Beta
Upload your data, review the outputs, sign the report. ArbGen turns arborist-supplied data into structured analysis and draft reports. The judgement-critical decisions stay with you.
Preliminary Arboricultural Reports
TPZ and SRZ calculated live from your trunk measurements per AS 4970-2025. Species names filled in from either half of the pair. Tree location mapping and structured report output. Place trees on a spreadsheet, a shapefile, or the architect's PDF.
Arboricultural Impact Assessments Coming soon
Encroachment measured as the root zone area severed by the works, not just the ground it sits on. Recalculated as the works are drawn, with staged professional review.
Tree Protection Plans, Study Area maps and Tree Location Maps, drawn from your field data.
Your professional judgement
ArbGen drafts. You review, edit and approve. Every retention decision and recommendation stays yours.
Your accountability
Reports are authored under your name and qualifications. ArbGen is the tool, not the consultant.
Your time
Less time on data entry and formatting. More on site assessments and client work.
The AS 4970-2025 arithmetic ArbGen runs, on one tree at a time. No sign-in, nothing uploaded, nothing stored.
NRZ & SRZ Calculator
Trunk diameter in, root zone radius and area out, drawn to scale with the formulas shown. Girth as well as diameter, and a schedule for a whole site.
Encroachment Calculator
Drag the works over the zones and read the encroachment area, the share of the NRZ, whether the SRZ is touched, and the AS 4970-2025 category.
