Professional Disclaimer: All trees are inspected on a basic level and ground based and should a higher level of inspection be required this will be identified and required to complete a mitigation response on individual trees. All trees are assessed on “normal weather conditions “and weather event outside this will be deemed an abnormal weather event and as this assessment results a higher level of risk than the initial assessment due to forces applied. After any weather event where there have been severe forces applied to the assessed trees, we strongly recommend a reinspection to keep your report current as this report prior to any event will be deemed defuncted until reinspected.

To inspect and assess all trees on site with current infrastructure and future infrastructure and staff and contractors as the basis for suitability for retention. All trees will be
view from species type , and long term suitability and if there are protocols relevant to retention during construction should the trees be retained.

Method of Inspection Kurt Brown employs a relevant section of multiple quantified modalities in his inspections, these are Matthecks VTA (Visual Tree Assessment) (Image 1) and ISA TRAQ Assessment. Kurt will also age profile the tree using the following classification in Appendix 2 and from this will give an approximate ULE (useful life expectancy) The following data was updated for the trees: • ID Number consistent with previous assessment or on a new site the initial numbering system • Image of tree • Botanic and common name • Tree dimensions (Height x Width) • Diameter at breast height (DBH) • Health • Structure • Useful life expectancy (ULE) • Age Class • Recommended works • Comments Appendix 1

The Visual Tree Assessment (VTA) methods as described in ‘The Body Language of Trees. A Handbook for Failure Analysis. Research for Amenity Trees’ by Mattheck and Breloer (Mattheck, et al., 1994) is used in association with the International Society of Arboriculture’s guidelines in this report. 196 THE BODY LANGUAGE G [ce © ROOT BUTTRESS © SAILAREA @ BOTTLE-BUIT @ SOIL CRACKS © VITALITY BREAKAGE WIND THROW - eaves - bark ~ tw DEFECT “ SYMTOMS FUNGI - bulges @ FUNG! 7bus © OLD BRANCHES WOUNDS @ LEANING ‘© BRANCHES: @BARK CRACKS ‘SUBSIDING @ OTHER ABNOR- MALTHINGS WOUND T OCCLUSION © KNOCKING WITH HAMMER © SOUND VELOCITY MEASUREMENT }@ RESISTOGRAPH NOCKING ® SOUND VELOCITY MEASUREMENT ‘@ REMOVE SOIL ESISTOGRAPH Fig 120.

Number (CM) rating
T1 Pandanus tectorius 7 7 29 M G F 5 to L This tree presents typically for the species in the coastal location. The habit is spreading because of the salt
15 spray from the ocean and as such the growth habit has been distorted laterally .
There is signs of insect predation and some structural concern’s and because of where they are in their age
cycle it is fair to look at removing as a better long term option and replanting in guidance with the vegetation
mapping for the area by Noosa Council .
T2 Canpanuopsis 8 9 41 M FG F 5 to L This tree presents typically for the species in the coastal location. The habit is spreading because of the salt

Arborist Conclusion Statement
Page 13
Trees 1 to 6 we agree long tern would be more suitable for removal with the factors of , 1. Where they are in their age cycle 2. Structural integrity due to extreme lateral growth 3. Insect predation and the signs of tree health is not as vigorous as the initial inspection showed 4. Continual salt spray issues We strongly recommend Kind regards Kurt Brown DIP Arb SCIT, ISA TRAQ Certified Australian Tree Contractors & Arboricultural Consultants Pty Ltd
