Abstract


The present study is based on the structural analysis of the diameters of the three species: Musanga cecropioides R.BR, (Parasolier), Prioria balsamifera (Vermoesen) Breteler (Tola) and Prioria oxyphylla (Harms) Breteler (Tchitola) Illegal settlements by people living on the Yoko Forest Reserve. P. balsamifera and P. oxyphylla do not have a good regeneration, M. secropioides to a trend towards a good generation but does not have individuals from class 9. The results show that M. cecropioides is declared non-vulnerable (94.5%) in Yoko while P. balsamifera and P. oxyphylla are said to be vulnerable. This is explained by the low vulnerability index obtained for these two species, ie 30.9% and 26.7%.

Author Keywords: Forest, exploitation with reduced impact, plant species, minimum diameter, diametric structure, Democratic Republic of Congo.


Abstract: (french)


Cette étude se base sur l’analyse structurale des diamètres des trois essences : Musanga cecropioides R.BR, (Parasolier), Prioria balsamifera (Vermoesen) Breteler (Tola) et Prioria oxyphylla (Harms) Breteler (Tchitola) et leur vulnérabilité face à leur exploitations illicites par les populations riveraines de la réserve forestière de Yoko. P. balsamifera et P. oxyphylla n’ont pas une bonne régénération, M. secropioides à une tendance allant vers une bonne génération mais n’a pas d’individus à partir de classe 9. Le résultat obtenu montre que l’essence M. cecropioides est déclarée non vulnérable (94,5%) à Yoko alors que P. balsamifera et P. oxyphylla sont dites vulnérables. Ceci s’explique par le faible indice de vulnérabilité obtenu pour ces deux dernières essences, soit 30,9% et 26,7%.

Author Keywords: Forêt, exploitation à impact réduit, essence, diamètre minimum, structure diamétrique, République Démocratique du Congo.
