As for Troutbert’s comment about the fences....And so you would think, but fences have to be maintained and when the creeks get high they become a tangled up mess with debris. There are landowners who don’t want the extra work. In addition, they sometimes say they need to mow around the posts and under the fence. I don’t know if high grass, etc breaks up the electrical field or what. They say that the cattle push on the fences. Any farmers out there to explain this?
On the pasture side of the fence, the cattle will keep the vegetation down.
But on the buffer side of the fence, yes, the farmer must keep the vegetation down. People with wide buffers often run a brush hog along that side once a year or so. So the first strip of the buffer is thick grass, which actually is good at intercepting flow, spreading out the flow, holding the soil etc. Then have trees and shrubs between that grass strip and the stream. In some cases, a grass strip on the outside of the buffer is done by design, for that reason.
Farmers also commonly use trimmers to maintain along the fence. And Amish do use gas-powered trimmers.
The reasons for keeping the vegetation trimmed along the fence are that the vegetation can short out electrical fences. And all fences require repair and maintenance over time, so you don't want brush, vines, trees etc. all over the fence, because it would make fence repair a nightmare.
As I said though, all farmers with grazing animals have fences, and the maintenance that goes with that. That goes with the territory of having grazing animals. That goes way back before riparian buffers existed.
And having a good fence along the stream can help with rotational grazing systems, which are becoming very popular.
