Abstract
The Crown Forests in Sado Island, since 1889 to 1925, consisted of 420 forest lots with 6,750 ha in the area. As the result of this study to analyze the record of the survey on each stand, 45 tree species including bamboo were recorded in the forest register which was maden about 120 years ago. Important tree species for forestry were recorded in the standard name in the those days, for examples, Cryptomeria japonica (sugi), Pinus densiflora (matsu), Pinus thunbergii (kuromatsu), Quercus serrata and Q. crispula (nara), Castanea crenata (kuri) and Juglans mandshurica var. sachalinensis (kurumi). On the other hand, almost of the less important tree species were recorded by local name, for examples, Abies firma (tsuga), Cornus controversa (kuromizu or mizufusa), Populus sieboldii (dero), Kalopanax septemlobus (hotara, tara), Neolitsea sericea (urajiro) and Machilus thunbergii (tamaki). Therefore, it was guessed that a group consisted of the engineers trained by the central government and the indigenous engeneers, surveyed the forests for the registration.
