Restoring the vegetation cover and the native forests of biodiversity hotspots in Mauritius

Since 2010, 2.5 ha of Citadel and 18 ha of Petrin were restored with endemic trees. This reforestation project is aiming at conserving the unique biodiversity of Mauritius, allowing complete re-vegetation of the 11 ha of Citadel, reintroducing endemic ecosystem at Petrin which are invaded by exotic alien plants and preserving the ecosystem for the public to appreciate nature. Due to the fire prone grassland of Citadel, there are regular fires which sweep much of the area every year.Fire breaks are created by adding a barrier made of rocks around each plant and  regular removal of grass. Herbicides are used in controlling the alien plants at Petrin which are highly dense. Adapted Native species, prevailing to the environmental conditions of the site, were selected to reduce mortality risk. After a ground cover is established and some of the pioneer species start growing, species that need more humidity and shade will be planted.Endangered ecosystem will regenerate through seed dispersal.
