Data Base

The Experimental Forests accumulate a wide range of research and observation data and publicize them as database for research and education. The data includes census on timbers, measurements of environmental conditions and general data of flora and fauna; long-term monitoring and concurrent observation at multiple Experimental Forests are practised. The database is stored at the public database manager by JaLTER (Japan Long Term Ecological Research Network), and the data can be viewed and downloaded on the Internet with compliance to the data release policy by JaLTER.
