Restoring degraded mine landscapes in Sub-Saharan Africa: Plant facilitatory mechanisms, strategies and knowledge gaps

Arthur A. Owiny, Paxie Wanangwa Chirwa, Jules Christian Zekeng, Theodore M. Mwamba et autres

Facilitation is an important process for restructuring plant communities in degraded areas. However, little is known about its role in enhancing tree recruitment in mine wastelands. We reviewed and synthesised studies investigating the facilitation process in recovering degraded landscapes and critically analysed …

The successional pathway of the tree community and how it shapes the fruit-feeding butterfly community in an Afrotropical forest

Anu Valtonen, Geoffrey Maxwell Malinga, Margaret Nyafwono, Philip Nyeko et autres

Abstract: The relative importance of different bottom-up-mediated effects in shaping insect communities in tropical secondary forests are poorly understood. Here, we explore the roles of vegetation structure, forest age, local topography (valley vs. hill top) and soil variables in predicting fruit-feeding butterfly …

Tree communities of different aged logged areas in an Afrotropical rainforest

Arthur A. Owiny, Anu Valtonen, Philip Nyeko, Geoffrey Maxwell Malinga et autres

Abstract Predicting the recovery processes in tree communities after logging is critical when developing conservation strategies. We assessed the patterns in tree communities in logged and primary forests in Kibale National Park, Uganda, representing 9‐ to 19‐year‐old clear‐cuts of former conifer plantations, …

Communities of trees along a tropical forest restoration gradient

Arthur A. Owiny

Increasing rates of deforestation in tropical forests have been linked to agriculturalists. A critical concern generating debate is how well communities of trees recover into a more species rich ecosystem after restoration planting. The aim of the study was to evaluate the …

Tree community reassembly after selective and clear-cut logging in an Afro-tropical rainforest

Arthur A. Owiny

Understanding the process of community reassembly is crucial for the conservation of biodiversity and rehabilitation of ecosystems. This study tested whether tree communities in logged forests follow an equilibrium (deterministic) or non-equilibrium (stochastic) model of succession. We assessed reassembly of tree communities …

Population structure and regeneration status of Prunus africana (Hook.f.) Kalkm. after selective and clear felling in Kibale National Park, Uganda

Arthur A. Owiny, Geoffrey Maxwell Malinga

Prunus africana is a globally threatened indigenous medicinal tree species, and food for many primates. Its population has declined in Sub-Saharan Africa due to unsustainable harvest and poor protection. In this study, we determined the population density, population structure and regeneration status …
