Article
Full-text available
Data capturing multiple axes of tree size and shape, such as a tree's stem diameter, height and crown size, underpin a wide range of ecological research - from developing and testing theory on forest structure and dynamics, to estimating forest carbon stocks and their uncertainties, and integrating remote sensing imagery into forest monitoring prog...
Article
The Cuvette Centrale is the largest tropical peatland complex in the world, covering approximately 145,000 km2 across the Republic of Congo and the Democratic Republic of Congo. It stores ca. 30.6 Pg C, the equivalent of three years of global carbon dioxide emis- sions and is now the first trans-natio- nal Ramsar site. Despite its size and importan...
Article
There is increasing interest in altitude effects on structural attributes and aboveground biomass (AGB) in tropical forests. However, we continue to lack a clear understanding of relationships between structural attributes and AGB along altitudinal gradients in Central Africa. Using a new network of 76 permanent plots of 0.5 ha, the relationships b...
Article
African monodominant forests are frequently formed by Gilbertiodendron dewevrei (De Wild.) J. Leonard and commonly found close to mixed forests. However, previous studies have ignored differences between these two forest types in height-diameter allometry, which is extremely important for aboveground biomass (AGB) estimates. This study aims to eval...
Article
Full-text available
The responses of tropical forests to environmental change are critical uncertainties in predicting the future impacts of climate change. The positive phase of the 2015–2016 El Niño Southern Oscillation resulted in unprecedented heat and low precipitation in the tropics with substantial impacts on the global carbon cycle. The role of African tropica...
Article
Tropical forests are the most diverse and productive ecosystems on Earth. While better understanding of these forests is critical for our collective future, until quite recently efforts to measure and monitor them have been largely disconnected. Networking is essential to discover the answers to questions that transcend borders and the horizons of...
Article
Full-text available
Aim Tree crowns determine light interception, carbon and water exchange. Thus, understanding the factors causing tree crown allometry to vary at the tree and stand level matters greatly for the development of future vegetation modelling and for the calibration of remote sensing products. Nevertheless, we know little about large‐scale variation and...

The world's most extensive tropical peatlands occur in the Cuvette Centrale depression in the Congo Basin, which stores 30.6 petagrams of carbon (95% CI, 6.3-46.8). Improving our understanding of the genesis, development and functioning of these under-studied peatlands requires knowledge of their topography and, in particular, whether the peat surf...
Article
Full-text available
Structurally intact tropical forests sequestered about half of the global terrestrial carbon uptake over the 1990s and early 2000s, removing about 15 per cent of anthropogenic carbon dioxide emissions. Climate-driven vegetation models typically predict that this tropical forest ‘carbon sink’ will continue for decades. Here we assess trends in the c...
Article
Full-text available
The recent publication of the first spatially explicit map of peatlands in the Cuvette Centrale, central Congo Basin, reveals it to be the most extensive tropical peatland complex, at ca. 145,500 km². With an estimated 30.6 Pg of carbon stored in these peatlands, there are now questions about whether these carbon stocks are under threat and, if so,...
Article
The estimation and monitoring of the huge amount of carbon contained in tropical forests, and specifically in the above-ground biomass (AGB) of trees, is needed for the successful implementation of climate change mitigation strategies. Its accuracy depends on the availability of reliable allometric equations to convert forest inventory data into AG...
Article
Full-text available
Carbon is continuously being removed from the atmosphere by photosynthesis and stored in carbon pools (live, dead, and soil carbon) of forest ecosystems. However, carbon stock in dead wood and of trees with diameters at breast height (dbh) between 5 and 10 cm is often not considered in many studies carried out in the Congo Basin Forest. The relatio...
Article
Full-text available
The data of carbon stock of central African swamps forests are very few. This study carried out an assessment of the carbon stock of living biomass and coarse woody debris of three biotopes (flooded forest, seasonal flooded forest, and terra firm forest) of Likouala swamp forest (North of Congo). The average of the carbon stock are 190.72±98.7 tC/h...
Article
Peatlands are carbon-rich ecosystems that cover just three per cent of Earth's land surface, but store one-third of soil carbon. Peat soils are formed by the build-up of partially decomposed organic matter under waterlogged anoxic conditions. Most peat is found in cool climatic regions where unimpeded decomposition is slower, but deposits are also...
Article
Full-text available
Trees species diversity, richness, and similarity were studied in fifteen plots of the tropical rainforests in the northeast of the Republic of Congo, based on trees inventories conducted on fifteen 0.25 ha plots installed along different types of forests developed on terra firma, seasonally flooded, and on flooded terra. In all of the plots instal...

Full-text available
Au moment où la gestion durable des écosystèmes forestiers requiert une parfaite connaissance de la flore, celle du Congo en général et particulièrement celle des forêts marécageuses du nord-Congo, demeure encore peu connue. La présente étude vise à contribuer à une meilleure caractérisation de la diversité floristique des forêts marécageuses de la...

The study aimed to estimate the carbon stocks of above-and below-ground biomass in Lesio-louna forest (Republic of Congo). The methodology of allometric equations was used to measure the carbon stocks of Lesio-louna moist forest. The research was done with 22 circular plots, each 1,256 m 2. In the 22 plots, we made measurements on a total of 347 tr...

Full-text available
The paper contributes new data on fine root production in tropical forests from the Teke Plateau, an underexplored area of Africa that is dominated by grove forests. Importantly, this study contributes to our understanding of the role of the successional age of vegetation and the impacts of water availability on ecosystem functions, which may assis...
Article
Full-text available
s Tree aboveground biomass (AGB) distribution and carbon storage in different DBH (diameter at breast height) classes were calculated and compared between three different humid forest of the north of Congo (peat land's forest, seasonally flooded forest, and terra ferma forest) mainly in the forest of Likouala. AGB carbon stock varies in this study...

The research was aimed to estimate the carbon stocks of above-ground biomass (AGB) in Lesio-louna forest in Republic of Congo. The methodology of Allometric equations was used to measure the carbon stock of Lesio-louna tropical rainforest. The research was done with six circular plots each 40 m of diameter, with a distance of 100 m between each plo...

The study was aimed to estimate the carbon stocks of above- and below-ground biomass in Lesio-louna forest of Congo. The methodology of allometric equations was used to measure the carbon stocks of Lesio-louna natural forest. We are based pre- cisely on the model II which is also called non-destructive method or indirect method of measuring carbon...
