Ain't that the truth. But (as I'm sure James knows) it would be less interesting to the eye and - apologies to my grandfather - as flat as Kansas. Trees and terrain also produce significant variation in the landscape - and shelter. My cows love making little forts in the overgrown hazelnuts inside some paddocks... as a first time cow-dad I was a little alarmed by their disappearing act but then my calls would induce some rustling and a cow would pop a head out of the bushes.
I'm about to make a cross-species comparison - I'm not sure it works. Our
local favorite of a dog park seems superior is part because of the terrain. Its a large park without a
fence, flowing into soccer fields, a play ground, other turf. But its NOT flat. Its heavily forested and has wide, deep valleys. The dogs at this park always seem more chill than at some other parks. I attribute this partly to the terrain: there is no fence, so dogs can run away if they must (fight or flight... they can fly so they are less likely to fight). The valleys and trees make spaces more intimate, more bounded and reduce that sense of "being seen", while also reducing the amount of perimeter that has to be scanned for possible threats - yes, even in a dog park. We generally think of prey animals being safest in the middle of a cleared field with sight lines that stretch for miles - but my cows seem to feel differently, preferring to hide under the low branches of a douglas fir even when shade isn't an issue. In some sense I think the visually distinct pastures also add some texture to their life - its like the difference between living in a giant open warehouse and a house in which you can go from room to room.
So to conclude ... terrain does make the decisions and the application of fencing difficult, but at this point I don't think I'd trade my rorshach blot pastures for a bare rectangle of grass!
