Keanekaragaman Jenisdan Struktur VegetasiMangrove di Desa Sidodadi Kecamatan Padang Cermin Kabupaten Pesawaran, Provinsi Lampung

Abstract

ABSTRACT Both diversity and vegetation structure of mangrove at the Village of Sidodadi, Disctric of Padang Cermin, Regency of Pesawaran, Lampung have been studied. This study applied transects across beach line covering 1.83ha areas and used quadrats as sampling units in collecting mangrove data. The result showed that Sidodadi mangrove forest contained 22 mangrove species which consisted of 10 major mangrove, 4 minor mangrove and 8 associates species. Shannon-Wiener Diversity index was H’= 0.77 (seedling), H’=0,83 (sapling) and H’=0.96 (tree). Meanwhile, mangrove at all level of growth was dominated by both RhizohoraapiculataBlume and Rhizophorastylosa Griff. According to important value index (IVI), Rhizohoraapiculata Blume was dominant at level of tree, however Rhizophorastylosa Griff. was prevailing at sapling and seedling, as it IVI values were 104.57% and 68.60%, respectively.
