DEVIL'S STAIRCASE

Transcription

1 DEVIL'S STAIRCASE INVESTIGATION REPORT Investigation into VicForests' Compliance with Leadbeater's Possum (Gymnobelideus leadbeateri) Habitat Management Prescriptions Abstract VicForests scheduled and now active logging coupe was investigated to determine planning and operational compliance with the relevant instruments of the regulatory framework designed to provide minimum protection for the habitat of the endangered Leadbeater's Possum (LBP). The instruments assessed for compliance were the Central Highlands Forest Management Plan's Leadbeater's Possum Managaement Prescriptions and The Flora and Fauna Guarantee Act 1988 Action Statement for Leadbeater's Possum #062. The present investigation was undertaken in the context of an ongoing Victorian Supreme Court case, MyEnvironment Inc. v VicForest, whose judgment is currently in an appeal process. The subject matter is a debate over the very criteria to be used to asses forest planning and operational compliance with the LBP's management prescriptions. In addition, it is understood that the regulatory instruments themselves are to be reviewed and updated and may themselves be altered. As such, the results of this report are presented so as to be interpreted under various possible scenarios concerning the debated interpretations of and/or reviews of the relevant assessment criteria. This investigation concludes that VicForests have not complied with the relevant legislation and have breached their obligations under both the Central Highlands Forest Management Plan and the Flora and Fauna Guarantee Act (FFGA). The criteria for assessment used, methodology employed and the results of the investigation are detailed below. Surveyor/Author Andrew Lincoln Fauna and Flora Research Collective Inc.

3 Method Zone 1A 1 Hollow bearing trees ("HBT's") are the basis for the management prescriptions designed to provide some protection for the actual or potential habitat required by the Leadbeater's Possum. This investigation considers all HBT's (trees that contain hollows/cavities) encountered within the survey site that were of the species Eucalyptus regnans and likely to be considered as at least in the mature growth stage.2 The minimum size of tree containing hollows recorded in this investigation was a Eucalyptus regnans (Mountain Ash) having a Diameter at Breast Height ("DBH") of 1.43m. No trees smaller than 0.50m DBH were considered. The minimum height of the tree, whether it was dead or alive was 6.00m. All height measurements were estimates and records made were of minimum height estimations for each tree. Each eucalyptus tree encountered was first inspected for the presence of hollows using binoculars; estimated to be greater than 6.00m in height; measured at 1.30m above ground level around the trunk of the tree using a tape measure in order to measure the circumference and corresponding DBH measurement for each tree in order to ascertain that the tree under inspection was greater than 0.50m DBH. Every tree meeting these requirements was given a unique ID corresponding to the study site; assigned a "Waypoint" using a "Garmin GPSMAP 62s" GPS at an accuracy minimum of 10m+/- in the position format GDA 94,UTM UPS; inspected to determine its species; assessed as to the "form" of the tree corresponding to the methodology for "classification of forms of hollowbearing trees" of Lindenmayer et. al ; analysed as to the form of the hollows present on the tree; assesed against the tree growth stages schema of Jacobs (1955); the decorticating bark attached to the tree; the adjacent vegetation providing connectivity with the tree; marked with "flagging tape" containing its unique ID; and finally photographed at its base and upper branches. All of these details were noted and recorded on site. Investigations at the site begun along the coupe access road that has now been cleared into the area of forest comprising the scheduled coupe. From this point the forest was searched for HBT's following the methodology described above. As each HBT was inspected and recorded the forest was searched for further HBT's and advanced towards with the above process repeated for each. By noting the topographic and other site characteristics, compass bearing and GPS "waypoint" proximity data, the area delineated in the "Study Location" section of this report was investigated in this manner until all potential HBT's were investigated and recorded. Once the above process was completed the HBT location data recorded on site was later imputed into the "Garmin" GPS mapping program. Each HBT record was assessed against the varying criteria generative of management prescriptions under either the Central Highlands Forest Management Plan or the FFGA Action Statement #062 for the Leadbeater's Possum. Data from each HBT were imputed into separate spreadsheets depending on their relevance for meeting each of the management prescriptions, and the tables and corresponding maps presented in the results section of this report were generated. 1 Zone 1B investigations were not considered for this report. 2 Jacobs M.

