Paul, I have considered this. It is my impression that the hawthorns are encroaching into the fields covered by the grass. I think that many of the smaller hawthorns are younger than the age of the grass fields. Shade intolerance could be a part of the effect I am seeing, but under other scattered trees of other species that occur within or surround the grassy areas the grass is growing underneath them without any of these visible differences. The shade from these trees do not seem to be limiting the growth of the grass. The grass does not seem to be affected noticeably by the shade of these trees and the hawthorns are not any more foliage dense than these other species. It is just under the hawthorns that I see this effect. That is why I am think alleopathy rather than shade effects.

I've seen similar effects with hawthorns over other grasses.
