When the goal of natural forest management is to maintain the biodiversity and ecological integrity of the forest while harvesting timber, the silvicultural systems employed must promote timber production and reduce negative impacts on whole timber resources. To foster development of such a syste...

Hunting of wildlife in Central Africa is largely considered to be unsustainable. Several studies indicate that most mammal species should already have disappeared from many Central African forests but markets continue to be supplied with bushmeat, with no sign of large scale extinction of the mos...

Investigations were conducted into the development characteristics and influence of stage of pod development on seed viability of Gliricidia sepium. The influence of sowing depth on seedling emergence of the first and last harvests was also investigated. Pods were harvested over three periods - 5...

In East Kalimantan (Indonesia), impacts of conventional and reduced-impact logging (RIL) on forest ecosystems were compared on the basis of pre- and post-harvesting stand inventories. There was a positive and significant correlation between the proportion of trees damaged by felling and the densi...

Timber harvesting was investigated both in terms of commercial timber volume extracted and impact on residual stand. Conventional (CNV) and reduced impact logging (RIL) techniques were compared on the basis of pre- and post-harvesting stand inventories. The timber volume extracted averaged 87 m3 ...

Although the majority of soils in Africa are P deficient, the high cost of conventional water-soluble P fertilizers limits their use by resource-poor farmers. Rockphosphates are a low-cost alternative. The effect of Egyptian rockphosphate (ERP) from two sources, applied at 50 kg P ha-1, on annual...
