Sycamore Maple, Acer pseudoplatanus


Scientific Name: Acer pseudoplatanus.
Common Name(s): Sycamore maple,

INVASIVE to MAINE

Research Summary
: Olivia A.
My observations while doing this research were that some information was hard to find, like the origin and where it is in Maine. Yes, it was difficult for me because my species was a little complex because of how many limited facts there were. There were enough resources, but I thought there could be a little more of them because some of the sites said different things than others.

What surprised me was that the sycamore maple can give humans serious allergic reactions. Some of the most important things I discovered about my species is that it can thrive in many different areas.

Location and Movement
Origin/ Native Range

Introduction
  • In 1870, the sycamore maple was in New York and New Jersey.  
  • Brought to New England and the mid-Atlantic for horticultural purposes where used for only a park or street tree.
Spread of Species
  • Seeds spread when it escaped from cultivation; wind spreads prolific seeds. (Prolific is producing fruit freely.)
  • Were widely planted in North America.
Where is it now invasive?
  • Norway, Australia, New Zealand.
  • Also common in northern Ireland and the Yarra ranges of Australia.
  • United States: CT, DC, DE, IL, KY, MA, MI, NC, NJ, NY, PA, RI
  • Canada: BC, NB, NS, ON. 

Maine
Is this species in Maine?
Yes, the sycamore maple is in Maine.
Where has it been identified?
 Is in all counties but looks to be more concentrated in Washington, Hancock, Waldo, Knox, Lincoln, 
 York, Cumberland, Oxford, and Somerset counties.
How was this species introduced?
 Date of first introduction is unclear.


Habitat
Natural Environment
  • Abandoned fields, early forest, open disturbed area, pasture, roadside, vacant lot, yard or garden area. 
  • Prefers soil types like sand and clay, and the texture of the soil should be about medium, which means the soil texture is not too soft and not to hard, but right in the middle.
Climate and Temperature Range
 The hardiness zone is 4-7. 4a (-30 to -25 F), and  7b ( 5 to 10 F).



Nutrition
Ecological Interactions Producer.
Obtaining food
 The sycamore maple gets its nutrients from photosynthesis.
Consumed By
  • American dagger moth, March moth, hazel leaf roller, and the gray squirrel disturbs the tree.
  • Pollinators are bees.


Impact
Ecological
  • Is capable of producing large amounts of young, giving rise to the dense trees. 
  • Also, this tree absorbs lots of light "hogging" all the light from other trees.
  • Might disturb other maple trees.
  • Makes a good windbreak for exposed and maritime areas.

Human Can give humans serious allergic reactions to its pollen.
Economic
  • Because it may impact native maple trees, sugar maples could be at risk of being displaced and there could be a negative impact on maple syrup industry.
  • Used for fuel, and makes good charcoal.


Control
Biological N/A
Mechanical You can remove the Sycamore maple by yourself if in your yard. 
  • Step 1: Roots can be deep so try to remove as much as possible. 
  • Step 2: For larger seedlings, cut as close to the ground as possible. 
  • Step 3: Drill shallow holes in the trunk as close to the root zone as possible, then fill the holes with glyphostate product.
Cultural
  • Create regulations that stop nurseries from selling this species as an ornamental.
  • Education citizens to its invasive status so they don't plant it in their yards. 
ChemicalHerbicides for stopping large populations.

Interesting Facts
  • When planted in Britan, the sycamore maple can live for 200 years.
  • Is invasive, but can be considered non-native too.
  • The flower of the Sycamore maple is eatable.
