Impact of Revegetation of Rhizopora apiculata and Rhizopora stylosa on the Development of Mangrove Vegetation in Teluk Jor, East Lombok

Abstract

Mangrove degradation has become a source of awareness, especially the government, such as the Indonesian government. This study aims to assess the effect of planting Rhizopora apiculata and Rhizopora stylosa on the growth and development of mangrove species diversity that grows naturally in Teluk Jor, East Lombok. Methods of data collection using the method of observation and transects. Furthermore, the first data were analyzed using descriptive statistics, and the second was the importance of value index analysis and Shannon-Wiener (H ') analysis. In this study, five new species were found besides Rhizoproa apiculata and Rhizoproa stylosa. The new species are Avicennia marina, Ceriops tagal, Lumnitzera racemosa, Sonneratia alba, and Sonneratia casidaris. Furthermore, the highest index of importance was Sonneratia alba (tree 239.26, sapling 136.57, and seedling 66.89), and the lowest was Lumnitzera racemosa. Meanwhile, the diversity index is in the medium category, namely 1,451. In this case, the revegetation of two mangrove species in the study location significantly impacts mangrove vegetation growth and development. Therefore, the mangrove revegetation model in Teluk Jor can reference mangrove conservation in other areas.
