Marfa Ridge may have once been covered in broadleaf woodland, but the original vegetation has long since vanished. Centuries of farming impoverished the soil, fields were abandoned and the land turned to sheep and goat pasture. A garrigue ecosystem developed where bedrock was exposed, while areas with some soil cover became rocky or clay steppe.
Through the Foresta 2000 project, many old, crumbling terraces were restored and native trees and shrubs were planted, like holm oak, Aleppo pine, lentisk, araar, Mediterranean buckthorn, hawthorn, carob, rosemary and olive-leaved germander. Today, they are growing back some of the woodland and undergrowth that was lost over the centuries.
At about 23ha in area, one day Foresta 2000 may rival Buskett in expanse, if not in age. Most of the area covered by the woodland project falls within a Natura 2000 site and is therefore, protected from harmful development. Foresta 2000 is managed by BirdLife Malta, Din l-Art Ħelwa and PARK.
