| Summary: | Habitat factors greatly affect the composition of the mangrove ecosystem. Changes in habitat quality may result on a shift of the type of plant mangrove ecosystem composition. This study aimed to determine the spatial distribution patterns of mangrove vegetation based on the characteristics of the habitat in the mangrove area in Pemalang District. The method used for data collection was the combination of transect method and plot sampling. The results showed that the spatial distribution of mangrove habitat factors at each observation station formed three clusters with different characteristics. Cluster 1 was characterized by low levels of pH, dissolved oxygen, and temperatures, as well as high values of mud thickness, and salinity. Cluster 2 was characterized by the low amount of dissolved oxygen, salinity, and mud thickness and high levels of temperature and pH. Cluster 3 was characterized by low values of pH, salinity, and mud thickness but high amount of dissolved oxygen and mild temperatures. The spatial distribution of mangrove species based on the characteristics of the habitat factors formed three clusters. Cluster 1 were Rhizophora mucronata Lam. and Sonneratia alba Sm. species as the habitat characteristics were mild temperatures and high amount of dissolved oxygen. Cluster 2 were Acanthus ilicifolius L., Avicennia alba Blume, and Rhizophora apiculata Blume with habitat characteristics were moderate levels of mud thickness, pH, dissolved oxygen and salinity. Cluster 3 was Avicennia marina (Forsk.) Vierh. as its habitat characteristics were high values of pH, salinity, temperature, and mud thickness. |
