The present study was conducted to quantify the standing litter crop and litter fall production under dry tropical forests in buffer zone of Achanakmaar-Amarkantak Biosphere Reserve (AABR). Five major forest types viz., mixed forest, Sal Mixed Forest, Mixed Teak forest, Teak Mixed forest and Bamboo brakes were identified after floristic survey in the study area. Standing litter crop was recorded by randomly laying three 0.5 x 0.5 m sub quadrates on forest floor in each marked sample quadrate (20 x 20 m) of a forest type. In total, standing litter was collected in 15 sample plots (3 locations within quadrate x 5 quadrates). Litter fall transferred to the forest floor was measured in different seasons by randomly laying three litter traps (each 50 x 50 x 50 cm size) in each sample plot under different forest types. In total, litter fall was also recorded in 15 sample plots similar to standing litter. Results revealed that total standing litter varied from 0.48 Mg ha-1 to 2.49 Mg ha-1 in different forest types. It was highest in Mixed Forest and lowest in Bamboo Brakes. The standing litter in different forest types was in the order: Mixed Forest > Mixed Sal Forest > Mixed Teak Forest > Teak Mixed Forest > Bamboo brakes. The litter mass contributed by different components was in the order: leaf > wood > bark. For total standing litter, the leaf litter contributed from 52.1% to 91.7%, wood from 5.8% to 38.1% and bark litter from 1.4% to 12.1%. The total annual litter fall in different vegetation types ranged from 0.86 to 3.52 Mg ha–1 yr-1. It was highest in Mixed Sal Forest, while lowest in Bamboo Brakes. Among three seasons, the litter fall was highest in winter followed by summer and rainy seasons. Leaves contributed to maximum followed by wood and bark for total litter fall in different seasons. For total litter fall, in summer it ranged from 29.2% to 41%, winter from 34.9% to 41% and rainy from 23.3% to 31.2%. The study discussed role of management practices for improving the litter production in degraded forest types in buffer zone of AABR.
