During the thesaphiban administrative reforms the district was created in 1895 with the name Bia Sad. On 22 March 1903 it was renamed Pak Phanang, a name first recorded for the area in 1665. On 25 October 1962 Tropical Storm Harriet hit the district. The low Talumphuk peninsula to the north of the district was completely devastated, and even in the town Pak Phanang itself the storm surge made the water rise four metres. The flooding caused more than 1,000 fatalities and many more homeless.
Geography
Neighboring districts are : Hua Sai, Chian Yai, Chaloem Phra Kiat and Mueang Nakhon Si Thammarat. To the east is the Gulf of Thailand. The most striking geographical feature is the long elongated peninsula Talumphuk, which is formed of sand deposited by the predominantly northward current interacting with the outflow of the Pak Phanang River. The shallow bay formed by the peninsula is about 3 km wide at the mouth of the riverand 10 km at the top of the peninsula. Originally the coastline of the bay consisted of tidal flats and mangrove forests, however a lot of the western coast had been converted into shrimp farms.
Economy
"Bird's nest condos" are said to dominate the skyline of the district. The purpose-built buildings were constructed to encourage nest building by edible-nest swiftlets when the price of edible bird's nests boomed following the 1997 Asian financial crisis. Pak Phanang has more than 500 farm buildings and each can generate income of around 50 million baht per year. the export price of farmed nests is around 80,000 baht per kilo. Exported to China, the price doubles, selling for up to 160,000 baht per kilo. In Thailand, the number of nests extracted from caves is roughly 300 tonnes per year compared with just 100 tonnes from buildings, largely attributable to artificial birdhouses being illegal in Thailand. The business is "grey" and "underground".
Administration
The district is divided into 18 sub-districts, which are further subdivided into 133 villages. Pak Phanang is a town which includes tambon Pak Phanang and parts of tambon Hu Long, Pak Phanang Fang Tawan Tok, Pak Phanang Fang Tawan Ok, and Bang Phra. There are a further 17 tambon administrative organizations.
