The second limb: Is this "new" approach likely to lead to compliance with cl 2.2.2.2?
1038 On the balance of probabilities, and even if, contrary to my findings above, VicForests were to conduct its forestry operations in the Scheduled Coupes using less intensive silvicultural methods, such as those foreshadowed in the 31 May 2019 Harvesting and Regeneration Systems document, I am not persuaded this will lead to any different or better compliance with cl 2.2.2.2, and I am satisfied that in any event VicForests is not likely to comply with cl 2.2.2.2 in the conduct of its forestry operations in the Scheduled Coupes, so as to conserve biodiversity values, specifically, the conservation of the Greater Glider. In reaching this conclusion, I have relied on the following matters:
(a) the applicant's submissions, which I accept, that most of the "new" methods are not relevantly materially different, in terms of their impact on the Greater Glider, from the three existing silvicultural methods used by VicForests in its forestry operations, including in the Logged Coupes, and therefore the findings I have made about compliance in the Logged Coupes are not rendered inapplicable to the proposed forestry operations in the Scheduled Coupes;
(b) Dr Smith's evidence;
(c) aspects of Dr Davey's evidence;
(d) the Castella Quarry example: see [1132]-[1156] below; and
(e) the matters to which I have referred above as "structural or organisational" features, which lead me to find that (1) VicForests is not carefully evaluating management options which avoid "wherever practical" serious damage to the Greater Glider and (2) VicForests is not applying the precautionary principle as defined in the Code to conserve the Greater Glider in the CH RFA region.
1039 As I noted above at [314]-[353] on the evidence adduced at trial, as part of its suite of silvicultural systems moving forward, VicForests proposes to use four kinds of silvicultural systems: clear-felling and seed tree operations; variable retention 1; variable retention 2; and the "selection harvest system."
1040 The applicant's closing written submissions described these methods, based on the evidence, and VicForests did not in its closing reply submissions contend that there was anything inaccurate about that description, or about the applicant's evidence references supporting that description. It made other contentions which I address elsewhere in these reasons, especially about the uncertainties attaching to assertions about how forestry operations will be conducted (if at all) in the Scheduled Coupes. Accordingly, I am satisfied what is set out in the applicant's closing submissions at [69]-[85], read with descriptions of the systems in the May 2019 Harvesting and Regeneration Systems document, is accurate. My findings here combine what is in Annexure A to the May 2019 Harvesting and Regeneration Systems document, and what is in the applicant's submissions at [69]-[85].
1041 The May 2019 Harvesting and Regeneration Systems document describes clear-fell and seed tree retention as follows:
Clearfelling/seed tree operations
• Most suited to uniform stands of tall wet eucalypt forests, i.e. Ash regrowth forests, which require a receptive seedbed and substantial gap sizes for effective regeneration.
• Increasing retention of seed trees and recruitment of future habitat trees within the coupe area; indicatively up to 10 trees per hectare across coupe area.
• Primary focus for retention is surrounding forests and connectivity through existing or new corridors.
1042 The applicant submits the following, which I accept:
The "clearfell" method is defined in the Code as a silvicultural method of harvesting a coupe whereby all merchantable trees, apart from those to be retained for wildlife habitat, are removed (CB 6.9 p11). Ordinarily about 25% of a coupe is retained, taken up by SPZ, stream buffers, and habitat retention, and that area contributes towards the general area retained (RRH instruction CB 3.4.33 p7; T316.13-27, 318.24-34; 318.41-47). Examples of clearfelled coupe is New Turkey Spur - Greendale coupe (CB 4.7.1, p17) and Golden Snitch (CB 3.4.36, p 8 (yellow outline)).
The "seed tree retention" method is defined in the Code as an even-aged silvicultural system in which all live trees are felled apart from a number of uniformly distributed trees retained to provide seed for regeneration and habitat (CB 6.9 p17). An example of a coupe logged by the seed tree retention method is Mount Despair, Glenview coupe (CB 4.2.1 on p91, bottom photo).
In the May 2019 Harvesting and Regeneration Systems document, the first proposed method is "clearfelling and seed tree operations" (CB 12.2, pdf p 21). The new systems document states that clearfell will remain "an important part of VicForests' operations" in uniform regrowth Ash forests (p 21). It provides for 30% of tree cover to be retained across the gross coupe area (on average). Thus "clearfelling and seed tree operations" provide for only 5% of tree cover to be retained (on average) beyond areas of forest that are not permitted to be felled (e.g. SPZ, stream buffers, and habitat retention). It is not stated anywhere why, if at all, retention of an additional 5% of tree cover will benefit the conservation of biodiversity.
