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.

National Potential and Priority Maps for Tree-Based Landscape Restoration in EthiopiabackgroundThis technical report was created by Ethiopia's Ministry of Environment, Forest, and Climate Change (MEFCC) and the World Resources Institute (WRI) as a first step in Ethiopia's large-scale forest restoration efforts aimed to improve livelihoods and address climate change.

Forest and landscape restoration severely constrained by a lack of attention to the quantity and quality of tree seed: Insights from a global surveybackgroundThis review article focuses on tree seed supply in the context of forest and landscape restoration (FLR). The article asserts that large-scale FLR commitments will require billions of tree seeds and seedlings, and that this supply is extremely inadequate in terms of not only quantity but also genetic diversity and quality. The article reviews 139 FLR projects worldwide and identifies widespread problems in the availability and diversity of tree seed supply. Open access copy available |
Natural regeneration as a tool for large‐scale forest restoration in the tropics: prospects and challengesbackgroundThis article is a review of natural regeneration in the context of large-scale forest restoration in the tropics. The article provides case studies of successful natural regeneration, pointing out the side benefits of genetic adaptation, traditionally-used species, and local biodiversity. These features also bring greater ecosystem resilience. Open access copy available |
Restoration of Degraded Tropical Forest LandscapesBackgroundDeforestation and the declining extent of tropical forests has negatively impacted ecosystem functions, services, and goods and has disproportionately harmed the rural poor of tropical countries. In the wake of deforestation, agricultural development and traditional methods of reforestation (plantations) have largely failed to provide sustainable livelihoods. This review article assesses the strengths and weaknesses of different tropical restoration methods to combat forest degredation and address rural poverty. Open access copy available |
The Potential for Species Conservation in Tropical Secondary ForestsBackgroundThe importance of tropical secondary forests for conserving biodiversity increases with the degradation of old-growth forests, yet little is known about the role that these forests play in promoting biodiversity. Geospatial and temporal factors influence the role of secondary forests in species conservation, and this synthesis of case studies evaluates the significance of these factors on regional and landscape scales.

Genetic Consequences of Tropical Second-Growth Forest RegenerationBackgroundThis article is an examination of the genetic impacts of old-growth deforestation among 24 year-old second-growth Iriartea deltoidea, a canopy palm, in a lowland Costa Rican forest. Iriartea is widely distributed throughout neotropical rainforests and displays a diverse range of size classes in mature forests. This species recolonizes second-growth forests with newly generated seeds, which are dispersed by birds and mammals. Open access copy available |
Satellite Data-Based Phenological Evaluation of the Nationwide Reforestation of South KoreaBackgroundSouth Korea's reforestation efforts since the 1950s have been evaluated for changes in biomass, area, and growing stock, but little has been done to study the phenology changes (seasonal changes) and photosynthetic activity, which will help in the preparation of new forest management in light of climate change.

Habitat Distribution of Dipterocarp Species in the Leyte Cordillera: An Indicator for Species – Site Suitability in Local Reforestation ProgramsBackgroundThis article presents the results of a vegetation study in primary forest areas of the Leyte Cordillera in the Philippines, sampling populations of 18 species of Dipterocarp across topographic habitats and elevation classes. As a young volcanic cordillera, this tropical region is dominated by rugged topography, with slopes as steep as 30 to 60 degrees. Open access copy available |
Carbon Sequestration Potential of Indian ForestsbackgroundWhile deforestation in the tropics is a common subject of concern, India has retained a net positive afforestation rate from 1951-2000, with greatest gains after 1980. These efforts have afforested 35 MHa. Open access copy available |
