1. INTRODUCTION

1.1 Background The Western Australian Department of Health (DoH) is currently redeveloping the existing Busselton Hospital site to accommodate the expansion of Busselton and greater Busselton region including Dunsborough.

Approval was granted by the Department of Environment and Conservation (DEC), under a Native Vegetation Clearing Permit (CPS 4433/1), to clear a total of 238 trees, of which no more than 156 Peppermint (Agonis flexuosa) trees may be cleared (Coffey Environments, 2012b). Approval was also granted from the Commonwealth Department of Sustainability, Environment, Water, Population and Communities (SEWPaC), under an Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) referral (EPBC 2011/6011) to clear 156 Peppermint trees. Native vegetation clearing required as part of the hospital redevelopment project occurred during 4 to 14 September 2012.

The Busselton Hospital site is 12.3 hectares (ha) of which a large proportion is open Peppermint (Agonis flexuosa) woodland, with relatively little understorey. The site is located in the core habitat of the Western Ringtail Possum (WRP) (Pseudocheirus occidentalis), which is listed as a threatened species under both State (Wildlife Conservation Act 1950) and Federal (EPBC Act) environmental legislation.

Coffey Environments was commissioned to undertake a tree health assessment of the site and to provide advice regarding the WRP habitat and possible linkage corridors to other areas of WRP habitat. Advice on WRP habitat and linkage corridors was provided in Coffey Environments (2011a) and tree health assessments were undertaken prior to clearing in September/October 2010, March 2011, September/October 2011 and March 2012 (Coffey Environments 2011a, 2011b and 2012a). The results of these assessments constitute baseline environmental data for the site after the winter (high rainfall) period of September and following summer (low rainfall or drought) period of March.

This report details the results of the October 2012 tree health monitoring. To assist with the tree health assessment, Coffey Environments commissioned SpecTerra Services to provide Digital Multi-Spectral Imagery (DMSI) of the Busselton Hospital site and the immediate surrounds. The DMSI is used to monitor changes in vegetation condition using light band wave-lengths.

The results from the October 2012 tree health monitoring period will be compared to previous monitoring conducted in September 2010 and September 2011 to determine whether the trees are improving or declining in health prior to the redevelopment of the site. The October 2012 tree health monitoring does not include the Peppermint trees removed in September 2012 as part of the commencement of redevelopment works. Of the trees that were removed 60 trees had been tagged and undergone assessment during previous assessment periods.

1.2 Tree Clearing Activities Native vegetation clearing activities approved under the Native Vegetation Clearing Permit (CPS 4433/1) occurred during 4 to 14 September 2012. Under CPS 4433/1 the DoH had approval to clear 238 trees, of which no more than 156 were allowed to be Peppermint trees.

During the clearing activities 200 trees were cleared, which included 153 Peppermint trees. The majority of the cleared trees were located in the south-east corner of the hospital site.

Of the 153 Peppermint trees cleared in September 2012, 60 were trees that had been monitored by Coffey Environments as part of the tree health monitoring program.

1.3 Scope of Works The scope of works for the tree health assessment addressed in this report includes:

• September 2012 survey of tree health monitoring using digital aerial imaging (DMSI).

• October 2012 survey of tree health using on-ground surveys.

• Comparison between the September 2010, September 2011 and October 2012 tree health assessments.

• Inclusion of recommendations to manage and maintain the health of trees located at the Busselton hospital site.

1.3 Previous Assessments A number of technical assessments have been conducted for the Busselton Hospital site, that are directly relevant to this report including:

• A technical evaluation of sites for the Busselton Hospital redevelopment (SKM, 2006).

• An assessment of tree canopy cover (SurvCon Pty Ltd, 2009 – unpublished data).

• Tree Health and Western Ringtail Possum Habitat Assessment, Busselton Hospital Site March 2011 (Coffey Environments, 2011a).

• Tree Health Monitoring Busselton Hospital Site September 2011/October 2011 (Coffey Environments 2011b).

• Tree Health Monitoring Busselton Hospital Site March 2012 (Coffey Environments 2012a).

• A significant fauna and flora values report (Coffey Environments, 2009).

• Targeted Western Ringtail Possum surveys in November 2009, February 2010, December 2010, March 2011, November 2011 and March 2012 (Correspondence dated 20 November 2009, 10 February 2010, 11 January 2011, 14 March 2011, 17 November 2011 and 8 March 2012 respectively).

2. BACKGROUND INFORMATION

2.1 Location and Land Use Busselton Hospital is located at 203 Bussell Hwy, West Busselton (Figure 1). Busselton is located approximately 200 km south-west of the Perth Central Business District. The site is bounded by Bussell Highway to the south, Craig Street and private properties to the west, Mill Road to the east and a Foreshore Reserve and Geographe Bay to the north (Figure 2).

Currently the site supports the existing Busselton Hospital and associated infrastructure, the St Johns Ambulance depot and the Kevin Cullen Community Health Centre. The site also supports remnant native vegetation located around the perimeter of the site. The native vegetation is described as open woodland of Agonis flexuosa (Peppermint) with a disturbed understorey (SKM, 2006).

