The other significant band operates throughout latitudes in the southern hemisphere and incorporates the forests of South The us, Central Africa and Asia. These are tropical forests and are not all rainforests, as some of them are at higher altitudes or by the coast exactly where they kind mangrove forests. Mangroves are notably crucial. They are tidal forests and have critical features as natural sea defences, breeding grounds for fish, and habitats for heaps of other species.
