Results of Study on Vegetation Diversity at Muong Nhe Nature Reserve, Dien Bien Province

Abstract

The vegetation at Muong Nhe nature reserve has been described in 5 types: Tropical
evergreen moist monsoon closed forest (only secondary sub-types formed by human activities);
Tropical semi-evergreen semi-dry monsoon closed forest; Sub-tropical evergreen moist monsoon
closed forest (including secondary sub-types formed by human activities); Sub-tropical evergreen
moist monsoon broad-leaved mixed with conifers forest; Sub-tropical semi-dry monsoon deciduous
forest (only secondary sub-types formed by human activities) and cultivated plant communities. The
results showed that the closed forest is only located at sub-tropical zone. Based on species existed in
each forest sub-type or community, the abundant species in tropical zone are fast-growing and
photophilic plants while the abundant species in sub-tropical zone include both fast-growing plants
and typical sub-tropical plants with monsoon moi climate or monsoon semi-dry climate. In the winter,
the tropical semi-evergreen forest and sub-tropical deciduous forest can enlarge their colony to the
north-western part. The non fast-growing and photophilic species are expected to be most abundant in
the future based on currently vegetation succession indication, and there will be increasingly more
closed forests in the near future at Muong Nhe nature reserve.
