See how green evolves. Steer with insight.
Understand how trees and green structures have changed over time.
From loss to growth, from data to policy action.
You can’t manage what you don’t track over time.
Governments are setting ambitious goals for nature, forests and biodiversity.
But:
- Historical insight into tree and green development is limited
- Data is often fragmented or inconsistent
- It is unclear where trees are lost or gained
- Trends are difficult to quantify
This creates key challenges:
- Are we actually increasing green areas?
- Where does tree loss occur?
- Is planting compensating for removal?
- Are we meeting national or European targets?
Without historical insight, policy lacks direction and accountability.
From snapshots to long-term insight.
Terramira makes the development of green visible over time.
Not just where trees are today.
But how landscapes are changing.
A foundation for monitoring, reporting and policy.
Compare. Quantify. Understand.
We analyse multiple years of tree and green data to identify changes.
We use multiple years of tree register data (from ~2010 onwards).
We identify:
- Tree loss-
- New tree growth
Changes in green structures
We quantify:
- Net change in surface area
- Gains vs losses
- Long-term trends
We analyse:
- Tree canopy volume (young vs mature trees)
- Tree type (deciduous vs coniferous)
At:
- Municipal level
- Regional level
- Provincial level
- National level
From change to policy direction.
Better balance between removal and planting
Understand where losses are compensated and where not.
Quality insight, not just quantity
Include canopy volume and tree maturity.
Support biodiversity strategies
Use tree type and structure insights for species management.
Built for long-term monitoring
The analysis provides:
- Trend analysis from ~2010 to today
- Net development in hectares
- Insight into removal vs planting
- Structural indicators such as canopy volume and tree types
Result:
A complete, time-based view of green development — not just a snapshot.
For policy, monitoring and reporting
Municipalities
Report on local green policies and developments
Provinces
Monitor regional trends and biodiversity strategies
National government (LVVN)
Track national targets such as forest expansion
