Placement of trees in a pasture - ?

That makes a lot of sense to me, but on our hilltop we get a lot of wind (30 - 40 mph about once a week). The wind comes from the direction of the pasture toward the hilltop, so I'm thinking the leaves might just all blow to the neighbor's unused creekbed and down to the river! I could plant pine trees (looking at Virginia pine because it likes rocky hilltops and clay soil, according to Musser Forests), which would have the added benefit of winter windbreak and vitamin C source for the animals to self-medicate (pine tips are very high in vitamin C). Plus I don't think the needles will blow away like dry tree leaves.

Of course, Australia is a completely different ecosystem than Kentucky/foothills of Appalachia. I think my australia might be similar
Try stone pine, bunya,artemesia ,dont forget californian redwoods oaks honey locust pecans walnuts running bamboo etc

The way my property is set up now, the trees are at the bottom of the hill, where it gets steeper and there are seasonal creeks that carry the water down to the river at the bottom of the hills. My house is on the top of the hill (to take advantage of the magnificent view). I could plant some more trees around the yard (living air conditioners), and also on the tops of the ridges that slope down from the house and driveway. I've never managed a pasture before, tho - is there any reason this would be a bad mistake? The ridges run roughly east-west, the storm winds (high winds) come from the West and blow up the hill toward the house, which is at the top. We own mostly West of the house, and just a little bit to the East.
