Evaluating the success of direct seeding for tropical forest restoration over ten yearsBackgroundThe main causes of deforestation in the Amazon are large-scale agriculture and cattle ranching, which have led to the loss of millions of hectares of forest. To address this issue, different mechanisms have been implemented since 2005 to reduce deforestation and increase forest restoration. However, highly modified, degraded areas with a long history of use may take a long time to regenerate naturally or may not recover into a secondary forest. Therefore, active restoration methods are needed to accomplish this massive obligation. Available with subscription or purchase |
Tree Communities in Three-Year-Old Post-Mining Sites Under Different Forest Restoration Techniques in the Brazilian AmazonBackground:Mining has been identified as a major contributor to forest loss, leading to the need for effective restoration techniques in post-mining sites. In this context, the knowledge of floristic composition is crucial for managing natural regeneration, selecting species for restoration plantings, and aiding conservation programs of threatened plant species. One well-known example of mining impacts on the Amazon rainforest vegetation is located in the Paragominas municipality, Pará, Brazil. Open access copy available |
Mining in the Amazon: Importance, impacts, and challenges to restore degraded ecosystems. Are we on the right way?Background:With mining playing a significant role in the economies of Amazonian countries, there is a growing urgency to understand, mitigate, and restore the degraded ecosystems that result from these mining operations. These tasks present a complex set of challenges, including technological limitations, legal inconsistencies, and a shortage of qualified professionals. Available with subscription or purchase |
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.

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.

Higher Fire Frequency Impaired Woody Species Regeneration in a South-Eastern Amazonian ForestBackground:The more and more common forest fires in the Amazon rainforest, caused after fire escape from pasture or deforested lands, cause unpredictable changes to the forest structure. Therefore, it is essential to assess the resilience of these ecosystems after being impacted by fire events and the likelihood of maintaining forest tree species and not being replaced by savanna species.

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.

Ten principles for restoring campo rupestre, a threatened tropical, megadiverse, nutrient-impoverished montane grasslandBackgroundIn the U.N. Decade on Ecosystem Restoration, one of the most overlooked ecosystem types is tropical grasslands. Studies on these ecosystems are lacking, as are the foundations for restoration. These foundational points of policy, practice, and governance in addition to science need to be addressed. The authors provide 10 principles to restore the campo rupestre, a tropical grassland that is threatened by human activities including mining. Available with subscription or purchase |
Identifying hotspots for ecosystem restoration across heterogeneous tropical savannah-dominated regionsBackgroundIn the U.N. Decade on Ecosystem Restoration, ecological restoration projects are a valuable tool for meeting global sustainability climate goals. Tropical regions are at the center of attention for their high biodiversity, carbon sink, and benefits to culture and human livelihood. Tropical dry savannahs are understudied even though they cover a large portion of tropical regions. Savannah dominated landscapes are valuable for their high plant diversity and vegetation type variation and high species turnover. Benefits to restoring these ecosystem types are also understudied.