Smith said that both clearfelling and seed tree retention remove all but a small number of trees retained to provide hollows for wildlife or seeds for regeneration and results in the regeneration of a predominantly even-aged regrowth forest. Accordingly, Smith refers to both systems as "clearfelling" in his reports (Smith (2) CB 4.3 p7-8).
Smith said the proposed new clearfelling and seed tree retention system cannot be considered an "adaptive management system" because it has no beneficial effect and exacerbates rather than mitigates the threats to Greater Glider and Leadbeater's Possum (Smith (4) 4.12.1 p14).
This method was retained in the May 2019 Systems document despite VicForests' own expert, Professor Baker, providing advice to VicForests on the earlier March version of the document that clearfelling was problematic and should not remain an important part of VicForests operations (T655.14-30). The references to developing a "broader suite of harvest systems" is aspirational only (CB 12.2 pdf p 21). The new clearfell and seed tree systems are not precluded from use in conjunction with regeneration burns (T305.32-.48).

1043 The May 2019 Harvesting and Regeneration Systems document describes variable retention 1 as follows:
Variable retention 1 system
• Using retention harvesting to ensure older forest elements are retained and recruited in areas available for timber harvesting.
• May comprise aggregated retention (forest patches) or more dispersed retention to support multi-cohort stand development.
• Retention of existing habitat trees and recruitment tree; indicatively 15+ trees per hectare across coupe area.
1044 The applicant submits and I accept:
RRH is not defined in the instruments. It is explained in VicForests' Regrowth Retention Harvesting policy document (CB 3.4.33) and by Mr Paul as involving the retention of forest patches so that more than 50% of the harvested area is located within one tree length of retained forest. The relevant retained forest must be at least 50 years old and remains unharvested for one rotation. The rotation length in Ash forests is nominally 80 years (Paul (2) CB 3.4 p65, at [154], and RRH instruction CB 3.4.33, p7-8).
Examples of coupes logged by RRH are Rocketman and Golden Snitch (CB 3.4.36, pp 4 and 8).
Smith said that traditional RRH has negligible merit for amelioration of current high intensity clearfell logging and burning impacts on Greater Gliders (Smith (1) 4.2.1 p32). Further the coupes that Dr Smith inspected that were logged by RRH were intensively logged with very few, if any, remaining surviving habitat trees (Smith (1) 4.2.1 CB pp68, 71, 74-75, 83, 89).
Davey accepted that the area that is harvested within RRH coupes is clearfelled and "is certainly intensively harvested" (TS 513.18-33).
Woinarski said that his inspections of the Rubicon coupes logged by RRH indicated that survival of the retained habitat was patchy. He provided photographs of the destruction or damage to retained forest patches within or adjacent to harvested areas in these coupes (Rocketman/Houston) (Woinarski (1) CB 4.7.1 at [89] and Figure 2).
Proposed new Variable Retention System 1 is stated to be based on RRH and is similar because it provides for retention principally in patches (CB 12.2, pdf p 22). It refers to the retention of at least 20% of basal area within the net coupe area, but this does not translate to a prescription for application of this method (CB 12.2 p22). Neither of the evaluation sites specified (Skinny Jim 2016 and Puerile 2018) were inspected on the view.
…
Smith's evidence is that the proposed be Variable Retention System 1 provides no improvement over current practice. He said it is poorly defined and is unclear what will happen to retained patches in subsequent harvesting cycles. He said Variable Retention System 2 represents an incremental improvement on Variable Retention System 1 but suffers from the same limitations, for the same reasons he provided regarding Regrowth Retention Harvesting (Smith (4) 4.12.1 p19). More specifically he said that the variable retention systems are not suitable for Ash because they do not specifically protect existing tree hollows or allow for recruitment trees, and any increase in habitat retained is temporary and lost by clearfelling on subsequent rotation, which is too short for development of hollows. He said that the variable retention systems were not suitable for Mixed Species forests either because they use gap clearfelling and regeneration by burning which are not ecologically sustainable and have no natural equivalent in Mixed Species forests (Smith (4) 4.12.1 p19).
(Original emphasis.)
1045 The May 2019 Harvesting and Regeneration Systems document describes variable retention 2 as follows:
Variable retention 2 system
• Well suited to a range of forest types, including mixed species (comprising low elevation and high elevation mixed species forests), where there are hollow bearing trees to be retained to provide for habitat or other values.
