Detailed Site Description: 

This site is a focus study area of the German EarthShape initiative ( The climate setting is semi-arid/Mediterranean zone. This zone has sensitive vegetation with hydrophilous forests and evergreen sclerophyllous woodlands on shaded slopes and scrublands on exposed slopes; Jurassic granitoid lithology is present. Deeply weathered profiles are exposed along road cuts.

The La Campana National Park, as al four EarthShape study sites, is located in the Chilean Coastal Cordillera, between 25° and 40°S, which is one of the very few regions on Earth with uniquely rich conditions for quantifying biotic interactions with topography. The primary reasons for this are the north-south orientation of the region such that it captures a large ecological and climate gradient ranging from arid to temperate to humid conditions and, and it excludes glacial and periglacial environments to host mature soils. This gradient allows us to substitute time (in terms of IPCC climate change projections) with space (by using the prevailing north-south gradient in climate). Furthermore, the benefits for working in this area are:

  • Similar rock type. The selected regions are within 80 km of the coast and located in Cretaceous, Jurassic, and Permo-Carboniferous granitoid lithologies (granodiorite, tonalite, diorite, and monzodiorite composition). While the lithology is not identical in each region, the general compositions are similar and the best one could hope for from catchments separated over 15° of latitude (~1600 km distance) required for capturing a large ecological gradient. 
  • Tectonic uplift maintains topography and provides a topographic gradient for erosion on geological time-scales. The regional uplift rate south of 25ºS (the northern limit of our study area) is around 0.2±0.1 mm/yr and is the focus of ongoing intense study by the German led IPOC plate boundary observatory. 
  • Glaciation free catchments throughout the study area.  All catchments are located north of the maximum sea-level extent of the Patagonian ice sheet during the last glacial maximum. Although higher elevation (Andean) regions at the latitudes of study areas hosted Alpine glaciers, the rivers and catchments draining these areas are excluded from study. Rather, this program focuses on smaller, unglaciated, catchments located entirely within the Chilean Coastal Range (~100 to ~2500 km2 basin area).
  • A well-documented record of climate change. Marine, and lacustrine sediment records allow the reconstruction of climate change over the last glacial/interglacial transition.
