PART ONE: INTRODUCTION1. The Need For ManagementWestern Australia has a unique flora world renowned for its diversity <strong>and</strong> high level of endemism. WACENSUS, <strong>the</strong>database of plant names for <strong>the</strong> State, lists 12 306 current taxa (species, subspecies, varieties <strong>and</strong> phrase-names)(January 1997), with <strong>the</strong> total likely to exceed 13 000 once botanists have completed survey<strong>in</strong>g, search<strong>in</strong>g <strong>and</strong>describ<strong>in</strong>g <strong>the</strong> flora. A significant proportion of <strong>the</strong> Western Australian total is concentrated <strong>in</strong> <strong>the</strong> south-west of <strong>the</strong>State, where <strong>the</strong>re is also a large number of endemics due to a long history of isolation <strong>and</strong> climatic <strong>and</strong> geologicalstability (Hopper 1979). Accord<strong>in</strong>g to Briggs <strong>and</strong> Leigh (1996) <strong>the</strong> State has 45.9 percent of <strong>the</strong> Australian total ofthreatened, rare or poorly known plant species, with 79 percent restricted to <strong>the</strong> south-west. Nearly 2 000 WesternAustralian taxa are currently listed as threatened or have been placed on <strong>the</strong> Department of Conservation <strong>and</strong> L<strong>and</strong>Management’s (CALM) Priority <strong>Flora</strong> List because <strong>the</strong>y are rare or poorly known (K. Atk<strong>in</strong>s, personalcommunication).Although some plants are rare because of <strong>the</strong>ir requirement for a specific restricted habitat, <strong>the</strong> majority have becomerare or threatened because of <strong>the</strong> activities of humans. Extensive l<strong>and</strong> clear<strong>in</strong>g <strong>and</strong> modification of <strong>the</strong> environment hasresulted <strong>in</strong> <strong>the</strong> ext<strong>in</strong>ction of some species <strong>and</strong> threatens <strong>the</strong> survival of many o<strong>the</strong>rs. Cont<strong>in</strong>ued l<strong>and</strong> clear<strong>in</strong>g, plantdiseases (particularly due to Phytophthora species), exotic weeds <strong>and</strong> pests, road works, urbanisation, graz<strong>in</strong>g bydomestic stock <strong>and</strong> <strong>in</strong>creas<strong>in</strong>g sal<strong>in</strong>ity cont<strong>in</strong>ue to threaten <strong>the</strong> flora.The State Conservation Strategy, Wildlife Conservation Act 1950, <strong>and</strong> Conservation <strong>and</strong> L<strong>and</strong> Management Act 1984provide <strong>the</strong> guidel<strong>in</strong>es <strong>and</strong> legislative basis for <strong>the</strong> conservation of <strong>the</strong> State's <strong>in</strong>digenous plant <strong>and</strong> animal species.CALM is responsible for <strong>the</strong> adm<strong>in</strong>istration of <strong>the</strong> Wildlife Conservation Act, <strong>and</strong> hence, is responsible for <strong>the</strong>protection <strong>and</strong> conservation of flora <strong>and</strong> fauna on all l<strong>and</strong>s <strong>and</strong> waters throughout <strong>the</strong> State. Section 23F of <strong>the</strong> Actgives <strong>the</strong> M<strong>in</strong>ister responsible for <strong>the</strong> Act statutory responsibility for <strong>the</strong> protection of those plant taxa declared to berare (i.e. threatened taxa).This Wildlife Management Program collates <strong>the</strong> available biological <strong>and</strong> management <strong>in</strong>formation on <strong>the</strong> <strong>Declared</strong> <strong>Rare</strong><strong>Flora</strong>, <strong>and</strong> Priority One, Two <strong>and</strong> Three (poorly known) taxa of CALM's <strong>Geraldton</strong> <strong>District</strong>, as at 21 October 1996. In1996, 302 extant taxa were classified as <strong>Declared</strong> <strong>Rare</strong> <strong>Flora</strong> <strong>and</strong> a fur<strong>the</strong>r 27 species were listed on <strong>the</strong> Schedule asPresumed Ext<strong>in</strong>ct. In addition to those that were declared rare, 1 639 taxa were listed on CALM's Priority <strong>Flora</strong> List asat October 1996. The majority of <strong>the</strong>se taxa require fur<strong>the</strong>r detailed survey to accurately assess <strong>the</strong>ir conservation statuswhile o<strong>the</strong>rs are rare, but not currently threatened, <strong>and</strong> require ongo<strong>in</strong>g monitor<strong>in</strong>g. Brown et al. (1998) provideillustrations of <strong>Declared</strong> <strong>Rare</strong> <strong>Flora</strong> as at 1998, discuss <strong>the</strong> conservation of Western Australia's threatened species <strong>and</strong>review <strong>the</strong> relevant legislation, <strong>and</strong> <strong>the</strong> policy, research <strong>and</strong> management activities of CALM.The <strong>Geraldton</strong> <strong>District</strong> covers some 137 338 km 2 of which some has been cleared for agriculture on <strong>the</strong> south-westernside. Figure 1 shows <strong>the</strong> location of <strong>the</strong> <strong>Geraldton</strong> <strong>District</strong> <strong>in</strong> relation to <strong>the</strong> CALM Management Regions of <strong>the</strong> State.2. Objective of <strong>the</strong> ProgramThe objective of this program for <strong>the</strong> <strong>Geraldton</strong> <strong>District</strong> is:To ensure <strong>and</strong> enhance, by appropriate management, <strong>the</strong> cont<strong>in</strong>ued survival <strong>in</strong> <strong>the</strong> wild of populations of <strong>Declared</strong> <strong>Rare</strong><strong>Flora</strong> <strong>and</strong> o<strong>the</strong>r plants <strong>in</strong> need of special protection.It aims to achieve this by:provid<strong>in</strong>g a useful reference for CALM staff <strong>and</strong> o<strong>the</strong>r l<strong>and</strong> managers for <strong>the</strong> day-to-day management <strong>and</strong>protection of <strong>Declared</strong> <strong>Rare</strong> <strong>Flora</strong> populations <strong>and</strong> populations of o<strong>the</strong>r taxa which are poorly known <strong>and</strong> may beat risk;direct<strong>in</strong>g Departmental resources with<strong>in</strong> <strong>the</strong> Region to those species most urgently <strong>in</strong> need of attention;11
