Carbon and energy transfer that take place in forest ecosystems are directly related to the amount of biomass produced by the trees as a result of photosynthesis. Another important task of trees is to to transfer their vegetative components that have expired through the aging process to the soil surface. This structure accumulated in the soil is called litter. Therefore, the change in the net primary production of the plants also affects the annual amount of litter. Litter, defined as the collection of dead organic matter (consisting of foliage, fermentation and humus layers), is one of the main sources of organic matter in the soil. Variation in litter is important for biomass studies. In a forest ecosystem, most of the nutrients are obtained through litterfall. For this reason, determining the litterfall and litter layers in such ecosystems constitutes essential parameters for the global carbon cycle and sequestration. This study was carried out in the Belgrad Forest, located in the north of Istanbul/Türkiye. The foliage layers of mixed-stand litter were collected during regular field visits. The aim of this study is to provide a basis for evaluating accumulations in the foliage layer with long-term observations by determining the amount of various components.
According to the results obtained from 12 sample areas located in the Atatürk Arboretum, a natural extension of the Belgrad Forest, an annual average of 658.28 g/m2 of litter was accumulated in the foliage layer. The oak, beech and hornbeam leaves in the sample areas were found to be 15.42, 20.54 and 2.67 gr/m², respectively. Among the other components, branches were 96.09 g/m², acorns were 423.61 g/m² and Hedera helix leaves, the main herbaceous species in the area, were observed to accumulate in the foliage layer annually at an amount of 49.38 g/m².
