Occurrence of Nodulation in Unexplored Leguminous Trees Native to the West African Tropical Rainforest and Inoculation Response of Native Species useful in Reforestation

Background

Few studies examine the ability of leguminous tree species to nodulate and fix atmospheric N, especially symbiotically with rhizobia; this study seeks to fill that research gap.  The occurrence of nodulation was determined in 156 mature leguminous species growing in 6 natural forest areas in south-eastern Guinea and an in situ experiment of rhizobia inoculation was performed on 8 selected tree species.

Agro-Successional Restoration as a Strategy to Facilitate Tropical Forest Recovery

background

Tropical forest restoration to address resource degradation and climate change is a growing trend in tropical regions. However, a lack of funding and provision for human livelihoods often hinders forest restoration projects. Traditional agroforestry systems are often seen as a way to connect farmers to forest restoration, and the article outlines existing agroforestry models.

Floristic Composition, Structure and Natural Regeneration in a Moist Semi-Deciduous Forest following Anthropogenic Disturbances and Plant Invasion

background

This study examines the floristic composition, structure and natural regeneration in three forest types: disturbed forest (DF), undisturbed forest (UF), and disturbed-invaded forest (DIF) in Tinte Bepo forest reserve in Ghana. In addition, this study also considers how anthropogenic disturbances and plant invasion affect plant species composition.

Uses, Management and Economic Potential of Garcinia kola and Ricinodendron heudelotii in the humid lowlands of Cameroon

Background

This article describes two common fruit and medicinal trees (non-timber) that grow in secondary forests in the lowlands of Cameroon. The trees are found to have a mixed effect in an agroforestry environment; sometimes they improve crop production, sometimes they do not. Fruit are consumed by families and sold in markets.
