Flora 334. Flora4.1 Flora Desktop StudyA comprehensive search of the flora taxa of conservation significance (at the national, state and regionallevels) that are known to have distributions that may include the MKSEA (or habitats similar to those foundin the MKSEA) was conducted in the literature and the databases of rare flora maintained by relevantagencies. The main aim of this search was to predict the occurrence of the taxa of conservation significancemost likely to occur within the study area and so assist the targeted search and recognition of these taxa inthe field survey. Apart from the names of these taxa and their listed conservation significance codes, otherrelevant information (where available), such as geographic distribution, locality records, growth form,habitat and flowering time, was also included in the list compiled (Appendix A: Table A.1). The sources ofthese data are listed below.1. The list of Flora of National Conservation Significance was compiled from the Threatened FloraDatabase of the DEWHA (2008a).2. The list of Flora of State Significance (the taxa listed as Declared Rare Flora and Priority Flora inWestern Australia) was compiled from searches of three Western Australian DEC Flora Databases byDEC staff. The parameters for each search are shown below.a. The Threatened (Declared Rare) Flora Database, for records in the rectangle defined by thecoordinates 32 0 00’ 00” - 32 0 02’20” S and 115 0 58’ 00” - 116 0 00’ 10” E.b. The Western Australian Herbarium Specimen Database (WAHERB) for records in the rectangledefined by the coordinates above; andc. The Declared Rare and Priority Flora List Database for the locations Beckenham, Brixton,Cannington, Forrestfield, Gosnells, High Wycombe, Kenwick, Kewdale, Maddington, Maida Vale,Orange Grove, Perth Airport, Wattle Grove and Welshpool.There is doubt (based on discrepancies between specimen collection coordinates and stated location inWestern Australian Herbarium [WAH], in 2008, on recorded habitats or on examination of WAHcollections) that none of the eight Priority taxa - Acacia lasiocarpa var. bracteolata long pedunclevariant (G.J. Keighery 5026), Acacia oncinophylla subsp. patulifolia, Aotus cordifolia, Banksiapteridifolia subsp. vernalis, (syn. Dryandra pteridifolia subsp. vernalis), Lasiopetalum bracteatum,Templetonia drummondii, Tetratheca sp. Granite (S. Patrick 1224) [aff. hirsuta] and Thysanotus anceps- has been recorded previously within the Swan Coastal Plain part of the DEC database search area.3. The list of Flora of Regional Significance was compiled from the records of other field surveysconducted in the vicinity of the MKSEA, including Keighery and Trudgen (1992), Keighery andKeighery (2000); Government of Western Australian (2000); Cardno BSD (2005), Tauss (2007a),Keighery and Tauss (2008) and Tauss (2009). All geographical distributions were checked on FloraBase(Western Australian Herbarium, 2008, 2009).4. Much of the data about localities, distributions and flowering times of many of these taxa were providedby the Western Australian DEC database search result and Atkins (2006, 2008). Other data of form,features and habitats were added from Paczkowska and Chapman (2000) and Western AustralianHerbarium (2007, 2008, 2009). Additional data were compiled from examination of herbariumspecimens and their labels in the Western Australian Herbarium, consultations with other botanists,Marchant et al. (1987), Hoffman and Brown (1998) and relevant parts of the Flora of Australia andHow to Know Western Australian Wildflowers series.Tauss, C. and Weston, A.S. (2010).
