The negative impact of the rusa deer (Cervus timorensis russa) on crops and pastures in New Caledonia was reported as early as 1882, barely twelve years after its introduction to Grande-Terre. The first hunts were organized in 1921. The effects of grazing on the other plant formations, such as the sclerophyll forest of the West Coast of Grande-Terre, were studied in the 1990s, notably during operations of enrichment of the natural forest with kaori (Agathis moreii).
