STRATA™ is Structured Tree Risk Assessment and Tracking Analysis
Tree Risk Management with STRATA™
A structured digital approach to tree risk assessment, professional recommendations, work priorities and ongoing management.
STRATA™ helps arboricultural professionals inspect trees, record supporting evidence, evaluate risk and make proportionate management recommendations—all within a digitally mapped tree-management workflow.
Each assessment remains connected to its photographs, recommendations, Works Priority, completion records and future reinspection requirements, creating a clear management history from initial inspection to completed action.
Professional Judgement Remains with the Surveyor.
The surveyor remains responsible for the recommendation. STRATA™ provides a consistent structure for evaluating and recording evidence while allowing the competent arboricultural professional to determine the most appropriate action for the tree and its surroundings.
See how STRATA™ supports the complete tree risk management process in one connected digital workflow.
Risk Framework
Support consistent tree risk assessments using a clearly defined method and management process.
Built-In User Guide
Access practical STRATA™ User Guide from the app while completing the tree survey workflow.
Mapped Evidence
Connect observations, photographs, recommendations and priorities to each tree.
Tracked Actions
Follow tree work recommendations through to completion, sign-off to reduce or remove the risk.
The Tree Management Challenge
Tree risk management does not end when the inspection has been completed. Recommendations must be communicated, prioritised, monitored, completed and reviewed.
When tree survey information, tree work instructions and reinspection records are held separately, it becomes harder to maintain a clear and reliable tree management history.
Common Problems
- Tree Survey findings held in separate reports and spreadsheets.
- Recommendations passed manually between teams.
- Limited visibility of outstanding or overdue work.
- Difficulty confirming whether the tree work has been completed.
- Reinspection dates managed separately.
- Inconsistent records between tree surveyors or tree contractors.
The Mapscape STRATA™ Solution
STRATA™ brings the assessment, recommendation and management response together in one connected record.
- One mapped record for each surveyed tree.
- Evidence and recommendations recorded in the field.
- Clear Works Priorities and action timescales.
- Recommended work retained against the tree record.
- Optional photographic tree work sign-off.
- Reinspection information connected to the original tree risk assessment.
Arboricultural Evidence → Recommendation → Works Priority → Reporting → Work Completion → Sign-off Works → Tree(s) Reinspection
STRATA™ Supports the Arborist
Tree risk assessment decisions require professional knowledge of tree biology, defects and disorders, site use, ground conditions, potential targets within falling distance of the tree in all directions and the available management options.
STRATA™ addresses this by creating a consistent framework structure around this tree risk assessment process, while allowing the competent tree surveyor to determine the tree work recommendation(s) they consider most appropriate for the tree and its surroundings.
This combines:
- Professional discretion for the surveyor
- Consistent digital records for the business, organisation and/or tree owner
- Transparent reasoning for the client or duty holder
- Printable reports and site plans
Professional Arboricultural judgement within a consistent and auditable tree risk management digital framework.
How Mapscape and STRATA™ Supports Tree Risk Management
STRATA™ guides the surveyor through a structured tree risk assessment process, while retaining the flexibility to apply professional arboricultural judgement. Results are immediately available to office staff in preparation for report finalisation to assist priority based decision making.
1. Inspect the Tree and Record Findings
Record tree details, observations, defects, photographs and other relevant site information during the field inspection.
2. Consider the Tree(s) Target Zone
Assess the area in which people, property, vehicles or other potential targets could be affected.
3. Evaluate the Risk to the Target Zone
Use the structured STRATA™ framework to consider probability, consequence and the site context.
3. Make Tree Work Recommendation(s)
The surveyor determines the most appropriate management action, priority and supporting rationale.
5. Complete and Produce Risk Report
Produce outputs, monitor recommended work, record completion and manage future reinspection.
5. Sign-off Tree Works
Reinspect the tree(s) to check the recommended tree works has been completed.
Tree Risk Assessment to Sign-off Works
Capture evidence at the tree – Record observations, defects, measurements, photographs and site information directly against the mapped tree. This reduces the need to transfer handwritten notes or rebuild the survey record after returning to the office.
Communicate priorities clearly – STRATA™ converts the structured assessment into a clear Works Priority and timescale for action. Colour-coded mapped records help surveyors, managers and clients understand where attention is required.
Track work, sign-off and reinspection – Recommended work remains connected to the original tree record. Using Mapscape Sign-Off Works, completed actions can be recorded with photographs and comments, while future reinspection requirements remain visible.

Clear Reports for End User Action
STRATA™ helps turn tree risk assessments into information that can be used by surveyors, managers, contractors and clients.
A soon as information out on site is recorded, it is ready to convert into a Excel spreadsheet that automatically places all your tree survey data for trees, groups of trees and hedges into one Excel spreadsheet, in the right cell ready for final editing and conversion to PDF.
Automated Reports
- Tree details and inspection observations
- Photographic and mapped evidence
- Recorded defects and recommendations
- Works Priorities and action timescales
- Reinspection and management information
- Exportable Excel and PDF outputs
Producing Site Plans
- Digitally mapped tree locations
- Target-zone context
- Colour-coded work priorities
- Trees, groups and hedges
- Site boundaries and surrounding features
- Optional mapping and data layers
The result is a clearer connection between what was observed, what was recommended and what happens next.
Frequently Asked Questions
Find answers about professional arboricultural judgement, guidance, work sign-off, reinspection and trying STRATA™.
What is STRATA™?
STRATA™ is Mapscape’s structured digital approach to tree risk assessment and management. It supports field inspection, evidence recording, professional recommendations, Works Priorities, reporting and future management.
Does STRATA™ replace professional judgement?
No. STRATA™ provides a consistent assessment framework, but the competent tree surveyor retains the ability for interpreting the arboricultural evidence and deciding the works priority and most appropriate recommendation for tree works.
Can surveyors make their own recommendations?
Yes. The tree surveyor can record the action they consider appropriate for the tree, the site and the surrounding targets, together with the supporting rationale.
Does STRATA™ include guidance?
Yes. STRATA™ is supported by a click through User Guide and a separate Method and Framework document. to provide to the end user that is incorporated in the Excel spreadsheet as a link to the Mapscape repository.
Can completed tree work be recorded?
Yes. Mapscape Sign-Off Works can be used to record completed tree work recommendations using comments, photographs and a clear completion status.
Can completed tree work be recorded?
Yes. Tree information can be mapped and organised across multiple projects, properties or operational areas and any scale.
Can different surveyors use the system?
Yes. STRATA™ provides a consistent workflow that can support individual surveyors, teams, subcontractors and multi-site organisations.
Can reinspection dates be managed?
Yes. Reinspection requirements can remain connected to the tree record and be monitored through Mapscape’s management tools.
Is training provided?
Mapscape onboarding and system guidance is provided to help surveyors and managers understand the STRATA™ workflow.
Can we see STRATA™ before purchasing?
Yes. A demonstration can be arranged to show the field assessment, mapped outputs, recommendations, work tracking and reporting process.
