8 Endangered Plant Species

We often post about endangered animals, but plants can go extinct as well. Plant species' fortunes are affected by the actions of humans and other animals. Consider the strange case of the plant pictured here known as Cabbage on a Stick:

Cabbage on a stick is pretty much what it sounds like: a tuft of leaves that looks like a head of cabbage sitting on top of a thick stick. It's also known as alula. In the wild, this plant is only found on the Hawaiian island of Kauai and without the work of botanists, it would be extinct. Because the only insect that could pollinate the cabbage on a stick, a type of hawk moth, doesn't exist anymore, the plant species can only reproduce if humans hand-pollinate it. Botanists repelled down cliffs to reach the existing alula, pollinate it, and bring some back with them to grow in nurseries.

Other plants are endangered because of over harvesting, environmental encroachment, or even poaching. Link
