- Biodiversity Research Group
This research group focuses on trees and other plants, insects and vertebrates in forest ecosystems, covering all levels of biodiversity, including their populations dynamics, genetic diversity, evolution of behavior and life history, relationship between species diversity and ecosystem functions, impact of climate change, and landscape conservations.
- Ecosystem Function Research Group
This research group focuses on ecosystem ecology, biogeochemistry, hydrology and micrometeorology to clarify environmental conservation functions and ecosystem services of forest based on in situ observations and experiments of material cycling, soil, river water quality, climate and hydrological processes in forest ecosystems.
- Regional Resource Management Research Group
This research group focuses on sustainable management of regional forest resources with attention to ecosystem conservation to promote co-existence of forest and human society by investigating various regional resources produced from natural and planted forests and their management practices.
