- Abstract:
- ... This paper presents ideas and strategies to prevent illegal logging of timber. Globally, illegal logging is a substantial problem. While the exact amount of timber harvested illegally is unknown, the problem is estimated to cost USD$30–100 billion annually. Criminological theories suggest intervention mechanisms that could either prevent or severely limit illegal logging in the forests. Utilizing ...

- Abstract:
- ... Production forests are a dominant feature of most tropical forest landscapes and it is therefore important to understand the effects of timber extraction on the resident fauna. Here we investigate the effects of reduced-impact logging (RIL) on medium- to large-sized terrestrial mammals in two Jamari National Forest logging concessions, south-western Brazilian Amazonia. We used camera traps ...

- Abstract:
- ... Unsustainable timber management, primarily via Conventional selective Logging (CL), has resulted in severe habitat degradation and biodiversity loss. Sustainable techniques, principally Reduced Impact Logging (RIL), are therefore essential for conserving highly threatened, physiologically sensitive taxa such as amphibians. In this study we compare the effects of CL and RIL on stream amphibians ...

- Abstract:
- ... Cable logging is a common harvesting technique for steep slope conditions, despite the safety hazard for the operators, which is mainly related to failure of cables or anchor trees. The multiple factors that determine whether a tree should be considered as an anchor make it difficult to estimate the actual suitability of the anchor tree from a safety perspective during logging. To address ...

- Abstract:
- ... After natural forest disturbances such as wildfires, windstorms and insect outbreaks, salvage logging is commonly applied to reduce economic losses and mitigate subsequent disturbance risk. However, this practice is controversial due to its potential ecological impacts, and its capacity to mitigate or increase the risk of subsequent disturbances remains unclear. Salvage logging removes and alters ...

- Abstract:

Some of these methods can be applied to monitor pumping tests to identify fractures contributing to groundwater flow and, with this, determine hydraulic conductivity and transmissivity along the well. We present a procedure to identify ...

Noise dosimeters were used to measure exposures of 31 loggers at two cable operations and five mechanized operations in the United States. Activity cards were employed to evaluate hearing protector usage. Ninety-two percent of cable operation loggers were overexposed to noise ...

- Abstract:
- ... Selective logging is very widespread across the tropics and can alter the habitat for myriad wildlife species. But while many studies have assessed the impacts of past logging on forest animals, far fewer have investigated how species respond to logging while the timber operations are actually going on. This is an important knowledge gap because, considering the prevalence of logging across ...

Habitat degradation due to forest harvesting contributes to biodiversity loss; therefore, it is necessary to implement logging management aimed at reducing its impact. Forest management by reduce-impact logging (RIL) involves cutting trees following regulations focused on diminishing the impact on biodiversity ...

- Abstract:
- ... Over half of the world's tropical forests are used for timber extraction by selective logging. Even though these forests are degraded to a variable degree, they are still important for tropical forest biodiversity. It is not yet known how biodiversity is impacted during and immediately after logging, and how fast it recovers. Here, we use ecoacoustics, and specifically the recording and analysis ...

Anthropogenic disturbance of tropical ecosystems can re-configure mammalian communities, frequently through a process of differential impact on animal species, whereby medium- and large-bodied animals are more impacted than small-bodied animals, which often are even favored. Here we examine if logging –a prevalent activity in the tropics– drives a pattern of differential defaunation ...
