grasslands: conservation & management
5 of 5
why is fire considered a common management practice?
○ fire is not a common management practice and should be avoided
○ fire burns and removes topsoil so more fertile soil will be available
○ suppresses invasive species such as shrubs and trees
○ teaches grazing animals to stay away from specific areas

Explanation:

To determine the correct answer, we analyze each option:

• The first option claims fire is not a common management practice, which is incorrect as controlled burns are used in grassland management.
• The second option says fire removes topsoil for more fertile soil, but fire typically doesn't remove topsoil to make it more fertile (it can actually help recycle nutrients, but the description here is inaccurate).
• The third option states fire suppresses invasive species like shrubs and trees. In grassland conservation, controlled burns are used to prevent woody (invasive in grasslands) species from taking over, maintaining the grassland ecosystem. This is a correct reason for using fire as a management practice.
• The fourth option says fire teaches grazing animals to stay away, which is not a primary reason for using fire in grassland management.

Answer:

C. Suppresses invasive species such as shrubs and trees (assuming the third option is labeled C; if the original options had different labels, adjust accordingly. Based on the order, if the options are A, B, C, D: C. Suppresses invasive species such as shrubs and trees)
