Information
The Korvaamattomat exhibition will be on display in the Winter Garden at Tampere Hall from 7 to 21 October 2026. Admission is free, and the exhibition is open during Tampere Hall’s opening hours.
How does the sea otter help slow climate change? Why is the European spruce bark beetle, commonly regarded as a pest, an important and beneficial species in natural forests, supporting hundreds of other species? These are just some of the questions explored in Korvaamattomat – näkymiä maailman avainlajeihin (Irreplaceable – Perspectives on the World’s Keystone Species), a joint exhibition by illustrator Janne Toriseva and non-fiction author Juha Kauppinen, opening in the Winter Garden at Tampere Hall in October 2026.
Through striking illustrations and animations, accompanied by concise yet insightful texts, the Korvaamattomat exhibition introduces species considered vital to the Earth’s ecosystems – so-called keystone species – and the countless fascinating relationships they have with other living organisms.
The Korvaamattomat exhibition has previously attracted more than 200,000 visitors at numerous venues, including the Finnish Museum of Natural History in Helsinki and the nature centres at Koli and Oulanka.
The exhibition is based on the illustrated non-fiction book Korvaamattomat – kertomuksia maailman avainlajeista (Siltala, 2023). The exhibition and the book have received funding from the Kone Foundation, the Finnish Cultural Foundation and the Finnish Illustration Association.
