Abstract: The aim of this
study is to understand the density and litterfall productionof riparian plant
dominant DAS Siak in the Belading Village, Sabak Auh Sub-Regency, Siak Regency,
Riau. This reseach was conducted on Mei to Juni 2009.Method used in, this research
was a purposive sampling method. There were onestations, and there is 18

dominant were Hisbiscustiliceus (0,25). Litterfall production of riparian plant
dominant DAS Siak isHisbiscus tiliceus (203,1gr/m2/month) dan Beilschmiedia roxburghiana
