Knowledge of Tetratheca juncea at the site
101 At the time of the offence, Mr Gordon knew that the site contained a number of different species of flora and fauna. Mr Gordon told the NPWS investigator on 25 October 2001:
"I've got a detailed species list which is quite extensive. I mean, to put it into context there has been 201 native species of flora identified on the site."
102 In particular, Mr Gordon was aware, and had been since 1996 or 1997, that Tetratheca juncea was on the site and that the plant was a vulnerable species. At the time of clearing in sites A to E and clearing the tracks at the site, Mr Gordon had received advice from Mr Geoff Winning, a flora and fauna consultant, about how to identify Tetratheca juncea. In addition, Mr Gordon had read a number of reports identifying potential Tetratheca juncea habitat at the site. These reports included:
· Flora Assessment: Lots 1 and 4 Cowlishaw Road, DP 24886, Redhead NSW by Dr Anne Clements & Associates Pty Limited (April 1999) (the Clements report). Figure 7 of that report identifies the location of Tetratheca juncea habitat at the site.
· Report by Mr Robert Payne dated November 2000 entitled "Lake Macquarie Tetratheca juncea Conservation Management Plan Final".
· Redhead natural area study prepared by Don Caldwell Consultants, Enviro Sciences Pty Limited, May 1991.
· Fauna Survey and Assessment 10A Cowlishaw Road, Redhead NSW by Dr Leong Lim, Countrywide Ecological Service (April 1998).
· Redhead Survey 24-25 September 1998 by Dr Arthur White (September 1998).
103 The Clements report had a detailed species list for areas of the site. Mr Gordon had been in possession of the Clements report since 1999, had read it on a number of occasions and had told NPWS investigators that he understood it. Mr Gordon did not agree with the boundaries that Dr Clements had established for Tetratheca juncea or with Dr Clements' population estimates. Mr Gordon stated that he formed this opinion on the basis of Mr Winning's work and his own knowledge of the site from "site investigation by traversing those areas, marking them with survey tape and establishing the boundaries by the use of a flail mower."
104 Mr Gordon's reliance on Mr Winning's work needs to be qualified. Mr Gordon did not, prior to commencing the slashing, clearing or excavating on the site, request Mr Winning to map locations of Tetratheca juncea on the site or to prepare a report on the subpopulation of Tetratheca juncea on the site. Subsequently, as part of the process of preparation of a development application, Mr Winning was requested and did prepare a report dated October 2001. However in preparation of that report, Mr Winning still did not survey any of the Tetratheca juncea habitat areas identified in the Clements report or do any other survey of Tetratheca juncea at the site.
105 What Mr Gordon did ask Mr Winning to do was to estimate the abundance of Tetratheca juncea in certain areas of the site that Mr Gordon himself had identified as containing Tetratheca juncea. These were areas that Mr Gordon had not already cleared. Mr Winning did not himself do any field work in the cleared areas.
Knowledge of obligation in relation to threatened species
106 At the time of the commission of the offences in August to December 2001, Mr Gordon was aware that "there was an obligation on myself not to harm or cause harm to threatened species or their habitats."
107 In relation to the clearing on the site, Mr Gordon told NPWS investigators on 25 August 2001, "The activities have been a direct result of my independent judgment as to what we are entitled to do or what we have a duty to do under the various legislation."
108 Mr Gordon was aware of the need for a licence under s 91 of the NPW Act if they were to pick Tetratheca juncea but did not apply for a licence as Mr Gordon considered the clearing would not encroach on Tetratheca juncea.
