Formerly, the Nzundu forest massif covered almost the two third of Kwenge and Imbongo, and a part of Kipuka districts. Nowadays, it is represented by a reduced forest fragment with a surface of about 50 to 70 hectares. The flora inventory was performed on the forest trees at dbh ≥ 10 cm, measured at 1.30 m of high at the breast height trunk, allowed to identify 134 different kinds of plants divided into 109 genera and 31 families. Fabaceae, Malvaceae, Rubiaceae, Euphorbiaceae, Moraceae, Meliaceae and Sapotaceae are the most represented families. The value of the basal area got in this forest massif is high or 49.89 m 2 .ha -1 . As to the ecological spectra and phytogeographical distribution, mesophanerophytes, sarcochores, mesophyles and the Congolian-Guinea element are the most numerous. The density of the forest trees listed in this forest massif is of 422 trunks.ha -1 . Brachystegia laurentii is the species having the highest number of feet or 11.8%. The values of Shannon and of Equitability indices calculated are of 4.7 and 0.9 respectively.

Phytoecological study of Nzundu massif forest of Imbongo city, Kwilu Province, Democratic Republic of the Congo

A floristic and structural composition studies of Kponyo forest, a forest close to the hunting field of Bili Uele, was carried out with the aim of knowing the variability of the forest types through the evaluation of the parameters such as abundance, taxa predominance, basal area, biodiversity indices and the mode of space distribution of the dominant species in each inspected site. The method of subplot made it possible to sample two hectares (8 pieces of 50 m X 50 m). On the whole, 636 individuals belonging to 173 species and 66 families were inventoried. The species Gilbertiodendron dewevrei abounds the hydromorph land forest while the species Garcinia epunctata abounds the firm land forest. The Fabaceae family dominates this florule. Basal area average is 28,14m2/ha. The analysis according to the K repley® function of Gilbertiodendron dewevrei and Garcinia epunctata shows a random distribution within the settlement.

Floristic and structural studies of two mixed vegetation communities on hydromorph and firm land forests of Kponyo (Bas-Uélé province, Congo DR)

An ecological study based on the natural regeneration of the undergrowth was carried out in the S. Lisowski botanical garden of the Faculty of Science, Kisangani University. A floristic inventory was conducted taking into account the height and diameter of all individuals. From this inventory, 3901 individuals have been recorded and grouped into 6 species, 6 genera, and 5 families; for the species assessed according to the scale of abundance - dominance of BRAUN BLANQUET, 8 species grouped into 8 genre and 7 families were counted. The obtained result show the dominance of the Leptonychia tokana (1232 feet or 31.58%) species, followed by Costus lucanusianus (881 individuals or 22.58%) and finally Tricalysia bequaertii (741 feet or 18, 29%). Among the Spectra evaluated according to the scale of abundance-dominance of BRAUN BLANQUET, Trachyphrynium braunianum and Anthurium ferrierense are the most abundant. The most represented families in the undergrowth of the garden are the Rubiaceae, Marantaceae, Malvaceae and Costaceae.
