City of Busselton

GPS mapping and assessment of approx. 1000 trees for a redevelopment of a park within the City. The trees were surveyed using a Trimble GeoExplorer 6000 to map their locations and gather relevant data on each tree. The data was compiled in an Excel spreadsheet for ease of reference and then exported in shapefile for use with GIS and autocad software so the City can easily search and track the attribute data or overlay the tree point data onto site drawings to foresee potential tree construction conflicts.

Department of Parks and Wildlife - The Valley of the Giants

Arbor Guy conducted a site wide tree survey which involved gathering the precise location and specific attribute data on all significant trees within the Valley of the Giants. The trees were surveyed using a Trimble GeoExplorer 6000 to map their locations and gather relevant data on each tree. The data was compiled in an Excel spreadsheet for ease of reference and then exported in shapefile for use with GIS and Autocad software. Detailed site maps were created in QGIS to show all tree locations in relation to roads, buildings and infrastructure allowing site management to quickly and easily reference individual trees. The intention of the project was to provide management of the site with unprecedented data for the their planning and visitor risk management.
 
Consulting meetings prior to gathering the data meant a tailored report template could be developed to gather specific data relevant to the requirements of the walk; whilst meeting all arboricultural requirements as per the code of practice “pruning of amenity trees”.

Bunbury Cathedral Grammar School

Arbor Guy conducted a detailed assessment on approximately 900 trees throughout the school grounds. This was done using GPS and tablet technology. The data collected included; tree ID, height, diameter at breast height [DBH], health, structure, recommended works and Quantified Tree Risk Assessment [QTRA] “Risk Index”. The collected information was compiled in an Excel spreadsheet, Word documented report and a tree location plan for ease of reference.

Explorus Adventure Learning

Arbor Guy conducts an annual risk assessment involving the location mapping (GPS) of over 100 trees within and adjacent to the camp areas and high ropes course at the Explorus Outdoor Education Centre in Karridale, WA. The trees are assessed for health and safety reasons using the QTRA system and the data compiled in an Excel spread sheet and in a tree location plan.

Kookaburra Caravan Park (City of Busselton)

Over 250 trees were plotted and mapped on aerial photographs from the three individual park sites. Each tree was individually assessed, relevant data collected, comments and recommended works noted and photographs taken. The gathered information was collaborated and a spreadsheet developed that could be updated by the parks managers as works were conducted.


The principals of Quantified Tree Risk Assessment and Visual Tree Assessment were applied to the assessment allowing high risk trees to be identified and risk reduction works conducted immediately.
