Buckthorn - An Alien Invader

Buckthorn - An Alien Invader:

European or common buckthorn (Rhamnus cathartica) is an invasive species that is crowding out many native plants in our woodlands. This fast growing treelike shrub not only blocks out light and produces enzymes that destroy native plants, it also can be a host for crown rust spot which destroys soy bean crops and helps the growth of Asian lady beetles. Working together, we can help exterminate this alien invader.
