Southwest Pacific Islands Collection
Southwest Pacific Islands soils have a very high mineral content, in particular New Caledonia. Because of this, New Caledonia has been mined extensively. As a result, much of its native flora is under threat. The flora of Southwest Pacific has adapted to the high mineral content in the soils over the years. This has contributed to the high levels of endemic flora in the region.
Australia and Southwest Pacific Islands share many of the same genera of plants. These include Melaleuca, Grevillea and Araucaria. Southwest Pacific Islands holds half of the world’s species of Araucaria. There are seven species of Araucaria in the collection. Another four are situated around the gardens.
