Manly Lagoon Dredging Project – Review of Environmental FactorsPrepared for Manly and Warringah CouncilsScientific NameCommon NameGoannaEPBCActTSCActFMActRecords SourceBioNetKEY: E1 / E2 = Endangered (TSC Act); E = Endangered (EPBC Act); E4 = Presumed Extinct (TSC Act); CE =Critically Endangered (EPBC Act, Fisheries Management Act 1994); FV = Fish Vulnerable (FisheriesManagement Act 1994); FE = Fish Endangered (Fisheries Management Act 1994); FP = Fish Protected(Fisheries Management Act 1994); V = Vulnerable (TSC Act and EPBC Act).The species listed in Table 5.9 were mapped using the BioNet mapping tool (whereapplicable) and the following threatened fauna species were noted to be in proximity (within1.5km) to the proposed works site:Red-crowned Toadlet (Pseudophryne australis);Australian Fur-seal (Arctocephalus pusillus doriferus); andGrey-headed Flying-fox (Pteropus poliocephalus).The terrestrial field survey conducted by Warringah Council indicated that none of the abovethree species were present at the proposed works site. No terrestrial or avian fauna specieslisted as threatened under the TSC Act and/or EPBC Act were identified within the proposedworks area during the terrestrial field survey (Warringah Council, 2010). For the full list offauna species recorded at the works site by Warringah Council during the field survey seeAppendix N.Warringah Council also identified potential habitat at the works site for two threatenedspecies including the Glossy Black-Cockatoo (Calyptorhynchus lathami) and the BlackBittern (Ixobrychus flavicollis). However, the Seven Part Tests for these two speciesconcluded that the proposal is unlikely to result in a significant impact on local populations ofthreatened fauna as listed on the TSC Act (Warringah Council, 2010; Appendix N).Protected BirdsOn 29 October 2009 two colonies of Little Pied Cormorant (Phalacrocorax melanoleucos)were found to be nesting by environmental scientists from Warringah Council in twoCasuarinas on the edge of Manly Lagoon, and in the vicinity of the lower portion of dredgingworks. This species is listed as Protected under the National Parks and Wildlife Act 1974(NPW Act).These nesting sites were verified by a subsequent site visit by Cardno personnel on 12November 2009. Field observations, photos and maps are provided in Appendix L. Map 1from Appendix L showing the location of the two nesting sites is reproduced in Figure 5.11.2 July 2010 Cardno (NSW/ACT) Pty Ltd 86H:\Doc\2010\Reports.2010\Rep2580v4.doc
Manly Lagoon Dredging Project – Review of Environmental FactorsPrepared for Manly and Warringah CouncilsFigure 5.11: Nesting Sites of Little Pied Cormorant Colonies at Manly Lagoon, 12 November 2009One of the two colonies was at the eastern end of the end of Riverview Parade (Figure 5.11)and consisted of two Little Pied Cormorant nests, both with young in the nests. There werebetween four and six adult Little Pied Cormorants present at this colony. This nesting site isdirectly on the bank of the Lagoon, at the downstream extremity of the proposed dredgingworks, as shown in Figure 5.11. For full details of field observations at this site seeAppendix L.The second nesting location was behind 46 Riverview Parade, where one Little PiedCormorant was sitting on a nest. Warringah Council observed about eight adult Little Pied2 July 2010 Cardno (NSW/ACT) Pty Ltd 87H:\Doc\2010\Reports.2010\Rep2580v4.doc
