Nature patiently worked to create this place over millions of years. The artists are wind and water, which have carved the rock, shaping majestic limestone towers, the Buttes of Ogliastra, between which some dense, luxuriant vegetation has developed and is crossed by torrents. This is the captivating landscape that makes the state-owned forest of Bingionniga stand out, as it extends for over 400 hectares, almost entirely in the territory of Jerzu, while a small part of it falls within that of Tertenia, at an altitude that varies between 250 and 750 metres. It is mostly made up of holm oak forests, with a lush undergrowth and species of phillyrea. In the areas where the holm oaks thin out, a dense Mediterranean scrub has developed, with strawberry trees, mastics, rockrose and heather making up the greenery. The rocky areas are particularly enchanting, with various native species like the coronilla and the terebinth. The waterways tend to have a seasonal flow: the main ones are the rivulets of Moliapas, Alusti and Su Crabiolu.
