Abstract
The purpose of this study was to determine the diversity of lianas in the Bulla Forest, Umalulu District, East Sumba Regency. Sampling at the research site using a combined method (belt transect). The data obtained were analyzed using a quantitative descriptive approach with the Shanon Wiener diversity index formula. Plant samples were calculated using a quadratic transect with a plot size of 5 x 5 meters with a distance between them of15 meters placed perpendicular to the line towards a depth of 100 meters using a plot of 15 plots. Environmental factors measured were soil pH, humidity and air temperature. Measurements were made at each observation station. The results obtained 12 species consisting of Piper betle L., Dioscorea alata L., Paederia scandens L. Piper caducibracteum, Connarus semidecandrum jack, Smilax lasioneura, Cyclea barbata, Vitis quadrangula, Gynura procumbens (Lour.) merr., Melothria pendula L., Odontacarya truncata, and Cocculus carolinus L. The diversity index obtained was in the moderate category with a value of H' = 1.894.
期刊介绍：
The Journal Ecology (Bratislava) places the main emphasis on papers dealing with complex characteristics of ecosystems. Treated are not only general, theoretical and methodological but also particular practical problems of landscape preservation and planning. The ecological problems of the biosphere are divided into four topics: ecology of populations: study of plant and animal populations as basic components of ecosystems, ecosystem studies: structure, processes, dynamics and functioning of ecosystems and their mathematical modelling, landscape ecology: theoretical and methodical aspects, complex ecological investigation of territorial entities and ecological optimization of landscape utilization,
