Forests in boreal and temperate forest-ecosystems have importance for carbon balance since they sequester large amount of atmospheric carbon by uptake of carbon-dioxide during photosynthesis, and transfer and store carbon in the forest ecosystem. Forest material can be used for bio-fuel purposes and substitute fossil fuels, and supply wood products, which can replace carbon-and-energy-intensive...

Reducing carbon emissions from deforestation and degradation in developing countries is of central importance in efforts to combat climate change. Key scientific challenges must be addressed to prevent any policy roadblocks. Foremost among the challenges is quantifying nations’ carbon emissions from deforestation and forest degradation, which requires information on forest clearing and carbon s...

Accurate estimation of forest biomass C stock is essential to understand carbon cycles. However, current estimates of Chinese forest biomass are mostly based on inventory-based timber volumes and empirical conversion factors at the provincial scale, which could introduce large uncertainties in forest biomass estimation. Here we provide a data-driven estimate of Chinese forest aboveground biomas...

Longleaf pine is a highly desirable species, resisting fire, insects and pathogens, and produces quality solid-wood products, but regeneration of the species has been difficult. Natural regeneration is feasible only on a small portion of the area considered to be longleaf pine type. Therefore, artificial regeneration must become a reliable means of regenerating the species if restoration of the...

Converting secondary natural forests (SFs) to Chinese fir plantations (CFPs) represents one of the most important (8.9 million ha) land use changes in subtropical China. This study estimated both biomass and soil C stocks in a SF and a CFP that was converted from a SF, to quantify the effects of land use change on ecosystem C stock. After the forest conversion, biomass C in the CFP (73 Mg ̈ha ́1)...

Methods for the control of wandering Jew (Tradescantia fluminensis) are reviewed and one selected to eradicate this weed from a forest remnant near the lower Rangitikei River. The botanical importance of the forest is assessed in the context of Manawatu Plains Ecological District. Its future conservation management is related to other problem weeds, notably Cobaea scandens, Solanum jasminoides,...

Much of the world’s gene pool is located in tropical rainforests, which are being destroyed at an alarming rate. Proper management of protected forests is crucial to avoid further loss of biodiversity. Resource extraction by local communities can be a major obstacle in the management of protected forests. This paper develops a two sector dynamic model for agriculture and forest resource extract...

Deforestation often results in massive carbon emissions and loss of ecosystem services. The objective of this paper is to develop an integrated approach to quantitatively derive changes in forest carbon stock and changes in the economic value of forest carbon due to deforestation. Combining the best available remote sensing and socioeconomic datasets, this approach establishes a comprehensive b...
