In response to the climate emergency, artists Ackroyd & Harvey have installed Beuys’ Acorns, a group of 100 oak trees, on Tate Modern’s South Terrace Beuys’ Acorns takes its inspiration from the artist and co-founder of the German Green party Joseph Beuys, whose centenary it is this year. From 1982 to 1987, Beuys and his helpers planted 7,000 trees alongside 7,000 basalt rocks in Kassel, Germany. Called 7000 Oaks this ‘social sculpture’, as Beuys called it, permanently altered the cityscape, connecting art to the emerging climate movement.

In 2007, British artists Ackroyd & Harvey travelled to Kassel and collected acorns from the original oaks. A hundred of the now-grown trees will come together at Tate Modern, creating a living sculpture – a place for gathering and for rethinking our connections with nature.

At Tate Modern, Beuys’ Acorns will sit directly above Beuys’s work The End of the Twentieth Century, installed in the Tanks below. Its basalt stones are derived from the same rocks used in 7000 Oaks, reuniting the two elements from Beuys’s original piece.

Ackroyd & Harvey are co-founders of Culture Declares Emergency, which launched in April 2019. The movement aims to create strategic plans for individuals and organisations – including Tate – to help sustain the planet.

Every effort has been made to minimise the environmental impact of this installation. Materials were brought to site by bicycle. Care has been taken to use local existing resources, avoid single use plastic and chemicals. Wherever possible materials will be reused or recycled at the end of the display.
