STRUKTUR KOMUNITAS, ZONASI DAN KEANEKARAGAMAN HAYATI VEGETASI MANGROVE DI SEGARA ANAKAN CILACAP
ABSTRACT: Mangrove ecosystem
of Segara Anakan Cilacap has specific vegetation, function, and benefit. It was
dominated by Rhizophora, Bruguiera, Avicennia and associate vegetation such as
Nypa frutican. Stability of mangrove ecosystem can be seen by community
structure, zonation and diversity of mangrove vegetation. This research aimed
to analyze community structure, zonnation and diversity of mangrove vegetation
in Segara Anakan Lagoon. This research used survey method with cluster sampling
by stratified analysis. The Analyze of data used association analysis, zonation
analysis, richnes index, and Shanon Wiener index. This Research showed that (1)
Association index of seedling was dominated by index < 0.22 (lowest
association) with scored 46,67 % - 66.66 %, (2) Association index of sapling
also was dominated by index < 0.22 (lowest association) with scored 58,33% -
71.43 %, (3) Association index of tress also was dominated by index < 0.22
(lowest association) with scored 67,27 % % (4) Overlaping indeks showed
Aegiceras corniculatum has high overlap toward Nypa frutican (71 %) (seedling
stage) and Rhizophora apiculata to Avicennia spp (0,49) (sapling stage). (5)
Zonation of mangrove showed that Zone 1 as direct connecting zone with sea
which were dominated by Avicennia marina and Avicennia oficinallis. Zone 2 as
the middle zone which were dominated by Rhizophora mucronata, Rhizophora apiculata,
and Ceriops tagal. Zone 3 as direct connecting zone with island which were
dominated by Nypa fruticans, Acanthus ilicifolius, and Sonneratia casseolaris
(6) diversity index between 0.48 – 1.83 (low – middle).
