Model evaluation should include qualitative as well as quantitative examinations of the model. The qualitative parts should comprise a critical appraisal of model logic as well as theoretical and biological realism of the model. The quantitative parts should comprise statistical tests and compari...

Use-values have been advocated as a tool to compare the value of not just individual species, but also of plant families and forest types to local people, e.g. to identify species or habitats in need of special management or conservation. We estimated use-values in three forest types (upper resti...

TROPIS, the Tree Growth and Permanent Plot Information System, contains five elements: (1) a network of people willing to share permanent plot data and tree growth information (serviced by newsletters and information sources hosted at http://www.cifor.id/tropis or available form CIFOR), (2) an in...

A catalogue of ideas for graphical analyses of growth data is presented, in the hope of stimulating the more imaginative analyses. Graphs can be particularly revealing, because the human eye is good at detecting patterns. Suggestions are given to make graphs more effective, and analyses more insi...

Natural forests in the humid tropics differ from temperate and plantation forests in several ways: there may be many tree species; many of these may occur infrequently; there may be a large range of tree sizes and shapes present; tree ages may be unknown and indeterminate; and despite the luxuria...

A new method is proposed for estimating vitality or growth potential for saplings of Scots pine (Pinus sylvestris L.), based on height, diameter and height increment. A two-stage process was used to establish the vitality index. The logarithms of height, diameter and height increment were regress...

Policy issues are central to natural resource management, but the consequences of well-intended policies are not always obvious, especially for land use in frontier areas. A model is proposed to predict the behaviour of individuals in forest communities near the forest frontier, and the resulting...

Sustainability in the context of development and forest management is a concept defined by human-beings. As human needs change across space and time, so will the expectations of what benefits and services of forests need to be sustained. Much of CIFOR's research focuses on providing a better unde...

Ten papers from the full proceedings of the above conference providing results of more complete work on the diverse aspects of regeneration and early growth. The conference discussed the theme broadly and encompassed theoretical and applied aspects, plantation and 'close-to-nature' silviculture, ...
