The earthworm is also not native to North America and is an invading species. Before the introduction of the earthworm, the forests of the East coast had no undergrowth, but a thick matte of decaying leaves that was soft to walk on. The forests themselves were like great cathedrals that stretched for miles in every direction -- a huge open space with a canopy of leaves overhead, supported by columns of tree trunks growing out of a soft carpet of dead leaves.
