why is fire considered a common management practice?
suppresses invasive species such as shrubs and trees
teaches grazing animals to stay away from specific areas
fire burns and removes topsoil so more fertile soil will be available
fire is not a common management practice and should be avoided

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: Fire is used in grassland management to suppress invasive woody species (shrubs, trees) that can outcompete grasses. This is a common practice.
• Option 2: Fire does not teach grazing animals to avoid areas; grazing management uses other methods.
• Option 3: Fire does not remove topsoil; it can actually enrich soil with nutrients, but not by removing topsoil.
• Option 4: Fire is a common management practice (e.g., prescribed burns) for grasslands, so this is incorrect.

Answer:

A. Suppresses invasive species such as shrubs and trees
