The database provides 177 plant traits of Cryptomeria japonica (sugi) and Chamaecyparis obtusa (hinoki) from 364 primary sources published since 1950. The compiled traits include physiological, morphological, anatomical, and biochemical features.

ForestGEN provides EST (Expressed Sequenced Tag) and genome information oncreatures living in forests, including trees, microbes such as fungi,mushrooms and nematodes, and insects.
ESTs in the database have been clustered and assembled, and are provided aslong consensus sequences. You can perform search in the database withkeywords (protein names) or homologous sequence.

FFPRI FluxNet Database provides half-hourly observational data of carbon dioxide absorption by forest ecosystem and related micrometeorological information. These data have been obtained by the long term flux observation using eddy covariance method which are carried out in 5 research sites (6 sites until 2002) with different forest types and climates in Japan.

Forestry and Forest Products Research Institute is continuing to monitor the water balance in five forested areas of Japan to clarify the relationship between forest conditions and water balance. Forest Experimental Watershed Database (FWDB) provides the observation data already published in print as electronic files.

Longicorn beetles are often used in biodiversity studies of forests because they mostly depend on woody plants for food and habitat. This database covers about 90% of Japanese longicorn species, providing dorsal, lateral, and frontal views of the specimens deposited at FFPRI.

This database provides images of specimens of more than 400 longicorn species collected in East Kalimantan, Indonesia.

The PRDB is a database of vegetation survey (relevé) conducted throughout Japan using the phytosociological method. Relevé data in the PRDB consists of the location (geographic mesh code), elevation, topography and other site information, hierarchical structure, species name and dominance of the vegetation, etc. Maps of plant distribution created using the PRDB are available on the website.

Trap-nesting bees and wasps are those aculeate species that preferentially nest in tube-like structures. Their diversity and abundance often indicate conditions of various natural environments including forests. You can find common trap-nesting species of Japan in this site, with images of adult specimens and of nests.
