Fire suppression in a fire-adapted ecosystem can lead to
A.fuel buildup and catastrophic later fires
B.permanently higher biodiversity
C.no ecological consequences
D.increased nutrient loss
Explanation
Core Concept
In fire-adapted ecosystems, suppressing frequent low- or moderate-intensity fires can allow combustible material to accumulate and can alter vegetation structure. Under some conditions that increases the risk of severe later fires or woody encroachment. The outcome depends on ecosystem and fire regime, so avoid saying generically that 'fire-intolerant species invade.'
Correct Answer
Afuel buildup and catastrophic later fires
