Overview

Muir-Byenup System. 05/01/01; Western Australia; 10,631 ha; 34°29'S 116°43'E. Nature Reserve. A suite of partly inter-connected lakes and swamps of varied size, salinity (saline to fresh), permanence (permanent to seasonal) and substrate (peat and inorganic), in an internally-draining catchment. The open lakes are used for moulting by thousands of Australian Shelduck Tadorna tadornoides and for drought refuge by tens of thousands of other ducks, while the sedge/shrub-dominated swamps support an important population of Australasian Bittern Botaurus poiciloptilus and three types of nationally vulnerable orchids. Vegetation communities of the site's wet flats are among the few remaining in non-coastal parts of southwestern Australia and the site has some of the largest natural sedgelands in Western Australia. The site is used for nature conservation, but agriculture, notably grazing of domestic sheep and cattle and tree plantations, occurs in adjoining lands. Illegally released feral pigs cause considerable damage to vegetation and soil. Ramsar site no. 1050. Most recent RIS information: 2001.
