Abstract
Litter production was studied in mangroves of North-western part of Indus Delta. Litter fall in grey mangrove forests (Avicennia marina) was studied at two sites, Sandspit and Rehdri Goth. In the study, litter traps were used to monitor monthly rates of litter fall per m2 at two sites. The rates of litter fall were found to be 6.920 t/ha/year and 6.78 t/ha/year at the two sites which were within the range of other arid zone mangroves. Largest component of the litter were leaves (56.5 % and 59.6 %). While in the fruiting season, fruits were the major component. The greatest rate of leaf litter fall coincided with the rainy season. Litter turnover rate, Kt, was 16.53 at Sandspit where the residence time was 0.06 years. At the Rehdri Goth, the turnover rate was 12.42 while the residence time was 0.08 years.
