New input: Marojejy National Park is located in the northeast of Madagascar between the towns of Andapa and Sambava and extends approximately 32 km (20 mi) from east to west and 22 km (14 mi) from north to south. It is centered on the chain of mountains known as Marojejy Massif. Despite a scientific survey of some of the other mountains in the region by the 1929 Mission Zoologique Franco-Anglo-Americaine, Marojejy was not surveyed until 1937 when L.-J. Arragon of the Service Geographique de Madagascar ascended Marojejy Est. Arragon did not conduct any field research during his visit. The massif was not geologically described until after the French botanist Jean-Henri Humbert from the National Museum of Natural History in Paris explored the mountains in 1948. Humbert had previously explored numerous mountain ranges in continental Africa before going to Marojejy. Between November 1948 and November 1950, he spent five months collecting 4,039 dried plant (herbarium) specimens for study. After several expeditions, he published the book "A Marvel of Nature" in 1955, in which he claimed the massif was the most impressive range in all of Madagascar because of its size, floral diversity, and pristine natural state.Marojejy was set aside as one of Madagascar's strict nature reserves in 1952 largely due to Humbert's enthusiasm and support. Under this protection, only research scientists were permitted to visit the site. In 1998, Marojejy was converted into a national park and thus became open to visitors.Originally seen as a transition zone between the eastern rainforests and the central highlands, Marojejy is now recognized as having its own unique features, with some of the richest biodiversity on the island. Several studies from the early 1970s through the 1990s surveyed the mountain ecosystems and inventoried the flora and fauna. In 2007, Marojejy was listed as a World Heritage Site as part of the Rainforests of the Atsinanana. Due to illegal logging and trafficking of valuable hardwoods, and especially after the 2009 political crisis in Madagascar, the Rainforests of the Atsinanana was added to the list of World Heritage in Danger in 2010.
