Previous researches indicated that in-stream large wood (LW)
depended on the characteristics of the riparian vegetation. This
is the first study about LW abundance, longitudinal distribution
and sediment trapped by large wood structures comparing two
stream segments in catchments with contrasting land use, located
in the Coastal Mountain Range, Southern Chile. One such
catchment (Vuelta de Zorra) is covered mainly by native forests
and the other (Pichún) runs under productive plantations. In a
stream segment of each catchment the riparian vegetation was
characterized, each LW piece was measured and geo-referenced and
the channel morphology was defined. Vegetation along the Vuelta
de Zorra channel corresponded to an adult second growth forest
