Grazing pressure
Pasture pressure describes the pollution of areas, especially grassland populations, by animal populations.
term
- The term is most commonly used in agriculture . There it is a measure of the intensity of grazing and can be determined by the ratio of the amount of fodder that the grazing area provides to the feed requirements of the livestock grazing on it. In areas that have been grazed for a long time, grazing pressure increases the biodiversity of the pasture.
- In other areas, grazing pressure is associated with game (grazing pressure) or assigned to other herbivorous wild animals.
- Grazing pressures can be positive and negative for the ecosystem. According to studies in pastoral animal husbandry, regular grazing, cattle treading and dung are important aspects of the dynamics of natural open landscapes , because they promote the growth and resistance of plants.
- In a broad interpretation of the term, grazing pressure can also be determined for carnivores , since the grazing pressure does not always only refer to the plants that have been eaten, but also partially to the destruction of the soil by step loads and the like.
