The Turkey Lakes Watershed (TLW) study is a federal, interdepartmental study established in 1979 to investigate the effects of acid rain on terrestrial and aquatic ecosystems. The 10.5 km2 watershed, located in the Eastern Temperate Mixed Forest on the Canadian Shield, has been the site of multidisciplinary studies on biogeochemical and ecological processes conducted across plot to catchment scales. The whole-ecosystem investigative approach was adopted from the outset and has allowed research to evolve from its original (and continuing) acidification focus to include investigations on the effects of climate change, forest harvesting and other forest ecosystem perturbations. The extensive scientific and support infrastructure allows for collection of a comprehensive data record essential for understanding long-term environmental trends. Data include atmospheric deposition, meteorology, stream hydrology and chemistry, soil, pore and ground water properties, understory and overstory vegetation, lake and outflow physical and chemical properties, and aquatic macroinvertebrate and fish community composition and abundance. These data have contributed to over 400 published research papers and graduate theses. The watershed has also figured prominently in many continent-wide comparisons advancing fundamental watershed theory. The knowledge gained at TLW has influenced pollutant emission and natural resource management policies provincially, nationally and internationally.

The central coast of Ecuador is a dry tropical forest. The seasonal N-S movement of the El Nino and Humboldt Currents creates a rainy season (De-May) and a dry season (June-November). Annual precipitation is approximately 700 mm, falling almost exclusively in the rainy period. The coast of Ecuador has been heavily deforested—as much as 98% by some accounts. The Cordillera del Balsamo, which lies to the south of Bahia de Caraquez is managed by local landowners and the international NGO: Global Student Embassy. The location is ideal for studying disturbance gradients across the tropical dry forest: a bioregion on which over 700 million people worldwide depend.
