Easy Math

Callery pear (Pyrus calleryana) is an exotic and known to be invasive tree. Despite this common knowledge, it is planting prolifically in our landscape by city planners, parks and landscape architects.  Walk down any street right now, and you’ll see trees covered in white blossoms – callery pear.  Yes, beautiful, but ecologically problematic.  Here, it was planted along Rt. 440 in Staten Island.

What happens to invasives that are inserted into the landscape?  They leave their place of origin and invade new territory.  Voila! Callery pear now in Conference House Park.  That was easy math.
