<![CDATA[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.]]>
