1. Background

This Tree Protection & Removal Plan (TPRP) has been prepared to support the establishment and operation of the Cross Passage 15 site near the Princes Bridge and Yarra River as part of the Cross Yarra Partnership Tunnels and Station Works. It has been prepared for Cross Yarra Partnership and must not be used by any other parties other than those involved with the project.

In preparation of the plan, several site inspections have been completed to inform design and mitigate impact where possible. Details of the site and the overall condition of the trees were assessed during the inspections. This document does not make comment on the trees’ suitability for retention. This plan provides details of the trees which require removal, an assessment of their potential to be transplanted and tree protection actions to ensure that the trees retained are maintained and protected appropriately during proposed works.

The assessments have been based on the following plans:

• TAS-CYP-TUN-TCP-DRG-XTW-NAP-X2166-A.dwg

• TAS-CYP-TUN-TCP-DRG-XTW-NAP-X2101-E.dwg

• CMR18-0805DomainCP15YarraRiver.pdf

• TAS-CYP-TUN-TCP-DRG-XTW-NAP-X2180-D.dwg

2. Statement of Expertise and Involvement

This Tree Protection Plan has been prepared by Josh Smyth of C&R Ryder Consulting Pty. Ltd. Josh has both significant formal and practical training ensuring he is suitably qualified to complete these assessments.

6. Activities Restricted within the Tree Protection Zone

Unless approved by the Project Arborist or as specifically allowed in this Tree Protection Plan, the following activities are to be restricted within the Tree Protection Zone (TPZ). This list of activities has been adapted from the Australian Standard AS 4970-2009 Protection of Trees on Development Sites.

• Machine excavation including trenching

• Excavation for silt fencing

• Soil cultivation

• Storage of materials and or waste (including fuels, oils or chemicals)

• Preparation of any cement products

• Storage and or parking of vehicles and or any plant

• Wash down of equipment

• Placement of fill or site spoil or site level changes

• Lighting of fires

• Temporary or permanent installation of signs

• Installation of utilities

• Physical damage of any kind to the tree (including attaching anything to the trunk or branches)

A tree protection fence should be designed to be robust and withstand easy movement or ingress. Chain mesh fencing, temporary fencing panels or solid hoarding are all good examples (Figure 1). Appropriate signage is to accompany all TPZs with a minimum of 2 signs per tree (Figure 2). These can be supplied by C&R Ryder Consulting Pty Ltd.

7. Tree Management

The TPP is to cover the works planned near the Princes Bridge and Yarra River, Melbourne. The works will generally involve:

1. Removal of nominated trees

2. Establishment of tree protection fencing

3. Establishment of site hoarding, laydown/storage areas, site facilities and other associated works

4. Works to complete the tunnel construction beneath.

It should be noted that the proposed works are complex in space and over time.

Role of the Project Arborist

The Project Arborist is responsible for monitoring and certification of the TPP. Only the Project Arborist may vary the requirements of the TPP under written consent of the Responsible Authority. Only the Project Arborist may submit any staged reports as required by the TPP and or Responsible Authority.

Given the nature of the works, it is possible that the requirements for works exceed that of the TPRP. In this case, minor changes will be made under the supervision of and at the discretion of the Project Arborist. Any significant changes to the TPRP will be documented on the day.

If it is likely that the proposed changes will deleteriously impact the tree, works will cease until further investigation and design modification has been completed.

10. Proposed Removals

4 trees (DCOMTAS082, DN011, DN012 and DN017) will require removal to facilitate the design as proposed in TAS-CYP-TUN-TCP-DRG-XTW-NAP-X2180-D.dwg.

DCOMTAS082 will have considerable excavation in proximity to the main stem of the tree, although monocots do not have an allocated SRZ, the works are potentially up to or within the stem itself and the tree is likely to become unstable and/or be considerably impacted by the works. It will require removal to construct the retaining wall as proposed.

DN011, DN012 and DN017 are within the proposed works/setup and require removal to implement it as designed.

11. Transplant assessment

It is proposed to remove trees at CP15 as part of the site establishment. It is understood that transplanting trees rather than removal for Cross Yarra Partnership and is to be investigated. The following makes comment on the suitability of transplanting trees proposed for removal at CP15.

The trees proposed for removal/transplant are shown in Figure 4 and Figure 5. For the purposes of this assessment, all trees which may require removal have been considered for

of 31


their transplant potential, this includes DCOMTAS082, DN011, DN012 and DN017. The tree details are provided in Table 2.

Whilst large tree transplanting can be a success (Watson & Himelick 2013), it is largely dependent on:

• timing

• species of tree

• age and size of tree

• capacity for root preparation

• quality of transplant technique

• quality and length of after care.

It is understood that the trees need to be removed/transplanted in the short-term.

11.1 Root Ball Preparation

Trees DCOMTAS082 and DN012 are monocotyledons typically quite tolerant of the transplant process (Gilman 1997). They generally have fair to good health, beneficial when considering transplant (Harris, Clark & Matheny 1999).

Trees DN011 and DN017 are dicotyledons, which are generally more sensitive to the root disturbance required of the transplant process.

Typical pre-preparation of a dicotyledon involves a staged process, cutting sections of tree roots over time to minimise stress to the tree. Staged root pruning is often completed assuming a symmetrical, shallow root system as described by Costello (2009), Craul (1992) and Watson (1995). The reality in modified urban areas is that tree roots often grow in unpredictable locations, old trenches, disturbed areas, in leaking pipes or along irrigation lines and are not symmetrical at all. This has been observed repeatedly across the Metro Tunnel Project.

