Species composition and turnover in a series of' permanent sample plots established during the 1930s and 1940s in Budongo, a semi-deciduous Ugandan forest, are reported. The plots were established as part of' a sequence first used to describe forest succession, five of' which have been maintained...

A qualitative evaluation of a ‘sangre de grado’ tree population along the Aguaytia watershed determined its abundance and latex production potential. Also, the flora species composition of the 9 year-old secondary forests was outlined. By collecting botanic samples, the species Croton draconoides...

Although forest tree pattern-dynamics has long been a focus for ecological theory, many aspects of basic analysis remain problematic.This paper describes, examines and illustrates an 'extreme-value' approach to clump detection. Simulations demonstrate that the approach, though simple, is sensitiv...

Biomass of a mature man-made forest in West Java, Indonesia, was estimated to evaluate the carbon sequestration potential of plantation forest in the humid tropics. Twenty plots, each 0.25 ha in area and containing one to six planted species over 40 years of age and with closed canopies, were sel...

A set of Permanent Sample Plots (PSP) was established in the lowland mixed dipetrocarp forest within PT Inhutani II concession at Malinau (2o45’ – 3o15’N, 116o30’), East Kalimantan (Figure 1). They were designed for comparative studies of conventional logging (CNV) and reduced-impact logging (RIL...

Input/output data from tree growing experiments in Southeast Asia were analysed within the framework of a model of a smallholder farm. Data on cropping were obtained from surveys of farmers. Prior to formulating a whole farm model, this input/output data were modified in two ways: (a) a yield pen...

Selective logging applied in tropical forests is based on one universal criterion: a minimum diameter cutting limit for all commercial timber species. Minimum diameter cutting limits in mixed dipterocarp forests of the Malesia region lead to high felling intensities (10–20+ trees per hectare). Su...

The aim of this paper is to (1) identify floristic regions in the lowland (below 500 m a.s.l.) tropical dipterocarp rain forest of Borneo based on tree genera, (2) determine the characteristic taxa of these regions, (3) study tree diversity patterns within Borneo, and (4) relate the floristic and...

Permanent sample plots (PSP) are an important tool in monitoring forest dynamics and change. In Malinau Research Forest, East Kalimantan, 24 PSPs of 1 ha each were established and all trees with dbh = 20 cm were identified and their diameters were measured in 1998 prior to logging operations and ...
