Measure landscape connectivity.
Understand how green and blue elements connect your landscape and where improvement is needed.
Turn spatial insight into targeted biodiversity policy.
Biodiversity depends on connection, not just protection
Nature areas alone are not enough to sustain biodiversity.
Species depend on connected landscapes beyond protected zones.
But in practice:
- Small landscape elements are fragmented or disappearing
- There is limited visibility on connectivity outside nature areas
- Data is inconsistent across regions
- Policymakers lack a clear, measurable baseline
This makes it difficult to answer:
- How connected is our landscape today?
- Where are gaps in ecological structure?
- Where should we invest to improve biodiversity?
Without measurable insight, connectivity remains an assumption.
From landscape elements to policy insight
Terramira provides a clear, objective view of green-blue connectivity across regions.
Not just maps.
A measurable indicator.
A foundation for policy.
Map. Quantify. Prioritize.
We analyse the presence and distribution of green and blue landscape elements outside nature areas and urban zones.
We identify elements such as:
- Hedgerows and tree lines
- Ditches and natural banks
- Small vegetation structures
We distinguish between:
- Gross surface (all elements)
- Net ecological value (only relevant elements counted fully)
We quantify the share of green-blue elements per area.
Outputs include maps and indicators at:
- Municipality level
- Regional level
- Provincial level
- Grid (hexagon) level
We scale results to catchment, regional or industry level.
From insight to biodiversity action.
Scalable and comparable
Apply one consistent method across regions.
Future-ready reporting
Prepare for potential EU Nature Restoration requirements.
Track water targets
Integrate connectivity into land use and development decisions.
Already applied in practice.
- Implemented for multiple provinces (approx. 6)
- Designed for regional and national policy use
- Based on consistent methodology across areas
Result:
A comparable, scalable view of green-blue connectivity.
For biodiversity and spatial policy
Provinces
Develop and monitor biodiversity strategies
National government (LVVN)
Support national-level policy and reporting
Municipalities
Apply regional insights to local planning
Frequently Asked Questions
GBDA measures the percentage of ecologically relevant green and blue landscape elements outside nature areas and urban zones.
It enables species to move between habitats, which is essential for biodiversity and ecosystem resilience.
Elements such as hedgerows, tree lines, ditches and natural banks are included in the analysis.
Gross includes all elements, while net focuses only on ecologically valuable structures.
Not currently, but it is strongly policy-driven and it will be linked to future EU regulations.
connectivity visible.
Understand where your landscape connects and where it doesn’t.
