Estimating of interception loss, stemflow and throughfall in a natural stand of oriental Beech (Shastkalateh forest)

In this study, measurements of precipitation, throughfall and stemflow fluxes were conducted from November 2005 through November 2006 within a natural stand of oriental beech (Fagus orientalis Lipsky) in district 1, Shastkalateh, Hyrcanian forests.Total precipitation in this period was 827.1 mm year−1. A sample of 31 trees was randomly selected. Throughfall and stemflow of each tree were collected after every precipitation. Throughfall and stemflow fluxes represented 40% and 0.3% of the precipitation, implying that interception loss (the difference between precipitation and sum of throughfall and stemflow) was 59.7%. Relation between throughfall, stemflow and interception with precipitation was invistigaited.
