The introduction of the rabbit has also strained the native wildlife of Australia. Rabbits have been blamed for the destruction of the eremophila plant and various species of trees . Because rabbits will feed on seedlings, many trees are never able to reproduce, leading to local extinction. One of the most common causes of overpopulation is the introduction of foreign species to a new ecological niche for which they have no natural predators. A famous example is the introduction of rabbits to Australia in the 19th century, where they had no natural predators.
