Statistically analyzing surveys from different parts of Amazonia suggests that there are 16,000 different species of trees in the whole forest.

1/3 of these species are estimated to have under 1000 members. Practically speaking, there is no chance of identifying them.

Think of that when people talk about preserving species outside their ecosystems, or perhaps preserving tissue or DNA. If the Amazon forest dries out and burns up, it will never come back.
