Biriwal Bulga National Park is an Australian national park in New South Wales. It is approximately 45 km northwest of Taree and 60 km west of Port Macquarie on the Bulga Plateau. The Indigenous Australians in the local neighbourhood speak the Birpai language. The people were dispersed throughout the land in smaller clan groups, with the most prominent being the Winmurra people. It contains one of the few rainforest remnants on the Bulga Plateau. As of 2004, there were no recorded threatened plant species. The most prevalent danger are wild dogs, particularly dingoes. Foxes and pigs are also a concern for the park's natural catchment. The main type of fire is vegetation fire, most commonly known as bushfire.
Biriwal Bulga National Park was one of the areas affected by the 2019–2020 bushfire season in Australia. The fire burned during the periods of mid-December to mid-January. Torrential rain and large thunderstorms helped firefighters to contain the spread throughout the park.
Bacteria
Within the National Park, there are some bacteria that pose potential problems to the wildlife which inhabit it. Chlamydia pecorum is a bacterial pathogen dangerous to the wildlife, in particular koalas. This pathogen is an infectious disease which harms koalas and potentially could cause fatality. Currently there are nine recognised sites in Biriwal Bulga that are significant to the local Indigenous population. A further two potentially significant sites are being investigated with the help of the Indigenous community around Biriwal Bulga.
