Amani is home to African violet (Saintpaulia), which are thought to have a spiritual component (power of forgiveness) to the native Shambaa people, has enormous ecological value in the Amani ecosystem. The region is listed as one of the top 12 bird-watching locations in the world by Bird Life International, and the Reserve is a recognized Man and Biosphere Reserve by UNESCO.[2]
History
The Amani Nature Reserve was established in 1997 in a forested area in the East Usambara Mountains with an area of 83.8 km2 (32 sq mi), including the Amani Botanical Garden of 3 km2 (1.2 sq mi) and a further 10.7 km2 (4.1 sq mi) of forest managed by local tea estates. Traditionally, people living in villages adjacent to the reserve have used the forest as a source of timber, firewood and medicinal plants, a place to gather plants, bush meat, honey and fruit for consumption and a source of live birds, amphibians, reptiles and invertebrates for international trade.[3][4]
A growing problem in the area is the presence of the invasive West African tree Maesopsis eminii. This tree germinates readily from seeds which are spread by birds, springs up in gaps in the canopy and outperforms native tree seedlings, displacing rare endemics and reducing biodiversity. The forests of East Usambara have long been separated from other forests and their isolation makes them more vulnerable to invasive species such as M. eminii.[6]
Fauna
The fauna of the Usambara Mountains has been compared to that of the Galápagos Islands in terms of its richness and biological importance. The area of the Amani Nature Reserve is better studied than many other parts of the range with numerous endemic invertebrates dependent on the native moist forest cover including mites, spiders, freshwater crabs, dragonflies, beetles, butterflies, millipedes and molluscs.[7]
There are few large mammals in the reserve. Duiker and bushpig are plentiful and there are two species of monkey, but the elephants and leopards that used to inhabit the area are no longer present.[5] The elusive long-billed forest warbler (Artisornis moreaui) is known from the reserve and from one other locality, Mount Namuli in northern Mozambique, 1,000 km (600 mi) away.[8][9]
Founded in 1902, after World War II the scientific station became famous for its research into malaria. Since the 1970s the laboratory has remained largely unchanged with the specimens and instruments of a long gone by era. As of 2017 the station receives few visitors and the thirty-four staff maintain the entomological collection continuing to add butterflies and other insects.[11]
Attractions
The reserve is endowed with a variety of tourist attractions in addition to Saintpaulia flowers, including endemic species of flora and animals, Unique biodiversity, natural features, and historical and cultural attractions. The reserve is renowned for its diverse bird and butterfly species.[12]