• Higher levels of aggregated and dispersed retention across coupe; indicatively retaining 20+ trees per hectare across coupe area.
• Encompasses thinning operations, in terms of harvesting operations in which up to 50% is harvested to release further growth of new cohorts.
1046 The applicant submits and I accept:
Proposed new Variable Retention System 2 provides retention principally in patches and corridors but can also incorporate dispersed retention (i.e. trees dispersed across the coupe). It states that it is principally for areas with high levels of existing habitat trees. It does not have a specified retention percentage nor does it require dispersed retention. However an example is given at CB 12.2 pdf p 24, where approximately 40% of the pre-harvest assessed area was retained. In cross-examination, it was put to Mr Paul that the reference in the description of Variable Retention System 2 to retaining 40%+ of the pre-harvest assessed area includes things like stream buffers and areas otherwise required to be set aside, for example Leadbeater's Possum Zone 1A habitat, and what it does is add another 15% plus or minus to the 25% that is retained as area that is not permitted to be harvested. Mr Paul agreed that was the case (T316.13-27, 318.24-34; 318.41-47). Paul agreed it might be better explained as requiring the retention of 15% of area not otherwise required to be set aside (T319.1-6). If this is the case, then proposed Variable Retention System 2 in fact provides for less retention than proposed Variable Retention System 1, which provides for retention of 20% of the basal areas within the net coupe area. In these circumstances the Court can place little confidence in VicForests' proposed new methods.
(Original emphasis.)
1047 The May 2019 Harvesting and Regeneration Systems document describes the selection harvest system as follows:
Selection harvest system
• Comprises group selection and single tree selection systems, recognising varying levels of selection from single trees to small patches.
• System represents a low intensity method of harvesting where individual or small groups of trees are selected and removed; hence the focus is on selection for high quality sawlogs rather than retention of remaining trees.
• Ideal system for co-existence of selective sawlog harvesting and the sustainable harvesting of apiary products from floral resources.
1048 The applicant submits and I accept:
This method is described at item 1.4 of CB12.2. For this method to be applied, there must first be a density of greater than 13 habitat trees per hectare.
On the view, Smith and Davey said that the habitat in Flute coupe was "as good as it gets" (VT53.41-54.5), having between 8 and 10 habitat trees per hectare. The requirement of 13 habitat trees per hectare as a hurdle which must be met before the method falls for consideration is an unrealistic requirement that will have the result that no or very few coupes will be identified as appropriate for this method. Mr Paul said that he was not aware of any coupe in this case which qualified for the application of this method (Paul, T316.1-.11). Accordingly, the apparent existence of this proposed method is irrelevant to issues in the proceeding both at a TRP level concerning the CHRFA and at a coupe level concerning the scheduled coupes.
1049 The applicant accepts the May 2019 Harvesting and Regeneration Systems document suggests that VicForests will conduct less intensive burns after its forestry operations. These are called in the document "cool to moderate regeneration burns" or "cooler burns". However, the applicant contends that the only likely advantage of that refinement is that a lower number of habitat trees may be damaged or killed. As I have explained earlier, Dr Smith's evidence (which I accept) is that many trees which are left in coupes after forestry operations as "habitat trees" are in fact damaged or killed in the regeneration burns which occur, this negating the purpose for their retention. As I have also explained, that opinion is consistent with what the Court observed on the view about the number of dead and dying habitat trees.
1050 Thus, the applicant contends that if cooler and less intense burns are used more often, the only likely effect of this is to make VicForests more compliant with the objectives to be served from the retention of habitat trees. I agree. Cooler burns may make VicForests more compliant with existing prescriptions, that is all. VicForests did not deal with this issue in its submissions.
