Answer :
1. The population growth of feral goats in Australia had a negative impact on the environment. As goats are known to be voracious grazers, their presence led to overgrazing of native herbs, grasses, trees, and shrubs. This excessive grazing caused degradation of vegetation, soil erosion, loss of biodiversity, and disruption of ecosystems. It resulted in the degradation of natural habitats for other native wildlife species, leading to a decline in biodiversity.
2. Goats are considered great animals to have on a farm for several reasons. They are known for their versatility and adaptability to various climates and terrains. Goats are efficient at clearing unwanted vegetation, such as weeds and brush, making them useful for land management and vegetation control. They are also valuable for their meat, milk, and fiber production, providing economic benefits to farmers. Additionally, goats require less space compared to some other livestock, making them suitable for small-scale farming operations.
3. One of the effects of goats grazing on native herbs, grasses, trees, and shrubs is the potential alteration of the plant composition and structure in the ecosystem. As goats consume vegetation, they can impact the growth and reproduction of native plants. This can lead to changes in the plant community composition, reducing the diversity of plant species present in the area. Furthermore, overgrazing by goats can prevent the regeneration of native vegetation, affecting the overall health and resilience of the ecosystem.
