Abstract

The present research paper aims at characterizing and comparing understorey phytoecological diversity between the Martineau and Blanc-étoc methods in the abandoned former Guarrea cedrata (A. CHEV.) PELLEGR plantation, with a view to increase the adequate policy (strategies) in order to complete knowledge gaps of these ones. The experimental devices used are 50*50 m (Martineau method, 2023) and 50*50 m (Blanc-étoc, 2023).  All understorey species which reached a diameter greater or as equal as with 5,0 cm were numbered according to Letouzey (1982). In order to specify the phytoecological spectra (biological types, morphological types, diaspora types, temperament, leaves size and types). We used catalogue flora of vascular plants from Kisangani Districts and Tshopo Province in DR Congo. After analysis, it has been shown clearly that sarcochores, mesophylls, shade-tolerant species, simple trees and leaves are more or heavily observed and there is heterogeneity of understory species.  It is noticed that the Martineau method has got 38 species and 22 families. Whereas Blanc-étoc, 30 species and 15 families. This proves that there is common remark between the two methods for ecosystem.
