It may sound far fetched, but we have it under good authority that art is starting to grow on trees. They line our parks, maintain our industries and sustain our existence. And trees’ role in public installation art is far from revolutionary. One need only bark back to the artist and environmental activist Joseph Beuys’ 7000 Oaks, a project first publicly presented in 1982 at the Documenta 7, it was part tree art, part gesture towards green urban renewal. 

As the conversation around conservation and climate change ramps up, trees appear to have become the medium of choice to engage, educate and inspire audiences. Through tree art, with ambitious large-scale installations, artists are confronting our complex relationship with the natural world. They are also proving that art can be a living, breathing material, and serve a higher purpose than concept or aesthetics, as a vehicle for social change. These contemporary artists appear to be barking up the right tree: 

Artist: Klaus Littmann 
Location: Münsterplatz, Basel

In 2019, Swiss art interventionist Klaus Littmann stunned the arts and cultural scene when he filled a football stadium in the town of Klagenfurt with a full-grown forest. Inspiration for the project, aptly titled For Forest, began three decades ago, when Littmann caught sight of The Unending Attraction of Nature, a futuristic illustration by artist and architect Max Peintner. It pictured a stadium packed with spectators gazing towards a fully-grown forest. To some, this might have been an intriguing fantasy; to Littmann, it was an invitation to make it a reality.

Now, in Basel, Littmann is staging his two-part follow-up project. Whereas a football stadium was filled with 299 trees in Klagenfurt, Arena for a Tree, sited on Münsterplatz, features a single tree as the sole stage actor. This walk-in tree art installation, where a solitary tree sits within a circular basket-like structure, can invite 50 people inside at a time and will be open until 24 May. ‘Nature itself is a total work of art – it deserves an homage once in a while,’ says Littmann, who is also staging a concurrent exhibition at Kulturstiftung Basel H Geiger, titled ‘Tree Connections’. The show, which runs until 11 July, features 75 works by 45 artists, and seeks to demonstrate the diversity of artistic engagement with nature.

Artist: Ackroyd & Harvey
Location: Tate Modern, London 

Outside Tate Modern is a living, breathing homage to the environment, and Joseph Beuys, 100 years since the artist’s birth. Beuys’ Acorns is a living sculpture where visitors can reconnect with art after lockdown, rethink their relationship to nature, and reflect on art, activism and the climate emergency. ‘Ahead of welcoming visitors back inside Tate Modern, we’re thrilled to be unveiling this important and timely outdoor installation addressing the urgent need for global climate action. Alongside our ongoing work to make Tate a more sustainable organisation, we also want to give a platform to artists, like Ackroyd & Harvey and Joseph Beuys, who inspire wider public conversations and spark positive change in us all,’ says Frances Morris, director, Tate Modern

The project, which began in 2007, takes direct inspiration from Beuys’ 7000 Oaks – City Forestation Instead of City Administration, in Kassel, Germany, a project that sought to raise ecological awareness, aid mental wellbeing and encourage all who encountered it to plant trees. As Ackroyd & Harvey explain, ‘We feel a strong sense of protection towards these young trees in a time of enormous planetary instability when destruction of the world’s forests increased sharply last year. Beuys called for the world to become a big forest: Beuys’ Acorns declares a climate and ecological emergency and calls for a revolution of love in our relationship with nature.’

Artist: Maya Lin 
Location: Madison Square Park Conservancy, New York

Ghost Forest is both an art installation and a call to action. It draws on the eponymous and increasingly prevalent phenomenon whereby vast tracts of forests perish due to climate change. For the project, artist, architect, and activist Maya Lin and Madison Square Park Conservancy have created a grove of 49 spectral white cedar trees which loom large, and stark, amid the park’s verdant landscape. Stripped back and leafless, the trees are a haunting reminder of a very real problem as the natural world continues to be ravaged by climate change-related causes.

Lin sourced trees for the installation from an area in New Jersey’s Pine Barrens that has suffered extreme deprivation. In conjunction with the project, Lin and the conservancy have devised a series of public programmes that support conversation and public action against climate change – from the planting of 1,000 trees and shrubs around New York City to talks with leading voices in the field and a series of nature-inspired musical performances curated by Carnegie Hall and performed from within the installation during the summer.

Artist: Superflux 
Location: Museum of Applied Arts (MAK), Vienna 

Invocation for Hope is an immersive installation by Superflux that imagines a new vision for our planet’s future. Commissioned for the Vienna Biennale for Change 2021 and created by the London-based design agency founded by Jon Ardern and Anab Jain, the installation is a vast indoor forest that seeks to address the climate crisis with hope. In collaboration with the forestry and fire departments of Austria’s Neunkirchen region, Superflux salvaged more than 400 trees that had been burnt in a recent wildfire and transplanted them to MAK.

As Jain explains, ‘We want to foreground how we’re part of a larger ecology rather than the masters of nature. Within this complex ecosystem, we all play a part in mutual survival and evolution. Without it, we cease to exist.’ The piece addresses the potential of a ‘more-than human’ future – a post-anthropocentric planet in which humanity is just one component of a dynamic and multifaceted ecosystem. ‘Climate change is not a problem we can “solve” but rather a predicament we must navigate with responsibility and urgency,’ says Ardern. Invocation for Hope will be on view as part of the Vienna Biennale for Change 2021 at MAK from 28 May to 3 October 2021. §
