A BS5837:2012 survey identifies, measures and assesses the condition of every tree relevant to a site, and sets out the Root Protection Areas that follow from that assessment. It's the standard that most Scottish planning authorities expect to see before they'll consider a scheme that has trees anywhere near it. Statutory constraints — including any Tree Preservation Orders affecting the site — are identified and addressed as part of every survey; see the Tree Preservation Orders guide for how those work.

What's included
Survey & reportBS5837:2012 tree survey — species, dimensions, condition, category grading and Root Protection Area calculations for every tree on or adjoining the site.
Tree Constraints PlanThe survey data overlaid on the site, showing exactly where trees limit what can be built and where.
Arboricultural Impact AssessmentHow a proposed layout affects the trees worth keeping, and what that means for the design.
Method StatementProtective fencing, ground protection and construction-phase working methods, written to satisfy planning conditions.
An example Tree Constraints Plan: tree canopies and Root Protection Areas plotted over an aerial site plan.
A Tree Constraints Plan in progress — tree canopies and Root Protection Areas plotted against the site, ready to overlay on a proposed layout.

Survey data is collected and mapped through QGIS, CAD and DXF workflows, so crowns and Root Protection Areas are georeferenced rather than sketched — useful when a plan needs to sit accurately against a topographic or architect's drawing.

Recommendations on protection measures are written in performance terms — what the fencing or ground protection needs to achieve — rather than specifying one commercial product where an equivalent would do just as well.

Tree health & risk assessments, film & TV tree safety, and climbing work aren't listed here yet — see the About page for why, and get in touch if you're not sure whether your job fits.
