[1] F. watkinsiana grows on another tree, using it as physical support, while also stealing sunlight, nutrients, space, etc.

F. watkinsiana produces a large amount of fruit, which feeds a variety of mammals.

One mechanism may be lacking deep branches and hollows, and having smooth bark so there's no place for the seeds to become lodged and grow.
