The bison project started as a partnership between PWN, ARK Nature, Stichting Duinbehoud, Stichting Kritisch Bosbeheer and FREE Nature. The project team works together with Ekogron, and with the European Bison Friends Society based in Poland.
In 2012, main partners PWN and ARK Nature decided to continue their efforts in the pilot project and extended it untill 2017.
The project is supported by Prince Bernhard Cultuurfonds, Province of North-Holland, VSB Fonds, Stichting ANO Fundatie and the Dutch Postcode Lottery. Via ARK, the Dutch Postcode Lottery supports the bison project on a yearly basis.
