Changes in Plant Species Composition Within a Planted Forest in a Deciduous Agroecosystem in Ghana

Background

Early-successional tree plantations can promote regeneration of second-growth mixed-species forests. While non-native species have been studied for their role in enabling second-growth regeneration, this study surveys understories of plantations of trees native to Ghana in a post-maize site to explore the suitability of native trees for promoting second-growth regeneration.

L’abattage sélectif: une pratique agricole ancestrale au service de la régénération forestière (Selective clearing: Forest regeneration through an ancestral agricultural practice)

The author describes selective clearing of forests in crop fields. She notes the benefits of selective clearing such as increased speed of forest regeneration. Finally, the author contrasts the traditional agricultural practices of the Ntumu people to more destructive and widespread methods.

Identité et écologie des espèces forestières commerciales d'Afrique Centrale: le cas de Milicia spp. (Identity and ecology of Central African timber tree species: the case of Milicia spp.)

The authors explore the literature on two native tree species of commercial value in central Africa:Milicia excelsa and Milicia regia. Known locally as iroko, the authors note that exploitation of the trees have led to a decrease in its abundance. Finally, the authors argue that because the species are recognized as having economic importance, more research is needed on the species' ecologies in order to sustainably manage them.

Disturbance and Tropical Pioneer Species: Patterns of Association Across Life History Stages

BAckground

The authors studied pioneer species common in the Sinharaja World Heritage Reserve in Sri Lanka to characterize differences in relation to canopy openness and type, and intensity of disturbance using a combination of field work, canopy photos, and regression models.
