The Diversity of Riparian Trees Vegetation at Around the Lawo River, South Sulawesi, Indonesia

Abstract

Abstrak. The study aimed to examine the diversity of riparian tree vegetation on the banks of the Lawo River in Soppeng Regency. This research is descriptive and carried out for three months, starting from June to August 2018. This study uses a quadrant method with a plot size of 20 m x 20 m. Data analysis was performed to calculate diversity index, evenness index, and similarity index of riparian tree vegetation. The results showed that riparian tree vegetation found in the littoral zone of the Lawo River totaled nineteen (19) species belonging to eight families. Plant Gmeliana arborea (fam: Verbenaceae) is the most common plant. Species Diversity Index is a medium category. The Species Evenness Index is high (close to 1). Riparian tree vegetation on the banks of the Lawo river observed at five points shows almost the same vegetation conditions.
