Botany: pine trees: red vs white: an observation about ecology?

Self-tutoring about ecology and observation: the tutor makes one.

Where I lived in the Annapolis Valley, we had two common pine trees: red and white. Both were common, especially in sandy places.

Wondering what ecology might favour one versus the other, I’ve come to realize that the white seemed often to grow alone, but the red was usually found in groups. I’ve come to wonder, therefore, if white is more tolerant to wind.
