“…The logging road is approximately 7 m wide, runs for 7.89 km, and covers about 3% of the area of Block 5. The intensity of logging operations, including road construction, at this study site is markedly lower than in other logged forests in tropical regions (Uhl and Vieira 1989, Pinard et al 2000, Jackson et al 2002. Although open lands produced by logging operations include not only logging roads but also skid trails and log yards, we focused only on the logging roads for the comparison with inner parts of the forest.…”

“…This type of logging contributes substantially to forest degradation. In tropical forests, approximately 12-25% of the forest area is covered by logging roads, skid trails, and log yards (Uhl and Vieira 1989, Pinard et al 2000, Jackson et al 2002. Forest degradation resulting from the excessive construction of logging roads and skid trails substantially reduces the above ground biomass, which affects the soil environment and the forest ecosystem (Sidle et al 2004, Gullison andHardner 1992).…”

The spatial gradient of soil respiration from a logging road to the inner part of a forest, and the major environmental factors controlling soil respiration were studied in a hill dipterocarp forest in Peninsular Malaysia to examine the spatial effects of logging road construction on soil respiration. Soil respiration, soil temperature, and soil water content were measured at six points along a total of twenty-five 35-m transects. The logging road at the study site was constructed in 2009. The soil respiration rate on the logging road was very low (0.376 mol CO 2 m 2 s 1 ), and there were no significant differences between the roadside and inside the forest (4.76-5.95 mol CO 2 m 2 s 1 ). Path analysis showed that the soil respiration rate was affected by soil temperature and distance from the logging road. This finding differs from those of previous studies conducted in lowland tropical rain forests. We speculate that the low soil respiration rate on the road is primarily because of soil compaction and low concentrations of carbon-containing material. The soil temperature at the roadside (which was positively correlated with soil respiration) was higher than inside the forest. Despite the differences in soil temperatures, differences in soil respiration between the roadside and the inner parts of the forest were not significant, probably because of the small amount of litter present as a substrate for microbial respiration at the roadside and/or the occurrence of different microbial communities and biomass between the roadside and the inner parts of the forest.

“…This might be that an open areas may provide suitable habitat and foraging sites for them (Gram et al, 2003;Campbell et al, 2007). Selective forest logging leads to the increase of temperature and decrease relative humidity (Johns, 1988;Jackson et al, 2002). Opening gaps enhance shrub vegetation which frequently bears diverse flowers and fruits which is a major diet of these bird species.…”

Logging activities have encroached into the hill dipterocarp tropical rainforest area since the lowland dipterocarp forests have decreased in size. Hill dipterocarp tropical rainforest is rich in habitat diversity and provide a variety of resources for avian species such as food, habitat and shelter. Therefore it is important to examine the logging effects of hill dipterocarp rainforest on avian species. We compared the avian richness and diversity in different aged post-harvested hill dipterocarp tropical rainforest at the Berkelah Hill Dipterocarp Rainforest Reserve in Maran, Pahang, West Malaysia using mist-netting method. We captured a total of 1908 individuals representing 86 species and 29 families (i.e., 18.55% from two years postharvested forest, 25.10% from ten years post-harvested, 23.90% from twenty years post-harvested and 32.44% from thirty five years post-harvested forests). Forty nine species were caught in two years and ten years, 55 species in twenty years and 59 species in thirty five years' post-harvested forest. Seventeen species were common in all four types of forest. Pycnonotidae, Timaliidae and Nectariniidae were the most dominant families in all types of post-harvested hill dipterocarp tropical rainforest. Diversity analysis indicated that the bird species in twenty years post-harvested hill dipterocarp rainforest was most diverse (i.e., Fisher's Alpha Diversity Index; 16.34) and evenly distributed (i.e., McIntosh Evenness index E; 0.933) as compared to two years, ten years and thirty five years post-harvested forest. However, thirty five years post-harvested forest was richest in avian species (i.e., Margalef's Richness index R 1 ; 9.02) as compared to other post-harvested forest. The findings of this study revealed that logging and recovery process may affects on avian distribution and diversity. However, these effects may vary from species to species.

“…First, logging decreases the tree density [17][18][19][20] and basal area [9,17,18,21] of originally dominant species. Second, logging creates gaps with altered light conditions [17,22]. Third, logging increases the mortality of originally dominant species [17,18].…”

Ecological communities including tropical rainforest are rapidly changing under various disturbances caused by increasing human activities. Recently in Cambodia, illegal logging and clear-felling for agriculture have been increasing. Here, we study the effects of logging, mortality and recruitment of plot trees on phylogenetic community structure in 32 plots in Kampong Thom, Cambodia. Each plot was 0.25 ha; 28 plots were established in primary evergreen forests and four were established in secondary dry deciduous forests. Measurements were made in 1998, 2000, 2004 and 2010, and logging, recruitment and mortality of each tree were recorded. We estimated phylogeny using rbcL and matK gene sequences and quantified phylogenetic a and b diversity. Within communities, logging decreased phylogenetic diversity, and increased overall phylogenetic clustering and terminal phylogenetic evenness. Between communities, logging increased phylogenetic similarity between evergreen and deciduous plots. On the other hand, recruitment had opposite effects both within and between communities. The observed patterns can be explained by environmental homogenization under logging. Logging is biased to particular species and larger diameter at breast height, and forest patrol has been effective in decreasing logging.
