Dodo tree

Dodo trees are endemic to Mauritius.

Recently, scientists discovered that a species of tree on Mauritius was dying out. There were only 13 specimens left, and all of them were about 300 years old, dating from the time when the last dodo was killed. It was discovered that the dodos ate the seeds of the tree, and only by passing through the digestive tract of the dodo did the seeds become active and start to grow. After a while, it was discovered that the same effect could be accomplished by letting turkeys eat the seeds. The tree species is saved, and it is now called dodo tree.
