Indigenous Trees in West African Forest Plantations: The Need for Domestication by Clonal Techniques

background

This study evaluates native species tree plantations across West Africa by summarizing existing information on the yield of those plantations, with particular focus on the Cameroon Forest Management and Regeneration Project. It considers the potential for vegetative propagation and clonal selection to increase growth rates and marketability of native species.

Impact of Exotic Plantations and Harvesting Methods on the Regeneration of Indigenous Tree Species in Kibale Forest, Uganda

background

In the late 1960s and early 1970s, exotic tree plantations were established in hilltop grassland sites of the Kibale Forest Reserve. In the late 1990s and early 2000s, many of these sites were selected for logging to encourage growth of native trees.

Research Goals & Methods

This study assesses the impact of both pitsawing and sawmilling of exotic species plantations on the colonization and regeneration of indigenous species. Tree enumeration was conducted within plots representing the different plantation types and harvesting methods in order to determine indigenous species richness and diversity.

Regeneration Pattern and Size-Class Distribution of Indigenous Woody Species in Exotic Plantation in Pugu Forest Reserve, Tanzania

background

This study examines the natural regeneration of indigenous tree species in an exotic tree plantation adjacent to a natural forest in a coastal forest of Tanzania.

Research Goals & Methods

Four dominant indigenous tree species were identified in the exotic plantation with diameter size classes between 10 to 35cm.

Native Tree Species Regeneration and Diversity in the Mountain Cloud Forests of East Africa

background

This study evaluates the diversity of native species regeneration within 3 native and exotic forest plantations of the indigenous forests of Tatia Hills, East Africa.

Research Goals & Methods

Researchers monitoried species diversity, richness and similarity of regenerated species between exotic plantations of pine, eucalyptus and cypress, as well as between native and exotic forests.

Regeneration of Indigenous Trees in Mgahinga Gorilla National Park, Uganda

background

This study examines the dominant exotic species, their distribution and effect on the regeneration of indigenous tree species in the formerly encroached area of Mgahinga Gorilla National Park, southwestern Uganda. The 4 habitat types examined were exotic woodlots, old croplands and natural forest habitat.

Research Goals & Methods

Indigenous species diversity was assessed by systematic sampling of the vegetation and soils in transect plots.

Caracterização do Dossel e do Estrato de Regeneração Natural no Sub-Bosque e em Clareiras de Uma Florestal Estacional Semidecidual no Município de Viçosa, MG

The authors analyzed clearings in a forest reserve belonging to the Federal University of Viçosa, MG, to compare the species and composition of clearing and forest understory vegetation. The found that the level of diversity (Shannon index) and species found (n= 69) were similar in the clearings and the understory in the surrounding forest. Coffee (Coffea arabica) and Picramnia regnellii were the most common species in both the clearings and the understory. The authors suggest that the dominance of coffee may be problematic for the regeneration of native species.
