The total number of Ginkgo trees in the world will never be precisely known. One reason is that almost no country in the world does not do accurate cadastre of Ginkgo trees, broken, whether by gender, age or otherwise. In addition it is almost impossible to track the population of these plants since the last decade to almost the expansion of cultivation of Ginkgo. However, there are certain records in some countries for especially important and valuable trees. But that information will be collected in future successive and segmental in areas of many countries.
If we take into account the Ginkgo plantation in America, Europe, China, Japan and elsewhere and the existing plant we can say that the number of Ginkgo plants today is measured in millions. Single lists was best edited and introduced by Cor Kwant from the Netherlands (on the website “The Ginkgo Pages”), and there are a number of other websites around the world which state the views of individual plants, sometimes even the leaves. Besides we also have a somewhat older and more recent published literature in which one can reach the data on the approximate number of plants in a particular country or a region.
At the end of this section there is a list of literature from which we can learn more about the prevalence of Ginkgo in the world, and Hardiness Zone Maps in the World, from which you can see which areas in the world is suitable for growing Ginkgo.
