The programs are prepared in addition to Regional Management Plans to provide detailed information and guidance for the management and protection of certain exploited or threatened species (e.g. Kangaroos, Noisy Scrub-bird and the Rose Mallee). This program provides a brief description of the appearance, distribution, habitat and conservation status of flora declared as rare under the Western Australian Wildlife Conservation Act (Threatened Flora) and poorly known flora (Priority Flora) in CALM's Central Forest Region and makes recommendations for research and management action necessary to ensure their continued survival. By ranking the Declared Rare Flora in priority order according these requirements, Departmental staff and resources can be allocated to those taxa most urgently in need of attention. Priority Flora that are under consideration for declaration as rare are also dealt with, but to a lesser extent than the Declared Rare Flora. However, the information available should assist in the ongoing work of assessment of their conservation status. This Program has been approved by the Executive Director, Department of Conservation and Land Management, the Conservation Commission and the Minister for the Environment. Approved programs are subject to modification as dictated by new findings, changes in species' status and completion of recovery actions. Information in the Plan was accurate at August 1998. 3 ACKNOWLEDGEMENTS I would like to thank a number of people who have assisted during the prolonged task of producing this document. Past and present Central Forest Region, Regional and District nature conservation operational staff, including Andrew Webb, Mitch Davies, Meredith Soutar, Rob Turner, Caroline Brocx, Rob Brazell, Greg Voigt, Charlie Broadbent and Bob Fitzgerald, have all contributed field information to the population data presented here. Greg Keighery and Neil Gibson from CALMScience provided comment and feedback on the numerous drafts as did Ken Atkins, CALM Wildlife Branch and Russel Smith, Environmental Protection Branch. Andrew Brown and Val English from WATSCU provided comments, feed back and advice in the early stages of the document. Sue Carroll answered our innumerable questions arising from the WA Herbarium flora databases and Anne Cochrane from the Threatened Flora Seed Centre assisted in field work, training our staff in seed collection techniques and by providing information used in the threat matrix analysis. A big thank you must go to Graham McCutcheon for his many years of field work and collections across the region which provided the basis for many of the population details contained in the plan and for penning the Botanical History of the region. Finally special mention must be made concerning the contributions of Scott Wood who commenced as Project Coordinator, compiling the early datasets and first draft of the document before transferring (he must have known something!) and Andrew Horan who picked up the project and has followed it through to completion over the last two years.
