How can snowmobiles impact vegetation?

Snowmobiles can significantly impact vegetation primarily through their physical movement and the disturbances they cause in their environment. When snowmobiles traverse over snow-covered areas, they can compress the snow and expose the soil and underlying vegetation. This exposure can lead to the destruction of plant life, especially in fragile ecosystems where plants may not be well-adapted to recover from such disturbances.

In particular, areas with sensitive vegetation can suffer from damage when snowmobiles break through the protective layer of snow, leading to soil disruption and potential loss of plant roots. The destruction can hinder the growth and reproduction of plants, especially in ecosystems where vegetation is sparse or has a slow growth rate. Therefore, the correct answer highlights the negative impact snowmobiles can have on vegetation by causing both exposure and destruction, which can lead to long-term ecological effects.
