The mangrove vegetation in the coastal environment has a vital role, especially as a regulation for CO2 and O2 gas exchange. Mangrove revegetation has significant relevance for local-scale climate change mitigation. This study aims to assess and describe the success of mangrove revegetation in mitigating climate change at a local scale. Ecological data research methods are through surveys, observations and transect methods. Furthermore, the collection of social data through surveys, interviews, questionnaires, and Focus Group Discussions (FGD). Meanwhile, the research data were analyzed using descriptive statistical analysis, and analysis of the mangrove vegetation structure through frequency, density, cover, and essential value index analyses. The study results found seven types of mangroves, namely Sonneratia alba, Rhizophora stylosa, Rhizophora apiculata, Avicennia marina, Bruguira gymnoryzha, Lumnitzara racemosa, and Ceriops tagal. Sonneratia alba and Rizoporastylosaare species with the highest importance value of 194.04 where S. alba found Poton Bako and R. Stylosa found in Tanjung Luar. As for social data and knowledge, people in areas with a distance of 0-50 meters from mangrove forest have a better understanding than people living in areas with an average percentage value perspective of 52 %. Then, most respondents agreed that mangroves could prevent abrasion and reduce heat temperatures, with the percentage of respondents responding more than 41 % and 61 %, respectively in all locations. Based on the essential value index and respondents’ perceptions, it can be concluded that the Sonneratia alba and Rizopora Stylosa are species that have the highest ecological function because they have good adaptability in the coastal areas of South Lombok making them suitable as species for revegetation programs in South Lombok, and for the next revegetation program should be involving people who are close to mangrove forests because they are the ones who know and feel the benefits of mangrove forests.

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.