1051 There are other aspects of the new systems which seem to perpetuate some of the problems with the existing systems which have been identified by the applicant, in particular by Dr Smith. One is the way that habitat tree prescriptions are applied by reference to the gross coupe area: that is, VicForests does not apply the habitat tree prescription only to the area it proposes to harvest. There is no indication on the evidence that the new systems approach proposes to change this method. It has a real impact on what, if anything, remains in the harvested area, as the applicant's submissions point out:
A number of the prescriptions in the May 2019 Harvesting and Regeneration Systems document, either as to area to be retained or habitat trees to be retained, refer to prescriptions being applied in the gross coupe area. These prescriptions must be understood by reference to the method VicForests uses to draw coupe boundaries. VicForests specifies that gross coupe boundaries must be mapped to include exclusions, buffers and SPZs within the coupe (Paul CB 3.4 at [259]; Coupe Reconnaissance Instruction (3.4.37 pp10 at [9.1], p22-24). This practice necessarily inflates the gross coupe area and may portray that a larger proportion of each coupe is being retained, when in fact the boundaries were simply drawn around forest not permitted to be logged in any event. Likewise, counting of habitat trees retained in gross coupe areas may result in few or no retained habitat trees within the actual harvest unit (Paul, T307.12-17), as observed by Smith at multiple coupes subject of the proceeding (Smith (1) 4.2.1 pp 58 68, 71, 74-75, 83, 89). It is for this reason that Davey said he considered that Mont Blanc coupe had complied with habitat tree prescriptions despite accepting that it had only 2 trees per hectare within the harvest unit (Davey T517.27-44).
The Acheron Kenya coupe is a good example of reliance on existing SPZ or Code prescriptions as the "retained proportion" of the coupe in order to engage in more intensive harvesting in the harvest unit. It was visited on the view. Mr Paul said the coupe was harvested by regrowth retention with 13.4ha net harvested of 28.8 gross, but that coupe boundary includes a substantial area of mapped SPZ in the north (Agreed Map 7.4C; Post Harvest Map 8.2A). Such SPZ together with a stream buffer is what comprised the 53% "of the coupe" that was not harvested (i.e. it would meet the 40% retention method for System 1.3). The effect on the ground was a more intensive operation within the harvest unit, because VicForests counted retained trees in existing SPZ rather than retaining them within the harvest unit. Smith found on Kenya that habitat trees were not scattered across the coupe, were fewer than prescription and were not protected during logging operations with 48% burnt, felled or pushed, and no habitat trees in clumps (Smith (1) 4.2.1 p68).
(Original emphasis.)
1052 Further, as the applicant contends, the benefits of any such modifications to the way the Greater Glider might be able to use, recolonise or remain in the forest subject to harvesting is not apparent. The following part of Mr Paul's evidence in cross-examination illustrates the point, and makes several other points, to which I refer below.
Can I suggest to you that at a broadbrush level, SPZ and stream buffers typically make up 25 per cent of a coupe?---They - they can do, yes.
So if that's the position, what this variable retention system does is it reduces what might otherwise have been clear-felled so that an extra 15 per cent in addition to the buffers and streams is not the subject of intensive forestry operations; is that right?---Sorry, can you repeat that?
So 25 per cent, typically, of a coupe will be taken up by SPZ or stream and floodway areas?---On average, yes.
On average?---Yes.
Just a broadbrush. So what this method does is it adds another 15 per cent plus or minus to that 25 per cent, doesn't it?---In that sense of it being an average, yes.
So what I suggest to you is in terms of an adaptive measure, it might be better explained as being rather than 40 plus per cent of pre-harvest assessed area, plus or minus 15 per cent of area not otherwise required to be set aside?---I guess that's one way of describing it. It's clearly a new method, though, that aims to spread our habitat much more evenly across the coupe area, and include extra area, whilst at the same time provide some timber as well.
And this method has a hurdle of 5 to 12 habitat trees per hectare, doesn't it, for both ash and mixed species?---Yes.
So if 8 to 10 habitat trees is excellent habitat or very good quality - very high quality habitat for Greater Gliders, how is - and that habitat is found, what is it that says that that habitat should be retained in the 15 per cent?---It does say that at least an additional 20 habitat trees retained. So we are about identifying habitat trees and protecting those habitat trees.
But that's across the gross coupe area, isn't it?---Where - wherever they exist.
You see, this method, and the whole of this document, is driven by habitat trees rather than habitat suitable for species, isn't it?---Well, the two are going to be very closely related.
Well, do you understand from what you've read in this case that the habitat requirements, for example, of the Greater Glider are not the same as the habitat requirements for the Leadbeater's possum?---Yes, that's correct.
And how is it that this method is tailored to or takes into consideration the need for the Greater Glider to glide between tall trees and then have a landing tree with a 40 centimetre trunk?---Well, the level - that level of detail is not in here. As we discussed before, this is a somewhat sort of a higher level document. There will be more detailed prescriptions built into it, but Castella as a - Castella coupe as an example left those coupes - those trees approximately 30 to 40 metres apart, I believe, and were all of a reasonable size for that species to move between.
