The southern pine beetle is native to North America and can cause extensive damage to evergreen tree species throughout the southern United States.  Damage from southern pine beetle has been found as far north as Maryland, Delaware, and southern New Jersey.  In the fall of 2014 damage to pitch pine from southern pine beetle infestation was detected on Long Island for the first time.  Pitch pine is a dominant species in many stands on Long Island and loss of these trees would dramatically affect the mix of hardwood and pine on Long Island.  Detection traps have been placed in New Hampshire, Rhode Island, Massachusetts, Connecticut, and New York.  These traps have revealed the presence of southern pine beetle in northern New Jersey, southern New York, Connecticut, Massachusetts, and Rhode Island.  Southern pine beetle has not yet been found in New Hampshire.  The evidence reveals that southern pine beetle is moving into areas north of its historic range. It is inferred that is the result of the warming climate.
