Tropical Wet Forest
Slowing Amazon Deforestation through Public Policy and Interventions in Beef and Soy Supply ChainsBackground:The process of deforestation, involving the extensive removal of mature forest, witnessed a notable decline, plummeting from a 10-year average of 19,500 km2 up to 2005 to 5843 in 2013—a remarkable 70% reduction. This reduction is believed to have initiated a chain reaction of positive consequences, including a diminished risk of regional rainfall inhibition, fewer alterations in river discharge and sedimentation, and an upswing in biodiversity conservation.

Exotic Eucalypts: From Demonized Trees to Allies of Tropical Forest Restoration?Background:Timber, being a product in high demand globally, presents a lucrative market opportunity, and restoration efforts could potentially generate income through the targeted extraction of this material. While the incorporation of commercially valuable exotic trees might incentivize farmers to participate in restoration projects, it raises significant ecological concerns among experts.

Survival and Early Growth of 51 Tropical Tree Species in Areas Degraded by Artisanal Gold Mining in the Peruvian AmazonBackground:Artisanal and small-scale gold mining has dramatically changed the landscape of tropical ecosystems, completely removing the soil and vegetation and polluting it with mercury disposals. In order to recover these degraded spaces, reforestation projects need to enhance their knowledge of restoration species growth and survival rates under different site conditions, as well as their fertilization needs. Goals:The authors of this study aim to (1) test 51 species with potential for ecological restoration and/or forest rehabilitation; (2) assess the potential for biochar amendments for use in reforestation efforts; and (3) explore species performance regarding their contrasting wood density traits.

Biochar Effects on Two Tropical Tree Species and Its Potential as a Tool for ReforestationBackground:Although biochar is starting to be recognized as a potential soil fertilizer, most of the current studies are focused on the growth response of herbaceous crops and not on the impacts of biochar on tree development. Goals:The authors measure the survival rate, growth, and biomass accumulation of the seedlings of two tropical tree species Terminalia amazonia (“terminalia”) and Guazuma crinita (“bolaina”) under abandoned gold mine conditions: nutrient-poor and sandy soil. The seedlings were tested under six different treatments (three doses of biochar, with and without fertilizer) for six months. Open access copy available |
Protocolo: Mantenimiento y Fertilización de Parcelas de ReforestaciónBackground:Como parte del trabajo de investigación que viene desarrollando el Centro de Innovación Científica Amazónica (CINCIA), se ha realizado la instalación de parcelas experimentales de reforestación en áreas degradadas por actividad minera en Madre de Dios. As part of the research work being carried out by the Center for Amazonian Scientific Innovation (CINCIA), experimental reforestation plots have been installed in areas degraded by mining activity in Madre de Dios.

Deforestation-Induced Climate Change Reduces Carbon Storage in Remaining Tropical ForestsBackground:Deforestation of tropical forests alters the biophysical properties of the forest's surface, which contributes to regional warming and drying. These environmental changes, in turn, could impact non-degraded forests, reducing the rates of photosynthesis and increasing the release of carbon through autotrophic respiration, as well as the risk of a wildfire. Consequently, it is important to improve the accuracy of carbon and climate benefits of a land management action (e.g., avoided deforestation) to enable a more effective valuation of the carbon credits issued for a specific project.

Lowland Tapirs Facilitate Seed Dispersal in Degraded Amazonian ForestsBackground:During their first decades of growth, secondary tropical forests have the potential to accumulate significative more carbon than old-growth stands. Nevertheless, recovering degraded forests' habitats could be an expensive task to achieve. In this context, natural regeneration processes, such as seed dispersal by herbivorous animals, offer a cost-effective tool to recover degraded forests, although this role remains largely unexplored.

Assessing the Carbon Capture Potential of a Reforestation ProjectBackground:Reforestation projects are receiving more and more attention due to their potential to sequester carbon and limit the increase of the global average temperature above 2 Celsius degrees. Consequently, is important to evaluate the accuracy of the GHG capture results made by the increasingly funded reforestation platforms. Open access copy available |
Patterns and controls on island-wide aboveground biomass accumulation in second-growth forests of Puerto RicoBackgroundSecondary or second-growth forests after land abandonment are a valuable contribution to global carbon sinks. Approximately 70% of the world’s tropical forests are secondary growth, so understanding the carbon sequestration rates on a large scale is important. Sequestration rates are controlled by both abiotic and biotic factors in each region. Open access copy available |
Aboveground carbon responses to experimental and natural hurricane impacts in a subtropical wet forest in Puerto RicoBackgroundCarbon sequestration is a major climate mitigating process. Tropical forests in particular sequester high amounts of carbon, however disturbance events such as storms can alter the ability of forests to sequester more carbon. Hurricanes create forest gaps and increase ground debris which both provide resources that may promote plant recruitment and growth. Open access copy available |
