Calperum Station (reserve)  Calperum Station, also known as Calperum Reserve, is a protected area located in the east of the Australian state of South Australia about north west of the town of Renmark and about east of the state capital of Adelaide. The property is a de-stocked pastoral (sheep) station managed by the Australian Landscape Trust. It is managed for public benefit as a site for habitat and species conservation, scientific research and public education. Most of the property is listed as "critical habitat" for a threatened bird species, the black-eared miner. It also includes a major part of the Riverland Ramsar Site. Calperum Station is part of a larger reserve system known as the Riverland Biosphere Reserve. The reserve is located on the north side of the Murray River, bounded to its western side by the Taylorville Station reserve and the Gluepot Reserve. The reserve covers an area of and was described in 2008 as follows: Some 95% of Calperum Station is covered by Mallee vegetation communities growing on the east-west red brown dunes of the Loxton-Parilla Sands. The remaining 5% is occupied by the Murray River floodplain which includes 4 wetlands: Merreti; Woolpolool; Clover; and Woolpolool Swamp, which are part of the 30,600 hectare ‘Riverland’ Ramsar site. The purpose of the reserve is the protection of "Listed Critical Habitat" for the black-eared miner bird species, in conjunction with both the Taylorville Station reserve and the Gluepot Reserve. The reserve, along with Taylorville Station, is also reported as being "important for the conservation of the nationally vulnerable malleefowl ("Leipoa ocellata"), the regionally vulnerable bush stone-curlew ("Burhinus grallarius") and the nationally vulnerable southern bell frog ("Litoria ramiformis")." The reserve is one of the "key components of the Riverland (formerly Bookmark) Biosphere Reserve." Calperum Station is sometimes referred to as Calperum Reserve. Calperum Station consists of three separate pastoral leases - Calperum, Calperum Road and Yubalia. These were purchased in 1993 by the Chicago Zoological Society, using funds obtained both from the McCormack Foundation and the Australian Government. The leases were subsequently transferred by deed of assignment to the Director of National Parks to hold in trust. Since 2003, the reserve is managed along with the Taylorville Station reserve under contract by the Australian Landscape Trust Association Inc. (ALT).
