Defoliants had destroyed around 7,700 square miles of forests, estimating to be around 6% of the total land in Vietnam. The effects of Agent Orange persisted after the war, and lead to Vietnam's forest cover declining by 50% in the years during the war and after, reaching an all-time low for forest cover in the 80's and 90's.

Vietnam’s forest recovery is a notable success story, with forest cover increasing in recent decades after a period of extreme deforestation.
