Undara

The savanna(h) plains of the Undara Volcano National Park are broken up by granitic and basaltic outcrops and several volcano craters, as well as one of the geological wonders of the world: an extensive system of caves and tubes formed by lava flowing from an eruption of the Undara volcano 190 000 years ago. Here the McBride basalts and resulting clay soils surround depressions formed by areas where the roof of the tubes has collapsed. These depressions support dry rainforest, a vegetation community allied to the rainforests of wetter eastern areas as well as cave-adapted fauna. The flora and fauna in these sheltered areas and on various outcrops contrast to the different flora and fauna of the surrounding woodland.
