could continue relatively unchanged for hundreds, possibly thousands of years to come. Brown Lake Brown Lake is a perched lake which retains its water due to a layer of leaves lining the lake floor and is of cultural significance to the Quandamooka people of Stradbroke Island. The precipitated matter eventually forms an impermeable layer, preventing water from percolating to the water table. Eighteen Mile Swamp The Eighteen Mile Swamp is the largest of its kind in the world and, in particular, is a fine and extensive representation of a coastal freshwater swamp. It is unusual for its size and dimensions (very long and narrow), covering and is considered to be very young (500-6,000 years) compared with similar swamps. On 27 March 2011, the area was declared a national park, named Naree Budjong Djara National Park, My Mother Earth, by the Quandamooka people, the Traditional Owners of Minjerribah (North Stradbroke Island), who are engaged in its joint management with the Queensland State government. The wetland is in close proximity to the extensive Enterprise Mine. The Eighteen Mile Swamp is home to many endangered, rare species, including the vulnerable Cryptocarya foetida whose habitat is the notophyll vine forest found at the foot and lower slope of parabolic high dunes on the west of the wetland. These high dunes on the west of Eighteen mile swamp provide excellent examples of long parabolic dunes migrating across North Stradbroke island from the south-east to the north-west. This migration has buried earlier positions of the west coast escarpment to form complex hydrological systems with the ancient dunes (estimated at up to 300,000 years old). No comparative examples of the phenomenon are seen on Moreton and Fraser Islands. Myora Springs and Myora Creek Swamp Myora Springs is a unique wetland site on the north west side of North Stradbroke Island, of particular cultural significance to the Quandamooka people as a sacred gathering site, and is also a declared fish habitat area. Myora Springs is known to be essential habitat for the vulnerable water mouse (Xeromys myoides) and the endangered swamp orchid (Phaius australis). Lake Kounpee Another perched lake, Lake Kounpee was partially drained after sand mining operations breached the impervious layer in 1987. CRL spent over $300,000 in the 10 years following this in attempts to fix the damage, and now acknowledge they can not repair the damage to the lake – "turning a clear freshwater lake
