National Invasive Species Awareness Week: Callery Pear/ Bradford Pear (Pyrus calleryana)

Today’s invasive species is an excellent example showing that some invasive species LOOK nice, but the negative impact they have on our environment isn’t worth it (especially when there are native species that look just as pretty!).
