Abstract

Mangrove forests form due to vegetative distribution along coastlines with varying growing conditions concerning substrate, freshwater intake, and oceanic currents. These disparities facilitate zoning and subsequent distinct growth patterns. The research objective was to identify the zoning structure of mangrove ecosystems in Lampung Timur Regency, Lampung Province, Indonesia. The degradation of mangrove forests in Lampung Timur Regency was thought to be caused by anthropogenic activities and inappropriate zoning patterns. Concerning data collection, the cluster sampling method was employed, which was selected based on the preliminary study's findings that the mangrove status in the study area exhibits a variety of substrates, freshwater supply, and strong ocean currents. There are five clusters on the study site, with each cluster containing sample plots measuring 10m x 10m. The sampling method employed a striped path starting from the outermost part of the mangrove ecosystem, with the number of plots in each cluster dependent on the thickness of the mangrove vegetation. A regional map and GIS applications were used for mangrove zonation mapping, and the factors influencing the zonation of mangrove ecosystems were analyzed descriptively. The research findings demonstrated that the mangrove ecosystem located in Lampung Timur comprises three distinct zones: the outer zone, the middle zone, and the terrestrial zone

Abstract

Ekosistem mangrove memiliki keunikan yaitu adanya zonasi yang khas dan membedakannya dengan vegetasi terestrial. Penelitian ini bertujuan untuk mengetahui pola zonasi mangrove di Rawajitu, Kabupaten Tulang Bawang, Provinsi Lampung. Penarikan sampel dilakukan dengan metode klaster sampling, hal ini didasari pada kenyataan bahwa kondisi mangrove pada lokasi penelitian memiliki keragaman dalam hal substrat, pasokan air tawar, dan kondisi arus laut. Pada masing-masing klaster diletakan plot contoh berbentuk garis berpetak yang diawali dari bagian terluar yang paling dekat dengan lautan sampai dengan daratan. Data ditabulasi dan dikelompokkan berdasarkan spesies penyusun vegetasi utama pada setiap zona. Analisis data dilakukan secara deskriptif analitik. Hasil penelitian menunjukan bahwa hutan mangrove di Rawajitu tergolong pola zonasi lengkap yaitu zona luar dengan vegetasi penyusun Avicennia marina, Sonneratia caseolaris, zona tengah dengan vegetasi penyusun Rhizophora mucronata, zona nipah dengan penyusun Nypa fruticans dan vegetasi penyusun zona darat (Excoecaria agallocha dan Hibiscus tiliaceus).
