“…This study provides one of the first examples of how tropical biodiversity responds to logging roads per se (Laurance, 2004, Hosaka et al, 2014a), and also assesses what the broader impact of timber extraction is by accounting for the hidden additional effects of logging roads. These results show clear evidence that while vegetation structure and composition were significantly affected up to 34 m from the road edge, impacts on dung beetle communities penetrated much further and were discernible up to 170 m into the forest interior (Fig.…”

“…Tunnelling species, including larger species, were shown to associate with greater tree density and structure but with ground cover present. Micro-habitat and micro-climatic changes, have been highlighted as a key determinant in changes in small mammal and dung beetle populations, specifically a loss of canopy cover, following road creation (Malcolm and Ray, 2000, Hosaka et al, 2014b) but also in other extreme environments (oil palm plantations and logging yards) which represent similar extreme changes in habitat structure as with roads and logged forest edge (Edwards et al, 2014, Hosaka et al, 2014a). These findings highlight the unknown interactions between functional traits and community assembly, and the need for a greater understanding of assembly filters in varied disturbed habitats (Pollock et al, 2012, Van der Plas, 2012).…”

“…Understorey bird communities were observed to decline, while termite community composition differed with proximity to unpaved road clearings in Amazonia (Laurance, 2004, Dambros et al, 2013). Dung beetle communities were negatively affected by logging dumps, skid trails and access roads shortly after logging in Malaysia (Hosaka et al, 2014a), and small mammal community composition differed between logging road types (variations in size, use and time since adandonment) in Central Africa (Malcolm and Ray, 2000). However, most studies of the impacts of logging on biodiversity have either explicitly or implicitly avoided roads in their sampling protocols, leading to calls for further studies of their impacts on biodiversity and ecosystem functioning (Hamer et al, 2003, Broadbent et al, 2008; Laufer et al, 2013).…”

The demand for timber products is facilitating the degradation and opening up of large areas of intact habitats rich in biodiversity. Logging creates an extensive network of access roads within the forest, yet these are commonly ignored or excluded when assessing impacts of logging on forest biodiversity. Here we determine the impact of these roads on the overall condition of selectively logged forests in Borneo, Southeast Asia. Focusing on dung beetles along > 40 km logging roads we determine: (i) the magnitude and extent of edge effects alongside logging roads; (ii) whether vegetation characteristics can explain patterns in dung beetle communities, and; (iii) how the inclusion of road edge forest impacts dung beetle assemblages within the overall logged landscape. We found that while vegetation structure was significantly affected up to 34 m from the road edge, impacts on dung beetle communities penetrated much further and were discernible up to 170 m into the forest interior. We found larger species and particularly tunnelling species responded more than other functional groups which were also influenced by micro-habitat variation. We provide important new insights into the long-term ecological impacts of tropical logging. We also support calls for improved logging road design both during and after timber extraction to conserve more effectively biodiversity in production forests, for instance, by considering the minimum volume of timber, per unit length of logging road needed to justify road construction. In particular, we suggest that governments and certification bodies need to highlight more clearly the biodiversity and environmental impacts of logging roads.

“…Negative effects of roads have been shown on small mammals (Malcolm and Ray, 2000), birds (Develey and Stouffer, 2001;, elephants (Blake et al, 2008) and dung beetles (Hosaka et al, 2014). This has been associated with habitat changes and human activity, but increased noise levels can also have an impact (Laurance, 2015).…”

Les pistes forestières sont considérées comme des causes majeures de dégrada- tion des forêts en raison de leurs impacts directs et indirects sur le fonctionnement et la diversité des écosystèmes. Compte tenu de l’importance de l’exploitation forestière tropi- cale dans le monde, la bonne gestion de l’in- frastructure routière est cruciale pour réduire les impacts environnementaux associés à ces activités tout en réduisant les coûts des opé- rations. Notre étude visait à analyser comment la question des pistes de débardage avait été traitée dans la littérature scientifique. Des études publiées depuis 65 ans, la plupart en français, dans la revue Bois et Forêts des Tro- piques (BFT), ont été comparées à une série d’études plus récentes extraites des bases de données Scopus et Web of Knowledge. La moitié des articles BFT datent d’avant 1972, alors que les bases de données plus géné- ralistes indiquent une augmentation régu- lière, depuis cette date, du nombre d’articles publiés sur ce thème, qui atteint aujourd’hui un niveau record. Sur l’ensemble de la biblio- graphie, nous avons sélectionné, à des fins d’évaluation critique, 126 articles traitant des impacts et de la gestion des pistes forestières tropicales. Les articles de BFT se caractérisent par une attention particulière portée à des questions pratiques d’ingénierie, tandis que de nombreux articles rédigés en anglais se concentrent sur l’identification des impacts sur les écosystèmes forestiers. Les impacts environnementaux liés aux pistes forestières proviennent de la destruction du couvert pen- dant leur construction, de l’accroissement des effets de lisière, de l’érosion des sols, de la perturbation de la faune et de l’accès plus facile aux forêts pour la chasse et la colonisa- tion agricole. Nous présentons, sur la base de cette revue de la littérature, une liste de recommandations permettant de réduire ces impacts. En conclusion, nous constatons, que malgré l’intérêt continu pour le sujet des pistes forestières, nous savons très peu de choses sur leur devenir à long terme dans les paysages forestiers.

“…In tropical forest, major ecological disturbance caused by selective logging often resulted from construction of road networks, such as logging roads, skid trails, and log yards for extraction and transportation of timber. However, the effects of earthwork activities on forest-dependent species associated with ecological function have rarely been studied (Hosaka et al 2014). Furthermore, the concept of biological monitoring is still considered as new and has the potential to be developed and implemented in Malaysia.…”

Influence of deforestation on biodiversity of aquatic organisms was investigated in a stream in the Ulu Sedili Forest Reserve. The stream was monitored five (5) times from December 2011 until December 2012 with 2-month intervals. Sampling of benthic communities was carried out using rectangular dip net while water quality study using a YSI ProPlus meter and the rest were done in the laboratory. Physicochemical parameters and water quality index (WQI) calculation showed no significant difference among the investigated events. WQI classified the Berasau River between Class II (good) to III (moderate) of river water quality. In total, 603 individuals representing 25 taxa that were recorded with Decapods from genus Macrobrabchium were widely distributed. Several intolerant taxa, especially Ephemeroptera and Odonata, were also observed in this river. According to Pearson's correlation analysis, the richness and diversity indices were generally influenced by water quality parameters represented by WQI (P < 0.01). In conclusion, logging activities have strong attributes for variation in benthic macroinvertebrate assemblage.
