In June 2026, we tackled invasive alien plant species (IAPS) across all 23 of Poland’s national parks, six landscape parks in the Warmian-Masurian Voivodeship, and three provincial cities, inviting primary and secondary school students to join the effort. We shared knowledge about invasive alien plants, raised awareness of the dangers they pose, taught students how to identify them in the field, and – most importantly – removed them from specific locations.
In the Warmian-Masurian Voivodeship, the IAS Control Day took place in the following areas:
Masurian Landscape Park,
Welski Landscape Park,
Elbląg Upland Landscape Park,
Romincka Forest Landscape Park,
Iława Lake District Landscape Park,
Dylewskie Hills Landscape Park,
and in the city of Olsztyn, with the participation of Primary School No. 3.
The event featured competitions, an outdoor game, talks, presentations, field trips, and the active removal of Himalayan balsam. A total of 335 children and young people from seven schools took part in the campaign across the Warmia and Masuria region, alongside teachers and staff from landscape parks and forest districts. We extend our sincere thanks to everyone for their commitment and concern for the survival of native species—which are vital for maintaining biodiversity and ecosystem function.
The IAS Control Day initiative, launched this year as part of action T.8.4, will be rolled out over the coming years.
