Since 2004, Brooklyn-based contemporary artist Rachel Sussman has researched, collaborated with biologists, and braved some of the world’s harshest climates from Antarctica to the Mojave Desert in order to photograph the oldest continuously living organisms on Earth. This includes plants like Pando, the “Trembling Giant,” a colony of aspens in Utah with a massive underground root system estimated to be around 80,000 years old. Or the dense Llareta plants in South America that grow 1.5 centimeters anually and live over 3,000 years. This is the realm of life where time is measured in millennia, and where despite such astonishing longevity, ecosystems are now threatened due to climate change and human encroachment.
