Question 72 • (AG Q2) Environmental Science: 26-27 (EMulac)

What is a likely consequence of preventing prescribed burns to forest ecosystems?

Answer
A
Natural wildfires will burn longer and hotter when they occur because there is more underbrush and fuel available.
B
Forest ecosystems will remain healthier overall, due to retention of habitats.
C
Home owners will be better protected against damage from natural wildfires.
D
Natural wildfires will occur less frequently.

Explanation

Prescribed burns remove accumulated underbrush and other fuels under controlled conditions. If those burns are prevented, more fuel can build up, so a natural wildfire may burn hotter and for longer once it starts. This makes choice A, “Natural wildfires will burn longer and hotter,” the likely consequence; preventing prescribed burns does not make wildfires occur less often.
