The study was aimed to feature the forest ecosystem of the reserve from the stand point of is floristic composition, to examine the diversity and to carry out the measurement of the “DBH“ of trees. The survey carried on a sample hectare has led to the following records:
The most represented families in terms of number of species are: Fabaceae 23,5%, Myristicaceae 11,5%, Euphorbiaceae 10,5%, Sterculiaceae 8,3%, Meliaceae 6,4%. The total ground surface is 39,13m²/hectare, 409 stems of trees of DBH ≥ 10 cm censused as belonging to 108 different species regrouped into 38 botanical families. The highest relative diversity has been observed among the families of fabaceae (14,8% of species) and meliaceae (9,3% of species).
This research has been dedicated to the study of possibilities to develop a buffer zone around the National Parc of Kahuzi – Bièga (Pnkb) at Bugorhe and Irambi – Katana, South – Kivu, DR Congo. The study has examined the possibilities to allocate bordering fallow and under-exploited land into the buffer zone, for farming and tree planting by the little neighboring farmers. It has shown that seven lots bordering the park with 920Ha total area provide rentable farms to 473 neighboring farms. Nearly 494Ha of these lots are either fallow or under-exploited, which is about 53,7%, and are likely to be transformed into a buffer zone upon negotiating with land owners for buyout.