2.2 Climate The climate of the Busselton region is described as Mediterranean with warm, dry summers and cool, wet winters (Beard, 1990). A Bureau of Meteorology (BOM) weather station was located on the Busselton Hospital Site (Weather Station 09569) however; this station was closed on 23 November 2011. This weather station was operational from 1998 to November 2011, collecting both temperature and rainfall data. A second BOM weather station (No. 09515) was included as a comparison for longer-term regional data. This weather station is located approximately 2.5 km east-southeast from the site near the Shire of Busselton administration offices. This particular weather station has been operational since 1877 and therefore provides a suitable long-term comparison to the Busselton Hospital site. However, the station ceased collecting temperature data in 1975. Weather Station 09603 (Busselton Aerodrome) was opened in 1997 and this weather station records the current temperature data closest to the site.

Busselton receives the majority of rainfall during the winter months of June, July and August (BOM, 2012) with an annual total between 635 mm (Station 09603) and 663.5 mm (Station 09515). During the hottest three months (January, February and March) of the year the temperature ranges from a minimum of 15.4°C to a maximum of 32.7°C (Station 09603). During the coldest three months (June, July and August) of the year the temperature ranges from a minimum of 4.6°C to a maximum of 18.0°C (Station 09603) (BOM, 2012).

2.3 Vegetation The Busselton Hospital site is located within the Geographe Bay Quindalup Dune Plant Community of the Quindalup Dunes Vegetation Complex (Webb et al., 2009). Around 987 ha of the Quindalup Dunes remains vegetated on the Busselton Plain, however, this includes vegetation considered to be Degraded and Completely Degraded. It is estimated that potentially only 20% of the Quindalup Dune vegetation within the Busselton Plain is in Good or better condition.

Currently, there is greater than 30% of the Quindalup Dunes Vegetation Complex remaining on the Busselton Plain, however, as stated above only 20% is considered to be in Good or better condition. Within the Shire of Busselton, approximately 25% of the pre-European extent of the Quindalup Dunes Vegetation Complex remains vegetated (Molloy et al., 2007).



4

The vegetation is representative of the Geographe Bay Quindalup Dune plant community and is considered to be regionally significant as this community does not meet the minimum nationally recommended levels of retention (30% extent remaining of pre-European vegetation complexes) (EPA, 2006). The National Objectives and Targets for Biodiversity Conservation 2001-2005 recognises that a retention of 30% or more of the pre-clearing extent of each ecological community is necessary if Australia’s biological diversity is to be protected (ANZECC, 2000). The EPA has adopted this level of retention within Position Statement No. 2 (EPA, 2000) and Guidance Statement No. 10 (EPA, 2006).

The hospital site supports remnant native vegetation, namely, low woodland of Peppermint (Agonis flexuosa) over Coastal Sword-sedge (Lepidosperma gladiatum) in the north of the site adjacent to the coast and introduced grasses in the south of the site.

Following a site visit and survey, Coffey Environments’ determined the condition of the vegetation to be Good to Degraded based on the vegetation condition rating scale developed by Keighery (1994) and published within the Bush Forever Strategy (Government of Western Australia, 2000). The condition of the vegetation was considered to be Good to Degraded because of the lack of native understorey species over the majority of the site, the high prevalence of introduced flora species and the presence of several informal vehicle tracks. Keighery’s condition rating scale ranges from Pristine (where the vegetation exhibits no visible signs of disturbance) to Completely Degraded (where the vegetation structure is no longer intact and without native plant species). Table 1 below provides a description of each of the vegetation condition rating scales.

Table 1 Vegetation condition rating scale

Rating Description Pristine Pristine or nearly so, no obvious signs of disturbance.

Excellent Vegetation structure intact, disturbance affecting individual species and weeds are nonaggressive species.

Very Good Vegetation structure altered obvious signs of disturbance. For example, disturbance to vegetation structure caused by repeated fires, the presence of some more aggressive weeds, dieback, logging and grazing.

Good

Vegetation structure significantly altered by very obvious signs of multiple disturbances. Retains basic vegetation structure or ability to regenerate. For example, disturbance to vegetation structure caused by very frequent fires, the presence of some very aggressive weeds at high density, partial clearing, dieback and grazing.

Degraded

Basic vegetation structure severely impacted by disturbance. Scope for regeneration but not to a state approaching good condition without intensive management. For example, disturbance to vegetation structure caused by very frequent fires, the presence of very aggressive weeds, partial clearing, dieback and grazing.

Completely Degraded

The structure of the vegetation is no longer intact and the area is completely or almost completely without native species. These areas are often referred to as parkland cleared with the flora composing weed or crop species with isolated native trees or shrubs.

2.4 Digital Multi-Spectral Imagery SpecTerra Services provide airborne remote sensing imagery for vegetation mapping and monitoring projects. SpecTerra were commissioned to provide a Digital Multi-Spectral Imagery (DMSI) of the hospital site and surrounds to provide accurate imagery of the health of the vegetation. The initial fly-over is considered to be baseline and further subsequent flights allow comparisons to be made between the fly-overs. SpecTerra refer to this as ‘change detection’. The



5

technique can be used to determine whether the vegetation is improving or declining based on Plant Cell Density (PCD) values (Infrared Reflectance/Red Reflectance).

The PCD is sensitive to the quantity of leaves in each pixel (sample) and the density of healthy plant cells in those leaves. The Red band (675 nm) is positioned at maximum absorption by leaf chlorophyll content and the Infrared band where the leaf structure of healthy plants strongly reflects incoming energy.

