    Management information
      Summary: In 1999, the database on species introduced into Poland was developed at the Institute of Nature Conservation, Polish Academy of Sciences in Krakow for the Ministry of the Environment. In 2003, thanks to a grant from the US State Department, part of the data was translated and made accessible on the Internet. In 2003-2005, as a result of cooperation between a group of experts, new species were included. In 2005, the Polish database became a part of NOBANIS http://www.artportalen.se/nobanis/ which is an important gateway to data on invasive alien species in Northern and Central Europe.