But there's nothing in this document that says, in terms of spacing one should factor in what you've just given in evidence, is there?---No, this document doesn't seem to say that specifically.
And this method, if we can just scroll to the next page, please, this isn't a new method. This - according to the evaluation sites, this has been around since 2013, hasn't it?---What - - -
Turkey Neck and Dogs Back, 2013 and 2017 in reverse order; correct?---Yes. So they're coupes where we have retained for various reasons additional habitat on those coupes.
So this system, if indeed those two sites are evaluation sites, has been around since 2013. There's been one other evaluation site, Turkey Neck in 2017, but it's never been used otherwise, has it?---I don't know that it hasn't been used otherwise. They're the examples.
1053 Another point which this part of Mr Paul's evidence illustrates is that some of these "new" systems are in fact not that "new". Rather, they have been used in forestry operations since at least 2013, but only in an experimental way. That is, there has been no widespread implementation by VicForests of such methods, and despite at least one of these "experimental" coupes (Dogs Back) having been harvested in 2013, six years before the trial of this proceeding, there was no evidence adduced about what could be observed, six years later, in terms of how the forest in that coupe provided any current or potential habitat for the Greater Glider. In other words, once again, the "on the ground" reality, and any "on the ground" benefit to the Greater Glider, was not apparent in the evidence.
1054 Another aspect of this part of Mr Paul's evidence should be highlighted. His response to senior counsel for the applicant that habitat trees and suitable habitat are "very closely related" illustrates in my respectful opinion another of the difficulties of the attitude VicForests brought to these issues. That evidence showed no awareness at all about the complex habitat requirements of the Greater Glider (or any other hollow-dependent species), and involves a denial of the effects of forestry operations. Simply because a tree is called a habitat tree does not make it one. Observations of logged or regenerating coupes, and what are identified as habitat trees, and comparisons with an unlogged forest, indicate it is not rational or reasonable to describe the two situations as "very closely related". That is one of the points being made overall by the evidence of Professor Woinarski and Dr Smith: in some circumstances, there is no substitute for simply retaining the forest without logging it.
1055 The disparity between what can appear in a document such as the May 2019 Harvesting and Regeneration Systems document and what occurs during a forestry operation is further illustrated by what the Court observed in the Greendale coupe on the view. Greendale coupe was a coupe with predominantly tall Ash, and is identified by VicForests as an evaluation site for the first system (clear-fell and seed tree retention) in the May 2019 Harvesting and Regeneration Systems document: in other words, not a "new" method, but said to be a "new" approach to an old method.
1056 In the May 2019 Harvesting and Regeneration Systems document, noting that the clear-fell method will "remain an important part of VicForests operations, predominantly in tall Ash forests", VicForests states (at p 16):
However, as a key part of its focus on developing a broader suite of harvest systems, VicForests is working to:
• restrict use of clear-felling to the uniform regrowth Ash forests
• reduce the use of high intensity regeneration burns
• protect and enhance uneven-aged forest elements.
1057 To that end, one of the prescriptions proposed in this document for Ash forest and for Mixed Species forest is as follows:
Where 2 or less habitat trees per hectare are present, retain at least ≥10 habitat trees (category 2 -3) per hectare.
1058 And another is:
Utilise the 2 - 1 habitat tree retention method to maintain and enhance habitat elements within the harvest areas
1059 The "2 to 1" practice, as Mr Paul conformed in cross-examination, is a practice whereby foresters retain two retention trees, such as (in this region) two 1939 regrowth trees, so that there is, in the future, the possibility of habitat trees forming.
1060 In cross-examination, and also by reference to the post-harvest map for Greendale, Mr Paul accepted that the coupe was entirely harvested by clear-fell method, and no seed trees remained. He also accepted that, in the area that was actually harvested, it was "possible" no habitat trees were retained either. His evidence, looking at the post-harvest map and recalling what was seen on the view, was that at some points in the "buffer" areas - that is, around stream reserves and other features where VicForests is otherwise required to retain the forest - there were parts where the buffer had been "thickened up" beyond the minimum required. In substance, Mr Paul accepted that no trees at all had been left in the harvested area.
1061 This led to another difficulty between the theory of the prescriptions and the practice of their implementation, which was revealed in cross-examination:
The amount of clear-fell area here is 18.4 hectares, isn't it?---Yes.
