[1][2] Lake Buchanan is different from all other salt lakes in Australia because it occurs at a high elevation - on the Great Dividing Range.

[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.
