Philip Hewett, City of Newcastle NSW
In the early 1930’s the industrial city of Newcastle NSW, encouraged by Mayor Ald C J Parker, began extensive
planting of trees, especially Hills Weeping Fig, to ameliorate the environmental and visual impacts of its mining and steel making industries. Some of the inner city streets were planted with Hills Fig in the unsealed road shoulder or in the footpath. The surviving mature fig trees now extend many metres over and above roofs because most buildings have shallow or non-existent street setbacks.
David Bidwell, Senior Horticulturist, Arboriculture, at the Sydney Royal Botanic Gardens thinks the earliest planting of Hills Fig in NSW is the stand lining Art Gallery Road in the Sydney Domain. These trees were planted in 1915. Unfortunately at least three of the trees are infected by the root pathogen Phellinus noxius. (pers comm) By the early 1930’s these Sydney Domain Figs would have given little indication of their mature form so Newcastle’s pioneering tree planters had little, if any reliable information about the ultimate size, both above and belowground, of the Figs they were planting in city streets during the 1930’s.
Over the last two decades many of the original Hills figs grown in Newcastle streets have been removed due either to failures, or to unmanageable conflicts with property, utilities, roads and infrastructure. Many of the surviving trees form tall, dense, interlocking canopies in streets and footpaths of the inner city. In common with most fig species, Hills Fig develops root buttresses producing a pronounced zone of uplift of 2 to 3 metres width. When growing in a street environment this uplift inevitably displaces kerbs and pavement, blocks fractures pipes, and become interlocked with buried utilities.
Throughout their first forty years the Newcastle Hills figs were routinely lopped to create a round-headed form of a ‘manageable’ size. The lopping created a low vase-like branch structure and when lopping was abandoned in the 1970’s the trees grew rapidly to form a tall multi-stemmed character.
Of all the issues relating to mature Hills figs in Newcastle streets, it is the linear (parallel to kerb) form of the root plate that presents the greatest challenge in managing risk. The close spacing (often less than 10m) between individual trees has created asymmetric and interlocking crown architecture. Linear root plates and
crown asymmetry are characteristics that contributed to the failure of Hills Fig trees in Tyrrell, Bruce, and Laman streets, Cooks Hill
In February 2012, after nearly three years of intensive investigation, reporting and debate extending across two elected Councils, three General Managers and two Acting General Managers, the remaining fourteen trees in the Laman Street cultural precinct were removed in accordance with the Council resolution.
What did the City of Newcastle learn from the Laman Street experience and what, if anything, could other tree management authorities glean from the Newcastle experience?
This paper is focused mainly on the engagement processes rather than on the technical issues relating to the Laman Street trees. The General Manager, Phil Pearce succinctly clarified Council's position on the technical and risk issues in his January 2012 Media Release (Appendix 1):
“Council has undertaken substantial investigation and analysis using both internal and external experts in arboriculture, engineering and other relevant professions. These experts have based their opinions on detailed knowledge of the site, evidence-based investigations and readily available relevant literature.
Council is very comfortable with the conclusions drawn from those reports and the decision by the majority of
the democratically elected Council to remove and replace the trees”
The Laman Street Engagement Processes – what was learnt?
In October 2011 Council directed the General Manger to conduct a review of the Laman Street fig tree issue
and report on an evaluation of the processes adopted by Council, with recommendations for improving
Councils engagement processes in respect of issues of major community significance.
The report (1) Review of Laman Street Engagement Processes (the Review) was presented to Council in February 2012.
Insights from the review of the Laman Street engagement processes may be of value to Councils and other authorities responsible for sustaining the benefits of urban forests despite a preponderance of mature aged trees approaching time for renewal.
Council has been investigating tree failures throughout the Local Government Area since 2000 resulting in the
collation of data known as the ‘case book history’ and adoption of a more strategic approach to assessing and managing trees.
The Review, prepared by staff selected because they had little or no direct involvement in the Laman Street processes, included a chronology of tree specific events from 2000 to 2011 and the associated Laman Street communication strategies and Council decisions – 243 separate items are listed.
