Detailed explanation-1: -The fire destroyed the vegetation. The fire leaves behind empty but does not destroy the soil. Grasses and other herbaceous plants grow back first. Small bushes and trees started to colonize the public area.

Detailed explanation-2: -Secondary succession starts when a disturbance (such as wind storms, insect outbreaks, logging, avalanches, bulldozers, or fire) leaves the soil intact. Seeds, spores, and roots usually remain as well. Sites that begin with secondary succession reach the next stage more quickly than during primary succession.

Detailed explanation-3: -The natural pattern of recovery after a wildfire is referred to as “ecological succession.” This is the process whereby the land, plants and wildlife move through various ecological stages in order to return to a state of relative stability.

Detailed explanation-4: -Secondary succession begins after a disturbance, like a fire. Crucially, some soil and nutrients remain present-fire, in fact, may help recycle those nutrients.
