Standards alignment

One module, every standard your client expects.

From DNO vegetation management to BS5837 development surveys to highways condition assessments — the surveying module adapts to the framework.

ENA G55/2

Utility arboriculture categorisation, risk and defect recording aligned to network operator standards.

BS5837:2012

Trees in relation to design, demolition and construction — full survey schema and constraint plans.

DMRB LA 104

Environmental assessment and monitoring outputs in National Highways-compatible formats.

DMRB LA 119

Biodiversity and habitat-focused field surveys aligned with highways environmental reporting.

Utility Arboriculture

Built for the operational reality of vegetation around lines.

Designed in line with the requirements used by Distribution Network Operators, framework contractors, vegetation management teams and infrastructure asset owners.

Utility-specific data capture

Capture what utility surveys actually need, not generic arb fields — and generate standardised outputs suitable for utility frameworks and infrastructure contracts.

  • ENA G55/2 aligned tree categorisation
  • Utility-specific risk ratings and defect recording
  • Span and conductor proximity measurements
  • Vegetation-to-line clearance recording
  • Hazard tree identification and prioritisation
  • Cyclical vegetation management planning
  • GIS utility corridor mapping and access planning
  • Emergency storm damage and reactive works workflows
  • Integrated traffic management and road space planning
  • Mechanisation recommendations based on terrain & access
Survey features

Every measurement, every condition — captured once.

Survey teams rapidly assess vegetation risk, ecological impact and access constraints across complex infrastructure environments.

DBH, height, spread & age class

Full condition recording with consistent data quality across teams and contractors.

RPA auto-calculation

Root Protection Areas calculated automatically — no spreadsheet workarounds.

Risk & work priority scoring

Defensible scoring methodology with full audit trail for client handover.

Vegetation density & habitat

Habitat classification and density mapping support both ecological and mechanisation planning.

GIS clearance & retention mapping

Visualise clearance zones, retention areas and constraints alongside the corridor.

Optional QTRA integration

For frameworks where Quantified Tree Risk Assessment is required.

i-Tree Eco & Canopy

Ecosystem service data capture for valuation, ESG reporting and BNG support.

Drone-assisted canopy & ash dieback

Thermal and visual drone surveys feed straight into the corridor record.

Satellite & aerial change detection

Compare historic survey data against current conditions for cyclical maintenance.

Drone, GIS & Change Detection

Remote sensing as a first-class citizen.

Integrated GIS and remote sensing tools turn passive aerial data into active operational triggers.

  • Drone-assisted thermal surveys
  • Ash dieback hotspot identification
  • LiDAR and orthomosaic compatibility
  • Vegetation growth and regrowth monitoring
  • Automated corridor encroachment detection
  • GIS-linked ecological stop-work zones

The system compares historic survey data against current conditions, supporting cyclical vegetation management programmes and proactive asset maintenance — so issues are escalated before they become network risks.

what3words Field Locator

Three words to find any tree on the network.

Every 3m × 3m square in the UK has a unique three-word address. Pin trees, machines and access points with sub-3m precision — even on unmapped tracks, in dense canopy or on remote upland corridors.

  • Pin individual trees with a three-word address
  • Tag machine current location and depot positions
  • Reverse-lookup from GPS coordinates in the field
  • Share precise access points with subcontractors and emergency teams
  • Direct API integration with the official what3words service
  • Field pin CSV export bundled into job packs
  • Geolocation capture from any modern device

Particularly powerful for rural utility corridors, motorway verges and rail cuttings where a postcode is meaningless and an OS grid reference is too slow to share verbally over a radio.

AI Species Identification

Species, hazards and growth rates — at a tap.

Built-in species database covering common utility-corridor trees with biosecurity risk, average growth rate, mature height and clearance management notes.

Ash (Fraxinus excelsior)

HIGH biosec — Hymenoscyphus fraxineus (ADB)

Growth 0.6–1.0 m/yr · max 35 m · fast-growing, high clearance priority.

Oak (Quercus robur)

HIGH biosec — AOD / OPM risk

Growth 0.3–0.5 m/yr · max 40 m · slow-growing, long-term management.

Sycamore (Acer)

LOW biosec

Growth 0.5–0.9 m/yr · max 35 m · prolific regrowth after pruning.

Poplar (Populus spp.)

LOW biosec

Growth 1.0–2.0 m/yr · max 30 m · very high growth — frequent cycle.

Elm (Ulmus spp.)

MEDIUM biosec — DED risk

Growth 0.4–0.8 m/yr · max 30 m · watch for Dutch Elm Disease signs.

Larch (Larix)

HIGH biosec — Phytophthora ramorum

Felling licence required · notify Forestry Commission before works.

Biosecurity protocols

Stop pathogens travelling with your kit.

Movement restrictions, cleaning protocols and Forestry Commission notification triggers applied automatically by species and site.

Hymenoscyphus fraxineus (ADB)

Critical · RESTRICTED movement. Clean tools between trees. Chip or burn material on site. Notify Forestry Commission for any works greater than 1 ha.

Acute Oak Decline / OPM

High · CONTROLLED movement. Check for OPM nests April–August. Do not move oak material in season. PPE for ground crews near OPM sites.

Dutch Elm Disease

Medium · CONTROLLED movement. Remove bark before any movement of elm material. Avoid sap-rise season.

Phytophthora ramorum

High · RESTRICTED movement. Felling licence required on larch. Notify Forestry Commission before works. Wheel and tool wash mandatory.
