Answer:
The pioneer stage of secondary succession is taking place in the forest.
Explanation:
Secondary succession occurs when an area that had been destroyed due to factors like fire, flood, etc starts to get colonized by species again.
In the starting stage i.e pioneer stage, plant species start growing on this land. With the passage of time, we enter the intermediate stage, where shrubs start to grow
.
Gradually, we come to the complex stage, where mature trees start to colonize the forest and eventually provides a habitat for other animals.
