Natural Regeneration
Quantifying the Impacts of Defaunation on Natural Forest Regeneration in a Global Meta-AnalysisBackgroundIntact forests provide critical ecosystem services, such as carbon storage and climate regulation, which are heavily dependent on interactions between woody vegetation and animal species. However, defaunation is altering these interactions at a global scale. While previous studies have explored the effects of defaunation on individual ecosystems, a comprehensive global analysis quantifying its impact on natural forest regeneration has been lacking. This study conducts a meta-analysis to assess how vertebrate loss influences forest regeneration across multiple regions and ecosystems, identifying key taxonomic groups and ecological processes most affected by defaunation.

Erythrina (Leguminosae: Papilionoideae): A Versatile Genus for Agroforestry Systems in the Tropics.BackgroundThe genus Erythrina (Leguminosae) plays a crucial role in tropical agroforestry systems. These trees are adaptable and widely distributed in tropical and subtropical regions, with over 100 species globally. Erythrina species are known for their rapid growth, nitrogen-fixing capability, and adaptability to various environments, including low-fertility soils. Historically, they have been integrated into agricultural systems as shade trees, live fences, and forage sources. The diverse ecological benefits of Erythrina highlight its importance in addressing food security, environmental conservation, and rural livelihoods in tropical regions. Open access copy available |
The soil organic carbon in particle-size separates under different regrowth forest stands of north eastern Costa RicaBACKGROUND:Costa Rica, having experienced significant deforestation from 1950 to 1984, now sees a rise in secondary forests due to land abandonment and reforestation efforts. These forests vary widely in soil carbon accumulation, influenced by the previous land use intensity and the age of the forest. The paper investigates the role of secondary forests in Costa Rica in soil organic carbon (SOC) sequestration, a critical component in understanding climate change mitigation potential.

Evaluation of Forest Recovery over Time and Space Using Permanent Plots Monitored over 30 Years in a Jamaican Montane Rain ForestBACKGROUNDAn easily calculated recovery index would be of great value to studies of succession and restoration. The authors discuss the development of a new recovery index to assess the recovery of tropical forests after severe human disturbances. This index addresses current indices' limitations by incorporating the number and size of individuals within a community. The authors also propose a method for assessing recovery over time and space using permanent plots monitored over 30 years in the Jamaican montane forest. This provides more accurate estimates of forest conservation status. Open access copy available |
The potential of secondary forests to restore biodiversity of the lost forests in semi-deciduous West AfricaBACKGROUND:The human population in West Africa has increased considerably over the past four decades, leading to a high demand for food. This has led to the conversion of vast forest lands to agricultural lands in the region. Degraded forest landscapes have the capacity to regain fertility and naturally regenerate, resulting in the widespread spread of secondary forests in West Africa. Despite the significant presence of secondary forests in the region, there is rare knowledge about forest successional stages and general dynamics. Open access copy available |
Carbon sequestration and biodiversity following 18 years of active tropical forest restorationBACKGROUND:Vast tropical forests have been degraded and converted to other land uses such as agriculture. Degraded forests can regenerate naturally to improve biodiversity and carbon sequestration. However, major degradation factors, such as wildfires, hinder natural regeneration. Forest restoration can play an essential role in such circumstances. Nonetheless, research on methods to increase carbon storage and improve the ecosystem function of tropical forests is limited.

Co-benefits in biodiversity conservation and carbon stock during forest regeneration in a preserved tropical landscapeBackground:Recognizing the connection between carbon stock and biodiversity has become more crucial in light of the requirements set by international agreements. Consequently, a vital and indispensable measure for guiding relevant global environmental initiatives is to empirically investigating the potential advantages of restoring degraded areas through forest regeneration. This approach aims to boost both aboveground carbon stock and biodiversity, moving them closer to their natural levels. Available with subscription or purchase |
Do primary rainforest tree species recruit into passively and actively restored tropical rainforest?BackgroundIn many restoration projects, recruitment is dominated by a low diversity of regionally-abundant pioneer species and species with small, easily dispersed seeds. These species are characteristic of secondary rainforest and do not include the far more diverse suite of species characteristic of the original, primary rainforest. As restoring ecosystem processes is one of the central goals of restoration, this raises the question of which, if any, of the available rainforest restoration methods may be used to promote the recruitment of primary rainforest species.

An overview of forest loss and restoration in the Brazilian AmazonBackground:The accelerated process of forest loss and degradation in the Brazilian Amazon began in the 1970s due to government-promoted economic development initiatives. This led to significant deforestation, with approximately 20% (780,967 km2) of the region being affected . Nevertheless, the region still lacks scientific studies that reinforce the choice of best practices for forest restoration, and the information currently available is not enough to quantify what has already been recovered or the potential area to be restored.
