“…Previous studies using remote sensing and geographical information systems defined the type of land use and land cover in the study site (Zekeng et al ., 2019). As a result, it allowed us to choose to work only on the terra-firme forest while avoiding rivers and swampy vegetation types.…”

Tropical forests play an important role in biodiversity conservation and ecosystem functioning. Few studies have teased apart the independent effects of biotic and abiotic factors on aboveground carbon across tree size groups and the whole tree community level in a tropical semi-deciduous rainforest. This study aims to analyze the relative and independent effects of abiotic (topography, soil fertility/texture and disturbance) and biotic factors on carbon stocks across tree size groups, as well as at the whole tree community in semi-deciduous plots, including logged plots. We used data from 30 1-ha plots and 22,064 trees distributed in a semi-deciduous tropical rainforest of Cameroon. For each plot, we quantified disturbance, topography and eleven soil conditions. Besides, we quantified three taxonomic richness and diversity Gini index. We used structural equation models to test the hypothesis that all drivers have independent, positive effects on aboveground carbon stocks across tree-sized groups and the whole tree community. The logging disturbance decreased aboveground carbon stocks for the whole tree community and trees size groups across our site except for large trees. Topographical factors (i.e., slope and elevation) increased aboveground carbon (AGC) of the whole tree community and the large trees. In contrast, soil nitrogen (Nsoil) and clay proportion increased AGC of the small stems and understorey trees groups. This study found that biotics factors have some indirect and direct effects on AGC. Taxonomic diversity through niche complementarity had a positive relationship with aboveground carbon stocks across the trees size groups and the whole tree community, while diversity Gini index had strongest relationships with aboveground carbon stocks. The significant effects of structural diversity on aboveground carbon stocks of the whole tree community, large trees, and understory trees highlight the importance of maintaining a layered structure and tall trees in the forest.

Since the advent of the Coronavirus pandemic in 2019, medicinal forest plant species (MFPS) have played a primordial role as an adjuvant in the treatment/prevention of this pandemic. Today, the availability of MFPS could be adversely impacted in the future due to high demand. It was within this backdrop that this study assessed the current status of the main MFPS used by local people against COVID-19 symptoms in Deng-Deng forest community in Cameroon. The methodological approach involved the administration of questionnaires to 405 respondents including naturopaths, healers and heads of households; and botanical inventories of the main MFPS in transects of 2000mx20m (40ha). For 40% of the respondents, the demand for MFPS has increased since the advent of COVID-19; with 16% of the respondents affirming that the availability of MFPS has reduced. For 60%, the availability of MFPS would decrease in the near future. Total density of the 12 main MFPS was 30.14±2.86 stems/ha in 8 land forest cover types found. Understanding these medicinal adjuvant plant species variation is a crucial step in achieving their sustainable management.

“…Hence there is a need for a land use management plan. In fact, recent studies show that even classified forests are facing many anthropogenic pressures that lead to their degradation and deforestation (Zekeng et al, 2019;Djiongo et al, 2020;Fokeng et al, 2020;Temgoua et al, 2021). Therefore, the aim of this study is to present the changes in forest cover in the Mbalmayo forest reserve over the past 30 years, based on GIS analysis of satellite images.…”

This study was carried out in the forest reserve of Mbalmayo, Center Region of Cameroon, with the aim to analyze the dynamics of land use/land cover (LULC) changes over the past 30 years. The databases used were made up of 3 Landsat satellite images (5TM of 1990, 7ETM+ of 2005 and 8OLI of 2020). The satellite images were processed using ArcGIS and Erdas Imagine software. Ethnobotanical surveys were conducted to investigate the relationships between the local population and the forest reserve. The Mbalmayo forest reserve is consisted of seven main land cover namely: mature secondary forest, young secondary forest, savanna, fallows and crops, built, bare soil and water surface. The dynamics of the forest cover undergoes more significant changes between the years 1990-2005 with losses estimate at 4762 ha compared to the years 2005-2020 (2231 ha), with a marked decrease in the area of dense forests. This regression is much more important in dense forest vegetation. The forest cover lost 6993 ha (26.92%) of its surface, which corresponds to an average rate of deforestation of 233.1 ha/year. The survey revealed the need for NTFPs for the Mbalmayo reserve forest populations. Indeed, all respondents agreed that they use non-timber forest products from the forest, mainly for medication (37%), wood (34%) and food (24%). Therefore, it becomes urgent to redefine a management plan for the Mbalmayo forest reserve which will define how the forest must be managed in order to avoid the loss of large areas of forests disappearing each year under the human action, which exerts pressure on forest species, thus leading to their possible disappearance.
