Flora 43The continued existence of Grevillea thelemanniana in its natural habitat is dependent on theconservation and appropriate management of the fragmented populations in this area. As it appears to bea bird-pollinated species, its reproduction is probably also dependent on the maintenance of local birdhabitats. This species is eligible for listing as Threatened Flora (B.J. Keighery, P. Olde, R. Makinson,pers. comm.).9. Verticordia lindleyi subsp. lindleyi (Myrtaceae) (Priority 4). This small shrub is endemic to theeastern SCP; but most of its previous habitat has been cleared. Kenwick has significant populations inthe Greater Brixton Street Wetlands. Several plants were recorded in two blocks in the MKSEA.Notes:1. Isopogon drummondii (P3) was recorded by Cardno BSD (2005) in the MKSEA, but that record was notconfirmed in the current survey, probably due to lack of access to the block where Cardno BSD (2005)recorded it. This block will require full survey at a later date if development is proposed for it.2. Acacia lasiocarpa var. bracteolata (long peduncle variant) (P2) was was also recorded by Cardno BSD(2005) in the MKSEA, but not in the current survey. Acacia lasiocarpa var. lasiocarpa sens. strict. wasthe only Acacia recorded in the current survey in the area where Acacia lasiocarpa var. bracteolata(long peduncle variant) was recorded by Cardno BSD. It is probable that the Cardno BSD (2005) recordis this variety.Table 4.3: Summary of the Flora of National and State Significance recorded in the MKSEA Field SurveySpeciesStatus1.

Verticordia lindleyi subsp. lindleyi P44.2.3 Flora of Regional Conservation Significance found in the MKSEAApart from EPBC-listed, DRF and Priority Species, EPA Guidance Statement 51 (EPA, 2004b) andGovernment of Western Australia (2000b) define a third set of criteria under which flora taxa (i.e. species,sub-species or varieties) may have conservation significance. This set of criteria is referred to in this reportas ‘regional conservation significance’ (see Section 4.1.1 above).The MKSEA was found to have about 97 flora taxa that can be considered as regionally significant underthese criteria (Appendix B). Most of these are also in BFS 387 and/or BFS 53 (Appendix A). The regionallysignificant taxa that are in the MKSEA and not in BFS 387 or BFS 53 are Dielsia stenostachya, Eucalyptusdecipiens subsp. decipiens, Eucalyptus gomphocephala, Gastrolobium ebracteolatum, Lepidosperma sp.Kenwick (C.Tauss 2598), Leucopogon strictus, Schoenus subflavus subsp. subflavus, Schoenusunispiculatus, Tricoryne aff. elatior (C. Tauss 1905) and Trymalium odoratissimum subsp. odoratissimum.The most numerous regionally significant taxa in the MKSEA could be grouped under the following criteria.Tauss, C. and Weston, A.S. (2010). The flora, vegetation and wetlands of the Maddington-Kenwick Strategic Employment Area.A survey of the rural lands in the vicinity of the Greater Brixton Street Wetlands.
