Arcturos is a prominent non-profit environmental organization founded in 1992 in Greece, dedicated to the protection of wildlife and their natural habitats both locally and internationally. It was established in response to the urgent need to address the increasing problem of bear and wolf captivity. Over the years, Arcturos has developed a comprehensive framework of actions aimed at wildlife preservation, which includes various initiatives in environmental education, scientific research, and species rehabilitation.

The organization operates specialized facilities such as the Bear Protection Center in Nymfaio and the Wolf Sanctuary, focusing on the care and rehabilitation of several endangered species including bears, lynxes, and wild goats. Arcturos also actively promotes volunteer opportunities, encouraging community engagement in conservation efforts and providing educational resources. Their mission is encapsulated by the belief that we do not own the Earth; rather, we, in tandem with wildlife, share this planet. Through innovative programs and community involvement, Arcturos works tirelessly to secure a sustainable future for Greece's natural heritage.