3. METHODOLOGY

3.1 On-Ground Tree Health Assessment Methodology selected to undertake the on-ground assessment of tree health was designed to ensure accurate, scientific data was collected that could be used for statistical analysis of the site and for comparison with additional sites located in the greater Busselton region.

The following documents were reviewed to assist with the development of the methodology to assess the health of the trees located within the site.

• Schomaker et al. (2007) Crown-Condition Classification: A Guide to Data Collection and Analysis.

• McDonald et al. (1990) Australian Soil and Land Survey: Field Handbook (Second Edition).

• Coffey Environments (2010) Tree Health Monitoring, Provence Public Open Space, October 2009 Monitoring Period.

The methodology involved the establishment of four transects of 100 m in length (Figure 3) and the tagging of 152 individual trees within the site (112 in September 2010 and a further 40 in March 2011). Every tree along the transect and 5 m either side of the transect centreline was also tagged. This equated to a total of 290 trees tagged throughout the site (Figure 4; Appendix A). The tags were attached with wire loosely wound around the tree in a way which would not hinder future growth and girth expansion of the tree.

In September 2012, 60 of the 290 tagged trees were removed as part of the redevelopment of the site. Subsequently, tree numbers 139 - 142, 145, 151 - 174, 179 - 182, 185, 186, 189 - 203, 213, 278 and 283 - 290 were not recorded during the October 2012 survey. These tree numbers have been removed from this survey and will be removed from future tree health surveys and will no longer be recorded. The removal of the 60 tagged trees will not affect the survey design or analysis of results. The analysis of results will be based on 230 tagged trees located across the site. A total of 230 trees were monitored and assessed for tree health in the October 2012 survey.

Previous tree health monitoring surveys were undertaken on 21 to 22 September 2010, 24 to 25 March 2011, 21 to 22 September 2011 and 22 and 23 March 2012. These results constitute baseline information for the post winter (high rainfall) period of September and the post summer (low rainfall or drought) period of March. The October 2012 tree health survey was undertaken on 15 and 16 October 2012, which is, approximately a month following the previous spring survey undertaken in September 2011. Information relating to the previous tree health assessment undertaken at the site is located in the March 2012 report (Coffey Environments, 2012a).

The four transects were established within areas of dense canopy growth in the north of the site and the south-west corner. Posts were left in the ground at 10m intervals with photos initially taken from each post in September 2010 and March 2011. Photos were also taken from the north side of every individual tree, where practicable. These photos may or may not be used in determining the health of the tagged trees.

The following information was collected from each tagged tree within the site:

• Estimated height – The height of each tagged tree was estimated visually to the nearest half metre (i.e. the nearest 0.5 m).



8

• Number of trunks – The number of trunks originating from the base of the tree was counted. This value can be fairly arbitrary with the possibility of two or more trees being considered to be one tree.

• Crown Position – The position of the crown was estimated based on the height of the tree and is considered to be a function of the individual live crown in relation to the surrounding overstorey. Tree height between 2.5 m and 7 m was considered to have a Lower Crown Position; tree height between 7.5m and 8.5 m was considered to have a Middle Crown Position; and tree height exceeding 9 m was considered to have an Upper Crown Position.

• Diameter at Breast Height (DBH) – A DBH tape was passed around the trunk of the tree with the value recorded. In the instance of a tree having several trunks, the trunk the tag has been attached to was sampled.

• Vigour – A visual assessment of the crown vigour of individual trees classified into three categories. Vigour Class 1 are trees that are considered to have a healthy percentage of live canopy, generally >35% and Vigour Class 3 are trees that are considered to have a very poor-degraded percentage of live canopy, generally <20%. Vigour Class 2 are trees that are considered to be somewhere between healthy and unhealthy, generally having >20% or <35% of live crown. The Vigour Class ratings ranged from 1 (for a healthy tree) through to 3 (for unhealthy, dying or dead trees) with a rating of 1.5 or 2.5 used for trees considered to be in between either 1 and 2 or 2 and 3.

• Crown Density – Is an estimate of the proportion of the crown volume that contains biomass (i.e. green foliage, branches and reproductive structures) compared to if the entire canopy was well vegetated (i.e. 100%). Crown density is recorded as a percentage.

• Foliage Transparency – Is an estimate of the absence of foliage where foliage would normally occur. Foliage transparency is directly related to Crown Density. Foliage Transparency is recorded as a percentage.

• Crown Dieback – Is a measure of the proportion of the crown that has experienced recent dieback from branchlets and canopy branches. Crown Dieback has been recorded into one of seven categories based on a percentage of crown dieback. The categories are:

– 0–5% = Category 1. – 6–10% = Category 2. – 11–20% = Category 3. – 21–40% = Category 4. – 41–60% = Category 5. – 61–80% = Category 6. – 81–100% = Category 7.

• General Tree Observations – The following observations of each tagged tree were also recorded. These observations do not generally suggest a tree is in decline.

– Insect Damage – Notes were taken from each tagged tree on obvious signs of insect damage (i.e. damage from borers). Generally trees are able to cope with some form of insect activity and trees provide a niche for many insect species (i.e. spiders etc).

– Pathogens – Notes were taken from each tagged tree if obvious signs of pathogens were evident (i.e., cankers, fruiting bodies).



