Since the beginning one hundred years ago, forest management in Thailand has undergone many changes, in form of reclassifications, name changes and management changes. All this has resulted in a division of 16 regions with 5 branches in 2002. Five regions in Central-East with 28 national parks, four regions in the South with 39 national parks, four regions in the Northeast with 23 national parks and eight regions in the North with 65 national parks.