The sheer volume of information on the topic prepared by Council officers made it impossible to review all the
information. However a significant amount of information was reviewed to inform the report and recommendations including:
- Media releases and clippings
- Factsheet prepared for ABC television Stateline story
- Transcripts from Public Voice meetings
- Results of the Civic Cultural Precinct Laman Street Design workshop
- Newcastle Voice 2010 and 2011 consultation reports
- A Case History Informing Tree Management in Laman Street
- Minutes of Council Project Control Group meetings
- Presentation for the Councillor workshop held on 27 July 2010
- Council resolutions pertaining to the Laman Street fig trees
- Minutes of the Laman Street Fig Trees Working Party
- Minutes of the Urban Planning and design Advisory Committee
The Review analysed the following four aspects of the engagement process:
- Community consultation methodologies and processes used by Council
- Scope of information supplied to councillors and the community
- Methods of communication between Council administration, Councillors, key stakeholders, community groups and the media
- Function and operation of the Laman Street Fig Trees Working Part, relevant strategic advisory committees and Council.
The following are the principle points of interest to other organisations from each of these four aspects. I have added underlining in order to emphasise points.
Community consultation survey results
With the benefit of hindsight, the decision to transfer the decision-making for what was an operational issue
managing tree risk) was not appropriate as it implied that alternatives could be considered when the
evidence showed only one option was appropriate. This resulted in unnecessary and at times inaccurate debate in the Council chamber, public forums and the media.
Combining the Laman Street fig tree replacement strategy with the consultation process for the broader Civic Cultural Precinct design process was intended to provide opportunity for the community to have direct input into the new design. However some community members perceived that the future of the figs was still to be determined when in fact the decision had been made.
A recommendation to hold a community information session ahead of the design workshop was rejected because of concerns about increasing antagonism in the community and fears that those opposed to the decision would seize control of the session for their own purposes.
Not holding the information session may have impac ted on the c ommunity’ s ability to participate in the workshop in a meaningful way, as they may have not fully understood the complex issues, the decision-making processes, or their role in the process.
Social media as a communication tool. It was found that contrary arguments clouded the discussion as they were disseminated through formal and social media at the same time as the design workshop presentations. Council’s communication strategy did not make use of social media.
Workshop timing. Feedback received on the timing of the two-day design workshop was that it should not have been held on weekdays.
Scope of information supplied to Councillors and the community
Management of the Laman street issues extended across two elected Councils, three General Managers and two Acting General Managers and in that time Council officers provided Councillors with a large volume of information consistently reinforcing that the trees pose a significant risk to public safety including:
- Root plate architecture
- Wind loading
- Quantified risk assessment
- Social impact assessment
- Heritage assessment
- Fauna habitat assessment
- Trenching investigation
- Feasibility study for tree restraint system
- Feasibility study into pull testing
- Peer reviews of previous independent reports
Since April 2010 all independent reports addressing Laman Street trees were made available on Council’s website to mitigate criticisms about Council’s motives and decisions. A range of other materials were also posted to the website to enable the community to gain a full understanding of tree management in general and Laman street trees in particular.
The community campaign took advantage of:
- social media,
- Public Voice presentations (by way of formal presentation to the full Council in chamber)
- letters to the editor
- individual representations to Councillors and the General Manager
- reports from other authors supporting the contrary position
A key finding was that respondents to the various surveys indicated that they expected a ‘ju st d o it app roach ’ from Council, where significant issues are decided on and actioned swiftly without the use of excessive funds or resources.
Respondents also commented on the need for the information to be completely transparent, where they are
provided with simple, h onest, easy to understand ’facts’ from the onset.
The overwhelming number of requests from Councillors, community groups, the media, and members of the public impacted significantly on Council Officers ability to complete their regular duties. On average the Media Officer receives 70-100 requests a month regarding Council activities. In November 2011 over 200 requests were received on Laman Street alone.
The problem was exacerbated because there was no officer designated to manage the flow of information in and out of the organisation. This resulted in multiple areas working at times simultaneously on similar requests.
An Issues Management Plan was developed by the Communications unit to deliver a comprehensive information campaign to educate the community about the issues but the plan was not implemented due to other organisational priorities at the time.
From early 2010 there was an active campaign opposing Council’s position and criticising Council’s information and officers. This, combined with the media’s sustained coverage of the opposition’s position resulted in the Council’s key message of public safety being lost or diluted. A strategy of media releases to counter the claims was discussed but was not adopted.
