Site description The site contains the major block of 1,260 ha of native forest in south-west Mauritius that lies to the north of the Black River Gorge system, together with adjacent exotic vegetation. The site includes the plateau above the gorge (Pétrin to Tamarin Falls); the gorge itself east of the Rivière Noire and Grandes Gorges river (including the ridges of Macchabé and Brise Fer); the west-facing Magenta escarpment; and Tamarin Gorge to Rempart mountain. The plateau areas are 550–660 m above sea-level, and the escarpments and gorge slope down almost to sea-level; the highest point, Rempart, reaches 777 m. Rainfall decreases from east to west, from 3,500 mm annually at Pétrin to below 1,500 mm on the coastal plain. Diverse types of native upland and lowland forest and thicket are present, together with a large expanse of exotic vegetation, especially around the entrance to the Black River Gorge. Most of the native vegetation is within the Black River Gorges National Park. Land outside the park is mainly privately-owned Mountain Reserve or leased State Land, some of which is used for deer-hunting.
