❓ Dr Woollard questions the Department of Conservation and Land Management (CALM) regarding research into threatened cockatoo species in South-West WA, potential habitat destruction, and the impact of logging and mining. The response details research activities, denies tree felling for research, and downplays the impact of current forest management practices.

(2)(a)-(d) The Department of Conservation and Land Management is a co-operative partner with the Birds Australia WA Group in the recovery plan for Carnaby's Black-Cockatoo. The recovery plan involves a small research component. The Department is the lead agency in implementing the recovery plan for Muir's Corella. A small research project examining the taxonomic relationships between this species and other corella species in southwest WA is currently in progress. The Carnaby's Cockatoo project extends over the species' full range from the Murchison River south to Albany and east to Cape Arid, but is primarily focused on areas subject to broad-acre cereal cropping, all of which are outside of the tall eucalypt forests of the southwest. The Muir's Corella project is focused on its restricted range within farming lands from Frankland west to Lake Muir and north to Kulikup and McAlinden. This species seldom enters the forested areas within its range, preferring the open grazing lands and watercourses of the Blackwood and Tone River systems. No trees were felled during any of the Department's research activities into Carnaby's Cockatoo and Muir's Corella. (3)(a) Not applicable. (b) Not applicable. (4) Not applicable. (5) Not to date. (6) Forest management includes strategic planning for the development of a comprehensive, adequate and representative conservation reserve system, and managing the ongoing supply of habitat trees on State forest subject to logging. Logging and mining have reduced the number of hollow-bearing jarrah and marri trees. The specific impact of this loss on large hollow-using species such as cockatoos is not known. However, for cockatoos, such as the Red-tailed Black Cockatoo which occurs in the forest but is not threatened, the extreme situation in the agricultural areas provides a contrasting reference to that in the managed forest. The inland race of the Red-tailed Black Cockatoo persists in agricultural areas despite removal of hollow-bearing trees from extensive areas of the landscape. In contrast, the forested area of the State has extensive tree cover, there are extensive large and small reserves, and on the areas that are logged (but not on mined areas), trees and stands of trees are retained for fauna habitat. A number of studies have been undertaken on the Forest Red-tailed Black Cockatoo, which is not listed as a threatened species, including investigations into nest hollows. It is not considered that the current forest management practices are having a significant impact on the conservation status of Western Australia's cockatoo species.

(6) Forest management includes strategic planning for the development of a comprehensive, adequate and representative conservation reserve system, and managing the ongoing supply of habitat trees on State forest subject to logging. Logging and mining have reduced the number of hollow-bearing jarrah and marri trees. The specific impact of this loss on large hollow-using species such as cockatoos is not known. However, for cockatoos, such as the Red-tailed Black Cockatoo which occurs in the forest but is not threatened, the extreme situation in the agricultural areas provides a contrasting reference to that in the managed forest. The inland race of the Red-tailed Black Cockatoo persists in agricultural areas despite removal of hollow-bearing trees from extensive areas of the landscape. In contrast, the forested area of the State has extensive tree cover, there are extensive large and small reserves, and on the areas that are logged (but not on mined areas), trees and stands of trees are retained for fauna habitat. A number of studies have been undertaken on the Forest Red-tailed Black Cockatoo, which is not listed as a threatened species, including investigations into nest hollows. It is not considered that the current forest management practices are having a significant impact on the conservation status of Western Australia's cockatoo species.