And if we go - if we look on the other side of the page on the screen, what is said at the foot of what's page 16 of the 31 May 2019 document is that clear-fell and seed tree gaps will not exceed 10 hectares in size. Well, that's certainly been exceeded here in this evaluation coupe, hasn't it?---Yes, it has in this coupe, but certainly moving forward that 10 hectares will be applied.
But, Mr Paul, this is an evaluation coupe for this method, isn't it?---Yes, it is, but it's - it's after the fact. So some elements haven't clearly aligned exactly.
Well, what I suggest to you is what's happening on the ground here is just not matching the document, is it?---Not in this case for that particular area requirement, no.
No. And yet this is - to any reader such as the applicants or any member of the public, if they want to understand what an evaluation site is for this method, the first one mentions Greendale, isn't it?---Yes.
And when we look at Greendale against the criteria we find that it doesn't match up because it has got more than 10 hectares in size that are clear-felled; correct?---Correct.
And it also doesn't have any recruitment trees or any habitat trees, does it?---I'm not sure about habitat trees in the harvested area, but there's potentially some close and contained within the buffers and expanded buffers.
And this method that we're looking at is also a method that is used in this proposed document of 31 May for mixed species as well, isn't it?---Yes, it is.
1062 Thus, in the very coupe said in VicForests' own policy document to be an evaluation site for the "new" approach to clear-fell and seed tree retention, even the existing prescriptions let alone any refinements were not implemented. The coupe was completely clear-felled. Nothing was left standing over the entire 18.4 ha, and this was plain on the Court's view. Whatever aspirations for VicForests' forestry operations on the ground Mr Paul might have "moving forward", this coupe - said in fact to form part of VicForests' new approach to its forestry operations "moving forward" failed to even adhere to existing requirements.
1063 A further point can be made from the Greendale post-harvest map, in terms of how habitat prescriptions "on the ground" are implemented, or in this case not implemented. This concerns the Leadbeater's Possum SPZ prescription. To the south-west and south-east of Greendale, there are a number of 200 m SPZs. It will be recalled that Professor Woinarski's opinion is that these SPZs are, in any event, not especially effective, but they are a cornerstone of VicForests' response in this proceeding to allegations about significant impact from forestry operations on the Leadbeater's Possum. What is apparent is that a proportion of one of the SPZs has been clear-felled. There is a note on the post-harvest map which states: "area harvested before SPZ created". Dr Davey also makes this point in the table in his first report (at p 121), and estimates it is one-eighth of the coupe. There was no reliable evidence about the proportion. The evidence from the May 2019 Harvesting and Regeneration Systems document suggests Greendale was harvested in 2019. It was certainly very recent when the Court observed it on the view. The point is that according to the post-harvest map (and Dr Davey's report), the Leadbeater's Possum SPZ was created after harvesting, so also very recently and sometime in 2019, before the trial in this proceeding. Yet, it was created over land which had already been clear-felled. So, in reality, the SPZ did not contain the 200 m radius of forest for the Leadbeater's Possum habitat that it was supposed to. In reality, the colony around which it was created did not secure the benefit of the (inadequate) amount of forest supposed to be reserved. These sorts of disconformities are the kinds of matters which give the Court little confidence that even basic prescriptions (which the experts see, and I accept, as hardly adequate and of little effectiveness) are in fact implemented on the ground.
1064 A further issue about the effectiveness of any "new" silvicultural methods, and whether they are likely in fact to deliver better and improved protection to the Greater Glider, is the question of whether any additional forest retained under the proposed policies is likely to be preserved long enough for species such as the Greater Glider to derive habitat benefit from it, or simply for one logging rotation.
1065 The applicant contends that the Court should find retained patches (such as those Mr Paul indicated were retained additionally in Greendale as part of the "buffer" area) are permitted to be harvested under the new systems. It advances three reasons for this.
1066 First, in the Castella Quarry coupe, the applicant submits the "retained area" in that coupe was in fact designated for logging in that rotation (that is, within the next 80 years). This submission was made by reference to the coupe plan for the Castella Quarry coupe, which I discuss in more detail below. Essentially, as I understand it, the applicant contends that what it shows is a more than 7 ha hatched area which according to the legend is to be excluded from harvesting, but which has a silvicultural method from the May 2019 Harvesting and Regeneration Systems document attached to it ("Silv V"), signalling it will be harvested. The applicant contends this means that VicForests considers it permissible to harvest the retained areas under its new systems. Mr Paul did appear to confirm in his cross-examination that this area was likely to be harvested in the future:
Yes. What I'm putting to you is that the area that was marked set aside on this plan as habitat retention - sorry, 95 per cent, so the area not essentially to be in any way intensively forested, is poor timber - poor quality timber?---From my view of the site it's probably young timber. It's probably - it's - certainly being small it doesn't make useful timber at this stage. It may grow on one day and become timber into - decades into the future, but we don't just harvest timber because it's in front of us. If it's young and can be set aside to grow on, we will leave that to grow on.
