Gunung Sewu
From Wikipedia, the free encyclopedia
Gunung Sewu (Thousand mountains)[1] is the name for the karst region of southern central Java that lies to the south east of Yogyakarta, south of Surakarta, and is considered a very dry and poor socio-economical region in Java. It has poor rainfall compared to the volcanic mountain areas to the north and east. Administratively most of the region is part of Gunung Kidul Regency (within the Yogyakarta province) besides Wonogiri Regency (in Central Java Province) and Pacitan Regency (in East Java Province). In 1993, the world speleologs proposed Sewu Mountains Karst Area as a world heritage. And on December 6, 2004 Sewu Mountains and South Gombong have been announced as eco-karst.[2]
It is a region where archaeological evidence shows very early human activity [3]
It is very popular with cavers.[4][5] There are 119 caves below of about 40,000 karst cone hills in 13,000 square kilometer area.[2] The only cave-adapted crab from Java, Sesarmoides jacobsoni (Sesarmidae), is endemic to the Gunung Sewu cave system.
