Research Summary
: Megan S.
My research was a little difficult; it had good days and bad days but it all worked out. Sometimes I couldn't find what I need to find. The most surprising thing that I found was that the autumn olive is edible but most people don’t like it because of the tart taste. I think the most important thing that I learned is that it re-sprouts vigorously after cutting or burning. This is important to know so if you do came to see an autumn olive you will know not to cut or burn it, but to dig it up if possible.

    Location and Movement
    Origin/ Native Range
     Native to Japan, China and Asia.
     It was brought to the U.S in 1830. Autumn olive was wildly planted by human for wildlife habitat,
     mine reclamation, and shelter belts. 
    Spread of Species
    • It spreads when it is eaten and given off as waste by small birds or small mammals. 
    • The autumn olive re-sprouts vigorously after cutting or burning.
    Where is it now invasive?  It has been reported in all states of New England as well as in Wisconsin, Illinois, and Missouri. 

    Is this species in Maine?
     This species is in Maine.
    Where has it been identified?
     Along the east coast and into the mid-west.
    How was this species introduced?
     This plant is introduced to Maine by birds, small animals, and was planted by humans.

    Natural Environment
    • Disturbed areas, roadsides, pastures, and fields with wide ranges of soil.
    • Can live with out a lot of water. It's roots allow it to thrive in poor soil, 
    Climate and Temperature Range
     It's is hardy in a zone 3 climate. Temperature range 10 degrees C at night and 20 degrees C
     during the day when seedlings, will tolerate temperatures down to -40 degrees C.

    Ecological Interactions  Producer
     My species gets nutrition though photosynthesis.
    Consumed By
     Birds, like the starlings, some humans, and some small animals like skunks, raccoons, opossums.

    Ecological  It can over grow and block small plants from growing. It will invade and kill smaller and weaker
     plant life. More detail.
    Human  This fruit is edible and works good as a dried fruit. It has more nutrients/benefits than a tomato,
     but some people say it doesn't taste good because it has a tart taste.
    Economic  The economic impact is maintenance of the plant. The Maine Department of Agriculture is
     managing the economic control, not allowing it to be sold .

    Control  More detail.
    Biological None known.
    Mechanical/Manual A combination of mechanical (weeding by hand), and chemical treatment is the most successful in treating it(putting chemicals on the roots after you have cut the plant off). mechanical would be pulling it out and the chemical would be putting pesticides on it.
    Cultural In Maine the Department of Agriculture does not allow it to be sold in nursey.
