Mangroves are threatened with extinction worldwide. Many mangrove reforestation projects have been developed, but very few have achieved their restoration objectives. With the ambitions to contribute for rehabilitation of man�grove ecosystems, the aim of this study was to assess the effects of substrate composition and level of insertion on the g...

In recent decades, there has been a significant reduction in mangrove vegetation cover. Anthropogenic activities are increasingly affecting this ecosystem, even in protected areas. This study aimed to assess the impact of logging on the floristic composition and structure of mangrove vegetation in the Sanaga river estuary. The study was conducted i...

Ecological restoration is considered like the practical and sustainable management option for degraded mangroves. The ecological status of reforested mangrove areas (RMAs) in Douala-Edea National Park (DENP) is not well understood, despite extensive restoration projects. This study aims to estimate standing biomass and litterfall production in thre...

Mangroves are essential ecosystems for the environment and are home to a particular biological diversity. They face many constraints, in particular, that of the invasion of exotic species such as Nypa fruticans. The research aim consisted of the characterization of Nipa palm traits in the Wouri estuary. The study was carried out in five points loca...

Cameroon mangroves are protected over 20 years by both Management of Forest and Fauna and Environmental Management Legal Framework laws. However, these juridical tools are not efficient in the field regarding the rate of mangrove forest depletion around coastal cities in the country. This work aims to identify the main factors of mangrove degradati...

Mangroves play relevant roles in coastal communities. Despite their high values, they suffered from human pressures which have caused biodiversity reduction and death of species unable to adapt to change. This survey aims to evaluate the diversity of mangrove molluscs, determine their distribution within stands and identify potential biological ind...

Mangroves supply essential ecosystem services to tropical informal economies. In the Cameroon coastal region, the impacts of various projections on change in temperatures and precipitations sound low compared to the pressure of human activities. This survey evaluated the sensitivity of local population on the impact of climate change and the vulner...

Mangroves forests are sheltering a diverse and distinctive macrofaunal assemblage mainly made of brachyuran crabs. These invertebrates operate relevant ecological roles in terms of structure and function in mangrove ecosystems. This study aims to improve investigations on mangrove crabs in Cameroon. Study areas were selected between Limbe and Kribi...

The macrobenthos of mangroves is dominated by crabs and molluscs, which have a significant ecological role in terms of the structure and function of mangroves. The aim of this study was to determine the abundance and biological diversity of these groups in the Wouri River estuary mangrove in Douala, Cameroon. Three methods of crabs capture (excavat...
