australia. This region is part of the globally significant biodiversity hotspot known as the Southwest Australian Floristic Region. The park's old growth forests contain towering karri and jarrah trees, along with diverse understory vegetation that supports numerous species. Its proximity to D'Entrecasteaux National Park creates a larger conservation corridor that protects wildlife movement and maintains ecological processes across the landscape.

Greater Hawke National Park was officially proclaimed on 8 December 2004 when the Parliament of Western Australia passed legislation creating the park as Class A Reserve No. 47878. This establishment came as part of a significant expansion of the state's national park system on that same day, with 19 new national parks proclaimed simultaneously. The park's creation represented the culmination of efforts to protect remaining old growth forest areas in the South West region, many of which had been under threat from logging and agricultural development. The decision to establish the park as a Class A reserve reflected the high conservation value placed on the area's forests and biodiversity. Prior to formal protection, the land had been managed for various purposes, and the park's creation represented a shift toward prioritising ecological preservation. The Bibulman people's traditional ownership of the land was recognised in the park's establishment, acknowledging the long history of Aboriginal connection to this landscape.

The landscape of Greater Hawke National Park is characterised by rolling terrain covered in tall old growth forest, typical of the South West region's more elevated terrain. The park sits within the Warren bioregion, an area known for its relatively high rainfall compared to surrounding parts of Western Australia, which supports lush forest growth. The forest canopy is dominated by species such as karri and jarrah, two of Western Australia's most iconic hardwood trees that can reach considerable heights and form impressive vertical structure. The forest floor supports a diverse understory of shrubs, ferns, and other plants that thrive in the moist, shaded conditions beneath the canopy. The landscape includes creek lines and drainage features that carry water through the forest, providing habitat for aquatic species and contributing to the overall ecological complexity of the area. The park's terrain varies in elevation, creating microclimates and diverse habitat conditions across its extent.

The nature of Greater Hawke National Park reflects the exceptional biodiversity of the Southwest Australian Floristic Region, one of the world's recognised biodiversity hotspots. The park's old growth forest provides critical habitat for numerous plant and animal species, many of which occur nowhere else on Earth. The forest structure, with its large old trees, fallen logs, and diverse ground cover, creates a complex habitat that supports species at multiple trophic levels. The Warren bioregion receives sufficient rainfall to support tall forest ecosystems, distinguishing it from the more arid surrounding regions. The park's protected status ensures that ecological processes continue without significant disturbance, allowing natural fire regimes, nutrient cycling, and species interactions to function. The old growth character of the forest means that trees have reached maturity and developed the structural features such as hollows and dead branches that provide nesting sites for birds and mammals.

Greater Hawke National Park supports wildlife populations typical of South West old growth forests in Western Australia. The forest provides essential habitat for numerous bird species, including cockatoos, parrots, and honeyeaters that rely on tree hollows for nesting and the forest canopy for feeding. Mammals including various possum and bat species use the forest for shelter and food, while reptiles and invertebrates occupy the forest floor and understory layers. The combination of old trees with hollows, fallen logs, and diverse plant life creates the complex habitat structure that supports this diversity. The park's connection to the larger D'Entrecasteaux National Park to the south allows for wildlife movement across a broader landscape, which is important for species that require large home ranges or seasonal movement corridors. The Bibulman people's traditional connection to the land includes historical relationships with wildlife that formed part of their cultural practices and food resources.

Greater Hawke National Park plays an important role in conserving the old growth forest ecosystems of the South West region, an area that has experienced significant land clearing and modification since European settlement. The park's Class A reserve status provides strong legal protection that prevents downgrading or excision of the land. As part of a network that includes the adjacent D'Entrecasteaux National Park, the park contributes to landscape-scale conservation that protects ecological processes across a larger area. The Southwest Australian Floristic Region is recognised internationally for its high number of endemic species, many of which are under threat from habitat loss and climate change. Protecting areas like Greater Hawke National Park helps maintain populations of these species and preserves the evolutionary processes that generated such diversity. The park also protects waterways and catchment areas that feed into broader river systems, providing benefits that extend beyond the park's boundaries.

Greater Hawke National Park is situated on land traditionally owned by the Bibulman people, whose connection to this landscape spans thousands of years. The Bibulman are part of the broader Noongar cultural grouping of South West Western Australia, a group with deep ties to the forest, woodland, and wetland environments of the region. Traditional Aboriginal use of the area would have included hunting, gathering, and ceremonial activities that were integrated with the seasonal patterns of plant and animal availability. The park's establishment recognised these traditional connections, acknowledging the ongoing cultural significance of the land for Bibulman people. Understanding the cultural context adds depth to the park's significance beyond its ecological values, highlighting that this landscape has been important to human communities for much longer than the 2004 national park designation.

Greater Hawke National Park preserves some of Western Australia's last remaining old growth forest, offering visitors the opportunity to experience towering karri and jarrah trees in a relatively natural state. The park provides two campsite locations for those wishing to stay overnight and immerse themselves in the forest environment. Its location adjacent to the larger D'Entrecasteaux National Park creates opportunities for extended exploration across connected protected areas. The park's Class A reserve status reflects its high conservation value and ensures permanent protection of its ecological values. The Bibulman people's traditional connection to the land adds cultural significance to the landscape.

Greater Hawke National Park can be visited throughout the year, though the South West of Western Australia experiences a Mediterranean climate with cool, wet winters and warm, dry summers. The forest is most lush during spring and early summer when rainfall is typically higher and wildflowers add colour to the understory. Summer months offer warm conditions suitable for camping and bushwalking, though fire risk may lead to park closures during periods of extreme heat. Winter brings cooler temperatures and increased rainfall, which can make some tracks muddy but also brings a different character to the forest as watercourses flow and the landscape remains green. The best time to visit depends on what visitors hope to experience, with spring offering excellent wildflower viewing and summer providing the most accessible conditions for extended outdoor activities.
