Transition
Explanation:
Secondary succession occurs when the existing vegetation is removed by some disturbances and soil is already present in the region to support the growth of new species. During succession, the early species are being replaced by later successional species.
In the given example, the forest has patches of early species and later species. This means that the forest is in the transition period of succession where early species were not completely replaced by the new species. Once the early species will be removed and the climax community develops, the forest has reached the final stage of succession.
