This site is a one of the largest Natura 2000 sites in the Maltese islands. It covers an area of approximately 180 hectares. Its seaside slopes are characterised by a mosaic of two habitats, calcareous rocky slopes and vegetated sea cliffs with the presence of a widespread species, the Maltese sea lavender. The inland part of the site is dominated by garigue intermixed with Mediterranean salt steppes, which combination forms as a result of having soils temporarily permeated by saline water and subject to extreme summer drying.

A small but important holm oak forest remnant can be found in Wied l-Imġiebaħ. A permanent spring is also present in this site at Għajn Ħadid, which allows a humid environment owing to the water-retaining abilities of the abundant exposed blue clay in the area. Consequently, a large proportion of the area in this site is also agricultural.

The L-Imġiebaħ/Tal-Miġnuna Natura 2000 site hosts a small sandy beach known as ir-Ramla ta’ l-Imġiebaħ.

It is a secluded beach amidst particularly beautiful scenery and natural surroundings.

This Natura 2000 site will be subject to the preparation of a management plan and/or legislation in the near future, as part of an EU funded project that Mepa is undertaking for the management planning all the terrestrial Natura 2000 sites of the Maltese islands.
