Would you be able to elaborate some on this? I'm curious to know how exactly they repair land.
Are you familiar with the benefits grazing and browsing hoofed animals provide landscapes, if properly managed (rotational grazing)? It's the same general principle for all hoofstock--cattle, sheep, goats, etc. Bison included.
The long and short of it is, when landscapes are subject to periodic disturbances, like pressure from big grazers, they respond with a massive rebound of fertility and diversity. Grazing stimulates the growth of grasses and many other plants. Manure and
urine deposit lots of nitrogen into the soil, supporting faster and more varied plant germination and growth. There are even plenty of species' seeds that don't germinate in the absence of crush pressure, as from a large animal stepping on/compacting the soil they're resting in.
Basically, hoofstock--especially large hoofstock like bison and cattle--are an integral part of prairie biomes, and our domestic pastures attempt to mimic prairies on smaller scales. As with any other
permaculture system, when you bring animals into the picture you create greater and more
sustainable synergies that reduce the need for inputs and increase production. But the pressure from large grazers applies to musk oxen and bison equally. Either species will be great for your land, if you rotate them with care.
This article focuses on bison's benefits for prairie/pasture landscapes specifically.
