Lake Gladstone is the largest permanent wetland in the Kimberley region of northern Australia. However until recently, it was trampled by cattle, its waters muddied, and the balance of native vegetation exposed to invasive weeds.
In 2005, an agreement between neighbouring property managers and the Australian Wildlife Conservancy lead to restoration of this unique wetland. A stock-excluding fence was erected, followed by weed control measures. The results have been spectacular.
To visit Lake Gladstone now is to experience a richly biodiverse place, alive with the sounds of birdsong and waterfowl. Ducks and grebes call from the water, darters and egrets from surrounding perches, while brolgas take wing and call from overhead. Crakes and swamphens dabble among the reeds along the water's edge, and bush birdsong fills the trees.
This recording documents a single morning at the lake, beginning in the darkness of predawn. Over the following three hours, the sun rises, casting long shadows over the waters and reedbeds. The soundscape subtly transitions from the songs of nocturnal crickets and cries of waterbirds in the dark, to the daytime activity of songbirds.
This is a single, unedited recording. At three hours, it is also a long one. However it remains interesting the whole time, presenting the biodiversity of the place and allowing you to hear the success that collaborative conservation initiatives can achieve.
The making of this recording has been supported by the Australian Wildlife Conservancy and their staff at the adjoining Mornington-Marion Downs Station Wilderness Camp.
