Bromo Tengger Semeru National Park (
The Tengger Sand Sea has been protected since 1919. The Bromo Tengger Semeru National Park was declared a national park in 1982.[5]
Geography
Tengger massif
The Tengger massif is a massif within the park.[6][7] The area is an active volcanic complex surrounded by a plain of sand.
Volcanism
The volcanic complex of Tengger forms a condition where a new caldera of volcano forms inside a larger and more ancient caldera. There are five volcanoes inside the Tengger Caldera: Mount Bromo (2,329 m), Mount Batok (2,470 m), Mount Kursi (2,581 m), Mount Watangan (2,661 m), and Mount Widodaren (2,650 m). Mount Batok is the only peak that is no longer active, and is covered in casuarina (Indonesian: cemara) trees. Mount Widodaren, located beside Mount Batok, contains the cave Widodaren, which is considered sacred by local people.
The five volcanoes within the caldera are surrounded by a vast area of sand called the Tengger Sand Sea, which in turn is surrounded by a steep crater wall of the larger Tengger Caldera with height differences of about 200–600 meters (660–1,970 ft). Other mountains around the Tengger caldera are: Mount Pananjakan (2,770 m), Mount Cemorolawang (2,227 m), Mount Lingker (2,278 m), Mount Pundak Lembu (2,635 m), Mount Jantur (2,705 m), Mount Ider-ider (2,527 m) and Mount Mungal (2,480 m). The peak of Mount Pananjakan is the most popular place to watch the entire volcanic complex of Tengger.[8]
Further south in the national park, there is another volcanic complex called the Semeru Group or Jambangan Group. This area contains the highest peak of Java,

Ecosystem
According to height and temperature differences, the forests within the area can be classified into three zones:
Sub-montane zone (750 – 1,500 m)
This zone is classified as a tropical rainforest. It can be found in the southern area of Semeru, East Semeru (Burno), and West Semeru (Patok Picis). This zone is dominated with plants of the families
Montane zone (1,500 – 2,440 m)
Plant life is greatly reduced in this area. Most of the species that grow in this area are
The Tengger Sand Sea in Tengger Caldera is a special ecosystem. The area is covered in volcanic sedimentation of sand from Mount Bromo activities. The resulting area is believed to be the only known desert-like area in Indonesia. The Tengger Sand Sea has been protected since 1919.
Subalpine zone (above 2,400 m)
The flora that cover this area are mentinggi gunung (
On Mount Semeru, there is no plant life above the altitude of 3,100 m. This zone is covered in loose sandstones.[10]
