(b) if the application is in respect of development on land that is, or is a part of, critical habitat or is likely to significantly affect threatened species, populations or ecological communities, or their habitats - a species impact statement prepared in accordance with Division 2 of Part 6 of the Threatened Species Conservation Act 1995."
78 The reference in s 78A(8)(b) of the EPA Act to "development…that is…or is likely to significantly affect threatened species, populations or ecological communities, or their habitats" is a jurisdictional fact in the sense that if the court decides, on the evidence before it, that that was the situation, and if the development application was made without an accompanying species impact statement, then the power to grant development consent was not enlivened: Gedeon v Commissioner of the New South Wales Crime Commission [2008] HCA 43, 236 CLR 120 at [43];Timbarra Protection Coalition Inc v Ross Mining NL [1999] NSWCA 8, 46 NSWLR 55 at [34], [94]; Woolworths Ltd v Pallas Newco Pty Ltd [2004] NSWCA 422, 61 NSWLR 707 at [105], [188]; Corowa v Geographe Point Pty Ltd [2007] NSWLEC 121, 154 LGERA 117 at [35], [51] (Jagot J). In this sense, the Court is the judicial ecologist.
79 Section 4(1) of the EPA Act defines terms appearing in s 78A(8)(b) by reference to definitions in the Threatened Species Conservation Act 1995 (TSC Act). Section 4(1) of the TSC Act defines "threatened species, populations and ecological communities" to mean species, populations and ecological communities specified in Schedules 1, 1A and 2 of the TSC Act. "Habitat" means "an area or areas occupied, or periodically or occasionally occupied, by a species, population or ecological community and includes any biotic or abiotic component". Schedules 1, 1A and 2 of the TSC Act categorise threatened species, populations and ecological communities as "endangered", "critically endangered" or "vulnerable". A threatened species, population or ecological community is eligible to be listed as "endangered" if, in the opinion of the Scientific Committee constituted under the TSC Act, it is facing a very high risk of extinction in New South Wales in the near future, as determined in accordance with criteria in the regulations: ss 10(3), 12(2) TSC Act. The objects of the TSC Act are stated in s 3 as follows:
"(a) to conserve biological diversity and promote ecologically sustainable development, and
(b) to prevent the extinction and promote the recovery of threatened species, populations and ecological communities, and
(c) to protect the critical habitat of those threatened species, populations and ecological communities that are endangered, and
(d) to eliminate or manage certain processes that threaten the survival or evolutionary development of threatened species, populations and ecological communities, and
(e) to ensure that the impact of any action affecting threatened species, populations and ecological communities is properly assessed, and
(f) to encourage the conservation of threatened species, populations and ecological communities by the adoption of measures involving co-operative management."
80 Section 78A(8)(b) operates at all times between lodgement and determination of the development application. If the consequence of amending the application is to bring the development within or outside s 78A(8)(b), the section operates in its terms on and from the amendment. Any ameliorative measures proposed in the application as determined are to be taken into account in deciding that question: Corowa at [50], [56].
81 In the present case, the "development" of which s 78A(8)(b) speaks was for a subdivision into five rural-residential lots of a little over one hectare each and a community title lot of about 7 hectares, together with an access road.
82 In s 78A(8)(b), "likely" means "a real chance or possibility", whereas "significantly" means "important", "notable", "weighty" or "more than ordinary": Corowa at [52]; Plumb v Penrith City Council [2002] NSWLEC 223 at [22] (Pearlman J); B T Goldsmith Planning Services Pty Ltd v Blacktown City Council [2005] NSWLEC 210 at [59] (Pain J); Oshlack v Richmond River Council (1993) 82 LGERA 222 (Stein J).
83 In deciding whether the development is likely to significantly affect a threatened species or ecological community, it is mandatory to take into account the matters listed in s 5A of the EPA Act. However, the Court is not limited to those matters nor does a positive finding on any matter in s 5A require a finding that a species impact statement was required: Corowa at [52]; Plumb at [36] - [37]. In the present case, there is an issue as to whether the previous version of s 5A or the current version, which commenced on 31 October 2005, applies in the Court's assessment of whether a species impact statement was required.
84 The previous s 5A, with its eight part test, was as follows:
" 5A Significant effect on threatened species, populations or ecological communities, or their habitats
