It is not grazing alone that affects biodiversity, but rather the management of grazing that can affect biodiversity.
Poor management–which means turning out livestock to a large area and not moving them for several weeks or months–can decrease biodiversity, causing more desirable species to be pushed out by the less desirable species, and more species that are more suited to heavy grazing (which there are few [much more are forbs or weedy species, not grasses], unlike those that are less suited to heavy grazing) to come in. Poor management invites livestock to selectively graze whatever plants they want and how often they graze a particular spot, which in turn invites overgrazing as well as undergrazing.
Good management–which involves actively managing how long livestock are grazing a particular paddock and how long the plants get rest, what time of year they graze that area, and how many animals are actively grazing at a single point in time–will do the exact opposite, in fact increase biodiversity. When cattle can graze plants that have set seed, especially if these are desirable species, they can move these seeds from one location to another with their manure. Undesirable species would still be present, but they become less of a nuisance and much less noticeable than if livestock were poorly managed.
When a whole herd of cattle or sheep can be moved around on a large piece of land every one or three days, allowing at least 30 or 40 days of rest to each paddock on that piece of land, the soil and the plants on it improves. When livestock are no longer allowed to damage riparian and wetland areas and watered in a location that takes livestock away from these sensitive areas, the biodiversity also improves and increases. But, these areas should still be grazed, just not as often as the upland, non-wetland areas.
No, pastures and rangelands are not always damaged by grazing animals. When managed properly, grazing can promote healthy plant growth, improve soil fertility, and enhance biodiversity. However, overgrazing or poorly managed grazing can lead to soil degradation, plant species loss, and erosion. Sustainable grazing practices are essential to maintaining the health of these ecosystems.
They maintain biodiversity.
Humans need biodiversity ,as biodiversity is related to the ecosystem if there is a shift in biodiversity then there will also be a shift in the ecosystem which will in turn affect human life

Neutral mutations do not have a significant impact on biodiversity because they do not affect an organism's ability to survive and reproduce. Biodiversity is mainly influenced by mutations that provide a fitness advantage or disadvantage, leading to changes in the frequency of different traits within a population. Neutral mutations simply accumulate over time without impacting biodiversity directly.
Yes, grazing can affect soil erosion. Overgrazing can remove vegetation cover, making the soil more susceptible to erosion from wind and water. Proper grazing management, such as rotational grazing, can help maintain vegetation cover and reduce soil erosion.

Provide food for grazing animals and hold the soil in place
Grazing can compact soil, reducing pore space and leading to increased soil density. This compaction can result in diminished soil aeration and water infiltration, which can affect root growth and overall soil health.
Cows help bees by promoting a healthy ecosystem through their grazing habits. Their grazing can stimulate the growth of diverse flowering plants, providing bees with a rich source of nectar and pollen. Additionally, cow manure enriches the soil, supporting plant health and biodiversity, which further benefits bee populations. This symbiotic relationship enhances agricultural productivity and biodiversity overall.
