Different institutions present in the territory, can be sources of information on processes occurring at local and regional scale. Among them, rural schools might have homogeneous distribution and are in close contact with their natural, cultural and social environment. Also present trained staff with capabilities for incorporating new technologies. The objective of this study was to generate and evaluate the use of survey maps in rural schools, as a way to acquire information about the presence and location of 5 invasive alien trees species. For this purpose maps were produced (1: 75.000 scale) using Quickbird/ Landsat TM/ETM data available from Google Earth with ancillary information (locations, roads, references, legends, etc). The map form used for this survey has a legend an a instructive for its filling. With these maps, teachers were asked to fill with local information about the school neighbourhood. The information requested included identification of invasive alien trees in rural areas, abundance, reference area on which identification was performed, location of school, type of response, profession / occupation, age, among others. 52 map forms were distributed through the government post mail. 20 forms were answered, 80% of them recognized the presence of invasive species, pointing the specific area. Maps, generated byschools teachers, were validated with our own field data. This approach offers a methodology thatpromotes the inclusion of primary and high school education levels on science and technology for rural areas. Reviewing certain query criteria, it also could become a useful tool for the generation of information about the territory.