9

– Epicormic Growth – Notes were taken from each tagged tree if epicormic growth was seen. Epicormic growth is a response to stress (i.e., fire) and new shoots are produced from epicormic buds.

– Flowering and/or Fruiting – Notes were taken from each tagged tree if the tree was flowering or had new fruits.

– Presence of Possums or Dreys – Notes were taken from each tagged tree if a possum was sighted in the tree (asleep in the tree during the day) or a possum drey was recorded from the tree.

3.2 Digital Multi-Spectral Imagery SpecTerra have completed five flights over the Busselton hospital site to capture the Plant Cell Density (PCD) of the trees located within the site. The flight details are provided below in Table 2. The imageries were taken at four band lengths ranging from Blue (450 nm) to Near Infra-red (780 nm) with additional Green (550 nm) and Red (675 nm) Band lengths. PCD is strongly related to both leaf biomass and leaf area index.

The imagery provided by SpecTerra, with the True and False colour imageries, for the September 2012 fly-over is provided in Appendix B. For comparison, the imagery for the October 2011 fly-over is provided in Appendix C.

The October 2011 and September 2012 PCDs will be compared to provide meaningful ‘change detection’ between two comparative seasons. SpecTerra have also provided the PCD change detection data of the site for the period October 2010 to September 2012 to determine whether there was a meaningful change since the initial assessment.

Details regarding the results of the March 2011 flight and March 2012 flight are reported in Coffey Environments 2012a.

4. RESULTS The October 2012 data collected from the 138 tagged trees located along the four transects and the 92 individually tagged trees are provided in Appendices D1 to D5. The September 2011 data is provided in Appendices E1 to E5.

4.1 Climate Climate data from Station 09515 (Busselton Shire) indicates the 2012 winter period was slightly wetter than in previous years (350.9 mm) when compared to the 2011 winter period (309.6 mm) (Table 3) (BoM, 2012). A large rainfall event was recorded in June 2012 at this station when 214.1 mm of rain was recorded.

Climate data from Station 09603 (Busselton Aerodrome) indicates the 2012 winter period was also slightly wetter than in previous years (303.2 mm). In winter 2011, 260 mm of rainfall was recorded at station 09603 (Table 3). In June 2012, this station received a large amount of rainfall when 171.0 mm was recorded (Table 3) (BoM, 2012).

Chart 1 provides a comparison between monthly average and monthly rainfall total at Weather Stations 09515 and 09569 from January 2010 to October 2012. Station 09515 provides long term data for the Busselton region. No further rainfall data is provided for Station 09596 following August 2011 due to the closure of this station on 23 November 2011 (Chart 1).

Chart 2 shows actual monthly temperatures and mean monthly temperatures (minima and maxima) recorded from June 2010 to August 2012, displaying data from both the Busselton hospital site and the Busselton Aerodrome (from December 2011 to August 2012). Temperature data for Station 09569 (Busselton hospital) is provided for the period June 2010 to November 2011 (Chart 2). December 2011 to August 2012 data is provided for Station 09603 (Busselton Aerodrome) (BoM, 2012).

Mean monthly maximum temperatures were lower than actual maximum temperatures for the period June 2010 – November 2011 for Station 09569 (Chart 2). Actual monthly minimum temperatures for Station 09569 were higher in November 2010 to April 2011 than the monthly minimum temperatures for the same period. June 2011 to August 2011 and October 2011 to November 2011 recorded higher actual monthly minimum temperatures in comparison to mean monthly minimum temperatures for the same period (BoM, 2012).

Overall, actual monthly maximum temperatures for Station 09603 were higher than the mean monthly maximum temperatures for the period December 2011 to August 2012. The exception was in February 2012, when recorded temperatures were lower than the mean monthly maximum (Chart 2).

Actual monthly minimum temperatures at Station 09603 were higher in December 2011 to February 2012 when compared to average monthly minimum temperatures recorded for the same period. Actual minimum monthly temperatures for April and June 2012 were also higher than mean monthly minimum temperatures for the same months (BoM, 2012).

The weather during the tree health monitoring was described as fine and warm with minimal cloud cover. The maximum temperatures were 21.3ºC and 20.6ºC on 15 and 16 October 2012 when the tree health assessment was undertaken (BoM, 2012).

4.2 Tree Species Agonis flexuosa, Melaleuca sp. and Eucalyptus sp., were recorded and tagged from within the hospital site. Only one Eucalyptus sp. and two Melaleuca sp. were tagged, the remaining 287 trees originally tagged were Agonis flexuosa. The Eucalyptus and Melaleuca species are cultivars (i.e. nursery or horticulture varieties) that have either been planted or have escaped from nearby areas.

All tree species 5m either side of the transect centreline were tagged. Only Peppermint trees were tagged for the individual trees over the site due to importance of Peppermint as a habitat for the WRP. Peppermint trees comprise greater than 90% of the 4.092 ha of canopy tree cover recorded from the site (SurvCon Pty Ltd – unpublished data).

