The vegetation of the Western Domain now consists of discontinuous patches of deciduous dry forests on the coastal plains and limestone plateaus, ranging from sea level to 800 m. It covers the area from Antsiranana in the north to Morombe in the southwest. Annual rainfall ranges from 500-2.000 mm, being lightest in the south and heaviest in the north. There is a marked dry season of almost seven months during which many trees of the canopy layer shed their leaves. The shrub layer is well developed and vines are common.
