Comparative Study of the Diametric and Spatial Structures of Guarea cedrata (A. Chev.) Pellegr. (Meliaceae) in the Semi-Caducified Forests of the Central Basin Forest Massif (Tshopo Province, DRC, Congo Basin)

The comparative study of the diametric and spatial structures Guarea cedrata (A. Chev.) Pellegr. was carried out in semi-caducified forests Tshopo forest massif Democratic Republic Congo. For this study, two reserves were selected: Yoko Forest Reserve Yangambi Biosphere Reserve, successively located Ubundu territory, 32 km southeast Kisangani Isangi 100 west same city. To conduct present devices 200 hectares each, installed, one other where all individuals with dhp ≥ 10 cm measured including their X, Y coordinates. A total 177 inventoried within 72 individuals, or 0.36 feet/ha Yoko, 105 0.525 Yangambi. basal area values are respectively 0.0695 m2/ha 0.1712 Both "stretched S" distribution is aggregative while random In general, perch positions stands independent from each other; however, there some dependence at small scale analysis
