- Abstract:
- ... Bark stripping by Asiatic black bears (Ursus thibetanus) has a serious impact on conifer plantations in Japan, resulting in physical damage to the tree trunks and reduction of the value of the timber. The aim of this study was to clarify whether these plantations are more prone to damage by bears at particular times and sites, to more effectively prevent this damaging behavior. The study was condu ...

- Abstract:
- ... This study evaluated the effect of light intensity on monoterpene emission from the three dominant coniferous tree species in Japan (Cryptomeria japonica, Chamaecyparis obtusa and Pinus densiflora). Monoterpene emission experiments were conducted by using a growth chamber where temperature and light intensity can be controlled. In the experiments, air temperature was set at 30 °C and light intensi ...

- Abstract:
- ... This study analyzes the effect of strip thinning on tree transpiration (Et) in a dense and mature Japanese cypress (Chamaecyparis obtusa Endl.) plantation in central Japan. Strip thinning, which removed 50% of stems, was conducted in a headwater basin in October 2011. Xylem sap flow densities (Fd) were measured using thermal dissipation (Granier-type) sensors in a 156-m2 plot before and after thin ...

- Abstract:
- ... Buried trees in the Ubuka Basin, southwestern Japan, were investigated to identify the wood species and to build tree-ring chronologies. A total of 65 trees were collected belonging to three species: Japanese cedar (Cryptomeria japonica, 63 trees), Japanese nutmeg tree (Torreya nucifera, one tree) and Hinoki cypress (Chamaecyparis obtusa, one tree). Crossdating of the individual ring-width series ...

- Abstract:
- ... Generic equations are proposed for stem, branch and foliage biomass of individual trees in even-aged pure stands of Cryptomeria japonica, Chamaecyparis obtusa and Larix kaempferi. Biomass data was collected from a total of 1,016 individual trees from 247 stands throughout Japan, and five regression models were assessed by root mean square error, mean bias, fit index (FI), and AIC. The results show ...