Yes, and it's because of the nature, I suggest to you, of the timber that you've just described that it was determined that that section would not be the subject of any more intensive silviculture method than perhaps method 5, wasn't it?---That's certainly part of the decision, yes.
And I suggest to you that's what drove that decision rather than either the presence of habitat trees within that area or the recorded sightings of Greater Gliders within that area; that's correct, isn't it?---That - that would drive that decision, yes.
1067 Second, the applicant contends that none of the four iterations of the Harvesting and Regeneration Systems document before the Court included any specification of the period that retained areas must be protected, in contrast to VicForests' previous regrowth retention harvesting document which specified that retained areas must be protected for one rotation (nominally 80 years in Ash).
1068 In the table attached to its reply submissions, VicForests disputed these contentions. It submitted it was not apparent how the Castella Quarry coupe demonstrated what the applicant contends it does. I have explained what I find the document shows on its face, and this appears confirmed by Mr Paul's evidence.
1069 The third reason relied on Professor Baker's evidence in cross-examination, arising from comments he had made on some of the versions of VicForests' Harvesting and Regeneration Systems document. As I have noted earlier, Professor Baker was invited to, and did, annotate versions of this document with his opinions and suggestions. In cross-examination he was asked about an annotation that essentially put questions back to VicForests about the consequences for the timing of forestry operations from shifting to "multi cohort stands"; that is, stands of different aged trees. He had asked VicForests in his comment:
Are you planning to do multiple entries to make up for this? Are you planning on harvesting over larger areas to make up for this?
1070 In cross-examination he was asked to explain what he meant, and this was his evidence:
So the current silviculture, I think everyone here is well aware, is largely clearfell harvesting. So that is to say, you cut everything down within the context of the Code of Forest Practices, and you get an even-aged cohort. All the trees are roughly the same age. Okay. When you move to uneven-aged or multi-cohort forest silviculture as I refer to in here, you're leaving some trees. Now, there are - you know, the sort of extremes of this are you harvest all of the trees, and that's the clearfelling, or you harvest one tree in your forest, and that would be the ultimate sort of single tree selection system. In reality, we would be thinking about somewhere in the middle. Necessarily, if you harvest, say, 40 hectares in a coupe at one time, then you have - all of that wood is harvested then, and so the volume that's associated with that comes in. If you do something that is intermediate and you instead harvest, say, five one hectare patches, then you only have five hectares of wood, as it were, and so you can then -typically the way we would do multi-aged uneven-aged silviculture is that you would come back every 10, 15, 20 years. So that's what I referred to as multiple entries. Right. You wouldn't necessarily - or you certainly wouldn't if the hectare you harvested today, that would be left until, you know, 60, 70, 80 years. But the idea is that you come in with less intensive operations but you are doing them more frequently. That was the one question. And then the issue about harvesting of larger areas. If, instead of harvesting the whole 40 hectares at once, you're harvesting five hectares at once, then in terms of revenue, then I think it's a reasonable question given that they're a State-owned enterprise, to make sure that they understand that by shifting to that, then there will be a change in the revenues and then ask the question well, does that come from doing lighter silviculture over broader parts of the landscape. And again that might not be a bad thing in terms of, for example, Leadbeater's Possum habitat; the shelter woods, you know, look like they produce very nice big trees. But it has an impact, as it were, in terms of how much would you get from one place. Now, the reason, we sort of - as I said before, clearfelling is - the ecological basis for clearfelling is based on catastrophic fires or wind storms in other parts of the world. But the reality of is it's very efficient, right, so it's efficient to clearfell, and so when you do uneven-age silviculture in terms of revenue per unit area, you will harvest less and so you will have to come in more, so the costs tend to be higher.
1071 There was no evidence to which VicForests pointed in its submissions explaining how VicForests determines what is to occur, subsequently, with areas that are "retained" during a particular forestry operation. As the applicant submits, there is no definition of "retained" in the Code, the Management Standards and Procedures or the May 2019 Harvesting and Regeneration Systems document. There is a definition in the Code of "retained trees":
trees retained on a coupe during a timber harvesting operation because they are unmerchantable, are to serve as seed trees or wildlife habitat trees, or have been selected to grow on after thinning.
