Abstract:

This article analysed the 25–30 years of growth of dipterocarps forests that were logged under the Selective Management System (SMS) at three sites in Peninsular Malaysia to understand how management regimes affected forest stem density and basal area. The management regimes were (1) unlogged, (2) moderately logged forests that logged all dipterocarps ≥ 65 cm diameter at breast height (dbh) and all non-dipterocarps ≥ 60 cm dbh, and (3) intensely logged forests that logged all dipterocarps ≥ 50 cm dbh and non-dipterocarps ≥ 45 cm dbh. The intensely logged regime is similar to the SMS practices

Abstract:

Abstract Based on the reality of production forest management so far, logged-over forest improvement activities generally have received less attention, giving rise to the notion that the management of logged-over areas is not being taken seriously. In general, regeneration and maintenance of remaining stands as a component of the silvicultural system has not been carried out. Silviculturists must address these developments and respond to rapidly changing expectations and global paradigm shifts in how forests are viewed. Silviculturists are challenged to develop silvicultural practices, includi

However, no study has quantified the biodiversity of repeatedly logged forests.

Abstract:

We studied the response of beaver (Castor canadensis Kuhl), moose (Alces alces L.), and snowshoe hare (Lepus americanus Erxl.) to clear-cutting in three blocks that had been logged 10 years ago. In a previous study, these species had been surveyed in the same blocks 2 years before and 2 years after logging. We also surveyed an uncut block of the initial experimental design that was logged more recently. Over the 10-year period, the shrub layer and available browse have improved markedly in clear-cut areas. As compared with logged coniferous stands, logged mixed stands had higher lateral cover

Abstract:

Logged-over natural forest has a different stand structure and composition from primary natural forest due to logging activities. This study aimed to examine forest dynamics (upgrowth, ingrowth, and mortality) of the logged-over forest in PT. Tunas Timber Lestari (TTL) Papua in both stands with and without treatments. The data used in this study were based on the measurement in the Permanent Measurement Plots (PUP) for ten years. This study grouped data into five diameter classes of 10 cm intervals and three wood species groups (meranti timber, mixed timber, and non-commercial timber). Data an

Calculate potential biomass, carbon, carbon dioxide uptake, and economic value of CO2eq uptake in the Logged area of PT Hutan Mulya using purposive sampling data collection techniques for each plot and non-destructive methods through allometric equations. The highest carbon stock potential is in the tree-level diameter class and the location with the highest carbon stock is in the virgin forest area.

Two treatments of different intensities of logging were compared with an undisturbed (control) forest. Data were collected from permanent sample-plots. The effects of logging on floristic composition were stronger in the more heavily logged treatment. The number of species decreased immediately after logging, but started to increase before the fifth year after logging and was higher at the end of the study period than before logging.

Abstract Selective logging is an extensive land use in the Brazilian Amazon region. The soil–atmosphere fluxes of nitrous oxide (N2O), nitric oxide (NO), methane (CH4), and carbon dioxide (CO2) are studied on two soil types (clay Oxisol and sandy loam Ultisol) over two years (2000–01) in both undisturbed forest and forest recently logged using reduced impact forest management in the Tapajos National Forest, near Santarem, Para, Brazil. In undisturbed forest, annual soil–atmosphere fluxes of N2O (mean ± standard error) were 7.9 ± 0.7 and 7.0 ± 0.6 ng N cm−2 h−1 for the Oxisol and 1.7 ± 0.1 and

Abstract:

Logging history and population structure of the dry forest tree species Guaiacum coulteri are described for Oaxaca, Mexico. We propose that the species has been adversely affected by selective logging, with large individuals now being uncommon. We argue that the species is likely to have undergone similar changes elsewhere in its range and, following IUCN guidelines, propose that it is categorized as Endangered. Maintenance of G. coulteri as an understorey shrub may be possible given current land use practices in the area but recovery of populations of large individuals may be more difficult.

The rainfall interception losses were quantified for one hectare each of unlogged and logged humid tropical rainforests. The results show that interception loss is higher in the unlogged forest (11% of total gross rainfall) than in the logged forest (6%). Interception loss was also simulated by the modified Rutter model and Gash's original and revised models. Both the Rutter and revi

Over 10 years ago, Oryx published initial details of an investigation into the effects of selective timber logging on primates in the Sungai Tekam Forestry Concession in peninsular Malaysia (Johns, 1983). This original 2-year field study developed into a long-term monitoring programme, in which the recovery of primates in the regenerating forest is to be recorded throughout the logging cycle. This is the only such monitoring programme so far established in the world's tropical forests. The dataset is now complete for forests logged up to 18 years ago.
