When a campfire is left unattended, and a forest fire breaks out can eventually result in secondary succession.

Explanation:

Secondary succession refers to the succession process in which an area which was previously colonized is disrupted and gets re-colonized.

Secondary succession often is associated with major disturbing events such as fire, flood, epidemic after which a new set of species dominate the region. Abandoned farms, vacant lands can also undergo succession when relatively resistant species of plants can dominate the land following the extinction of the pioneer species.

Forest fire plays a major role in secondary succession by initiating it. Forest fires raze every pre-existing plant to the ground and lay the vacant ground ready for colonization by new species.