4.3 Vigour The mean combined vigour class of 1.86 was recorded from tagged trees at the site during the October 2012 assessment (Table 4). The results show the majority of tagged trees have a live canopy greater than 20% or less than 35%. Mean tree vigour varies at the site from healthy to unhealthy trees. A slight increase in the mean combined vigour class was recorded in October 2012 when compared to the previous monitoring undertaken in March 2012 (1.80). The increase in the value of the tree vigour class indicates a reduction in the percentage of live tree canopy and therefore a decline in tree health. The decline is evident when compared to the mean combined vigour class recorded for the same period in September 2011 of 1.57. The majority of trees assessed during the spring 2010 period had a healthy percentage (>35%) of live tree canopy. With the exception of September 2011 when a slight improvement in crown vigour was observed, overall, the mean combined vigour class has increased resulting in a consistent decline in the health of trees at the site throughout the 2010 to 2012 monitoring period.

The mean vigour class ratings for all trees including trees from transects 1, 2, 3, 4 and individual tagged trees recorded from the September 2010, September 2011 and October 2012 tree health assessments are provided in Table 5. The table also shows the frequency of vigour classes over the three spring assessments during 2010, 2011 and 2012.

In October 2012, the majority of trees were identified to be of vigour class 1.5 (80 trees) and vigour class 2 (68 trees). In September 2011, the majority of trees were also identified to be in vigour classes 1.5 and 2. However, the majority of trees in the 2011 period were assessed in vigour class 1.5 (115 trees). In September 2010 the majority of trees were assessed in vigour class 1 (111 trees) and vigour class 1.5 (79 trees) (Table 5).

Table 5 also shows an increase in the number of trees assessed in vigour class 2.5 in October 2012 when compared to previous years during the same period. Overall, a decline is evident in the crown vigour of trees at the site from when the initial monitoring was undertaken in September 2010.

Tables 6 compares the mean vigour class ratings recorded for all trees from the September 2010, September 2011 and October 2012 tree health assessments. The mean vigour class for transects 1 to 4, individual trees and combined (all tree data) are also depicted in Table 6 for this period.

A considerable increase in the mean vigour class ratings from the initial spring 2010 tree health assessment is evident for all four transects and the individually tagged trees as shown in Table 6. These results indicate an overall decline in the crown vigour and tree health of the majority of trees at the site. Transect 3 was the only transect that showed a slight decrease in the mean vigour class (1.83) in spring 2012 when compared to spring 2011 (1.85).

The total number of tagged trees at the site was reduced from 290 in 2010 and 2011 to 230 trees in 2012. The removal of these 60 trees has had little impact on tree health results undertaken in spring 2012.

4.4 Crown Density and Foliage Transparency Mean crown density across all transects and individual trees decreased by 1.87% in October 2012 when compared to the September 2011 results (Table 7). Trees at the site have shown a decrease in mean crown density by 5.54% since the initial spring monitoring was completed in 2010. The decrease in mean crown density demonstrates a reduction in crown volume and a decline in tree health.

Mean foliage transparency increased to 75.43% in October 2012. The results show a slight increase in mean foliage transparency of 1.85% when compared to the assessment completed in September 2011 (73.58%) (Table 7). These results depicted in Table 7 indicate a reduction in crown volume and an increase in the absence of foliage, both of which indicate a decline in tree health at the site (Table 7).

Table 8 shows a comparison of the mean crown density and mean foliage transparency values for the September 2011 and the October 2012 tree health assessments. Mean crown density decreased throughout all transects, individual trees and combined tree results when compared to the September 2011 assessment (Table 8). The crown density ranges were similar in both spring assessments. Transect 4 recorded the lowest mean crown density (22.20) in October 2012 which was a similar result to the previous year (23.80) (Table 8).

Mean foliage transparency increased in October 2012 when compared to the previous spring assessment. Transect 3 showed an increase in the range of foliage transparency values (55% - 100%). The majority of foliage transparency range values were similar to the previous spring assessment. As expected, the highest mean foliage transparency values were recorded in Transect 4 indicating these trees were in the poorest condition at the site. These results illustrate a decline in tree health in the majority of trees located at the site.

4.5 Crown Dieback Tables 9 and 10 show the comparisons between crown dieback categories across the four transects, the 112 individual trees and combined data between September 2010, September 2011 and October 2012. The frequency of crown dieback categories using combined data (all tree data) from tree health assessments completed in spring and autumn 2010 – 2012 is presented in Chart 3. The monitoring undertaken in October 2012 identified evidence of crown dieback in all of the tagged trees at the site and an increase in crown dieback when compared to the initial monitoring completed in September 2010 (Table 9 and Table 10).



18

Chart 3 Frequency of crown dieback categories from September 2010 to October 2012

The majority of trees assessed for crown dieback in spring 2012 were classified in category 2 (76 trees) and contained 6% – 10% of crown dieback. Category 3 (11% – 20% of crown dieback) recorded the second largest number of trees (60 trees) during monitoring of the site. When compared to the previous spring assessment in 2011, the majority of trees were classified into categories 1 and 2, indicating trees had less crown dieback in 2011. In spring 2010, the majority of trees (125 trees) were classified into category 1 and contained 0% – 5% of crown dieback. The large number of trees (50%) classified in this category in 2010 represent healthy trees with very little crown dieback (Table 9).The results of the three assessments indicate an increase in the number of trees with crown dieback at the site (Table 9 and Table 10).

