These intense but brief stays completely change the animals’ interaction with the grass and the soil. They eat down just about everything in the paddock, and then they move on, giving the grasses a chance to recover. Native grasses evolved to thrive under precisely such grazing patterns; indeed, they depend on them for their reproductive success. Not only do ruminants spread and fertilize seed with their manure, but their hoofprints create shady little pockets of exposed soil where water collects—ideal conditions for germinating a grass seed.
