What it shows
This layer delineates France's Type 1 Natural Zones of Ecological, Faunal and Floral Interest (ZNIEFF). These are areas of limited extent that are notable for the presence of rare or remarkable species, species assemblages or habitats characteristic of the national or regional natural heritage. A site within or near one of these zones sits in an area of recognised ecological sensitivity, which can carry heightened regulatory and reputational attention.
How it is built
ZNIEFF is the French national inventory of areas of ecological interest, maintained by the national natural-heritage authorities. Type 1 zones are the smaller, more sharply defined units, identified on the basis of confirmed presence of rare, remarkable or characteristic species and habitats. This layer presents those inventoried zones as fixed boundary polygons; it is a designation map rather than a graded risk score.
How to read it
This is a presence layer. A site that intersects or lies near a Type 1 polygon is flagged as falling within an inventoried area of high ecological interest. There is no 1–5 score; the signal is whether a location coincides with a designated zone.

Comparison with the WWF Risk Filter Suite
This is a French national inventory layer with no direct global equivalent in the WWF Risk Filter Suite. It extends area-based coverage related to BRF S14_1 Protected/Conserved Areas and S14_4 Other Important Delineated Areas regionally, beyond the global datasets WWF relies on.
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 |
