Mizoram has the third highest total forest cover with 15,94,000 hectares (39,40,000 acres), and highest percentage area (90.68%) covered by forests, among the states of India, according to 2011 Forest Survey of India. Tropical semi-evergreen, tropical moist deciduous, subtropical broadleaved hill and subtropical pine forests are the most common vegetation types found in Mizoram. Bamboo is common in the state, typically intermixed with other forest vegetation; about 9,245 km2 (44%) of the state's area is bamboo bearing. The state and central governments of India have cooperated to reserve and protect 67% of the land covered by forests, and additional 15% by management. Only 17% of the land is non-forested area for cultivation, industry, mining, housing and other commercial human activity. Satellite data suggests 91% of state's geographical area is covered by forests.
Jhum cultivation, or slash-and-burn practice, was a historic tradition in Mizoram and a threat to its forest cover. This practice has reduced in recent decades, due to a government-supported initiative to support horticultural crops such as pineapple and banana plantations.
