The Chao Phraya basin is home to about half a dozen endemic dragonflies and damselflies . The conservation status of most of these in unclear (they are rated as data deficient by the IUCN ), but Cryptophaea saukra

782-463: The water quality of major rivers flowing into the upper Gulf of Thailand has seriously deteriorated, and the lower Chao Phraya contains bacteria and nutrient pollution from phosphates , phosphorus , and nitrogen . Nutrient pollution causes algae to grow faster than ecosystems can handle, harming water quality, food resources for aquatic animals, and marine habitats. It also decreases the oxygen that fish need to survive. PCD rated water quality at

Saraburi has a tropical savanna climate, Aw (Climate Classification system of Koppen) The climate is arid with little rain in winter, relatively high temperatures in summer, cool in winter, and rain from May to October, about 70–90 days. The average annual temperature

966-464: The aim of mobilizing citizens during times of war. From the Ayutthaya period, the story of Saraburi is usually related to battles and wars. As for the origin of the word "Saraburi", it is thought that due to its location near a swamp called "Bueng Nong Ngong", when the town was established a combination of sa ('swamp') and buri ('town') was suggested and the town was named "Saraburi". Lopburi and Nakhon Nayok were combined to set up Saraburi Province with

1058-620: The aquatic fauna of Chao Phraya and Mae Klong show clear similarities, and they are sometimes combined in a single ecoregion with 328 fish species. Despite their similarities, there are also differences between the aquatic fauna of Chao Phraya and Mae Klong; the latter (but not the former) is home to a few taxa otherwise only known in major Burmese rivers: the Irrawaddy , Salween , and Tenasserim . The aquatic fauna in Chao Phraya–Mae Klong also show clear similarities with that of

The critically endangered red-tailed black shark , a small colourful cyprinid that is endemic to Chao Phraya, is commonly seen in the aquarium trade where it is bred in large numbers, but the only remaining wild population

1196-480: The fish species known from the Chao Phraya–Mae Klong, only about 50 are absent from the Mekong. There has been extensive habitat destruction (pollution, dams , and drainage for irrigation ) in the Chao Phraya basin and overfishing also presents a problem. Within mainland Southeast Asia , the only freshwater region with similar high levels of threat is the lower Mekong. It has been estimated that only around 30 native fish species still are able to reproduce in

In the low alluvial plain which begins below the Chao Phraya Dam , there are many small canals ( khlong ) which split off from the main river. The khlongs are used for the irrigation of the region's rice paddies. The rough coordinates of the river are 13 N, 100 E. This area has

1380-440: The mainstream of the Chao Phraya River. The catfish Platytropius siamensis is endemic to Chao Phraya and Bang Pakong , but has not been recorded since the 1970s and is considered extinct . Recent records of the near-endemic cyprinid Balantiocheilos ambusticauda are also lacking and it is possibly extinct. Three of the largest freshwater fish in the world are native to the river, but these are all seriously threatened:

Then the mountains that are the natural boundary of the Chao Praya watershed form a divide , which has, to some degree, historically isolated Thailand from other Southeast Asian civilisations. In northern Thailand the divide roughly corresponds to a long section of the political border of the country today. Southern portions of the divide's boundary correspond less to

1748-551: The potential for creating large protected areas to preserve original habitat no longer exists. However much wildlife does remain in the rice fields and steps may be taken to preserve these as urban and industrial development on the plains is ongoing and the Industrial Estate Authority of Thailand has very little control or planning over this. Particular threats come from the conversion of rice paddies to large-scale production of prawns by pumping in seawater, and
