Question

scenario 2: a large herd of cattle has been grazing on a section of grassland for many years. because the animals graze the same area continuously, some plant species have been eaten down to the roots, while others are unable to regrow. this overgrazing has led to soil compaction, increased erosion, and the spread of invasive plant species that thrive in disturbed soil. as a result, the grasslands biodiversity is declining, and the land is losing its ability to support healthy grass for the herd to forage. local farmers and ecologists are looking for a new livestock strategy that can protect the soil, promote plant regrowth, and maintain a sustainable source of food for livestock.

1. summarize the problem affecting this grassland in one sentence.
2. based on the lesson 4.3 notes, what sustainable farming practice might be helpful for this grassland?

explain your answer to receive credit.

Explanation:

Overgrazing causes soil compaction, erosion, biodiversity decline, and loss of soil's ability to support healthy grass. Sustainable farming practices need to address these issues.

Answer:

1. Overgrazing has led to soil compaction, increased erosion, declining biodiversity, and loss of soil's ability to support healthy grass in the grassland.
2. Rotational grazing (where cattle are moved to different areas of the grassland at intervals) could be a helpful sustainable farming practice. It allows grass in one area to recover while cattle graze in another, reducing over - utilization of a single area, promoting plant regrowth, and maintaining soil health.
