Zones proposed by the 2nd National Nature Protection Plan (PNPN2) from 2017 in view of the designation as protected areas of national interest, that are currently undergoing the official designation procedure (are approved by the government council). These zones do not yet have legal protection status and as such are not subject to special constraints. The delimitations are not definite and can be adapted during the designation procedure.

Their legal protection status is available at the layers "Protected areas undergoing the official designation procedure" and "Designated protected areas".

Protected zones of national interest (nature reserves and forest reserves) according to amended law of 19th January 2004 concerning the conservation of nature and the naturally resources. Each area and reserve is burdened with obligations defined by grand ducal regulation.
