Our work photographing plants and developing identification services commenced back in the 1990s. The collection of this material has also given rise to a TV series and several books. NatureGate’s research and development working group was set up in 2006, within the University of Helsinki’s department of teacher education, led by Professor Mauri Åhlberg. For more information about the people behind NatureGate see our web magazine (currently only in Finnish).
