Madagascar, from Rainforest to Highlands to Coastal Sediments

Madagascar - May 31st, 2012

Along the length of the eastern coast of Madagascar runs a narrow and steep escarpment containing much of the island’s remaining tropical rain forest, easily observable by the bright green strip of land along the coast. To the west of this ridge lies a plateau region in the center of the island ranging in altitude from 750 to 1,500 m (2,460 to 4,920 ft) above sea level.

These central highlands are the most densely populated part of the island and are characterized by terraced, rice-growing valleys lying between grassy, deforested hills. To the west of the highlands, the increasingly arid terrain gradually slopes down to the Mozambique Channel. Deforestation leading to erosion means that over the years more and more sediment from the highlands has run down the slope and into the channel.
