Fraser Island – Rainforest

The last time I went to Fraser Island, the first stop was to visit the tropical rainforest, the only tropical rainforest in the world that grows on a sand island. However, some trees, such as the white gum trees, seem out of place and grow in rows. It turned out that those were not native, and people tried to plant them on the mainland of Australia. Before, there was a logging industry on the island, so the government introduced different kinds of trees to rebuild the forest and see if it could prevent wildfires. However, the tour guide said that it was not very successful. This is a historic rainforest where new species are introduced at will, and if they are lucky, the new species and old species may be done well. Thus, you can increase biodiversity. However, it can cause ecological imbalance under bad conditions, and even the original species will be wiped out.