In contrast to the spring 2011 assessment, a decrease in the number of trees in categories 5, 6 and 7 is evident when compared to the spring 2012 assessment (Chart 3 and Table 10). The variability in these results may be due to the removal of 60 trees at the site in September 2012. However, when the spring 2012 assessment is compared to earlier monitoring undertaken for the same season in 2010, there is an increase in the number of trees in these same categories (Chart 3, Table 9 and Table 10). These results also indicate an increase in crown dieback in trees over a two year period and a decline in tree health at the site (Chart 3).

Transects 2 and 4 recorded an increase in the number of trees with crown dieback in category 7, classified as 81% – 100% when compared to the previous assessment undertaken in the same season in 2011 (Table 10). Transect 2 also recorded a large increase in crown dieback in category 3 (11% – 20% of crown dieback) with 48% (15 trees) identified. Transect 3 recorded the largest increase of 52% in the number of trees with crown dieback in category 2 (6% – 10% crown dieback) in spring 2012.

4.6 General Tree Observations 4.6.1 Insect Damage As in previous years, many of the tagged trees showed the presence of insects. The October 2012 assessment identified 74 trees (32% of trees) with insects present. Borers were observed in 10 (4% of trees) of these trees. Termites were also observed in 15 trees (6.5% of trees) at the site during the assessment. A decrease in the percentage of borers was observed when compared to the previous spring assessment completed in 2011 (18%). A decrease in the percentage of termites of 8% was also observed when compared to the previous spring assessment.

The decrease in the number of trees showing insect damage may be the result of the clearing of 60 trees in September 2012. Many of the trees that were removed showed the presence of insects. Observations of insect damage were also general and opportunistic rather than targeted searches.

4.6.2 Pathogen Damage None of the trees identified as affected by pathogens during previous assessments presented evidence of pathogen infection at the time of the October 2012 assessment. Observations on pathogen damage are of a general nature, and presence may only be identifiable after laboratory tests or when pathogens have fruiting bodies (fungi) present.

4.6.3 Tree Deaths In October 2012, one tree, Agonis flexuosa (Tree No. 108) had died since the previous monitoring was undertaken in March 2012. A number of trees at the site showed a decline in tree health and this was evident from a decline in tree vigour, an increase in crown dieback, or a decrease in crown density and an increase in foliage transparency or a combination of these. It is not known whether tree number 108 died from the factors described above.

4.6.4 Epicormic Growth In October 2012, 22% of the tagged trees showed epicormic growth (51 trees) when compared to September 2011 when 19% of trees showed epicormic growth. A slight increase in epicormic growth occurred when compared to the March 2012 assessment (17%) which indicates an increase in the growth of trees and potentially an improvement in tree health or alternatively a sign of stress. Overall, a decline in trees showing epicormic growth is evident when compared to the initial tree health assessment undertaken in September 2010.

4.6.5 Flowering/Fruiting In October 2012, several of the Peppermint trees were recorded as flowering and/or budding. General observations were made on flowering and fruiting during the October 2012 site visit.

4.6.6 Presence of Western Ringtail Possum Two WRPs and seven possum dreys were recorded from the 230 tagged trees during the October 2012 survey. The possums and dreys were scattered over the site. These recordings were opportunistic sightings and not considered to be a comprehensive assessment of the presence of WRPs present at the site. Comprehensive WRP assessments were undertaken by Coffey Environments in 2009, 2010, 2011 and 2012. Coffey Environments undertook comprehensive drey surveys in 2009, 2011 and 2012. Further information regarding the outcome of detailed possum surveys are located in the letter correspondence cited in Section 1.3.

4.7 Digital Multi-Spectral Imagery The true and false colour imagery for the September 2012 and October 2011 fly-overs are provided in Appendix B and C. The September 2010 imagery has been used as baseline imagery for subsequent flights (including the October 2012 flight) to determine changes in the plant cell density, more commonly referred to as change detection.

A comparison between the September 2011 and October 2012 data has been undertaken. A comparison between two comparative months (i.e. September 2011 compared with October 2012) provides greater clarity in the leaf cell density change. The potential error provided by climatic conditions (i.e. summer drought compared with winter rain) is generally mitigated when similar months are compared.

4.7.1 Change Detection Change detection or Plant Cell Density (PCD) change is a simple remote sensing image analysis technique for measuring plant canopy density and health. The PCD (Infrared Reflectance/Red Reflectance) is sensitive to the quantity of leaves in each pixel (sample) and the density of healthy plant cells in those leaves. The Red band (675 nm) is positioned at maximum absorption by leaf chlorophyll content and the Infrared band where the leaf structure of healthy plants strongly reflects incoming energy.

SpecTerra mapped the resulting PCD change based on the tree polygons drawn by SurvCon Pty Ltd. The PCD change for the period October 2011 to September 2012 is provided in Appendix F. PCD change for the period October 2010 to September 2012 is also provided in Appendix G for comparison. The PCD change is based on the results of these three data acquisition periods.

PCD change is depicted in the change detection map for the period October 2011 – September 2012 (Appendix F). As the SpecTerra September 2012 PCD fly-over was undertaken following the removal of 60 trees at the site, these trees represent the maximum loss of PCD at the eastern part of the site during this period. Minor loss of PCD is also evident in the north-eastern and southern parts of the site, indicating a decline in tree health. Small areas of maximum gain in PCD are evident in the far north eastern and isolated areas located to the north of the site. DMSI mapping during this period shows the majority of trees at the site showed no change in PCD.

