Wild animals live outside all year round. Same is true for cattle and horses which are being rewilded or de-domesticated. Graslands, herbaceous fields and thickets have evolved to cope with this constant grazing pressure. The amount of animals which can survive within an certain area is determined by the food availability in the hardiest season; winter in central and northern Europe or the dry season in some southern parts of Europe. Within other areas grazers migrate between seasonal pastures. During the vegetation growth season, large herbivores aren’t capable to consume al vegetation. Only the tastiest plants are being eaten, leaving all kinds of flowers and herbs to flourish. This low grazing pressure supports hundreds of thousands of insects, which in their turn are the main food source for many birds, reptiles and amphibians. When hard times return the leftovers of these many plants are again consumed, once more tastier plants stopped growing or disappeared.
This method of grazing is fundamentally different of modern day livestock farming, Within the latter animals our only outside when plants grow well, animals are kept in very high numbers and as a result many plants don’t flower, give nectar or seeds. During winter animals are kept inside in large stables, fed hay, mails or artificial feeding. Many studies showed us that year round grazing under (low) natural animal densities.
