The forest area has climatic conditions typical of the Mediterranean regime; winters are moderately cold, being able to take advantage of the thermoregulatory action of the sea with January being the coldest month (5.7 ° C) and hot summers with August being the hottest month (30.4 ° C).
From a geological point of view, the forest area is partly composed of sedimentary rocks of the Jurese with stratified dolomites and massive limestones and partly of granite rocks and basaltic rocks.
The Bidderosa coastal forest
It is made up of five compartments: Biderosa (532 hectares).
The forest includes five splendid coves, a popular destination for summer seaside tourism, which are managed by a local cooperative. The visit to this corner of Sardinia represents a unique opportunity to admire the extraordinary coastal panorama of the island which in this area offers an evocative succession of granite reliefs, garnished with centuries-old junipers, which frame the blue of the sea and sublime glimpses of a coast of white sand.
In the inland areas of Biderosa and Monte Tuttavista, the vegetation is spontaneous and consists of cork oak, holm oak and Phoenician juniper.
Also present in the forest are numerous specimens of dwarf palm (Chamaerops humilis), easily visible along the paths that run through the forest.
In the forest area there are also a small orchard and an olive grove with a total area of one hectare.
