Today, Ginkgo biloba is a common street tree, found in cities all over the world. But believe it or not, it was once almost lost to extinction. This once global tree retreated into a tiny relic community, only found in a few valleys in China. But about 1,000 years ago, humans discovered ginkgo, thought it was beautiful and useful, and began to cultivate it. From there, in time, it spread across the planet again. This makes ginkgo arguably our oldest conservation project.
This episode of Gen Anthro tracks the entire journey of the ginkgo, from its emergence to its decline, to its resurgence. The story is also partly based on a book by Sir Peter Crane, former dean of the Yale School of Forestry, entitled Ginkgo: the Tree that Time Forgot.
