Abstract

The objective of this report is to improve the scientific basis for the GSS by providing information on the role of pines on the ecology of Carnaby‘s Black-Cockatoos in GSS area. This report also addresses how this species might be affected by the removal of pine from the Gnangara, Pinjar, and Yanchep pine plantations.

Part I provides background information on the ecology and conservation biology of Carnaby‘s Black-Cockatoos and their association with the Swan Coastal Plain and the pine plantations in the GSS. It also provides a brief statement of the key issues associated with the impact of pine removal on this species.

Part II describes various aspects of the ecology of Carnaby‘s Black-Cockatoos in the GSS area based on field research in 2009 and previous studies.

Part III examines how the removal of pine may affect Carnaby‘s Black-Cockatoos and potential responses, provides an initial risk assessment framework, evaluates pine removal as a possible controlled action under the Environmental and Biodiversity Conservation Act 1999, and addresses landscape management and restoration for Carnaby‘s Black-Cockatoos conservation.
