Forest structure recovery around West Africa’s last great rainforest: Modelling complex dynamics in Taï national park
Recovery rates depend on attribute: diameter > height > biomass. • Biomass recovery is slowest, needing over 100 years. • Cocoa fields show the fastest recovery across all structural attributes. • Gold mining sites show very slow recovery due to severe soil degradation. • Remnant trees are key to rapid recovery. Tropical secondary forests play a key role in restoring biodiversity and biomass, yet their recovery dynamics remain poorly understood i…
What motivates West African cocoa farmers to value trees? Taking the 4 W approach to the heart of the field
West Africa, the largest cocoa‐producing region globally, has experienced significant deforestation in recent decades, leading countries to implement large‐scale agroforestry policies; however, most studies on farmers' adoption of agroforestry fail to consider the social (Who?), historical (When?), geographical (Where?), and ecological (What?) factors that influence their motivations to value trees. Drawing from a sample of 150 farmers responsibl…

Fragmentation is the main driver of residual forest aboveground biomass in West African low forest-high deforestation landscapes
Tropical forests play a crucial role in climate regulation due to their high carbon sequestration capacity. However, degradation and disturbances in these forests may result in significant carbon losses. This study focuses on the impact of various biophysical, anthropogenic, and landscape factors on aboveground biomass (AGB) in heavily disturbed landscapes of Côte d'Ivoire (West Africa), a typical low-forest and high-deforestation country. AGB es…
The great mistake of plantation programs in cocoa agroforests – Let's bet on natural regeneration to sustainably provide timber wood
Cocoa production has been one of the main drivers of forest loss in West Africa. In the resulting post-forest landscapes, agroforestry has often been recognised as a solution to reconcile the preservation of trees and agriculture. Thus, a large number of tree plantation programs have been carried out in cocoa fields. Despite these major investments, the success of these plantations as a tool for "reforestation" of landscapes and sustainable timbe…
Lessons from a regional analysis of forest recovery trajectories in West Africa
In West Africa, very poorly documented are the recovery trajectories of secondary forests, and even less is known about the origin of the observed variability in recovery rates. To understand the relative importance of local and regional environmental conditions on these trajectories, we inventoried all trees larger than 2.5 cm DBH on 236 plots (0.2 ha), aged from 0 to 45 years plus controls, on eight chronosequences representing the typical regi…
How wildfires increase sensitivity of Amazon forests to droughts
The phenology of tropical forests is tightly related to climate conditions. In the Amazon, the seasonal greening of forests is conditioned by solar radiation and rainfall. Yet, increasing anthropogenic pressures (e.g. logging and wildfires), raise concerns about the impacts of forest degradation on the functioning of forest ecosystems, especially in a climate change context. In this study, we relied on remote sensing data to assess the contributi…
Aboveground forest biomass varies across continents, ecological zones and successional stages: Refined IPCC default values for tropical and subtropical forests
For monitoring and reporting forest carbon stocks and fluxes, many countries in the tropics and subtropics rely on default values of forest aboveground biomass (AGB) from the Intergovernmental Panel on Climate Change (IPCC) guidelines for National Greenhouse Gas (GHG) Inventories. Default IPCC forest AGB values originated from 2006, and are relatively crude estimates of average values per continent and ecological zone. The 2006 default values wer…

Recent deforestation drove the spike in Amazonian fires
Tropical forests are of global importance even though they only cover around 10% of the Earth's land surface. They store large amounts of carbon and host between one-half and two-thirds of the world's species (Lewis 2006). Small changes in the tropical moist forest—the most biodiverse biome within the tropical forests—may lead to global impacts on climate dynamics and warming, water cycles, and the loss of biodiversity. If the current rates of de…
Can timber provision from Amazonian production forests be sustainable
Around 30 Mm 3 of sawlogs are extracted annually by selective logging of natural production forests in Amazonia, Earth’s most extensive tropical forest. Decisions concerning the management of these production forests will be of major importance for Amazonian forests’ fate. To date, no regional assessment of selective logging sustainability supports decision-making. Based on data from 3500 ha of forest inventory plots, our modelling results show t…
Optimal strategies for ecosystem services provision in Amazonian production forests
Although tropical forests harbour most of the terrestrial carbon and biological diversity on Earth they continue to be deforested or degraded at high rates. In Amazonia, the largest tropical forest on Earth, a sixth of the remaining natural forests is formally dedicated to timber extraction through selective logging. Reconciling timber extraction with the provision of other ecosystem services (ES) remains a major challenge for forest managers and…
Climate change would lead to a sharp acceleration of Central African forests dynamics by the end of the century
Impacts of climate change on the future dynamics of Central African forests are still largely unknown, despite the acuteness of the expected climate changes and the extent of these forests. The high diversity of species and the potentially equivalent diversity of responses to climate modifications are major difficulties encountered when using predictive models to evaluate these impacts. In this study, we applied a mixture of inhomogeneous matrix …
