How does summer grazing by sheep and cows affect Alpine meadows?

Summer grazing by sheep and cattle in Alpine meadows is a form of agricultural exploitation that is generally light or seasonal due to the low productivity of mountain environments.1

While often practiced at low levels, grazing can become highly destructive when it occurs at moderate intensity. Because Alpine vegetation exists in an environmentally stressful habitat, it lacks the resilience to easily recover from the disturbances caused by livestock. Consequently, overgrazing or intensive use can lead to permanent damage to these fragile plant communities.1

Beyond grazing, other human activities such as skiing and recreation, as well as the accumulation of atmospheric pollutants in snowmelt, also pose significant threats to the stability of these mountain ecosystems.1
