There are more than 900 species typical of dry evergreen forest habitats – i.e. aloe, euphorbia, pachipodium, etc. – to be seen here, set out on display over an area of 100 acres . Ninety percent of them are endemic to Madagascar and eighty percent have medicinal properties.
The process of creating this collection of the region's native plants has actually led to the discovery of new species.
The trees here are also home to various species of birds. There are in fact 34 to be seen in total at Antsokay, as well as a large number of reptiles and other animals, among them the famous mouse lemur, the world's smallest lemur. It is also possible to observe the animals at night at Antsokay.
Allow two hours to look round the arboretum, which also has a small fossil and mineral museum.
