Dinamika Vegetasi Mangrove Holosen Daerah Semarang Berdasarkan bukti Palinologi

Abstract

Palynological evidences (pollen and spores) have been used to study mangrove diversity and vegetation fluctuation at coastal zone sites at Muktiharja, Kemijen Semarang , province of Central Java. Data was collected in April 2nd to April 17th 2006 following transect method, for sediments sampling used surface subsurface sampling method (depth in 25cm).
