Sensitive Natural Space

Sensitive Natural Spaces (Espaces Naturels Sensibles, or ENS in French) are designed to protect areas where high-quality natural, landscape or geological heritage is threatened or made vulnerable by urbanisation or the development of private interests or activities.

In addition to this conservation mission, during certain periods of the year some ENS are open to public to raise awareness, as long as this is not incompatible with these fragile sites.

Sensitive Natural Spaces were established by the general councils of territorial divisions in France. In order to support Sensitive Natural Spaces, a specific tax can be levied: the Sensitive Natural Space Tax (TDENS) on planning permits.

The funds from this tax are then used to acquire, restore, develop and manage threatened natural environments. Ownership and management of these spaces may be made the responsibility of territorial divisions or even approved third parties (associations, coastal protection institutes, etc.).