The Hong Kong Government’s guidelines on tree transplanting (2014) suggest that a trunk diameter to root ball diameter ratio of between 1:8 and 1:10 is common. On that basis, a tree with a trunk diameter of 300mm would require a minimum root ball diameter of between 2.4-3m.

Staged root pruning is largely unnecessary for monocotyledons and pre-preparation mostly consists of pruning the roots at the extent of the root ball prior to lifting the tree.

When specifying the required size of root ball for large single stemmed monocots Broschat and Meerow (cited in Hodel, Pittenger & Downer 2005) suggest that a root ball extending 30cm from the edge of the trunk and 60cm deep is generally sufficient to capture 50% or more of the roots. Considering the significance and cost of transplant, to maximise the likelihood of successful transplant and stability post-transplant, a root ball diameter of ~3m is recommended.

Table 3 details the estimated root ball requirements to be considered for the trees in question.

11.2 After Care

After care of the transplanted trees requires good irrigation practice and possibly guying for stability until the root system has re-established to its pre-transplant size. According to The Morton Arboretum (2016), approximately 1 year of recovery is needed for each 25mm of trunk diameter when dealing with dicotyledons. Thus, a tree with a diameter of 300mm would have a recovery period (under good growing conditions) of 12 years, during which time good irrigation management would be required. Due to the regenerative nature of their root

of 31


system, monocotyledons, although still requiring irrigation, are likely to re-establish an adequate root mass in a much shorter period. Table 3 details the estimated recovery times for the trees.

11.3 Site Constraints

The pre-preparation and tree digging described above for dicotyledons may be feasible for DN017 as it is located in open, flat park land but is unlikely to achievable for DN011 which has considerably altered landscaping and infrastructure installed around it, even if lead times, access and space requirements were achievable. In this instance, considering the size of DN011, there would be several difficulties in achieving access for suitable transport logistics. To successfully transplant DN017 staged root pruning over 6-12 months prior to transplant is required. It is understood that the trees require removal in the short-term.

While transplant of large dicotyledons is possible, in the urban context it is unlikely to be feasible without significant complexity, high cost, long lead time and should only be contemplated for trees of cultural significance.

As monocotyledons are not subject to the same constraints as dicotyledons, they are much more suitable for transplant. Their retained root ball is significantly smaller and commensurately less expensive to prepare, lift and transport; and they require much smaller lead times for preparation. Suitable transport logistic access will still require careful consideration as several of the trees are in tiered garden area, difficult to access and may require removal of several stone walls which form the retained tiers.

Maximum root development of palms is generally in the warmer months of the year (Hodel, Pittenger & Downer 2005) and ideally they would be transplanted during spring or early summer, although transplanting outside of the warmer months is not unheard of, especially in warmer climates where root development is likely to continue through the cooler months (Broschat 1998).

11.4 Transplant summary

The following comments are made in relation to the suitability of transplanting the trees from the CP15 site:

• Dicotyledons - DN011 & 017

− DN011 is likely to have a large, asymmetrical root systems requiring the removal of considerable hard infrastructure to prepare a suitable root ball.

− Identifying, specifying and removing a suitable root ball for DN011 is likely to be prohibitively difficult considering the required size.

− Considering the tiered aspect of its current growing location, finding a suitable location to relocate DN011 would also prove difficult.

− DN017 is a semi-mature specimen suitable for transplant with a reasonable lead time.

• Monocotyledons – DCOMTAS082 & DN012

− These are species much more tolerant of transplant due to the nature of their root systems.

− Root ball sizes are not prohibitive and could be achieved with careful planning.

− Ideally, to maximise likelihood of success, they would be transplanted in spring or early summer.

− Determining transplant location may still prove difficult considering the size of the trees.

− Lifting and transport logistics will still be difficult considering the size and location of the trees.

12. Specific Actions

Trees to be removed

Following final determination of trees to be removed, they are to be marked by the Project Arborist. Any tree removals are to be performed by suitably qualified arborists with a minimum Certificate III in arboriculture (or equivalent).

Trees on the tiered garden area

Trees DCOMTAS038, DCOMTAS076, DCOMTAS077, DCOMTAS078, DCOMTAS079, DCOMTAS080, DCOMTAS081, DCOMTAS083, DCOMTAS084, DCOMTAS085 and DCOMTAS086 are to have fencing installed around their respective TPZs (Figure 6). Considering the tiered nature of the garden bed and that the area is unlikely to be disturbed after the retaining wall has been installed, parawebbing on star pickets with tree protection signage may be the most appropriate fencing installation. Approximately 125m of parawebbing will be required and minimum of 13 tree protection signs.

Figure 6: Tree protection fencing, in the form of parawebbing and signage, to surround trees DCOMTAS038, DCOMTAS076-081and DCOMTAS084-086 on the tiered garden bed.

of 31


Trees DN014 and DN026

Tree DN014 is to have fencing installed around it. As DN014 is within a permeable lawn area, the entirety of TPZ is to be protected and fenced; this will require 12 panels of temporary fence, associated concrete bases and a minimum of 4 tree protection signs. DN026 is outside of the project boundary, is surrounded by existing hardstand, has hoop barriers installed at the edge of permeable tree pit and is unlikely to be impacted by works or use of the site; as such it requires no further tree protection (Figure 7).

DN018, DN019, DN020 and DCOMTAS039

These trees are proposed to be outside of the site compound, but jersey barriers are to be installed within, or close to, their TPZs. The installation is likely to require use of heavy machinery in proximity to the trees and is to be supervised by the Project Arborist (Figure 7).
