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...

Les forêts tropicales humides du bassin du Congo sont encore mal connues dans leur fonctionnement bien que leurs rôles dans l'atténuation du climat aient été rapportés depuis quelques décennies. Dans le but d'améliorer la connaissance du fonctionnement des forêts tropicales pluvieuses dans le bassin du Congo, une étude sur la décomposition des gros...

In order to improve the knowledge of the functioning of tropical rainfall forests in the Congo basin ,a study on the quantification of the stocks of carbon in coarse woody debris was done in Likouala’s area, in Republic of Congo. To achieve this goal,14 squares plots of 50mx50m had installed on the whole study area, including ten plots in primary f...

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...

The Boubissi forest exploitation unit is one of the forest management units assigned to logging. Knowledge of the existing floristic resource through a management inventory is a preliminary operation allowing the planning of the logging activity. In the Boubissi forest exploitation unit, floristic diversity was studied from the floristic surveys ma...

... They occupy at least 440,000 km 2 , and perhaps more than 600,000 km 2 if extensive wetlands in South America are confirmed to be peat-forming 2,4 , and have a C store that is equivalent to 30% of the C held in rainforest vegetation 12 . Tropical peatlands have their greatest extent in Southeast Asia 2,13-18 , Africa 1,2,[19][20][21][22][23][24] , and Central and South America 2,4,[25][26][27][28][29] (Table 2). Southeast Asian peatlands were described in scientific accounts from the early twentieth century 30 , but peatlands across the rest of the tropics have largely only been documented since 2010. ...
... Le stade de décomposition des arbres morts a été apprécié visuellement en fonction du degré de pourritures que présente l'arbre. Ainsi 4 différentes classes ont été retenues : les arbres morts récemment sont dans la classe I, les arbres morts avec 25 % de pourriture sont dans la classe II, ceux avec 25 à 50 % de pourriture sont dans la classe III puis dans la classe IV les arbres morts avec plus de 50 % de pourriture (Ifo et al., 2018). Aussi, la diversité animale vivant dans les arbres a été appréciée. ...
... The estimated CWD carbon stocks obtained in our field were about double compared to others studies done in Congo Basin Forests. Ifo et al. (2017) analyzed data in the Likouala forest (Republic of Congo) and found an average of 9.45 t C/ha. In the northern Republic of the Congo, Ekoungoulou et al. (2018) reported that the mean of CWD stocks varied between 8.9 Mg/ha and 19.96 Mg/ha in Ipendja forest management unit. ...
... In the Southern Cape forests, the ratio values of 3.1 for woody and 4.5 for herbaceous plants were relatively higher when compared to respectively 1.4 and 2.6 for this study. The ratio values in the tropical moist forests in the Congo Basin of 4.2 (160 species and 38 families) for tree species in the Congo-Brazzaville area (Koubouana et al. 2015) and of 5.7 (195 species and 34 families) for liana species in the Democratic Republic of Congo (Ewango et al. 2015) were much higher than for the reported studies in Afromontane forests, and particularly this study. ...
... Understanding of species richness, ecological and structural traits are indelible for conserving the forest diversity [9]. There are various indices for assessing the diversity and richness of species namely Shannon-Wiener index, Margalef index, Simpson index, etc. Shannon diversity index was mainly used for identifying richness and diversity of trees species [10]. In 1958 Margalef has markedly popularized concept of species diversity among the scientific community [11,12]. ...
