Site description The site comprises a steep-sided valley in the dry, north-western lowlands between St-Denis and La Possession, together with the lowest part of the Ravine à Jacques, 1 km to the north-east. It contains a few habitations at the river mouths, a tourist centre and a military firing range, but around 40% of the site is protected, as it is one of the last sites on La Réunion where dry evergreen lowland forest survives. Other major habitats are secondary grassland and exotic thickets; small areas of cliff and rocky shore also occur.
