Invasive alien species are major drivers of habitat degradation, particularly on islands. For example, in Mauritius, the mechanisms by which invasive plants may affect native plants include direct competition, interference with plant–animal interactions, alteration of habitats, and hybridization. Invasive plants are known to substantially reduce flower, fruit and seed production of our native forests. Habitat restoration by controlling alien plants can thus increase growth rate, flowering and fruiting of native trees, leading to increased native tree regeneration and species richness. Native habitat restoration is thus expected to improve foraging habitat quality for native frugivores, thereby providing easier access to food resources within native habitats. This would in turn reduce damage on commercial fruit trees by fruit bats.
