Comment about trees growing on a hill:
Seeds will sprout and grow straight up regardless of the slope of the hill.
UNLESS: If the land is slowly creeping down the hill the base of the tree will tend to point down hill to some degee depending on age and rate of soil movement. The upper portion will tend to rotate with growth trying to grow straight up. (as in the lower tree trunk on the slope.) Over time this is very noticeable if there are many trees on a hill with constant creep. |
