Fauna at risk

Fauna at risk While still existing in other parts of WA, the Bilby: a charismatic marsupial distinguished by its “bunny-like ears”, has sadly been lost from the SWCC Region forever and more threatened species are at risk of being lost. There are 2,203*(Ala.org.au, 2018) fauna species in the SWCC Region, 58 of which are threatened, seven…

Flora at risk

Flora at risk Western Australian flora is arguably some of the most unique in the world and has fascinated wildflower enthusiasts for generations. 78 flora species are threatened (DBCA, 2018) in the SWCC Region i.e: flora species which are declared as rare or likely to become extinct under the Wildlife Conservation Act 1950. There are 13,903…

Loss of native vegetation

Loss of native vegetation Clearing of native vegetation (historical, present and future) remains one of the major threats to terrestrial biodiversity in the south west. It contributes to the the physical loss of flora, fauna and their habitat; and reduces the resilience of the remaining vegetation and biodiversity to pressures such as weed invasion, vegetation…

Vegetation cover change since 2000

Vegetation cover change since 2000 From European settlement to the year 2000 vegetation cover on the Swan Coastal Plain (the area between the ocean and the scarp) had been reduced by 80%, leaving only a small proportion remaining (35,727 ha).1 (Ecotones, 2018). In the short 17 years since, a further 28.5% of remaining vegetation cover…

Land for Wildlife

Land for Wildlife Land for Wildlife is a voluntary conservation program to encourage and assist private landholders to provide habitat for wildlife on their property. Within the SWCC Region, 1,516 properties are under Land for Wildlife covering a total of 26,364 hectares. In May 2016, the Department of Parks and Wildlife entered a Partnership Agreement…

Vegetation fragmentation

Vegetation fragmentation Vegetation fragmentation is caused by clearing which separates vegetation into smaller patches of vegetation.  These patches are therefore no longer continuous and are disconnected by barriers such as roads, urban development, agriculture and mining, plantations. This can isolate species and restrict the movement of flora, fauna and genetics across the landscape, making species…

Threatened Aquatic Species

Threatened Aquatic Species Between 2001 and 2017, the list of threatened aquatic species (including wetland dependent birds) in the South West NRM region has increased from five to 23. This represents a 360% increase in aquatic species listed as threatened between 2001 and 2017. These are species deemed either rare or at risk of extinction,…

Smooth Marron Populations

Smooth Marron Populations While past translocations of Smooth Marron (Cherax cainii) have resulted in an expansion of its distribution northward and eastward, there has also been a decline in its inland range and local abundances due to water quality decline and loss of habitat.  The populations have deteriorated over the past 40 years.  Monitoring of…

Aquatic invertebrates in forests

Aquatic invertebrates in forests Index 1: 69% of 29 stream sites within conservation reserves or state forest across the SWCC NRM region between 2005 and 2011 received an average AusRivAS rating indicating they were in good condition. Index 2: Condition stable. 82% of 11 stream sites monitored between 2005 and 2016, had the same average…

Whales

Whales Conservation Dependent humpback, endangered blue and endangered southern right whales have shown consistent, seasonal use of important habitat in the southwest region with an apparent steady increase in humpback sightings. Seasonal observations undertaken between 2005-2017 have resulted in a total of 22,600 humpback, blue, and southern right whale sightings recorded from Pt Picquet. Of…
