Myanmar does not have adequate data to assess primary forest cover, so the country has used the same figure since 1990 (Figure 3). Thailand and Viet Nam have reported the largest increases and together account for 85 percent of all planted forest in GMS countries. For Myanmar, planted forest, which showed an increase from 1990 to 2010, declined during 2010 to 2015, while for Cambodia it remained constant, although due to the relatively very small area it is hard to see in Figure 3.
