We have developed a Control-Impact design to analyze how the forest plantations modify the natural flow regime and determine the main effects on the function and structure of stream ecosytems . The design comprises 10 impacted and 10 control sitesin south-central Chile, in rivers draining from the coastal ranges and the Andes.

Map showing the distribution of land uses in the study area and the location of the study sites in 20 Chilean rivers.

In each site a set of indictars of stream health are measured including: River metabolism, nutrients, chlorophyll a, epilithic biomass, suspended solids, substrate composition and biotic communities, including macroinvertebrates and fishes. The first field campaign was carried out during the austtral summer, between the months of March and April 2018.