PCD change mapping of the site for the period October 2010 to September 2012 was examined for comparison. As expected the maximum loss of PCD is reflected in the removal of trees in the eastern portion of the site in September 2012 (Appendix G). Moderate loss of PCD was also identified in parts of the north-eastern and southern parts of the site. Minor losses of PCD were also represented in trees located in the north-eastern and western portions of the site. Maximum gain in PCD was represented in small areas located to the north of the site and one larger area located near the hospital building. These results indicate a reduction in PCD over the spring period and an overall decline in tree health at the site over time since initial monitoring began.

5. DISCUSSION AND RECOMMENDATIONS

5.1 Discussion Monitoring undertaken in October 2012 identified an increase in the mean combined vigour class of trees. An increase in the value of the mean combined vigour class indicates a reduction in the percentage of live tree canopy and therefore a decline in tree health. The decline is evident when the results are compared to the mean combined vigour class results recorded for the same period in September 2010. Tree vigour is a useful indicator of tree health and monitoring undertaken from September 2010 to October 2012 shows a consistent decline in the health of trees at the site.

Mean crown density across all transects and individual trees decreased in October 2012 when compared to the September 2011 results. Trees at the site have shown a decrease in mean crown density by 5.54% since the initial spring monitoring was completed in 2010. The decrease in mean crown density demonstrates a reduction in crown volume and a decline in tree health.

Mean foliage transparency increased to 75.43% in October 2012. The results show a slight increase in mean foliage transparency of 1.85% when compared to the previous spring assessment. The results illustrate a reduction in crown volume and an increase in the absence of foliage, both of which indicate a decline in tree health at the site.

Evidence of crown dieback was identified in all of the tagged trees at the site. A distinct transition in the classification of trees in various dieback categories was apparent during the spring 2012 assessment. The majority of trees assessed for crown dieback in spring 2012 were classified in dieback category 2 or 3 during monitoring of the site. When compared to the previous spring assessment in 2011, the majority of trees were classified into categories 1 and 2. In spring 2010, the largest numbers of trees were classified in dieback category 1 which indicated trees contained very little dieback during this period. The outcome of the three tree health assessments signifies an increase in the number of trees with crown dieback at the site.

Crown dieback is common in native bushland and can be a result of insect or fungal attack or a deficiency in water, nutrients or trace elements in the soil or the age of tree limbs. In general trees experience and can cope with crown dieback at a small scale; however, crown dieback coupled with other environmental factors (i.e. drought) can cause detrimental effects on the tree, with the loss of large limbs or the entire tree itself. Crown dieback was observed in either the smaller, outer branches of trees or large branches or dead limbs.

Borers and termites were present in 74 of the trees during the spring 2012 assessment. A slight decline in the numbers of trees with insects present was observed. The decrease in the number of trees with insects present may be the due to the removal of 60 trees prior to when the spring 2012 assessment was undertaken. Many of the trees that were removed showed signs of insects present in previous tree health assessments. Observations on insect damage were not comprehensive and are open to observational error. The evidence of borers during previous assessments would still be present and may have provided bias into the assessment. The number of new borer holes is hard to determine.

Borers may include beetles, wood moths, weevils and termites. Usually tree borers refer to beetles and their larvae. Borers interrupt the phloem (organic nutrient transporting system) and xylem (water transporting system) passages of the tree. Disruption to these systems can have adverse impacts on individual trees and may result in a decline in overall tree health or even tree

death. Trees affected by termites may disturb the structural integrity of branches and limbs. As a result tree branches and limbs become more susceptible to breakages during strong winds, storms or when tree limbs cannot support their own weight. Often insects invade trees in poor or declining health and this is indicative of trees at the site.

In October 2012, one new tree, Agonis flexuosa, had died since the previous monitoring was undertaken in March 2012. A number of trees at the site showed a decline in tree health and this was evident from an increase in tree vigour class, an increase in crown dieback, or a decrease in crown density and an increase in foliage transparency or a combination of these. The cause of death of this tree is unknown.

Monitoring in October 2012 identified a small increase in the percentage of trees (22%) with epicormic growth when compared to last year (September 2011) when only 19% of trees showed epicormic growth. A small increase in the percentage of trees with epicormic growth was also recorded within the year, when compared to the March 2012 assessment (17%). This increase in the percentage of trees with epicormic growth is to be expected in spring due to more favourable growing conditions (i.e. winter rain). The increase in rainfall during the winter months (June, July and August) for 2012, compared to the 2010 and 2011 totals, may have triggered the increase in epicormic growth. Overall, a decline in trees showing epicormic growth is evident when compared to the initial tree health assessment undertaken in September 2010. Busselton has recorded a cumulative rainfall total of 974mm over the three winter months from 2010 to 2012. This is over 370mm less than the cumulative average for the three winter months for 2010, 2011 and 2012.

Epicormic sprouting is a response mechanism normally experienced after a wildfire has swept through an area or the tree is responding after a period of stress such as drought or severe insect attack. The burnt tree survives the fire and sprouts new growth from epicormic buds that were protected from the fire under the bark. The cause for the epicormic growth on site may be numerous, but suggests that the health of the trees are in decline.

