Forest Health and Global ChangeBackground:In addition to facing natural disruptions such as drought, windthrow, insect infestations, diseases, and fires, forests are increasingly grappling with intensified stressors of anthropogenic origin. These stressors arise directly through activities like logging and clearing or indirectly through climate change, air pollution, and invasive species. The pace of these human-induced disturbances surpasses the adaptability of evolutionary processes, thus shaping the future of global forests through intricate responses to multiple stressors spanning local to global scales.

Mapping carbon accumulation potential from global natural forest regrowthBackground:The authors note that previous studies have estimated the potential for carbon sequestration through afforestation and reforestation, but there has been less focus on the potential for natural forest regrowth. They also highlight the need for more accurate estimates of carbon accumulation rates in regrowing natural forests, as well as a better understanding of the factors that influence these rates.

Mapping tree species vulnerability to multiple threats as a guide to restoration and conservation of tropical dry forestsBackground:The global biodiversity crisis is exacerbated by anthropogenic threats such as climate change, habitat conversion, and overexploitation. Evaluating the susceptibility of ecosystems and species to these threats is imperative for strategic and cost-effective planning of restoration and conservation efforts.

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 |
Plant Respiration in a Warmer WorldBackground:It has been estimated that, globally, plants release 60 gigatons of CO2 during the respiration process. Many studies have shown that an increase in global temperature will increase leaves respiration rates, which in turn will decrease carbon uptake and increase atmospheric CO2 concentration (contributing even more to higher global temperature).

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.