19 Discussion Results 1 Flora and Fauna Guarantee Act - Action Statement for Leadbeater's Possum #062 ZONE 1A The first dot point for FFGA Zone 1A classification The "First criterion for inclusion" followed in this investigation requires that; "mature ash forest (>120 years old) and mixed aged ash forest where the oldest age class is mature (>120 years old)" be protected form logging by its inclusion in "Zone 1A Special Protection Zones" ("Zone 1A SPZ"). Additional criterion; "the minimum area for assessment and establishment of Zone 1A type forest shall be 3 hectares." - The data presented in Table 1. and Figure 1. indicate that the forest type within the area under investigation is mixed aged ash-eucalypt forest. - Within the 7.75 hectare area presented in Figure 1. there are 31 HBT's of varying size ranging from a Eucalyptus regnans indivdual at 1.43m DBH to a Eucalyptus regnans indivdual at 2.20m DBH and includes both living and dead as well as younger and older HBT's. - In Justice Osborne's Judgment in MyEnvironment Inc. vs VicForests in the Victorian Supreme Court 14 March 2012 His Honour at Paragraph 117 refers to "Smith and Lindenmayer, Tree Hollow Requirements of Leadbeater s Possum and Other Possums and Gliders in Timber Production Ash Forests of the Victorian Central Highlands (1988)"6 and in particular its reference to the "Ashton (1976)"7 publication of Eucalyptus regnans tree age as determined by DBH measurements accompanied by its corresponding caution: 8 - In 1975 Ashton, D. H. published the following table indicating a correlation between DBH measurements and age classification: 9 6 Smith and Lindenmayer, Tree Hollow Requirements of Leadbeater s Possum and Other Possums and Gliders in Timber Production Ash Forests of the Victorian Central Highlands (1988) 15 Australian Wildlife Research Ashton, D. H., "The Development of Even-aged Stands of Eucalyptus regnans F. Muell in Central Victoria", Australian Journal of Botany, 1976, 24, ibid., p Ashton, D. H., "The Root and Shoot Development of Eucalyptus regnans F. Muell", Australian Journal of Botany, 1975, 23, p. 868

20 - If the "criterion for inclusion" under consideration here is for "mixed aged ash forest where the oldest age class is mature (>120 years old)" then it must be considered whether the oldest age class within the study location is ">120 years old". - Of the 31 HBT's recorded at the study location 23 of these had a DBH greater than 1.5m and 3 of these with a DBH greater than 2.00m. - According to Ashton (1975) Eucalyptus regnans trees with a DBH between 1.50m and 2.50m are considered to be "" and between years old recorded HBT's under investigation are "" and within the age-class " years". - Using the equation indicating a relationship between DBH and age given in Ashton (1976), logy = 1.02 logx where y is the DBH (cm) and x the age in years10 the minimum age of trees considered under this criterion given a DBH of 1.43m is 130 years. - The oldest age class in this forest type is thus "mature (>120 years old)" and exists in an area greater than 3 hectares. - The study location indicated in Figure 1. and all possible polygons generated from the data in Table 1. must be included in the SPZ under this criterion. The second dot point for FFGA Zone 1A classification The "Second criterion for inclusion" followed in this investigation requires that; "regrowth ash forest with at least 12 live hollow bearing trees per 3 ha" be protected form logging by its inclusion in "Zone 1A Special Protection Zones" ("Zone 1A SPZ"). Additional criterion; "the minimum area for assessment and establishment of Zone 1A type forest shall be 3 hectares." - The data presented in Table 1. and in its corresponding Figure 1. within the yellow polygon displays an area of forest of 7.75 hectares present in and adjacent to the subject scheduled coupe and contains 31 living HBT's living HBT's over 7.75 hectares equates to a living HBT density 4 living-hbt's/ha which is that which is required under the present criterion (12 living-hbt's/3ha equating to 4 livinghbt's/ha). - At least 12 live hollow bearing trees per 3 ha exist within the study location for this criterion. - The area indicated in Figure 1. and all possible polygons >3ha generated from the data in Table 1. (excluding HBT - DSSTAG001) must be included in the SPZ under this criterion. 10 Ashton, D. H., "The Development of Even-aged Stands of Eucalyptus regnans F.

