Abstract:
... Forest inventory data are widely used for broad-scale quantification of forest carbon budgets. Such data usually represent forest wood volume (m3 ha−1), which needs to be converted to biomass carbon value (Mg C ha−1) for carbon stock estimates. Our main objective is to estimate the carbon stock for all sugi (Cryptomeria japonica D. Don) and hinoki (Chamaecyparis obtusa Endl.) plantations in Japan ...

Abstract:
... Based on an empirical study of the forest practise at Lauenburgische Kreisforsten in Northern Germany an economic analysis of near-natural beech stand management is performed. The profitability, cash flow and economic flexibility of near-natural management (NNM) is compared to that of converting to: (i) Norway spruce, (ii) a clear felling beech regime with a rotation of 120 years (CF) and (iii) a ...

Effect of symbiotic association of actinorrhiza (Frankia) and arbuscular mycorrhiza on the seedling growth of host Coriaria nepalensis, and its facilitative effect on two important non-host seral tree species, i.e. oak (Quercus leucotrichophora) and pine (Pinus roxburghii) was studied. C. nepalensis showed dual symbiosis of actinorrhiza and arbuscular mycorrhiza. There was a significant increase i ...

We investigated causes of this patchiness in selectively logged forests near the Danum Valley Field Centre (DVFC) in Sabah, Malaysia. In a recently logged forest, we compared seed sources and seedling establishment between two logging systems (conventional practices [CL] and reduced impact logging [RIL]) and between ...

Abstract:
... An 11-year study of total seed and seed production in five natural Japanese beech (Fagus crenata) forests in Hokkaido, northern Japan, estimated the spatial synchrony of masting and examined whether variation in annual total seed production resulted in fluctuations in pre-dispersal seed-predator populations. We found less synchrony in total seed production than in sound seed production among sites ...

We manipulated soil compaction and moisture to evaluate the effect of soil physi ...
