Forest loss is one of the most pervasive land surface transformations on Earth, with drastic effects on global climate, ecosystems, and human well-being. As part of biodiversity conservation and climate change mitigation efforts, many countries, including China, have been implementing large-scale policies to conserve and restore forests. However, little is known about the effectiveness of these...

Invasive species have a wide range of effects on soils and their inhabitants. By altering soils, through their direct effects on native soil organisms (including plants), and by their interaction with the aboveground environment, invasive soil organisms can have dramatic effects on the environment, the economy and human health. The most widely recognized effects include damage to human health a...

As one of the most important renewable and sustainable energy sources, the forest biomass energy resource has always been the focus of attention of scholars and policy makers. However, its potential is still uncertain in China, especially with respect to its spatial distribution. In this paper, the quantity and distribution of Chinese forest biomass energy resources are explored based mainly on...

Balancing forest harvesting and restoration is critical for forest ecosystem management. In this study, we used LANDIS, a spatially explicit forest landscape model, to evaluate the effects of 21 alternative forest management initiatives which were drafted for forests in the upstream region of the Hun River in northeastern China. These management initiatives included a wide range of planting and...

Rising wildfire suppression expetizditures on public land in the United States have led to increased scrutiny of wildfifne managemefzt practices. One area that has received particular attention is the Forest Service's increasing reliance on contract fire crews. Because a contract crew rate includes several costs that are not included in the wage costs of a Forest Service crew, it is difsicult t...

This paper demonstrates how the Nation of Islam (NOI), a well known black nationalist organization, is utilizing notions of community to promote the activities and goals of its farm to other black people. The NOI ownsMuhammad Farms in rural southern Georgia, USA. Its stated purpose is to feed all black people in the United States. Historically, theNOI has occupied a radical space in the black c...

gauge instrument or prism was introduced, which significantly expedited the process. There was no national forest resource information in China during 1963–1972. The first NFI was performed during 1973–1976, in which a stratified systematic sampling technique was used to locate NFI sample plots. Each province, autonomous region, or municipal city designed one or more sampling populations accord...
