Tropical rain forest in the context of "Hkakabo Razi"

Terrestrial ecosystems are ecosystems that are found on land. Examples include tundra, taiga, temperate deciduous forest, tropical rain forest, grassland, deserts.

Terrestrial ecosystems differ from aquatic ecosystems by the predominant presence of soil rather than water at the surface and by the extension of plants above this soil/water surface in terrestrial ecosystems. There is a wide range of water availability among terrestrial ecosystems (including water scarcity in some cases), whereas water is seldom a limiting factor to organisms in aquatic ecosystems. Because water buffers temperature fluctuations, terrestrial ecosystems usually experience greater diurnal and seasonal temperature fluctuations than do aquatic ecosystems in similar climates.

Sumatra (/sʊˈmɑːtrə/) is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 482,286.55 km (182,812 mi.), including adjacent islands such as the Simeulue, Nias, Mentawai, Enggano, Riau Islands, Bangka Belitung and Krakatoa archipelago.

Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa archipelago, separates Sumatra from Java. The northern tip of Sumatra is near the Andaman Islands, while off the southeastern coast lie the islands of Bangka and Belitung, Karimata Strait and the Java Sea. The Bukit Barisan mountains, which contain several active volcanoes, form the backbone of the island, while the northeastern area contains large plains and lowlands with swamps, mangrove forest and complex river systems. The equator crosses the island at its centre in West Sumatra and Riau provinces. The climate of the island is tropical, hot, and humid. Lush tropical rain forest once dominated the landscape.

The Belize River runs 290 kilometres (180 mi) through the center of Belize. It drains more than one-quarter of the country as it winds along the northern edge of the Maya Mountains to the sea just north of Belize City (17°32′N 88°14′W / 17.533°N 88.233°W / 17.533; -88.233). The Belize River Valley is largely tropical rainforest.

Also known as the Old River, the Belize River begins where the Mopan River and Macal River join just east of San Ignacio, Belize (17°11′N 89°04′W / 17.183°N 89.067°W / 17.183; -89.067). The Belize River – Mopan River Catchment contains over 45 percent of the population of Belize. The Belize River, in spite of 78 runs or rapids, is passable via the Mopan to the Guatemalan border. It served as the main artery of commerce and communication between the interior and the coast until well into the twentieth century, and has long been associated with forestry, of logwood (for dye) and of mahogany which survives in small stands.
