Flora

In the Mizoram–Manipur–Kachin rain forest, the predominant plant community is semi-evergreen rain forest, which covers the vast majority of the ecoregion's intact area, a total of 36% of the ecoregion. Other plant communities include tropical wet evergreen forest (5% of the ecoregion's total area), tropical moist deciduous forest (2%), montane wet temperate forest (2%), and subtropical montane forest (1%). 19% of the ecoregion's area has been cleared, primarily for agriculture and grazing, and 34% of the ecoregion consists of degraded areas.
The semi-evergreen rain forest is dominated by trees of the
dipterocarp family, including ''
Dipterocarpus alatus'', ''
D. turbinatus'', ''
D. griffithii'', ''
Parashorea stellata'', ''
Hopea odorata'', ''
