The savannas can be found in all of the regions in Thailand. Some are the result of major geological shifts like earthquakes or volcano eruptions occurring hundreds of thousands years ago, leaving infertile soil with very little vegetation. This type of forest is also the result of deforestation for agriculture. The mobile plantation results in the dried, infertile soil so the grasses grow over the land and dry season wildfires are common. The fires generally extend close to the tree line causing the grassland to expand every year. The savannas are characterized by grass and trees that are fire resistant. Yet, some useful herbs can be found even in these zones, such as Cotton wool grass, Thorn apple, Devil weed, Tio khon and bolete mushrooms. Each year, increasing in savannas means more deforestation, a serious threat that must be reversed immediately through forest and animal conservation.
