Wied ta’ Għajn Żejtuna
Wied ta’ Għajn Żejtuna is located within the settlement boundary of Santa Marija Estate in Mellieħa, flanked by villa development along most of its length. Formerly part of a much wider system, the valley is now limited to the valley-bed proper –which sustains a permanent freshwater spring – and its banks.
The constant source of freshwater flows from the Mellieħa perched groundwater body at the interface between the Mtarfa Member (Tal-Qawwi) and the Blue Clay formation.
The watercourse flows along the coastal rocky platform beneath Ix-Xatt ta’ Santa Marija, which, apart from maritime garigue, also contains a small shingle beach.
Part of the valley side supports a semi-natural woodland consisting of mature Aleppo pines (Pinus halepensis Mill.).
This particular valley is the only known locality in Malta for the extirpated Red Flax (Linum decumbens Desfontaines), a species that has a restricted distribution in the Mediterranean.
Mepa scheduled Wied ta’ Għajn Żejtuna, the coastal platform and the semi-natural pine woodland as a Level 2 Area of Ecological Importance. The scheduling was published via GN No. 872 of 2009, dated October 30, 2009.
