    Artificial nests support cockatoos in Great Southern

    18/05/2016 8:00 AM
    • 100 artificial nesting hollows for Borden, Newdegate and Lake King
    • Population of Carnaby's cockatoos across Western Australia is about 40,000 

    One hundred artificial nesting hollows will be installed in trees in the Great Southern at Borden, south of Newdegate, and to the east of Lake King to provide breeding habitats for Carnaby's cockatoos.


    Environment Minister Albert Jacob said that establishing the artificial hollows was an important part of conservation of the species.


    The specifically designed artificial hollows have been successful at Badgingarra and resulted in a 20 per cent increase in the number of Carnaby's cockatoo fledging once the hollows were installed.


    "In fact, it has proven so successful at Badgingarra, Parks and Wildlife staff have recorded some Carnaby's choosing to nest in these specifically designed hollows over natural hollows," Mr Jacob said.


    "I am keen to see if we can achieve similar breeding results with the nesting hollows in the Great Southern."


    The artificial hollows are made from durable plastic culvert pipe and are based on measurements taken from almost 3,000 natural tree hollows.  The tubes are 400 millimetres in diameter, at least one metre deep and are installed a minimum of four metres above the ground.


    The Minister said the project built on recovery actions in the Carnaby's cockatoo recovery plan and was supported by the Carnaby's cockatoo recovery team with strong support from local landholders.


    Carnaby's Black-Cockatoo is one of three black cockatoos species only found in south-west Western Australia, extending from the Murchison River to Esperance; and inland to Coorow, Kellerberrin and Lake Cronin.


    The draft Perth and Peel Green Growth Plan for 3.5 million proposes to install an additional 700 nesting hollows in the area from Eneabba to Ravensthorpe as part of its conservation program for the species.
