| is.evaluation.notes | This study investigates if FSC certification associated with reduced-impact logging impact jaguar density in Peru and Guatemala using camera traps. In their analysis, the authors also considered the effect of time since logging using spatial replication, and co-factors such as distance to active logging road, distance to the nearest river and a vegetation index. | |
| is.evaluation.notes | Regarding the time since logging, the authors did not detect any effect. | |
| is.evaluation.notes | However, it is important to note that in the sampling design used, the treatments are not independent: all logging blocks are adjacent and relatively small. This is especially problematic since jaguars and other large herbivores have large home ranges which undoubtedly overlap with several, if not all, logging blocks. Any animal detection at a given location is dependant to the ecological conditions found at other logging blocks. Therefore, the sampling design does not allow to explore the effect of logging on animal populations by comparing the density of animals among logging blocks. The spatial design could however inform on animal movements and habitat use within the concession. Yet, the camera trap sampling was only conducted once (no temporal replicate). Therefore, the study does not allow to conclude on the impact of FSC. We can simply observe that certified logging concession can harbour relatively dense populations jaguars and large herbivores. Additionally, it must also be noted that the broader geographical context of the concessions (extensive tracts of forests) are favourable for jaguar population. | |

| is.evaluation.quotes | The authors found that:“jaguar density in Peru (4.54 ± 0.83 ind. 100km−2) was significantly higher than in Guatemala (1.52 ± 0.34 ind. 100km−2) but in both regions, densities were comparable to protected areas.” | |
| is.evaluation.quotes | Also, they used their sampling technic to evaluate the response of the medium and large-body mammal community. They found that:“logging had no negative impact on any of the species studied and actually had an initial positive impact on several herbivore species.” | |
| is.evaluation.quotes | The authors conclude that:“well-managed logging concessions can maintain important populations of large and medium-sized mammals including large herbivores and large carnivores as long as hunting is controlled and timber volumes extracted are low.” | |
