Findings - Eastern pygmy-possum
38We were taken to the south-western corner of the site and the location of the proposed resource recovery activity. This area contains a dense stand or thicket of mature Banksia ericifolia assumed by the ecologists to have escaped the 2005 fire. We were shown a number of tubes designed to provide shelter for the Eastern Pygmy-possum. Ms Ashby's tubes were of cardboard construction and Mr Fanning's were made from PVC pipes. It was in this general area that Ms Ashby found up to 12 individual Pygmy-possums sheltering in the tubes.
39We accept that with the benefit of the site inspection, the expert evidence and considering s 79C(1)(b) of the EPA Act as to "the likely impacts of that development, including environmental impacts on..the natural..environment(s)....in the locality" ,we are satisfied that the impact of the proposal on the Eastern Pygmy-possum is unacceptable for a number of reasons.
40First, and while we acknowledge that the habitat area for the Eastern Pygmy-possum is within an area of the site that is not affected by a management zone in the SIP, this does not in any way preclude the consideration required by s 79C(1)(b) of the EPA Act.
41Second, the basis on which the management zones, including the background studies, were created needs to be fully understood. After reading the 2003 Connell Wagner Flora and Fauna Report, it is unsurprising that the area on the site set aside for development was determined. Neither the Australian Museum Business Services' survey in 1997 nor the 2003 surveys conducted by Connell Wagner found any Eastern Pygmy-possums. Based on potential habitat, Figure 8.2(e) the 2003 Connell Wagner Flora and Fauna Report maps the Eastern Pygmy-possum habitat within the site but to the eastern portion of the applicant's lot (rather than the south-western part of the site where the prime Banksia thicket habitat is located). We note that the south-western part of the site is where the majority of the Eastern Pygmy-possums were subsequently found.
42We accept that, for the reasons stated in the 2003 Connell Wagner Flora and Fauna Report, including the difficulty of trapping the animals, the nature of the traps (Elliot traps), the relatively limited extent of the surveys, and the fact that the surveys were conducted before the 2005 fire, the management zones in the POM were determined on the best information available at the time but ultimately were not particularly accurate.
43Third, the most recent surveys support Ms Ashby's evidence there is a resident breeding population, most likely located in or near the prime Banksia thicket in the area of the proposed development. Appendix D of the 2005 Andrews Neal Species Impact Statement includes the s 5A assessment of the Eastern Pygmy-possum. This states that four individuals were found on the applicant's land. Two individuals were captured and another found in a nest box in the Banksia thicket on the southern part of the development site. The remains of another individual were found some distance away in a fox scat. In addition two individuals of this species were also caught by Andrews Neil ecologists on an adjacent property immediately to the south of the subject site in 2004.
44These survey results needs to be compared to the recent survey work undertaken by Ms Ashby where she installed 100 specially designed passive tube traps throughout the southern section of the proposed development site and the full extent of the Habitat link zone to the north and throughout the Riparian/Habitat zone and Aboriginal heritage zones on the eastern portion of the site. She states that the density of the traps was the same for all areas.
45What cannot be disputed is that Ms Ashby found up to nine individuals within the proposed development site with another three found sharing a single tube within about 20 m to the east of the proposed development site. She relevantly states that "the disproportionately high numbers in the development area reflect a deliberate choice for the development area by the animals rather than a reflection of sampling bias."
46The evidence from the parties' ecologists confirms the Scientific Committee's finding #4 in that the Eastern Pygmy-possum is difficult to detect. However, the evidence from Ms Ashby's 'tubes' is that up to nine individuals have been found in the area proposed to be cleared for the development, with another three found close by. While it is not known if these were separate individuals, this appears to be a significant new finding given the Scientific Committee's finding #5.
47Fourth, we are not satisfied that the question in s 5A(1) of the EPA Act as to "whether there is likely to be a significant effect on threatened species, populations or ecological communities, or their habitats" has been satisfactorily addressed. The earlier comments on the Eastern Pygmy-possum in the 1997 Australian Museum Business Services' survey and the 2003 Connell Wagner Flora and Fauna Report, the 2005 Andrews Neal Species Impact Statement have been overtaken by the most recent survey results from Ms Ashby. While we accept that Lloyd J in Davis v Gosford City Council [2012] NSWLEC 62 found, on the evidence before him, that an SIS was not required, this conclusion also pre-dates Ms Ashby's survey results.
48Mr Fanning reviewed these and other ecological studies in the preparation of the 2011 Flora and Fauna Assessment report that accompanied the EIS. He also established 20 nest boxes specifically designed to be attractive to the Eastern Pygmy-possum, however, no individuals were found. Based on this information and the existence of suitable habitat elsewhere, we understand how Mr Fanning arrived at his conclusion that the proposed development would not have a significant impact on the local population of Eastern Pygmy-possum.
49While we accept that Ms Ashby was not required undertake an assessment in accordance with s 5A of the Act, we are satisfied that her oral evidence and the substance of her report legitimately raise the question of whether there is likely to be a significant effect on a threatened species, population, ecological community or their habitats.
50Fifth, in regards to Mr Fanning's proposed amelioration measures, we prefer Ms Ashby's evidence as it appears to be supported by the relatively limited scientific literature on the species. In essence, there is a high degree of uncertainty regarding the habits of the species in general, and the demographics of the local population, in particular. We accept that while trapping and relocation appears attractive, it may have unintended and detrimental consequences. We also agree that the opportunities for enhancement of the nearby vegetation are limited.
51Sixth, we do not accept the suggestion that we should take a flexible approach to the application of the POM in regards to the Hibbertia management zone to compensate for the retention of at least part of the Banksia thicket on the southern part of the site that has been set aside for development. While we accept that the designation of management/ development zones in the POM was based on the best information available at the time, we also accept that the underlying reason for the preparation of the POM was to try and achieve a balance between areas where development can proceed (cl 1.3.1 of the POM) and areas of biodiversity value that should be protected (cl 1.3.2 of the POM). The proper balance, in our view, needs greater consideration that can be given as part of the assessment of a single development application. Clearly, a more considered strategic approach is required if any adjustment of the existing management zones is to be contemplated.
52For these reasons, we find that the proposal, pursuant to s 79C(1)(b) of the EPA Act, will likely unacceptably impact on the Eastern Pygmy-possum in the locality. We also find that the proposal is inconsistent with cl 24(b) in that the proposal does not "protect ecologically significant land"
53In our view, the likely impact on the Eastern Pygmy-possum warrants the refusal of the application.
