This protected area forms part of the Tal-Marċa valley system, which is characterised by a perennial spring which provides freshwater to the area all year round.

Consequently the flora and fauna of the area include various species requiring a constant freshwater supply, and include important riparian assemblages based upon the great reed and old white poplar trees (luq).

The area in question also houses one of the few populations of the endemic Maltese freshwater crab (qabru). The area has various protective designations, some also of international significance, which include the following: Natura 2000 Site; Area of Ecological Importance; Site of Scientific Importance; Nature Reserve; Special Area of Conservation of International Importance; and as a water body under the EC Water Framework Directive. Mepa declared this site as a Tree Protected Area on May 24, in accordance with the provisions of the Trees and Woodlands Protection Regulations (2011) as per Government Notice number 473/11.