When Council made efforts to correct misinformation, the information provided to journalists was rarely published.
A more proactive approach was adopted in late 2011 involving media interviews with the General Manager, including ABC’s Statewide program, publication of ‘Fig Forum light on facts’ (Appendix 2) on Council’s website, and a full page community announcement in the Newcastle Herald.
Methods of communication between Council administration, Councillors, key stakeholders, community groups and the media

What were the most useful communication tools?
The Councillor survey indicated that the most useful communications tools were briefings, advice and meetings with the General Manager, and memos.
The community survey indicated Local Newspapers and word of mouth as most useful.
Whilst Council employed traditional communications methods, community groups implemented an active campaign using alternative methods including social media and letters to the editor of the Newcastle Herald.
It is understood that the Newcastle Herald does not fact check letters before publishing them and this resulted in erroneous information being presented to the public. Council responded to some of the letters but the
publication cycle of the newspaper meant that Council’s response could not be published until the following day so there was a delay of at least 24 hours before correction.
Function and operation of the Laman Street Fig Trees Working Party, relevant strategic advisory committees and Council
Council’s Strategic Advisory Committee structure allows for working parties to be formed reporting to the ‘parent’ committee which then reports to the Council as a whole.
Following a Council resolution on 14 December 2010, the Urban Planning and Design Advisory Committee (UPDAC) adopted a framework on 10 February 2011 for the composition of the Laman Street Tree Working Party (LSTWP).
There was a contradiction within the original Council resolution and within the Terms of Reference for the Working Party that compromised the success of the LSTWP from the outset. Both include the retention of the existing trees and implementation of alternative risk mitigation strategies. However, the basis of all the independent assessments had been the risks posed by the trees, and the issue for Council and its insurer were that no acceptable risk mitigation strategies could be implemented to adequately address these risks.
The contradiction arose because the Council resolution to create the Working Party was raised as a Motion without notice so Council Officers were unable to provide advice on the Motion before it was resolved.
Had the officers been able to provide advice the contradiction could have been removed facilitating a more productive outcome for the Working Party.
The minutes of the Working Party mimicked debate in the Council chamber and in the public arena as membership of the Working Party consisted of members holding both points of view, resulting in a debate focussed on contradicting the evidence supplied by Council Officers, discrediting the independent risk assessments, and rejecting any additional data.
On several occasions comments were made by Councillors that were not aligned with Council resolutions. This
enc ouraged protestors in their c riticism of Council’s decisions.
Council’s Media Policy states:
- Council officials should support Council decisions and should refrain from using the media to make negative personal reflections on each other or comments that could be interpreted as such and which are reasonably likely to undermine public confidence in the Council or local government generally.
- As members of the community, Council officials are entitled to enter into public debate and make comment on civic affairs provided they do not give the impression they are speaking in their official position for or on behalf of Council
Conclusions of the Engagement Processes Review
- A consistent message was delivered to the community and Councillors about Council’s position regarding risk management of trees and the need to remove the trees in Laman Street to ensure public safety.
- An active community campaign opposing the removal of the trees and a reactive approach to communications by Council for the issue resulted in alternative views clouding the overwhelming evidence presented to Councillors and the community.
- It is important to develop and apply appropriate issues management strategies to ensure the community is fully informed about Council activities
- It is equally important to carefully identify which issues require development of these strategies as the resources required to manage such issues can be quite extensive and may impact on officers’ ability to complete their normal
Recommendations of the Engagement Processes Review
The following is not a complete list of the recommendations; rather, it lists the recommendations of interest to other organisations facing the inevitability of renewing cultural plantings as part of sustaining urban forest benefits within a responsible risk management framework:
- Develop an issues management strategy for issues of major community significance to include:
- a dedicated project manager to oversee all activities including engagement with the community
- an appropriate budget to ensure effective engagement activities are supported
- an appropriate overarching community engagement plan as part of an overall project plan
- Develop strategies to better utilise social media to introduce and manage issues
- A directive stating that issues of major community significance, that are also identified as posing a high risk to safety, should be clearly communicated so that the community can be informed on the issues at hand and councils re However community consultation in such matters would not be required as this would provide an expectation that the community would be able to provide feedback on an operational issue
- Develop an Engagement Framework and an awareness campaign on the differing levels of public participation, based on the IAP2 spectrum.
