Nestled just 3 km from Pemberton in Western Australia’s South West, Gloucester National Park is a sanctuary of towering karri forests, rich biodiversity, and captivating natural beauty. Spanning approximately 8,500 hectares, the park offers visitors a tranquil escape into nature, with opportunities for bushwalking, birdwatching, and picnicking amidst the majestic trees.

Historical Significance

The park’s centrepiece, the Gloucester Tree, stands as a testament to the region’s history. Named in honour of the Duke of Gloucester’s visit in 1946, this towering karri tree was transformed into a fire lookout in 1947, with a platform installed 58 metres above the ground. While climbing the Gloucester Tree is currently unavailable due to maintenance, its presence remains a symbol of the area’s heritage and the nearby Aerial Adventure high ropes course and surrounding cycle and walk trails give plenty of reasons to visit the park.

Geology and Morphology

Situated within the ancient landscapes of the Warren River Valley, the park’s terrain is characterized by undulating hills, deep gullies, and fertile soils that support the lush karri forests. The region’s geology, comprising ancient granite and gneiss formations, has been sculpted over millions of years, creating a diverse and dynamic environment.

Flora: The Majestic Karri Forests

Dominating the park are the karri trees (Eucalyptus diversicolor), among the tallest hardwoods globally, reaching heights of up to 90 metres. These giants create a dense canopy, under which thrive a variety of plant species, including:

• Peppermint trees (Agonis flexuosa), providing shelter for small mammals and birds.
• Banksias, whose flowers support nectar-feeding birds and insects.
• Sheoaks (Allocasuarina spp.), offering a distinctive contrast to the karri giants.

Fauna: A Haven for Wildlife

The park’s rich habitats support a diverse array of wildlife:

• Birds: Species such as the purple-crowned lorikeet, red-tailed black cockatoo, and splendid fairywren are commonly observed, especially during the spring and summer months when the karri canopy bursts into white flowers, attracting flocks of birds.
• Mammals: While sightings are rare, the park provides habitat for native mammals like the western ringtail possum and quenda.
• Frogs: The moist gullies and creeks are home to various frog species, including the motorbike frog (Litoria moorei), known for its distinctive call resembling a revving motorbike engine.
