The area of Monvert was named after Chevallier Antoine de Monvert, and was previously a dense indigenous forest (with "Bois de Natte", "Bois Manioc" and "Manglier vert" being the most commons tree species).
This area was set aside for conservation because of the unusually high biodiversity involving critically endangered species, and the nature park was set up between 2001 and 2006.
