The forest of Monte Lerno is situated in the province of Sassari, within the territory of the municipality of Pattada. It stretches uncontaminated for a surface area of 2853 hectares and is characterised by the presence of a rich vegetation of numerous holm oak woods. A few years ago the territory in which the wood was present was much larger than the present one, but a fire reduced its surface. The reforestation currently in progress gives the visitor an idea of how important the care and the maintenance of the territory is to this community. A natural wood of holm oaks is discreetly preserved at Sos Littos. From the present floristic composition of the vegetation of this area it should be noticed as a wood in re-evolution that preserves many elements of the tall brush (phillyrea, strawberry tree, etc.). The whole area also has a sizeable number of cork oaks with abundant brushwood dominated by rockrose, heather and strawberry tree. The best cork oaks inside the perimeter are found at Trataxis. The quality of the cork of this territory is particularly appreciated by producers, because of its high yield and quality. The colours of the vegetation along with the presence of ample spaces in which it is possible to spend a day in the open air, are good reasons to invite the tourist for a visit to the forest.
