Secondary & Degraded Forest Restoration
Direct seeding to restore rainforest species: Microsite effects on the early establishment and growth of rainforest tree seedlings on degraded land in the wet tropics of AustraliaBackgroundIn Queensland, Australia, three degraded sites (a high elevation site, mid elevation site and low elevation site) that were dominated by non-native grass were studied. The study looked at how six different methods of sowing affected the establishment and growth of small and large seeds, as well as how it affected weeds growth and re-establishment. Before the sowing treatments were conducted, the weeds, since it often outcompetes seeds/seedlings, were removed using herbicides. The sowing treatments created microsites that either consisted of the seeds being buried beneath the soil or placed above the soil. Available with subscription or purchase |
Conserving Tropical Tree Diversity and Forest Structure: The Value of Small Rainforest Patches in Moderately-Managed LandscapesBackgroundDue to deforestation and degradation in rainforests, there has been an increase in small forest patches yet there is limited understanding of this structures contribution to biodiversity and ecosystem services. The authors of this study attempt to answer this question through studying a a moderately managed landscape in the tropics of Mexic Open access copy available |

Factors influencing community participation in mangroves restoration: A contingent valuation analysisBackgroundThis paper analyzes the willingness of a household to participate and pay for the benefits of a mangrove restoration program in the West Coast of India. In the second half of the twentieth century, this region has been threatened by shrimp cultivation, industrial development and hydroelectric projects, which overall made mangroves recede substantially.

Burning biodiversity: Fuelwood harvesting causes forest degradation in human-dominated tropical landscapesBackgroundIn the Northeastern Brazilian Atlantic Forest (BAF), extremely dense populations of poor, rural villages create chronic disturbances within the already heavily fragment Atlantic forest in favor of gathering hardwood fuel supplies. This hardwood is self-gathered without management techniques and burned inefficiently, and is driven by poverty, proximity to forest fragments, human labour availability, and lack of alternative energy sources. One of the most biodiverse, endemic, and endangered regions on the planet, this research seeks to study the impact of rural fuelwood development in the northeastern BAF. Open access copy available |
Creating space for large‐scale restoration in tropical agricultural landscapesBackgroundThe large-scale degradation and land-use conversion of ecosystems around the world has led to a global push to restore critical environments in order to preserve biodiversity and ecosystem services. One of the biggest challenges to these efforts though, is ensuring that preexisting land-uses are not simply displaced elsewhere. This article explores this problem, turning to the Brazilian Atlantic Forest as a case-study. The authors examine if restoration will lead to a discplacement of cattle production due to land-shortage. Available with subscription or purchase |

Ecological restoration success is higher for natural regeneration than for active restoration in tropical forestsbackgroundThis meta-analysis of 133 studies challenges the widely-held notion that active restoration methods are more effective at ecosystem restoration and hold higher conservation value than natural regeneration. Given the vast commitments for ecosystem restoration across the globe, and the high cost, effort, and resources needed for these commitments, this study proposes that increasing use of natural regeneration and assisted natural regeneration is necessary to achieve these commitments.

Accelerating tropical forest restoration through the selective removal of pioneer speciesbackgroundThis study presents initial findings on the impact of thinning on recovery of a selectively logged secondary forest in Sumatra. The study tests the hypothesis that thinning of pioneer species will produce stands with greater proportional basal area of late-successional species, effectively accelerating succession of the stand.
