Aims Seasonal litterfall production plays an important role in the carbon and nutrient cycling in forest ecosys-tems. This study examines the effects of micro-environmental factors on seasonal litterfall dynamics in the forests of Putuoshan Island, Zhejiang Province of eastern China. Methods The study covers five forest types, including Liquidambar formosana forest, Cinnamomum japonicum and Machilus thunbergii forest, Pinus massoniana forest, Cyclobalanopsis glauca forest, and Distylium gracile forest, in Putuoshan Island. We collected micro-meteorological data, and measured monthly litterfall in stands of the five forest types over one year. Redundancy analysis (RDA) was performed to determine the effects of micro-climatic factors on litterfall production. Important findings The average annual litterfall production ranged from 3.45 to 5.36 t·hm–2·a–1 across five types of forests, albeit no effect of forest types on the litterfall production. The partitioning of litterfall compo-nents differed among the five forest types. The seasonal litterfall production exhibited two contrasting patterns, i.e. double climax curve and triple peaks, and varied significantly among the five forest types. Moreover, the peak in the litterfall production mostly occurred in the windy months of the year, such as in April, July and December, which was consistent with the dynamics of wind speed. RDA results showed that components of litterfall production in different months were controlled by different micro-climatic factors. The total, leaves, fruits, andmiscellaneous litterfall productions were directly and positively affected by air temperature. Twig litterfall pro-duction was positively affected by the overstory wind velocity. Flower litterfall production was negatively af-fected by air humidity. In summary, forest types had no effects on litterfall production. However, variations in lit-terfall productions were explained by air temperature, air humidity, and overstory wind velocity in the forests studied.
