Summary - City of Gosnells

Vegetation 65Small areas of this vegetation inhabited seasonally waterlogged slopes of humic sand to peaty sand (betweenseasonally waterlogged or inundated clay flats and low dunes) in Precincts 1 and 2. This vegetation gradedupslope into either Melaleuca preissiana low woodland and degraded Banksia menziesii low woodland orCorymbia calophylla low forest.Associates of this vegetation included: Banksia littoralis, Burchardia bairdiae, Calandrinia sp. Kenwick(G.J. Keighery 10905), Drosera nitidula, Eutaxia virgata, Grevillea pinnatifida subsp. pinnatifida,Hydrocotyle diantha, Hypocalymma angustifolium Mud Habitat Variant (C.Tauss 1850), Juncuscaespiticius,*Lotus subbiflorus,U Lepidosperma longitudinale, UMeeboldina roycei, Melaleuca preissianaU,Microtis atrata, Schoenus asperocarpus, Schoenus discifer, *Parentucellia viscosa, Patersonia occidentalisvar. angustifolia, Pimelea imbricata var. major, Schoenus rigens, Tremulina tremula, Tribonanthes australis,Verticordia densiflora subsp. densiflora, Verticordia lindleyi subsp. lindleyi, Viminaria juncea.Vegetation Unit SL6: Hypocalymma angustifolium and other low, open to mid-dense shrubs over alienunderstorey. This was a degraded vegetation unit that was probably originally similar to other units such asSL2 or SL3. A number of areas of this vegetation unit in Precinct 2 were interspersed amongst vegetationthat was in better condition.Vegetation Unit SL7: Tecticornia indica subsp. bidens - Tecticornia lepidosperma low open shrubs overother succulents and naturalised alien grasses and herbs understorey. This was a very degraded vegetationunit that was probably originally similar to ST4. Areas of this vegetation in Precinct 2 were interspersedamongst vegetation that was in better condition.Vegetation Unit RS1: Meeboldina cana - Chaetanthus aristatus mid-dense, species-rich rushes, sedges andopen herbs and patchy Viminaria juncea tall open shrubs.This vegetation inhabited muddy floodplains in Precinct 2. It was generally in very good to good condition.There were also some areas where grazing and trampling of soils appeared to have allowed weed invasionand the regrowth was less species-rich.There were also much smaller, much more degraded stands of this vegetation in Precinct 1.Associates of this vegetation included: Acacia lasiocarpa var. lasiocarpa sens. strict., Acanthocarpuscanaliculatus, Baeckea sp.