21 Results 1 and 2 Central Highlands Forest Management Plan - Leadbeater's Possum Management Prescriptions CH FMP ZONE 1A interpretation The "Third criterion for inclusion" followed in this investigation requires that; ">12 Living trees of the species Mountain Ash, Alpine Ash or Shining Gum containing hollows per 3 ha in patches greater than 3 ha" be protected form logging by its inclusion in "Zone 1A Special Protection Zones" ("Zone 1A SPZ"). Additional criterion; considered in this investigation is that each of the HBT's considered under this "Third criterion for inclusion" be "mature and/or senescent". - The data presented in Table 1. and Table 2. and their corresponding Figures 1a and 1b. and 2a. and 2b. display areas of forest of 7.75 and 5.75 hectares respectively (the yellow polygons ) that contains 31 and 23 living HBT's of the species Eucalyptus regnans respectively within and/or adjacent to the scheduled and active logging coupe under consideration in this report living Eucalyptus regnans HBT's over 7.75 hectares and 23 living Eucalyptus regnans HBT's over 5.75 hectares equate to respective densities of 4 living-eucalyptus regnans-hbt's/ha which is that which is required under the present criterion (>12 living-eucalyptus regnans-hbt's/3ha equating to 4 living-eucalyptus regnans-hbt's/ha). - As already explained in the "discussion section" of this report, Ashton (1975) and (1976) considers, with precaution, trees of DBH 1.50m to be "" of the 31 living-eucalyptus regnans-hbt's in Results 1. have DBH measurements 1.50m indicating that they are mature of the 23 living-eucalyptus regnans-hbt's in Results 2. have DBH measurements 1.50m indicating that they are mature. - The remaining living-eucalyptus regnans-hbt's included in each of the Results 1. and Results 2. sections of this report which are less than 1.50m DBH (to a minimum of 1.43m DBH) are addressed as follows: - In Justice Osborne's Judgment in MyEnvironment Inc. vs VicForests in the Victorian Supreme Court 14 March 2012 His Honour at Paragraph 246 addresses the complicated nature of characterising and identifying both "maturity" and "senescence": 246 It was submitted on behalf of MyEnvironment that the terms mature and senescing were so uncertain as to be meaningless. Whilst I accept that the evidence shows that a mature tree might be over 100 years old or might only be 90 years old, I do not accept this submission. It is apparent that the terms mature and senescing have a meaning well understood by foresters, which accords with that articulated by Jacobs in the 1955 publication to which the FMP itself refers.11 Further, they are terms deliberately adopted in the earlier section of the FMP which utilises them for the classification of forest stages. Mr Ryan reproduced in evidence Jacob s classification. The classification is based upon the form of the crown of the tree assessed. He explained that the illustration was originally prepared with respect to Blackbutt eucalyptus pilularis. I accept that the terms are capable of ready practical application on the ground. - Osborne J acknowledges that trees younger than those in the age class " years" designated by Ashton (1975) may be "mature" due to varying interpretations of "maturity" but that given the LBP habitat prescriptions are designed not for scientists but for foresters a general interpretation of 11 Mr Spencer s evidence is that in practice VicForests applies this standard conservatively and treats the standard as being met where there are 10 mature or senescing trees per 3 hectares.

