Archangel Ancient Tree Archive has created 75 ancient Redwood tree clones using Redwood stumps as old as 3,000 years. Founded in 1994, the California nonprofit group managed to create a tree embryo, then raise it for 2.5 years, before planting it in the Presidio forest refuge near San Francisco in December 2018.

The group’s stated mission is to reforest vulnerable ecosystems with a living archive of ancient tree specimens, thereby preserving and restoring some of the diversity of “old growth” forests and sequestering more carbon.
