The forest ecosystem is called, "Laurentian-Acadian Pine-Hemlock-Hardwood Forest." It is primarily found in the New England states. However, to be noted, it also finds a home among the Northern Hardwood Forest at lower elevations.
Every forest ecosystem is unique, but, it does not mean it is neatly tucked into state boundaries. If hiking or walking through a dense New York State forest and run across Red Oak or Hemlock in the canopy, they aren't invasive so much as their genetics are PLASTIC ENOUGH to allow the trees to grow slightly more south and west.
