Causes for 2025 are estimates, based on what caused forest loss in the same places up to 2024.

- Forest in 2000

- −116 haless forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Hua Hin shrank from about 4,160 hectares to 4,040 hectares, a net loss of about 116 hectares (−2.8%). New forest grew on about 393 hectares, but 509 hectares were lost.
These 2000 and 2020 maps, from the University of Maryland, count any land with trees taller than 5 m as forest, including plantations and orchards. Forest that was cut or burned and had grown back by 2020 counts in both years, so the loss here is smaller than the yearly figures.
These figures cover everything within 10 km of the city center, a wider area than the report above, because forest is usually lost at a city's edges.
