The average annual fall of leaf-litter was estimated as 1.04 kg. dry weight per Kandelia bush and the total litter fall from bushes on the bunds surrounding the kei wai as 1,430 kg.; on a conservative estimate 40% of this (572 kg.) entered the water. Bushes growing on the islands produced at least the same quantity of litter as those on the bunds and all of it would enter the water. Consequently, the total amount of Kandelia leaf litter entering the water would be at least 2,000 kg. per annum or about 540 kg. per hectare of open water. Litter fall occurred mainly in months of July to November (Table 2). Smaller amounts (estimated as 950 kg.) of flowers, "fruit" or "droppers" and other debris would also enter the water.
Similarly, the aerial standing crop of Phragmites on the bunds was some 280 g m2 dry weight. On the assumption that the entire aerial standing crop died each year and that 40% of it entered the water...
