What it shows
This layer delineates the forests and natural parks of Bangladesh. It identifies areas with formal forest and park designations, which tend to carry conservation value and associated legal, permitting and stakeholder considerations. For nature-related risk, it flags where a site or activity falls within or close to nationally recognised forest and park land.
How it is built
The layer is a set of mapped boundaries for Bangladesh's forests and natural parks. The original data comes from the Local Government Engineering Department of Bangladesh, and the dataset was subsequently updated by the World Food Programme, Map Action and the UN Office for the Coordination of Humanitarian Affairs. Each area is represented as a polygon outlining its extent, rather than as a measured value.
How to read it
This is a boundary layer. A site that falls within, intersects or lies near one of these forest or park polygons is flagged as overlapping a designated area, indicating heightened sensitivity and the likely need for closer assessment. Areas outside the polygons carry no designation here.
Class thresholds
This is a categorical presence / boundary layer, not a physical-flux quantity. It models the spatial extent of Bangladesh's designated forests and natural parks as polygons; each feature carries only a name (PathName) rather than a measured value, so there is no underlying physical unit and no numeric class breaks. The "classes" are simply presence versus absence: a location either falls inside (or overlaps) a designated forest/park polygon, or it does not.
There is no continuous-value threshold. The risk trigger is a spatial intersection: a site is flagged on the Sensitive areas dimension when it overlaps or lies near one of the forest/park polygons (and the entity's matching ENCORE "Sensitive area disturbance" pressure is also material). The layer configuration defines the proximity as a polygon intersection, with no fixed buffer distance.
How these thresholds were set. There are no thresholds to set — the layer is a presence/boundary mask. The polygon boundaries come directly from the source data (Local Government Engineering Department of Bangladesh, updated by WFP, Map Action and OCHA); Darwin applies only the intersection-based proximity gate, not any numeric classification.

Comparison with the WWF Risk Filter Suite
This layer relates to WWF Biodiversity Risk Filter indicator S14_1 Protected/Conserved Areas. WWF draws on the global World Database on Protected Areas; Darwin instead assembles this national dataset, which extends or localises protected-area coverage for Bangladesh.
Risk analysis
A site is flagged on a dimension by combining a proximity trigger (this layer) with an activity trigger (the entity's ENCORE pressure/service). Proximity only → Potentially material; proximity and the matching ENCORE pressure/service is material → Very material; neither → Not material.
| Dimension | ENCORE service / pressure | Proximity trigger (this layer) | Activity trigger (entity) |
|---|---|---|---|
| Sensitive areas | Sensitive area disturbance | Site overlaps / is near the feature | impact ratio ≥ 10%; “Disturbances (e.g noise, light)” pressure ≥ 4; “Introduction of invasive species” pressure ≥ 4; “Area of freshwater use” pressure ≥ 4; “Area of seabed use” pressure ≥ 4; “Area of land use” pressure ≥ 4; “Other biotic resource extraction (e.g. fish, timber)” pressure ≥ 4; “Volume of water use” pressure ≥ 4; “Emissions of non-GHG air pollutants” pressure ≥ 4; “Generation and release of solid waste” pressure ≥ 4; “Emissions of toxic soil and water pollutants” pressure ≥ 4; “Emissions of nutrient soil and water pollutants” pressure ≥ 4 |
