The huge extents of the softwood plantations in Australia’s national forests (about 1,020,000 hectare in 2009) require continuous silviculture operations. Consequently a reliable and continuous quantification of the plantation structure is needed to sustainably manage them. Remote sensing data is considered as a cost-effective and efficient tool for this task and several remotely sensed dataset...

The first contract laborers arrived from China in 1852, but little attention was paid to their medical needs. In 1886 a physician from Japan arrived to minister to the health and medical needs of the Japanese immigrants. After 1900 most physicians caring for immigrant plantation workers were Western trained from the Mainland. Many advances in medicine were started on plantations such as the sec...

The patterns and drivers of soil microbial communities in forest plantations remain inadequate although they have been extensively studied in natural forest and grassland ecosystems. In this study, using data from 12 subtropical plantation sites, we found that the overstory tree biomass and tree cover increased with increasing plantation age. However, there was a decline in the aboveground biom...

The aim of this study was to assess the impact of forest age and season on the soil microbial community and enzyme activities in sea-buckthorn plantation system and to determine the relative contributions to soil microbial properties. Soil sampling was carried out in the dry season (April) and wet season (September) in four areas, including: abandoned farmland (NH), an 8-year- old plantation (y...

A large area of plantations has been established worldwide and especially in China. Evaluating the restoration status of these plantations is essential for their long-term management. Based on our previous work, we used an ecological memory (EM) approach to evaluate four 26-year-old plantations that represent four common kinds of plantations in subtropical China, i.e., mixed broad-leaved planta...

Wireless sensor network is a popular technology on information acquisition and processing, which has been widely used in plantation ecological monitoring domain. The plantation environments, including antenna height-gain, depolarization, terrain, humidity and many factors have great influences on the propagation of 2.4GHz wireless sensor network radio frequency signal. In this paper, a complete...

The extension of urban perimeter markedly cuts available productive land. Hence, studies in urban sprawl analysis and modeling play an important role to ensure sustainable urban development. The urbanization pattern of the Greater Asmara Area (GAA), the capital of Eritrea, was studied. Satellite images and geospatial tools were employed to analyze the spatiotemporal urban landuse changes. Objec...
