After a forest fire, when above ground plant parts are killed ferns are often one first plants to appear ? Why ?

Explanation

1. On the Forest floor, ferm stems live safely tucked below the ground.
2. They survive moderate fires even if all fronds are burnt away.
3. Once rains come and light is availble, and when nutrients get released after the fire, new fronds are produced easily.
4. Thus ferns are often the first plants to grow after a fire.
