Sealed Judgement

1 B ACKGROUND
The original RACV Noosa development site surveys were undertaken between 2019 and 2022
to record the trees in consideration of the proposed tourist accommodation project. This
Arborist Review should take into consideration the previous Arborist Reports, Spreadsheets
and all other relevant project plans and documents.

To gain an accurate understanding of the treescape on the site, the detailed tree surveys
involved an assessment of each tree recorded from a ground level. The following data was
recorded:

   x   Botanical Name & Common Name,
   x   Age Class,
   x   Health,
   x   Structure,
   x   Approximate size in meters - Height, Crown Spread, DBH at 1.4m
   x   Retention Value - awarded based on health, condition, age, and importance to the
       local environmental community, with a focus on consideration of Koalas.
   x   Comments were recorded relating to observations noted at the time of the inspection,
       including notes regarding the invasive Frangipani Vine, Chonemorpha fragrans,
       spreading across the site and growing into many of the trees.

Initially, the tree survey included the road reserve on the eastern side of the site and the koala
tree species within the Noosa Council River reserve on the western side. Due to the high
number of undesirable Umbrella trees across the site, these were not recorded to avoid
distorting the data of the overall site assessment. It is intended to remove all the Umbrella
trees as part of the site weed management.

The trees are tagged and clearly numbered. CadCon surveyors accurately plotted the
locations of each tree so that detailed plans with each tree's position could be considered as
part of the design. This process of identification throughout the site streamlined the task of
reassessing each tree in August 2024 and March 2025. In many cases, photos of the trees
have been taken at different times.

The forest is a living entity that changes from day to day, and the status and condition of trees
will naturally alter. With the presence of the fast-growing invasive Frangipani Vine throughout
the site and within many of the trees, these elements needed to be reviewed to determine the
impact the vine is having on the trees' condition and ultimately their ability to function as a
viable tree. Photographs collected since 2019 can be used to demonstrate changes to the
trees and/or the status of the Frangipani Vine growth.

The data recorded was compiled in spreadsheets for analysis. This included calculation of the
Tree Protection Zone (TPZ) and Structural Root Zone (SRZ) as per AS4970-2009 Protection
of trees on development sites. Koala trees were identified under the guidance of Dr William
Ellis and were recorded based on species only. The data gathered was used to provide the
necessary information to guide the Arborist Reports and advise and assist with the
development of the plans.
