National GIS Database of Invasive Plant Species

The spread of invasive plants is an extremely fast process. It is the biggest challenge for Hungarian nature conservation today. In addition to protecting the habitat of native species, it is also an important issue for the human health status to fight off the aggressively spreading invasive plants. It is only possible to solve this serious environmental and nature protection related problem with up-to-date spatial data of the extent of infestation in Hungary, and if we can identify the focal points of infection and the distribution directions of the species. This is the aim of the National GIS Database of Invasive Plant Species.

The maps were created based on databases and field observations by the Hungarian Ministry of Agriculture, Department of Natural Conservation, the 'Nemzeti Földügyi Központ Erdészeti Főosztálya' and citizen science, and by interpretation of EUROSTAT LUCAS (Land Use and Coverage Area frame Survey) database.

Invasive Plant Hunters

Crowdsourcing is an essential element of mapping invasive species. A mobile application for reporting these species that endanger natural habitats has become available in Hungary as well. Please contribute to the mapping of invasive species during your trips and hiking if you encounter any of these.

Our mobile application is available and easy to use for anyone, all you have to do is sign up via this link: https://developers.arcgis.com/ - then after successful registration, you can become a member of the "Özönnövény Vadászok Csoportja" [Invasive Plant Hunters] if you join the following group:

You need to download the Collector Classic app on your phone (from the Play Store or Apple Store) to submit the invasive plant you have saw and display it on our web map:

Become a member of our community on Facebook is! You can ask the experts on the subject both in English or Hungarian, ask for help with the mobile app and for the collection, or organize a nice hiking trip for mapping with other "Invasive Hunters"! Be a member of our community and work together against the spread of dangerous invasive species!
