In 1945, 61 percent of Thailand was covered by forest. This percentage dropped to 34 percent and currently about 28.4 percent of Thailand is covered by forest.
From 1990 to 2000 the rate of deforestation has been estimated at about 0.72 percent. From 2000 to 2005 deforestation had reduced to about 0.4 percent per annum.
The main driver of deforestation in Thailand is the rapid increase in population. This increase is most evident in the north eastern region where the forest is cleared for farming to feed the nation’s growing population.
The Government of Thailand has encouraged reforestation programs and had put in place a ban on all commercial logging in 1989.