22 maturity based on an even more subjective view of each HBT's "crown form" was favoured. - All of the 31 living-eucalyptus regnans-hbt's recorded were assessed against the schemtaic diagram of Jacobs (1955) and were found to conform to at least the third stage ( J3 ) which aims to represent (younger) trees. See the following diagram: - All of the 31 living-eucalyptus regnans-hbt's recorded are thus classified as mature'' (See Table 1. and Table 2. Further information recorded sections and Appendix A HBT photogrpahs for further detail). - An alternative interpretation of "maturity" could simply be the ability to reproduce sexually which would be readily identifiable by the presence of flowers, buds or fruit or an understating of the growth stage and/or age class when Eucalyptus trees become sexually mature. - All HBT's recorded in the course of this investigation had reached the stage of sexual maturity. - I. R. Ball et. al. in "A tree hollow dynamics simulation model"12 considers the questions of "maturity" and "senescing" with again another interpretation. - This paper defines any tree characterised as "Form 1" ("mature living tree with hollows")13 or above as "senescing" due to development in its degree of decay. "Form 0" in this report is the only growth stage that classifies trees as neither mature nor senescing. "Form 0" trees do not contain hollows. By implication all HBT's of any age class or DBH are prima facie considered to be both "mature and/or senescing". - All HBT's recorded in the course of this investigation are of "Form 1" or a greater form of senescence and under this interpretation are "mature and/or senescing". - In addition Ball et. al. reiterate precaution in the use of DBH measurements as an indicator of age class by stipulating that the sum published by Ashton (1976) (and republished in this report as "Y = 12 I.R. Ball et al., "A tree hollow dynamics simulation model", Forest Ecology and Management 123 (1999) ibid. p. 182

23 X1.02", where Y is the DBH and X the age in years) relates to the age class "before decay begins".14 - Using this equation, "Y = X1.02", where Y is the DBH(cm) and X the age in years 15, the minimum age of trees considered under this criterion given a DBH of 1.43m is 130 years. - All 31 living Eucalytpus regnans HBT's with a DBH greater than 1.50m or that conform to J3 (or greater) of Jacobs (1955) as displayed in Table 1. and Table. 2. and mapped in Figures 1a and b and Figures 2a and b. are of the requisite "Mountain Ash" species and meet one or more of the preceding interpretations of "maturity and/or senescence" and are arranged in a configuration of >4 HBT's per 3ha over an area >3ha. - The areas indicated in Figures 1a and b and Figures 2a and b. and all possible polygons >3ha generated from the data in Table 1. and Table 2. must be included in the SPZ under this criterion. Results 3 Central Highlands Forest Management Plan - Leadbeater's Possum Management Prescriptions CH FMP ZONE 1A interpretation The "Third criterion for inclusion" followed in this investigation requires that; ">12 Living trees of the species Mountain Ash, Alpine Ash or Shining Gum containing hollows per 3 ha in patches greater than 3 ha" be protected form logging by its inclusion in "Zone 1A Special Protection Zones" ("Zone 1A SPZ"). Additional criterion; considered in this investigation is that each of the HBT's considered under this "Third criterion for inclusion" be "mature and/or senescent". - The data presented in Table 3. and its corresponding Figures 3a and 3b. display an area of forest of 3.1 hectares (the yellow polygon) that contains 13 living HBT's of the species Eucalyptus regnans within the scheduled and active logging coupe under consideration in this report living Eucalyptus regnans HBT's over 3.1 hectares equates to a density > 4.19 livingeucalyptus regnans-hbt's/ha which is that which is required under the present criterion (>12 living-eucalyptus regnans-hbt's/3ha equating to 4.19 living-eucalyptus regnans-hbt's/ha). - Each of the living Eucalyptus regnans HBT's within these polygons have DBH measurements equal to or greater than 1.50m and conform to J3 (or greater) of Jacobs (1955). - All the 13 living Eucalytpus regnans HBT's with a DBH greater than 1.50m as displayed in Table 3. and mapped in Figures 3a-b. are of the requisite "Mountain Ash" species and meet one or more of the preceding interpretations of "maturity and/or senescence" (see this report's ''Results 1 and 2'' section) and are arranged in a configuration of >4.19 HBT's per 3ha over an area >3ha. - The area indicated in Figure 3a-b. and all possible polygons >3ha generated from the data in Table 3. must be included in the SPZ under this criterion. 14 ibid. p ibid. p. 182 Figure D: The following image shows 13 of the 53 HBT's recorded within this investigation.

