Summary - City of Gosnells

Vegetation 51per 100 m 2 ). All of these vegetation units have been reduced by at least 90% (as estimated for vegetation ofthe eastern side of the Swan coastal plain as a whole by Government of Western Australian, 2000). Theremaining patches of this vegetation are threatened by clearing, weed invasion and frequent fire.The Corymbia calophylla – Kingia australis woodlands on heavy soils (FCT 3a) occur on a variety oflandforms where shallow sand over mud aquitards perch rainwater and contribute to seasonal waterloggingin this vegetation. This FCT had a mean species-richness of 58.9 spp. per 10 m x10 m site in Gibson et al.(1994). Plant taxa that were almost always associated with this FCT in Gibson et al. (1994) were Banksiadallanneyi var. dallanneyi, Desmocladus fasciculatus, Kingia australis, Mesomelaena tetragona, Philothecaspicata and Xanthorrhoea preissii. Also present at high consistency levels in this unit were Borya scirpoidea,Cyathochaeta avenacea, Hakea ceratophylla, Pericalymma ellipticum and Synaphea petiolaris. Althoughsome of the taxa consistently present in FCT 3a may also be present in the two other Marri (Corymbiacalophylla) units (Table 5.2), each of these FCTs have been shown to have floristic and habitat factors thatclearly distinguish them from each other (English and Blyth, 2000a). There are approximately 83 ha of FCT3a remaining at 10 documented sites that are located at Pinjarra, Waroona, Byford, Mundijong, Wungong,Forrestfield and Kenwick (English and Blyth, 2000a). The Forrestfield occurrences of this TEC total 4.6 ha(4 ha and 0.6 ha in two reserves). The known Kenwick occurrence is 0.75 ha and is located in the BrixtonStreet Reserve (BFS 387).Table 5.2: Native taxa recorded in at least 50% of sites in the three Corymbia calophylla TECs of the Eastern SCP inGibson et al.