The Path ahead – intergenerational equity – sustaining the urban forest
In June 2012 Council adopted a design for renewal of the Laman Street cultural precinct. Work, commencing in September 2012 includes construction of extensive load bearing root vaults as the foundations for establishing an avenue of purpose grown Hills Figs. The trees will define a people friendly cultural heart to Newcastle. The estimated construction cost of $1.8 million is an investment in a long-term vision founded on the principle of intergenerational equity.
Dr Greg McPherson (2) Director of the Centre for Urban Forest Research, California, touched on the essence of the Laman Street issues, at the end of his 2009 tour of four Australian capital cities, he observed:
“The transformation of mature urban forests, from forests of the past to forests for the future, poses problems
in many communities. Renewal of the urban forest is particularly complex in Canberra, where the historic quality of its streetscapes is integral to the character of its neighborhoods. Can the emotional debates about tree removal and replacement become a touchstone for broader public understanding and support? “
“The public landscape along streets and in parks is the last vestige of greenspace, and needs to be redesigned for maximum functionality”.
The Laman Street cultural precinct is one such ‘public landscape along a street’ that is being ‘redesigned for maximum functionality’.
Finally, two personal observations from the Laman Street issues
The first concerns the public perception of commercial arboriculture. Throughout the life of the Laman Street issue a community group opposing the removal of the trees engaged a number of commercial arborists to give their opinions about Council’s risk assessments and reporting.
Despite Council’s extensive and readily accessible technical reporting detailing the investigations, the facts, the evidence and the findings, commercial arborists contributed the following statements relating to the Laman Street trees :
- “…. there is no evidence that the trees have moved in the slightest or are in anyway structurally compromised.”
- “All of the Laman Street figs are structurally sound”
- “No evidence the trees are dangerous and the level of risk is akin to falling out of bed”
- ‘‘A blind person can see the trees are structurally sound and in good condition at the moment”
- “The level of risk is marginal for several of the trees but many of the trees currently present virtually no risk as they would fall into an adjoining tree if they were to fail”
- “The current root morphology is more than adequate to support the trees to date and there is no evidence that the trees have moved in the slightest or are in anyway structurally compromi”
- “There has been an assertion that these trees (sic) fig trees pose an abnormal level of risk yet to date all evidence suggests otherwise”
- “To date there is no quantifiable evidence that suggests that these trees have a greater risk of fail”
These and many more such statements contained in tree reports and media statements provided by community groups and prompted a Council officer to ask, “What do you call a group of arborists?” “A controversy!”
This sentiment was echoed during the December 2010 Public Voice hearing when a Councillor said, “I’ve been very much reliant upon reports and I’ve read very many reports on this matter. What I’ve learnt from those reports is that arboreal science is far from being exact and you can get somebody to write your report to support your point of view regardless of what it happens to be.”
These comments should ring alarm bells for all arborists and arboriculture organisations as they suggest the industry has a professional credibility problem that risks ‘tarring us all with the same brush’.
The complexity of information, the statutory framework, the political and social circumstances and the dynamic nature of the Laman Street trees gave decision-makers (elected and administrative) a monumental task. In the end it boiled down to judging the credibility of arborists and the veracity their information. With statements like those quoted above, perhaps their task was made that much easier?
My second observation is that those concerned with identifying defects and assessing their connective significance with respect to cultivated Hills Fig, should find Dennis Marsden’s 2006, 2007 and 2009 reporting on the Laman Street trees a very useful resource. His reports detail and discuss symptoms and defects contributing to Hills Fig failures in Newcastle. These include the cluster wedge, the ‘I’ beam formation, bark inclusion, compression forks, notch defects, root plate linearity and crown asymmetry.
Dennis made the following observation on the assessment of trees such as Hills Figs growing in streets and other highly developed urban spaces:
“In assessing the subject trees, we are not dealing with trees that fit neatly into test book examples of horticultural ideals and well defined defects, rather, we are dealing with a departure from the ideal and the departure takes us out of the text books and into the grey areas that are neither perfect nor so far in the opposite direction to perfect that tree removal is instantly and unequivocally warranted” (3)
This observation points to the challenge facing arborists responsible for managing large, ageing trees in confined concrete and asphalt street environs.