Additional criterion; considered in this investigation is that each of the HBT's considered under this "Third criterion for inclusion" be "mature and/or senescent". - The data presented in Table 4. and its corresponding Figures 4a and 4b. display an area of forest of 3.1 hectares (the yellow polygon) that contains 13 living HBT's of the species Eucalyptus regnans within the scheduled and active logging coupe under consideration in this report living Eucalyptus regnans HBT's over 3.1 hectares equates to a density > 4.19 livingeucalyptus regnans-hbt's/ha which is that which is required under the present criterion (>12 living-eucalyptus regnans-hbt's/3ha equating to 4.19 living-eucalyptus regnans-hbt's/ha). - Each of the living Eucalyptus regnans HBT's within these polygons have DBH measurements equal to or greater than 1.50m and conform to J3 (or greater) of Jacobs (1955). - All the 13 living Eucalytpus regnans HBT's with a DBH greater than 1.50m as displayed in Table 4. and mapped in Figures 4a-b. are of the requisite "Mountain Ash" species and meet one or more of the preceding interpretations of "maturity and/or senescence" (see this report's ''Results 1 and 2'' section) and are arranged in a configuration of >4.19 HBT's per 3ha over an area >3ha. - The area indicated in Figure 4a-b. and all possible polygons >3ha generated from the data in Table 4. must be included in the SPZ under this criterion.

25 Conclusions The "results" and "discussion" sections of this report demonstrate that VicForests employees and contractors in scheduled and now active logging coupe plan to log and have commenced operations in areas required under both the "Central Highlands Forest Management Plan's Leadbeater's Possum Managaement Prescriptions" and the "Flora and Fauna Guarantee Act's Action Statement for Leadbeater's Possum #062" to be protected from logging by their inclusion in "Special Protection Zone" reserves. In summary, these conclusions are drawn from the following; Flora and Fauna Guarantee Act - Action Statement for Leadbeater's Possum #062 ZONE 1A The first dot point - The oldest age class in the study location is "mature (>120 years old)" and exists in an area greater than 3 hectares. - The study location indicated in Figure 1. and all possible polygons generated from the data in Table 1. must be included in the SPZ under this criterion. The second dot point - At least 12 live hollow bearing trees per 3 ha exist within the study location for this criterion. - The area indicated in Figure 1. and all possible polygons >3ha generated from the data in Table 1. must be included in the SPZ under this criterion, and; Central Highlands Forest Management Plan - Leadbeater's Possum Management Prescriptions ZONE 1A - All 31 living Eucalytpus regnans HBT's with a DBH greater than 1.50m and/or conforming to the mature classification of Jacobs (1955) as displayed in Table 1. through to Table 4. and mapped in Figures 1.a and b. through to Figure 4. a and b. are of the requisite "Mountain Ash" species and meet one or more of the preceding interpretations of "maturity and/or senescence" and are arranged in a configuration of 4 HBT's per 3ha over an area >3ha. - The area indicated in Figures 1. a and b. through to Figures 4. a and b. and all possible polygons >3ha generated from the data in Table 1. through to Table 4. must be included in the SPZ under this criterion, thus; The Department of Sustainability and Environment (DSE) as the regulatory body governing forestry operations in Victorian State Forest must act to hold the responsible bodies accountable for such breaches and restrain VicForests employees and contractors from further breaching the regulatory framework. In order that further breaches do not occur the DSE must ensure that VicForests employees and contractors do not log or plan to log any areas that must be set aside for the conservation of the endangered Leadbeater's Possum (Gymnobelideus leadbeateri).
