The Advanced Ecological Knowledge and Observation System from the Terrestrial Ecosystem Research Network (TERN AEKOS) focuses on ecological plot data that are generated by land-based ecosystem projects that use survey, monitoring and experimental studies to collect raw data on plants, animals (including traits) and their immediate environments at the same location. Plot data are observations sampled by using scientific techniques such as quadrants, grids, transects, animal trap arrays and other structured sampling techniques.
