Arboricultural Impact Assessment
AS4970-aligned assessments for development applications, infrastructure works and DA conditions.

Junglist Arboricultural Consulting provides independent technical advice on trees in the built environment — risk, retention, protection and the long-term stewardship of the urban forest.
Junglist Arboricultural Consulting is the practice of Martin Spencer, an arboriculturist with more than twenty-five years' work across urban forestry, tree risk assessment, development support and municipal asset management — most recently stewarding approximately one million public trees as City Arborist for the City of Gold Coast.
We work with local government, landscape architects, planners, developers and private landowners on the questions that trees pose to the built environment: whether to retain, how to protect, what to manage, when to remove. Our advice is technical, independent, and grounded in the Australian Standards.
"Trees are slow assets in a fast world. Good arboricultural advice buys time — for the tree, the project, and the community that will live with it."
Engagements range from single-tree risk advice through to long-form urban-forest strategy. A selection of the work the practice routinely undertakes is set out below.
AS4970-aligned assessments for development applications, infrastructure works and DA conditions.
TRAQ-qualified Level 1 and Level 2 inspections for landowners, councils and asset managers.
On-site supervision, tree protection compliance and root investigation during construction.
Policy, asset planning and species selection for municipal and master-planned tree populations.
Retention strategies and artificial-hollow programs that keep declining trees in service.
Technical reports, second opinions and independent review for legal and planning matters, including expert witness engagements for the Land Court and QCAT.
Conceived and championed during tenure as City Arborist for the City of Gold Coast, the program activated declining and dead habitat trees that would otherwise have been removed — installing more than 650 artificial hollows across parks, open space and natural areas.


We accept a small number of engagements each quarter — from single arboricultural impact assessments through to retained advisory work.
