The outdoor control trees have finally been planted!
Thanks to #smithsonian NHRE intern Zev Brook for help digging another massive hole, and then help in filling it right back up with topsoil and mulch. That feels great!

Ginkgo Elevated CO2 Experiment
Fossil Atmospheres
We are growing Ginkgo biloba plants under ambient (400 ppm) and elevated CO2 levels (600, 800, and 1000 ppm).
Our experiment helps us estimate CO2 levels in fossil atmospheres using fossil Ginkgo leaves we collect from the geologic record.