1072 The Code defines "thinning" as:
removal of part of a forest stand or crop, with the aims of increasing the growth rate and/or health of retained trees and, in commercial thinning, obtaining timber from trees that would otherwise eventually die before final harvest. Thinning is a type of tending.
1073 And "tending" in turn is defined as:
the treating of a forest stand to protect, maintain, or improve its stand health and/or timber production potential. Thinning and selective harvesting are types of tending.
1074 These definitions make it clear that areas with "retained trees" may well be subject to future harvesting. How "wildlife habitat trees" continue to be identified if contractors go back into an area - for example 5 or 10 years later - to harvest again, is not explained in the evidence so far as I can see. What permanent protection from forestry operations, if any, attaches to retained habitat trees is unclear (assuming they have otherwise survived forestry operations in a state so as to be useful to, and used by, the target species).
1075 Dr Smith's fourth report contains his assessment of VicForests' proposed silviculture systems and modified harvesting practices. At pp 5-6. his opinion is as follows:
I concluded from my review that the draft proposed changes in their present form are not sufficiently robust to be certain of bringing about any substantive improvement in the assessment and mitigation of timber harvesting impacts on the Greater Glider. I base this conclusion on many limitations of the proposed new adaptive management system including the following:
a) the proposed changes rely on the same pre-logging assessment procedures which have been shown to be unreliable and to miss 97% of Greater Glider habitat and populations;
b) proposed new silvicultural methods are so ill defined that they can be implemented in essentially the same manner (with the same adverse impacts) as current practice in Ash forests and are too ill-defined to be certain of preventing impacts in Mixed Species forests;
c) there are no proposed pre-and post-harvesting survey and monitoring requirements for the Greater Glider essential to provide baseline information for adaptive management;
d) there are no targets or thresholds to trigger changes to silvicultural methods in the event that Greater Glider numbers decline or fail to recover after harvesting;
e) proposed silvicultural methods are not sufficiently precautionary to ensure that local or regional extinctions do not occur before harvesting methods can be changed given the long time periods (40+ years) required to confirm Greater Glider recovery after initial post logging declines.
The proposed (HRS and HCV) policies on habitat tree retention represent little or no improvements over current inadequate practice. The HRS states that an FSC Controlled Wood evaluation audit "directed VicForests to increased focus on retaining and protecting hollow bearing trees, particularly where they exist outside the extent of designated old growth forest, i.e. small patches (less than three hectares) or scattered trees within coupes." VicForests approach to implementation of this directive is to state (HRS section 3.2) that they will "increase the retention and protection of hollow bearing trees, while also acknowledging the desirability of being able to factor broader landscape considerations, e.g. the extent to which hollow bearing trees are represented in the surrounding forest areas (across public land tenures)." VicForests states in its draft HCV Management Systems proposal that it will increase retention of habitat trees but this promise is highly conditional as any increase in habitat tree retention will take into account "the extent to which hollow bearing trees are represented in the surrounding forest areas, including other public land tenures comprising national parks, conservation reserves and informal reserves within State forests. In this way VicForests is seeking to achieve a balance between forestry and biodiversity across the forest areas in which it operates." This means that VicForests plans to do little or nothing to increase retention of hollow bearing trees within logged coupes and to rely largely on habitat tree retention in adjoining unlogged areas. This approach represents at best a continuation of current practice and at worst and acceleration of habitat tree loss in timber production forests.
1076 The doubts expressed by Dr Smith echoes some of the doubts I have formed on the evidence, in particular as between theory and practice in VicForests' forestry operations, and as between the imperative to secure sufficient timber from each coupe and VicForests' consequent reliance on there being adequate habitat in the reserve system. I also accept Dr Smith's opinion that the proposed methods, as set out in the policies, are not sufficiently well defined as to substantially differentiate them from the existing policies and methods. Finally, as Dr Smith observes, and Mr Paul confirmed, nothing in these policies - which are pitched at a general level - establishes any new methods specifically aimed to benefit the Greater Glider. While it might well be said that that is to be expected in a broad-based policy document aimed at VicForests' forestry operations across Victoria, the salient point is that the issue in this proceeding is how - if at all - VicForests' proposed new methods will render its planning and conduct of forestry operations compliant with cl 2.2.2.2 in relation to the Greater Glider. I see no basis to make a positive finding that they will.
