For large areas, the planting of just one or two species of trees should be avoided. Instead, a mixture of a variety of tree species would help create a more stable environment. "Many are interested in planting forest tree species in their garden without realising that these trees will cause maintenance problems like uncontrolled growth or trees that can damage public amenities,” he said in a statement. The 100 Million Tree-Planting Campaign 2021-2025 was launched in January and was part of the Greening Malaysia programme. He said that among the natural habitats found in the country included hill dipterocarp forest, upper hill dipterocarp forest, mountain oak forest, mountain ericaceous forest, marine swamp forest, peat swamp forest, freshwater swamp forest, riparian edge forest, coastal forest, swamp forest and limestone forest.
