Mathematical proofs show that rate estimates, for example of mortality and recruitment, will decrease with increasing census interval when obtained from censuses of non-homogeneous populations. This census interval effect could be confounding or perhaps even driving conclusions from comparative s...

The area of forest plantations in the tropics worldwide is increasing as a response to the expansion of degraded lands. Rural farmers of many regions of the dry and humid areas are responding to government and other incentives, dedicating portions of their land to native and exotic tree plantatio...

Over the last ten years there has been an increasing emphasis on development of plantation estates for both wood fiber and agricultural crops such as oil palm. The principles for sustainable development and establishment of industrial plantations also account for the social, environmental and bio...

Studies predicting diameter at breast height (dbh) from stump height measurements are numerous but none had been conducted in Malinau distric, East Kalimantan. The objective of this study is to develop a relationship between stump height and dbh in order to predict dbh from diameter at estimated ...

Exotic tree species predominate in reforestation in tropical regions worldwide. However, some native species are suitable for plantations, providing a wider variety of products. Adequate government programs of incentives, coupled with good technical advice to farmers, are needed to stimulate refo...
