Mount Druitt Commuter Car ParkReview of Environmental FactorsThree mature specimens of Forest Red Gum Eucalyptus tereticorni are located in anarrow strip of soil less than 2 metres wide between the Mount Street footpath andthe Proposal site.The bulk of vegetation on site occurs in the strip of vegetation along the North Paradefrontage. This strip of vegetation is approximately 10 metres deep and is broken by thedriveway leading onto the site from North Parade. The area to the west of this drivewayand immediately to the east is composed of weeds. The more easterly area of this stripof vegetation along North Parade shows a reduction in the density of weeds and theoccurrence of some native species of trees and groundcovers. These native speciesinclude six specimens of Grey Box Eucalyptus moluccana from 1 - 3.5 metres tall, aspecimen of Spotted Gum Corymbia maculata (5 metres), a specimen of ForestSheoak Allocasuarina torulosa (3 metres) and a single Swamp Oak Casuarina glauca.Native groundcovers in this strip of vegetation along North Parade are restricted touncommon specimens of Three Awned Spear Grass Aristida and are dominated bynumerous weed species.Photo 6-3Example of saplings in south-east corner of siteOf the five species of native tree species recorded on or near the proposed car park,four species are considered native to Western Sydney. Allocasuarina torulosa is notconsidered local and may be planted. The Eucalyptus tereticornis specimens occurringalong the Mount Street boundary could also be considered to be planted judging fromtheir even height, regularly spacing and linear occurrence. Of the native tree speciesoccurring on site, Eucalyptus tereticornis, Eucalyptus moluccana and Corymbiamaculata are characteristic species of Cumberland Plain Woodland ( CPW).The resilience of the site is considered very low, with probably limited soil stored seed.Exotic plant species dominate the understorey and ground layer and account for thedominant protective foliage cover on vegetated areas of the site. The diversity of weedspecies is low and no noxious weeds have been observed on site.6.7.2. Potential impactsThe three mature Eucalyptus tereticornis along Mount Street adjacent to the easternboundary would be kept and incorporated into landscaping of the proposed car park.All vegetation in the southern section of the site would be removed including all of thesmall native trees.KMH-2010123a REF Rev 4 doc.
