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 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

Peat swamp forests are highly significant globally, both for their diverse and threatened species and as a representative of unique wetland ecosystems. Apart from its critical role in providing habitat for wildlife, the tropical peat swamp forest also acts as a gene bank that harbors potentially useful varieties of plant species.

Peat swamp forest is a particularly stable ecosystem. This stability may regulate well-balanced water to maintain the existence of typical flora and fauna. The present study describes the structure and species composition from three different sites namely newly logged-over swamp forest, three years old logged-over swamp forest, and four years old-logged over swamp forest in Bengkalis, Riau, Indonesia. The study sites were predominated by four structural ensembles with their strata order from the highest to lowest: emergent trees, canopy, lower ensembles, and undergrowth. The emergent trees con

Southeast Asia is a hotspot of imperilled biodiversity, owing to extensive logging and forest conversion to oil palm agriculture. The degraded forests that remain after multiple rounds of intensive logging are often assumed to be of little conservation value; consequently, there has been no concerted effort to prevent them from being converted to oil palm. However, no study has quantified the biodiversity of repeatedly logged forests. We compare the species richness and composition of birds and dung beetles within unlogged (primary), once-logged and twice-logged forests in Sabah, Borneo. Loggi

Single selective cutting is the most common form of timber extraction in natural forest in the tropics. Although, vast tracts natural forests are already logged-over, the effect of logging on the structure and species composition has been sparsely documented, especially for merbau (Intsia bijuga). Merbau is an excellent timber species and intensively harvested in Papua. The objective of this study was to analyze the structure and

South East Asia is widely regarded as a centre of threatened biodiversity owing to extensive logging and forest conversion to agriculture. In particular, forests degraded by repeated rounds of intensive logging are viewed as having little conservation value and are afforded meagre protection from conversion to oil palm. Here, we determine the biological value of such heavily degraded forests by comparing leaf-litter ant communities in unlogged (natural) and twice-logged forests in Sabah, Borneo.

Despite the widespread use and strong promotion of the sustainable forest management approach, there are still uncertainties about the actual contribution of current forest management practices to sustainability. We studied the problem of sustainable timber production in four tropical countries (Belize, Guyana, Suriname, and Trinidad and Tobago). Data assessed on experimental plots covering 10 km2 were used to compare management practices of four forest tenure types that commonly exist in the study countries: large scale concessions (LSC), private forests (PR), periodic block system forests (P

Upland rice has been cultivated by intercropping patterns on the logged area of the teak forest in Java Island for a long time. However, the activities of upland rice farming are still subsistence and not profit-oriented. This study aims to determine the feasibility of upland rice farming on the logged area of teak forests based on farming productivity. Data was collected using a survey and interview to 30 farmers who cultivated upland rice on the logged area of Perhutani teak forest.

Understanding how tropical forest structure and function change during the decades after logging is a key research challenge. This thesis reports functional traits, forest structure, biomass, net primary productivity (NPP) and allocation, as well as their controlling factors in an old-growth forest and a 54-year-old logged-over forest in Ghana. By analyzing root traits, I found fine-root biomass, root length, surface area, and root tissue density were higher in the logged-over forest, whereas the old-growth forest had higher specific root length and specific root area.

Over the past 200 years, most of the forestland growing in the eastern United States has at one time been logged for timber, cultivated for agriculture, or developed into urban and suburban spaces. Though millions of wooded acres still exist in national forests, parks, and preserves, very little of that land should be considered undisturbed or old-growth. Given these realities, it may be surprising to learn that pockets of old trees, or groves, still survive near American suburbs.
