Total amounts in DDF varied from 54.06 to 78.57 Mg ha-1, while MDF had higher, 139.82 to 152.92 Mg ha-1. In DDF, percentages of carbon in plant were 60.0 to 77.3%, while MDF had 57.10 to 65.79%. In soil, DDF had values of 22.70 to 40.0%, while MDF had 34.10 to 42.90%. The higher percentages of carbon storage in plant were observed in forest with poor soil, but the storages in plant and soil were nearly the same for forest that had deep fertile soils.

Research application and relevance to sustainable development goals This research was taken in a restored watershed managed by HHKRDS Center to assess conditions of plant species diversity and carbon storages in two deciduous forests. The forests have recovered from 1984, the beginning of Center establishment. Carbon storages in forests are increasing year by year with plant growth. It is useful data as a guideline for management and study of community forests in the north. The watershed increases potential of water supply to streams which is useful for agriculture in lower land areas as well as providing non-wood forest products for food and sufficient economic livelihoods of villagers. Thus this conservation of forest biodiversity is relevant to the sustainable development goals.
