Ginkgo can be commonly found in backyards and in parks, but it is close to becoming extinct in the wild. One of the mysteries surrounding the tree is their ability to live for over 1,000 years. A recent study has found that the trees secrete protective chemicals that help fend off disease, and that they lack a programmed inevitable deterioration mode after reaching their prime. Without having the age-defining program that triggers a natural decline, the ginkgo tree’s only other natural predator are the diseases they are built up against. Ginkgo is on the brink of extinction in the wild largely due to logging and being mainly confined to China.
