Lake Buchanan is different from all other salt lakes in Australia because it occurs at a high elevation - on the Great Dividing Range. The lake is shallow and the water tends to be brackish.[1] The land around the lake is used for grazing.[1]

Lake Buchanan contains a number of significant species which are newly discovered and most probably endemic.[2] These include the Lake Buchanan button grass, fringing rush, Lake Buchanan fringe rush, Lawrenica buchananensis (Malvaceae), and Buchanan's fairy shrimp. The Lake Buchanan blue bush is a threatened species belonging to the genus Chenopodium.
