Thale Ban marsh

      Most of the area is a complex mountain landscape and it has a total area of 196 square kilometers. To the east are mountains made up of granite and granodiorite. The soil has relatively high fertility levels and is rich in dense forest vegetation. However, the soil erodes easily due to the high gradients on the western slopes. There is also chemical erosion caused by groundwater that creates trace or large holes, which often turn into caves. The park is home to caves such as Thon Din Cave, and Lot Pu Yu Cave, and the Thale Ban marsh created by a cave collapse. The highest peak in this area, Khao Cheen is about 756 meters above sea level. 

       Characteristics of the waterways around Thale Ban National Park show they are mixed in length but mostly flow east to north, flowing into the Khlong Chaliang and the Duson Irrigation Canal. Tributaries include Klang Ban Canal, Ya Roi Canal and Tu Yo Canal, which is also used for Satun Province’s water supply. Villagers around the park used the streams as a source for agriculture.

The park has a mountain range and plains in the valley bottoms. Therefore, there are many small streams with water flowing during the rainy season.

        The southern part of the National Park, around the marsh,  is in the valley between Khao Wang Kunom, Khao Pu Yu, and Khao Khwon Khuan Bo Nam , and the boundaries to the west. There is a short stream flowing into the sea, with tributaries including Tha Chin Canal and Pu Yu Canal. This creates brackish water in the mangrove swamp forest area along the west coas.

Climate Characteristics

     As Satun is located on the west coast of the southern region bordering Malaysia it is influenced by the monsoons. The southwest monsoon is from from May to October, and the northeast monsoon influences from November to February.

     But because Satun Province is on the west coast and at the end of the wind, the park is therefore rarely influenced by this monsoon wind.

      However, between October and November, it still rains heavily. After this, the rain may begin to decrease accordingly. From December to March, it's the dry season because the northeast monsoon is weakening. And in February, the southeast monsoon comes. This is because the wind blows from a high-pressure area in the South China Sea, which is hot and humid. Therefore, this month the temperature is rising, and during this period, Satun receives less rainfall than at other times of the year.

      The climate statistics in the Thale Ban National Park were collected at the weather station in Satun Province, which is located at latitude 6 degrees 39 minutes north and longitude 100 degrees 05 minutes east. The date was recorded from 1978 - 1990.

The climate has 2 main seasons. Summer is between February and June, when the weather is very hot, especially in April.  The rainy season between August and November and has high relative humidity

General Forest Conditions

      The forest is 90% tropical rain forest, which includes mixed deciduous forest and mangrove swamp forest. There are more than 400 species of wildlife, including more than 60 species of mammals, 304 species of birds, 40 species of reptiles, 20 species of amphibians, and hundreds of aquatic species..

      Satun Province is about 970 kilometers from Bangkok. From the town of Satun, take Route 406 for about 19 kilometers, then turn right onto Highway No. 4184 for about 20 kilometers. That takes you to the National Park Headquarters.
