Dendrogram Zonasi Pertumbuhan Mangrove Berdasarkan Habitatnya di Kawasan Rehabilitasi Pantai Utara Jawa Tengah Bagian Barat
Abstract: The growth of
rehabilitated mangrove, although planted at the same time, shows differences in
terms of density and height growth. Such condition is visible in the North
Shore of Brebes, Tegal and Pemalang Regency.
The research result shows that mangrove growth planted in 2001 on the
North Shore of Brebes, Tegal and Pemalang Regency is not apart from several
factors, among others are its habitat physical-chemical factors. The result of
regression correlation analysis shows that the habitat factors which play an
important role in the vegetation density are salinity, temperature and plankton
population. Meanwhile, the most dominant factor which determines the vegetation
height growth is salinity and phosphor. The combination role based on its
habitat shows that mangrove growth in Brebes Regency on proximal (1P) and
medial (1M) zone and the one in Pemalang Regency on proximal zone (3P) has the
shortest cluster, so that those research locations have similarity on
vegetation growth and its habitat factors. Meanwhile, the proximal (2P) zone in
Tegal Regency is similar with the medial (2M) zone. Mangrove growth on distal
zone in Tegal Regency has less good growth parameter and habitat factors
compared to that of in Brebes and Pemalang for containing more sand.
From the research result, it can be concluded that the existence of
habitat factors salinity, plankton population and phosphor have to be taken
into consideration if a mangrove area will be rehabilitated/planted especially
using Rhizophora mucronata seedlings. In order to reach the maximum
achievement, one thing which has to be taken into consideration is the habitat
clustering of the planted area, especially in Brebes, Tegal and Pemalang
Regency area.
