A pasture grazed by cattle alone is a good pasture.
A pasture grazed by cattle and sheep, together, is something else entirely.
The cattle take the long grass, the coarse stems, the rougher patches. The sheep follow behind and clean up what the cattle ignored: the shorter regrowth, the wildflowers, the species the cattle wouldn't touch. The pasture gets grazed at two heights, by two different mouths, on two different patterns. Twice the use. Twice the work. None of the waste.
Add a goat and the bramble line goes. Add a pig on the woodland edge and the parasite cycles break. Add a few geese and the weeds you didn't even know you had quietly disappear.
The result is consistently the highest-biodiversity, highest-productivity, lowest-input agricultural system on earth. Higher protein per acre than arable. More carbon in the soil. More birds. More wildflowers. Less disease. Less input. Each species breaks the parasite cycle of the others. Each one prefers the plants the others avoid. The system tunes itself.
This is not innovative. It is what almost every functional agricultural society on earth has done forever. Roman estates. Medieval manors. Mongolian camps. Welsh hill farms.
The single-species, single-field, single-product model that replaced it is about a hundred years old and is running out of steam on every metric you can measure.
The fix is older than the problem. It is a Welsh farm with cattle on the lower pasture, sheep on the upper, a goat on the bramble line, and a couple of geese in the orchard.
The farmer would explain it in four minutes if you asked.
The policy paper has not asked.
