Araucaria bidwillii Hook. |
Araucaria bidwillii, the bunya pine, is a large evergreen coniferous tree in the plant family Araucariaceae. It is found naturally in south-east Queensland Australia and two small disjunct populations in north eastern Queensland's World Heritage listed Wet Tropics. There are many old planted specimens in New South Wales, and around the Perth, Western Australia metropolitan area. They can grow up to 30–45 m. (98–147 ft) The tallest presently living is one in Bunya Mountains National Park, Queensland which was reported by Prof. Robert Van Pelt in January 2003 to be 169 feet (51.5 meters) in height.
The bunya pine is the last surviving species of the Section Bunya of the genus Araucaria. This section was diverse and widespread during the Mesozoic with some species having cone morphology similar to A. bidwillii, which appeared during the Jurassic. Fossils of Section Bunya are found in South America and Europe. The scientific name honours the botanist John Carne Bidwill, who sent the first specimens to Sir William Hooker in 1843.
Native in Queensland, historically trees were found in populations recorded as abundant and widespread in suitable habitats of South East Queensland and Wide Bay-Burnett (regions). In these regions of Queensland the natural ecosystems growing Bunya Pines have sustained European agricultural occupation and have been fragmented now into the areas of the Blackall Range, Bunya Mountains, upper Brisbane River reaches and upper Mary River valley. Natural ecosystems having Bunya pines are found again approximately 1,000 km (620 mi) to the north, in the wet tropics region of north eastern Queensland. There the species natural populations are rare and restricted. Two outlying restricted populations are known in the Cannabullen Falls and Mt. Lewis areas.
