CALM Information Management Branch ii FOREWORD Western Australian Wildlife Management Programs are a series of publications produced by the Department of Conservation and Land Management (CALM). 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 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 Esperance District and makes recommendations for research and management action necessary to ensure their continued survival. By ranking the Declared Rare Flora in priority order according to 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 in less detail than the Declared Rare Flora. However, the information contained in this Program should assist in the ongoing work of assessing their conservation status. This Program has been approved by the Executive Director, Department of Conservation and Land Management, the National Parks and Nature Conservation Authority 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 this Plan was accurate at 1992. iii ACKNOWLEDGEMENTS The following persons are thanked for their assistance and helpful discussions: Specialist advice and, on occasions, specimen identifications were sought and promptly given by the following: R. Baker (Hakea), M.I.H. Brooker (Eucalyptus), A.P. Brown (Orchidaceae), A.R. Chapman (Leucopogon), R.J. Chinnock (Eremophila), R.S. Cowan (Acacia), R.J. Cranfield (Papilionaceae, general), M.D. Crisp (Chorizema, Daviesia), A.S. George (Dryandra), S.D. Hopper (Eucalyptus), L.A.S. Johnson (Eucalyptus), G.J. Keighery (Daviesia, Gratiola, Opercularia), N.S. Lander (Olearia), T.D. Macfarlane (Papilionaceae), N.G. Marchant (Darwinia), B.R. Maslin (Acacia), A.E. Orchard (Dampiera), M. Pieroni (Dryandra), J. Powell (Leucopogon), B.L. Rye (Rhamnaceae), M.E. Trudgen (Angasomyrtus, Baeckea), H. White (Thysanotus), and P.G. Wilson (Asteraceae, Rutaceae). CALM staff who provided assistance were: ESPERANCE - K. Tiedemann, B. Haberley, T. Florisson, S. Winton, M. Paxman, P. Bastian, R. France; WESTERN AUSTRALIAN HERBARIUM - V. Hamley, S. Curry, S. Carroll, M. Falconer, I. McPharlin, B.S. Mahon, P. Spencer, W. Hanks, C.S. Fang; WILDLIFE BRANCH - K. Atkins, M. O'Donoghue, D. Stefoni and J. Riley. Others who provided assistance include S. Grein and C.J. Robinson. Of particular assistance to this project was the Western Australian Herbarium database under the supervision of A.R. Chapman. This system allows scrutiny of rare flora collections held in PERTH, and hard-copy printouts for field and other use. iv ABBREVIATIONS Alb Albany AR Aboriginal Reserve Aug Augusta Bldr Boulder BR Bruce Rock Brktn Brookton Bsltn Busselton CALM Department of Conservation and Land Management Car Carnamah Cbk Cranbrook Cool Coolgardie Cor Corrigin Crw Coorow Degen.
