There were a lot of oak leaves on the ground (not in the same area as the pines).
There were some short trees with brown leaves on them. I didn't know what they were, but my mother said the other trees besides oaks that keep brown leaves in the winter are beeches.
There were some smaller hemlocks amidst the tall pines.
Then I went to my dad's house in New Hampshire, and he had tall pines too.
As in Connecticut, along with the pines were the short trees with brown leaves -- presumed to be beeches.
