LechuSA (Land Ecosystem Change Utility for South America) is a tool that helps to identify and understand functional changes of South American terrestrial ecosystems during the last 25 years, and is a space for discussion and collaboration between researchers studying those changes from different regions and perspectives.

Change maps show possible hotspots according to different functional variables. These maps are useful bases for participant’s contributions, rising hypotheses and evidences on the nature and causes of changes, allowing the enhancement and up-date of maps. Contributions can be supported by existing publications and integrated to a data base linked to hotspots. Combination of contributions and publications would lead to get a synthesis on changes in the continent. Besides, we will provide different utilities, like the extraction of temporal series of satellite information on areas for users´ interest.
