Burrinjuck Nature Reserve

The Burrinjuck Nature Reserve is a protected nature reserve on the south west slopes of New South Wales, Australia. The  reserve is located adjacent to the Burrinjuck Dam, with  of the reserve located on the northern side of the reservoir, and the remaining  located on the southern side of the reservoir to the northeast of Black Andrew Nature Reserve. It includes land formerly managed as the Burrinjuck State Forest and Burrinjuck State Recreation Area.

History
The reserve was established in 1984. Initially, it consisted of  of land, but  and about  of the former Burrinjuck State Recreation Area were added in 2001 following the passage of the , and a further  were added to the western side of the reserve in 2006.

The entire reserve has been subject to bushfire, though some parts of the reserve have experienced fire more often than others. A particularly severe fire in the summer of 1972–1973 burnt around  of land in the area. Recent work demonstrated that the vegetation communities in the reserve appear to be quite resilient to fire.

Public facilities
The only public facilities in the reserve are the Hume and Hovell Track and a track that leads to the summit of Mt. Barren Jack from Burrinjuck Waters State Park.

Threatened species
Two species listed on the  are known to exist in the reserve. The Yass daisy is listed as vulnerable, and the crimson spider orchid is listed as endangered. There are thought to be about 100 crimson spider orchid plants in the reserve, which constitute one of four known populations of the species in New South Wales.

Grevillea iaspicula meets the criteria for listing as Critically Endangered in NSW under the . Seven sub-populations of the plant are known to occur in the Wee-Jasper–Burrinjuck area; one of these sub-populations is located in the reserve.