The September 2012 PCD fly-over was undertaken following the removal of 60 trees at the site, and as anticipated these trees represent the maximum loss of PCD at the eastern part of the site during this period. Minor loss of PCD is also evident in the north-eastern and southern parts of the site, indicating a decline in tree health. Small areas of maximum gain in PCD are evident in the far north eastern and isolated areas located to the north of the site. DMSI mapping during this period shows the majority of trees at the site showed no change in PCD when compared to October 2011.

Similar results were evident when PCD change mapping of the site for the period October 2010 to September 2012 was examined. The exception was in the south-western corner of the site, where there was no change in PCD. However, there was an increase in the number of trees showing minor loss in the north eastern part of the site. These results indicate a reduction in PCD over the spring period and an overall decline in tree health at the site since initial monitoring began.

The approved Western Ringtail Possum Management Plan (Coffey Environments, 2012b) has a set of triggers regarding tree health and tree deterioration. The trigger levels for decline in tree health will be considered as either:

• A catastrophic decline, which would be considered a 20% or greater reduction in tree canopy.

• A general decline in tree health of 30% or greater of the entire site (as determined through aerial imagery).

Excluding the approved removal of 153 Peppermint trees (including the 60 tagged trees), the current tree health trends are not nearing the two trigger levels described above. The October 2012 monitoring, having taken into consideration the approved tree removal, will act as the baseline from which the health of the trees will be measured against these trigger levels in the future.

The decline in tree health may be due to a decrease in the water table in different parts of the site or salinisation of soil due to changes in groundwater depth. Competition for nutrients and sunlight may also be the cause of changes in tree health and tree decline in northern parts of the site. Trees located here are denser than in other areas. Trees located at the southern portion of the site do not need to compete for nutrients and sunlight as these trees are more evenly spread across this area.

A review of existing information and data available on Peppermint decline suggest there is a range of factors potentially causing decline in tree health. These include declining water tables, drought, loss of native understorey and beneficial soil microbes, insect infestations, changed fire regimes and plant fungal diseases. Some of these factors or a combination of these factors may contribute to the decline in Peppermint trees throughout the south-west of Western Australia (Dakin et al., 2010). Based on the information available for the Busselton Hospital site it is possible that all of the above factors, with the exception of changed fire regime, may impact the health of the Peppermint trees. It is recommended that groundwater data is examined to determine whether groundwater drawdown or the quality of groundwater is influencing the health of trees at the site.

It is likely that late winter rains in 2012 and higher recorded temperatures than mean monthly temperatures in the Busselton region have adversely impacted Peppermint trees at the site. Although winter rainfall recorded in 2012 was slightly higher than in the previous year, historical rainfall data for the area indicates a trend towards decreasing rainfall in the region (BoM, 2012). Actual temperatures recorded for Busselton were higher in 2012 (BoM, 2012). A reduction in rainfall and the trend towards a drying climate are also likely to have an impact on tree health. Trees at the site may also be susceptible to unknown environmental factors that may cause undue stress and are not necessarily a consequence of development at the site.

GeoCatch (Geographe Catchment Council) are investigating the decline in Peppermint trees in the Busselton region with the assistance of the Centre of Excellence for Climate Change, Woodland and Forest Health (CCWFH). A number of treatments are currently being trialled to improve the health of Peppermint trees, including injecting nutrient supplements in tree trunks and stems. Nutrient supplements used on unhealthy trees may prevent further decline or supplements may be used on healthy trees as a preventative measure. Liaison with GeoCatch should be considered to determine methods which may improve Peppermint tree health at the Busselton hospital.

5.2 Recommendations Based on the results of the October 2012 and previous tree health assessments the following recommendations are made:

• As insect borers were noted as occurring within the Busselton hospital site, it is recommended that an Integrated Pest Management (IPM) plan be prepared and implemented to control the insect borer infestation within the site.



26

• Upgrade the existing Busselton hospital reticulation to provide additional water during tree planting and periods of prolonged drought. Reticulation will need to be amended following the removal of 60 trees at the site in September 2012.

• Discuss options of nutrient enrichment of trees located at the site with GeoCatch or an equivalent organisation. Nutrient enrichment may assist with improving the health of the trees.

• Review the groundwater levels in the Busselton region with the Department of Water to determine whether there is a drawdown of the groundwater table in the area that may be affecting tree health.

• Incorporate additional planting of understorey species into the site design to increase understorey density throughout the site and improve environmental values.

• Minimise vehicle access over the hospital grounds where there are no formal parking bays or driveways to prevent soil compaction and damage to tree roots, especially the fine feeder roots that are located closer to the surface.

• Prepare a rehabilitation strategy and management plan for the site. The rehabilitation strategy should include provisions to improve the understorey of trees, minimise vehicle access, control weeds, provision of mulch, insect control, watering regimes and nutrient supplements for the Peppermint trees.

• Where practical, obtain regional DMSI data from SpecTerra to determine whether the Peppermint trees in the Busselton region are in decline or the decline in tree health is restricted to the Busselton hospital site.

• The DEC and the CCWFH should be contacted regarding regional Peppermint tree studies that have been, are currently, or proposed to occur in the South-west of Western Australia.

• Ongoing monitoring of the health of the trees, including SpecTerra’s DMSI assessment, is undertaken on a six-monthly basis in consideration of the trigger levels set out in the approved Western Ringtail Possum Management Plan. The next tree health monitoring is due to be conducted in March 2013.
