A study on lianes inventory in the permanent quadrats has been done in Kahuzi-Biega National Park, exactly in Tshivanga sector in South-Kivu, Democratic Republic of Congo. The objective of this work is to make inventory of all lianes in the quadrats as well as their relative density. The inventory was realized by four quadrats. Each quadrat dad 1 hector and is subdivided in to 16 square of 25 m x 25 m. In each quadrat, 4 squares have been selected at random. The number of undurduals was counted. We measured then the DBH of trees which lianes use as support. The researches have reached of the following results: the lianes are more represented (22 species) than the support trees (18species). This resultant is very different from that of Madidi (1999) who found a mono dominante forest of Babagulu. Less diversified in lianescent flora. We notice that the plants which have lianes are less numerous. The choice of the lianas to colonise a plant depends on the distance which separates the lianes of the host plant.
The present work which talks about the stydy of abundance of lianes in the quadrat of follow up after two years of implimantation in KBNP, goes from the high altitude precisely in Tshivanga secter has the objective of determining the lianes abundance as well as their similarity in our study sites. For alhiering our results, we have used the quadrat method. Each quadrat is of one hectare and it is subdivided in 16 squares of 25m x 25m for well determining the florastic composition of lianes we find there. After determining the florastic composition of lianes their inventories have Gallowed us to count 16 lianes species.In doing the analysis similarities of lianes and in considering the presence-absence datas, in using jaccard sign we find that in the squares a large number of lianes species live together in our study sites.The diversity analysis between quadrats show that the lianes are more diversity in the quadrat 3.
