Abstract
The present paper elucidates the pattern of leaf-fall in dominant tree species and quantifies the total annual input of litter in a mixed oak-conifer forest of Kumaun Himalaya. In addition, concentration of selected nutrients in various litter species and their annual return to the forest floor are examined. Among the six dominant tree species, the leaf-fall in Aesculus indica was restricted to the period May-October, while the rest of the species continued to shed leaves throughout the year. at variable rates.The total annual input of litter was estimated.at 606.1 g.m-2; of which the tree litter accounted for 553.3 g.m-2. The annual nutrient return through litter fall amounted to (kg.h a-1): 73.8 nitrogen, 150.3; calcium, 0.4 phosphorus, 369.3 ash, 1 709.4 water soluble compounds and 659.5 total available carbohydrates. The nutrients, showed an annual replacement rate of 54-65%.
