“…The richness of tree species was almost three times higher after 8 years of growth. The floristic change was characterized not only by an increase in the total number of species, but also by the proportion of tree species such as C. odorata, Entandrophragma angolensis, Trichilia monodelpha, and Trichilia prieuriana of Meliaceae family, and Antiaris toxicaria, Ficus exasperate, Milicia excelsa, and Morus mesozygia from the Moraceae family, known for their economic and ecological value Ofori et al 2007;Ouinsavi and Sokpon 2010). An increase in number of species with plantation age is a common observation (Abbasi and Vinithan 1999;Otsamo 2000a) as a result of management practices (Aude and Lawesson 1997;Hall et al 2003).…”

Plantations provide a micro-climate that can facilitate the regeneration of other forest species.Often exotic species have been tested for these kinds of functions. To determine the potential for indigenous trees as plantation species for their ability to foster forest species regeneration, this study was undertaken in a mixed indigenous plantation stand. Understories of the stand at 8 years of age were surveyed for plant diversity. The species richness increased by 24% per 1,000 m 2 between 2001 and 2008 and the number of families represented increased by 48%. The Shannon Diversity and Simpson Index values confirm a greater diversity 8 years after the plantation was established. The most abundant species in study plots were Chromolaena odorata and Cedrela odorata, which collectively represent about 54% of all species identified in the plots. The most species-rich families were Fabaceae and Euphorbiaceae representing 31% of the total species recorded. Asteraceae and Meliaceae were the two most dominant families, which collectively represent about 55% of all species identified in the plots. 47 forest tree species were found per 1,000 m 2 but those classified as 'saplings' occurred in low densities. The 47 tree species included pioneer species such as Entandrophragma angolensis, Milicia excelsa, and Ceiba pentandra. Growth rates of planted species were differed, with half of the tested species having similar growth capacity to the exotic species. Generally, planted indigenous species enhanced habitats for other forest tree species in degraded sites. The observed growth of indigenous species, if planted and protected, shows that they may help in biodiversity recovery within agricultural landscapes.

Fulani Knowledge of the Ecological Impacts of Khaya senegalensis (Meliaceae) Foliage Harvest in Benin and Its Implications for Sustainable Harvest. An improved understanding of how local people view their impacts on the resources they exploit and how they perceive that their resources are affected by other factors can provide insight into reasons some resources are overexploited and into strategies to conserve them. In West Africa, various tree species are heavily harvested by indigenous herders for foliage to feed their cattle. The reported declines in populations of several of these species have both biological and cultural implications, as cattle are an integral part of indigenous cultures and livelihoods. In this study we investigated Fulani herders' practices, knowledge, and perceptions of the ecological impacts of harvesting foliage of African mahogany, Khaya senegalensis, in Benin, and we tested some of the factors that may influence them. Fulani herders have detailed ecological knowledge of their impacts on the resources they depend on, and this is finely tuned to local ecological conditions. This knowledge is also widely spread across different sectors of Fulani communities and is highly congruent with scientific findings. However, due to the open-access context of K. senegalensis populations, detailed knowledge of sustainability does not translate into sustainable practices. Fulani perceptions of threats to populations differ significantly between ecological regions and provide key insights for locally relevant resource management plans. Traditional Fulani practices such as the sopoodu provide a basis for sustainable management of proposed Fulani-owned K. senegalensis plantations. This study illustrates how the assessment of local ecological knowledge, practices, and perceptions can play a key role in the design of culturally-appropriate conservation plans.

“…Plantios em Minas Gerais têm sido mais produtivos, atingindo valores de altura média de 3 m.ano -1 e DAP médio de 4 cm.ano -1 , próximo aos 5 anos de idade (Figura 1). Ofori et al (2007) afirmaram que o comércio contínuo da madeira nativa do mogno africano se encontra ameaçado pela intensa exploração das florestas e pelas dificuldades no estabelecimento de plantações de mogno em seu local de origem, devido ao ataque da broca de ponteira Hypsipyla robusta Moore, mesmo problema ocorre para a S. macrophylla em relação à H. grandella. O ataque da Hypsipyla destrói os brotos terminais, fazendo com que se bifurquem, retardando o crescimento e reduzindo o valor econômico da madeira (Grogan et al, 2002;Lim, 2007;Opuni-Frimpong et al, 2008a).…”

RESUMOO setor florestal brasileiro está em plena expansão e com um aumento gradativo de investidores florestais optando pelo cultivo de espécies de madeira nobre. O mogno africano (Khaya spp.) é uma espécie que vêm se destacando na preferência dos empresários como opção no investimento florestal. Porém, estudos e pesquisas sobre a espécie, principalmente no Brasil, são escassos. Assim, a presente revisão procurou reunir diversas fontes de publicação, nacionais e internacionais, abordando aspectos históricos do mogno, buscando aclarar as características da espécie e a experiência de outros países no manejo dessa cultura.Palavras-chave: mogno africano (Khaya spp.), plantios florestais, manejo florestal.African Mahogany (Khaya spp.) Cultivation and the Increase of the Activity in Brazil ABSTRACTThe Brazilian forest sector is fast growing with a gradual increase of forest investors choosing valuable hardwood species for tree crops. African mahogany (Khaya spp.) is a species that has been preferred by many entrepreneurs as a forestry investment. However, there are few studies and research on the species, especially in Brazil. Therefore, this review aimed to bring together diverse sources of national and international publications, discussing the history of the mahogany and characteristics of the species as well as the experience of other countries on the management of this crop.
