Have you ever heard of zebra mussels? Or purple loosestrife? How about gypsy moths? There is thing that all of these species have in common – they are all invasive species. Invasive species are non-native species that overrun an environment where they have been transplanted. Throughout history people have intentionally and unintentionally moved species from their original environments to new ones. These non-native plant and animals are not always harmful, however, some of these new species cause problems when they outcompete the native species. Explore the world of invasive species with Project Learning Trees “Invasive Species”! February 26 to March 3 is National Invasive Species Awareness Week.
