Abstract

The Tiris mangrove forest, Rhizophora apiculata-R. mucronata community, grows in the area with highly human induced stress and typically by silty clay substrate. The litterfall studies in Tiris, Indramayu (Lat. 6º 10'-7º 49' S and long. 107º25'-108º25' E), using litterfall trap and plot techniques indicate that the mangrove forest is very productive. Litter productivity, as measured by litter trapping of a R. apiculata dominant mangrove forest at Tiris is 1,290.95 dry g/m2 /year, and estimated as 12.90 dry t/ha/year and leaf shared is 40.70%. This is a high value when compared with the mangrove forests in the Indo-West Pacific and/or Malesian regions, and even with R. mucronata plantation in Tritih, Segara Anakan, Cilacap (Lat. 7º 41'-7º 45' S and Long. 108º 46'-109º E). Correlations between litter components with rainfall, number of rain-day, wind run, mean maximum temperature, mean minimum temperature, and mean monthly temperature, and relative humidity are calculated for understanding their role in litter production. These correlations are discussed and it is suggested that seasonality of mangrove need to be considered in terms of whole tree physiology rather than isolated environmental factors. Also, the high production of litter means an important contribution to support food-webs of many marine organisms. The results suggest that, in terms of litter, the mangrove forests in Tiris may be one of the most productive forest types in Java.

Abstract

Indonesia's mangrove resources (soils and waters, flora and fauna, and as an ecosystem all are called as mangrove biodiversity) are growing in importance. As a consequence of past and present human utilization the mangrove resources have been depleted. Keen competition for use of the mangrove resources is apparent and is likely to intensify in the future. This policy document stresses the importance of mangroves for the Nation and the need for the Government to manage and protect them. A set of basic principles for the management and protection of mangroves is provided, together with an outline of some actions which local and central governments (Pemerintah Pusat dan Daerah) should take up in order to achieve a balance between the use of mangrove resources, their conservation and long term national development.

Abstract

Undergrowth vegetation analysis in the old coconut stands in the Pari Island wasundertaken, to determine the structure and floristic composition in relation with their habitat characteristics. Physiognomically, the undergrowth vegetation typified by grasses community with Ischaemum muticum (Importance Value: 122.94%) and Imperata ylindrica (Importance Value:  5.45%) to be a dominant and co-dominant species,respectively. Floristically, the grasses community consists of 27 families along with their 56 genera and 58 species. Amongst those, only 15 species belong to a weed component and can be classified as principal and common weed species in the agricultural land in Indonesia. The grasses community has four common families in term of their highestnumber of species, viz Compositae, Euphorbiaceae, Leguminosae and Poaceae.Based on the ordination technique of Principal Component Analysis (PCA) three distinct groups of the vegetation component can be recognized as (i) pes-caprae formation, (ii)Calophyllum formation and (iii) transition community zone. The spatial distribution of prevalent species in relation with their habitat characters was discussed. Generally, the grasses community can be classified into secondary vegetation of the small island.Keywords : Vegetasi bawah, pohon kelapa, kenanekaragaman jenis, mitigasi,pengelolaan terpadu pesisir dan laut, Pulau Pari, Teluk Jakarta
