Endangered & Lost Species

Environmental Art Projects & Events

At ONCA we use art to explore stories of extinct and critically endangered species and ecological communities.

The Story of ONCA

In 2011, the idea for ONCA emerged when our founder Laura Coleman wanted to find a way to platform stories about the issues that affected the animals and humans who she met at a small wildlife refuge in the Bolivian jungle. Since opening in 2012, ONCA has become a space for exploring stories about extinctions that acknowledge and pay proper attention to the related human experiences of injustice or oppression. We continue to host a range of events that support the remembering of what has been lost, celebrations of and commitments to what remains, and the development of creative and practical solutions. Some of the exhibitions and events we’ve curated and supported include:

What’s On

Remembrance Day for Lost Species at ONCA

Established in 2011, Remembrance Day for Lost Species (Lost Species Day or RDLS) is driven by a growing coalition of artists, educators, scientists, historians and campaigners including ONCA. The day invites people to engage in whichever ways feel manageable – whilst pointing towards the need for spaces of systematic critique and acts of reparation. Part of the project’s aim is to highlight the interconnected norms and practices that harm diverse ecosystems and humans alike.

Since 2011, ONCA has joined groups in the UK and internationally to meet on November 30th and hold memorials for extinct species. Brighton remembrance events have ranged from a burial at sea for the Great Auk (extinct 1852) to a procession for the Caribbean Monk Seal (extinct 1952).
