Mangrove Vegetation Zoning Density and Pattern in Wonosari Village, Panai Hilir District, Labuhanbatu Regency

Introduction

Indonesia is renowned for being home to the largest mangrove forest in the world, covering an impressive area of 3.2 million hectares, which accounts for approximately 22.6% of all existing mangrove forests globally. The country's mangrove forests play a vital role in maintaining the health of the environment, serving as a natural barrier against coastal erosion, providing a habitat for various fish species and other fauna, and acting as a significant carbon sink in efforts to mitigate climate change. In 2021, the national mangrove map was updated, revealing that the area of mangrove forests had reached 3,364,080 hectares. This study aims to investigate the distribution of mangrove vegetation density and form a pattern of mangrove zoning in Wonosari Village, Panai Hilir District, Labuhanbatu Regency, over the period of 2002 to 2022.

Methodology

This study employed the Normalized Difference Vegetation Index (NDVI) through the Landsat satellite image and the Important Value Index (IVI) analysis with the vegetation analysis method. The NDVI is a widely used index to assess the health and density of vegetation, while the IVI analysis provides valuable insights into the diversity and abundance of plant species in a given area. By combining these two methods, this study aimed to provide a comprehensive understanding of the mangrove vegetation density and zoning pattern in Wonosari Village.

Results

The results of this study revealed that in 2002, the mangrove vegetation density was classified as dense, with NDVI values ranging from 0.3 to 0.4, covering an area of 415.61 hectares or 67.23% of the total region. In contrast, in 2022, the vegetation density increased to a meeting class, with an area of 495.53 hectares or 80.16%. Although there was an increase in dense vegetation density by 79.92 hectares, a very thick vegetation density decreased by 111.80 hectares. These findings suggest that the mangrove ecosystem in Wonosari Village has undergone significant changes over the past two decades, with an increase in dense vegetation density and a decrease in very thick vegetation density.

Mangrove Vegetation Zoning

The formation of mangrove vegetation at the location of this study is divided into three zones: open, intermediate, and back zones. The open zone is inhabited by species such as Rhizophora mucronata, Bruguiera Parviflora, and Avicennia Alba. The intermediate zone is characterized by the presence of Rhizophora mucronata and Bruguiera parviflora species, while the back zone, located on land, is dominated by species such as Xylocarpus granatum, Acrostichum aureum, and excoecaria agallocha.

Discussion

This study is crucial in understanding the dynamics of mangrove ecosystems, which are valuable to the environment. Mangroves not only function as coastal protectors from abrasion but also as a habitat for various fish species and other fauna, as well as a significant carbon container in climate change mitigation efforts. The zoning pattern found in Wonosari Village shows the diversity of species and varied vegetation density, reflecting the health of mangrove ecosystems in the area. Increasing the vegetation density area from 2002 to 2022 can be associated with rehabilitation and conservation efforts carried out by the local community and the government. This shows an awareness of the importance of maintaining the sustainability of mangrove ecosystems for the welfare of the environment and the community.

However, a very thick decrease in vegetation density is a concern. This decline can be caused by various factors, including climate change, pollution, and human activities such as encroachment and land conversion. Therefore, there needs to be a continuous effort to monitor and protect the mangrove ecosystem in this region.

Conclusion

By understanding the density and pattern of zoning mangrove vegetation, it is expected to provide recommendations for the management and conservation of sustainable natural resources, as well as improving the quality of life of the people around the mangrove area. The sustainability of mangrove ecosystems not only provides environmental benefits but also social and economic benefits for the surrounding community.

Recommendations

Based on the findings of this study, the following recommendations are proposed:

Continued monitoring and protection of the mangrove ecosystem: Regular monitoring of the mangrove ecosystem is essential to identify any changes or threats to the ecosystem.
Rehabilitation and conservation efforts: The local community and government should continue to implement rehabilitation and conservation efforts to maintain the health of the mangrove ecosystem.
Education and awareness: Education and awareness programs should be implemented to raise awareness about the importance of mangrove ecosystems and the need to protect them.
Sustainable management of natural resources: Sustainable management of natural resources is essential to ensure the long-term health of the mangrove ecosystem.

By implementing these recommendations, it is expected that the mangrove ecosystem in Wonosari Village will continue to thrive, providing environmental, social, and economic benefits to the surrounding community.
