Villi Vyöhyke registered association is Finnish nature conservation focused organisation which was founded in Tampere in 2013. Founders of the association started planting meadow plants to road embankments and wastes in urban environments. Urbanization and structural change of agriculture has made many meadow plants endangered in Finland during 20st and 21st centuries. According to members planting wild plants in city area is in "gray area" according to Finnish law. City of Tampere has reacted positively to the functioning of the association. Villi Vyöhyke has established over 50 guerilla meadows in city of Tampere. The association operates mainly in Pirkanmaa region.
