Ecological succession refers to the process of changing in an ecological community's species composition through time. The time frame might span several decades or fewer (for instance, following a wildfire).
The community grows through an increase in complexity from a small number of pioneer plants and animals to a stable or self-sustaining climax community. The effects of established species on their own settings serve as the "engine" of succession and the reason why ecosystems evolve. Living has the effect of changing one's surroundings, sometimes subtly and sometimes blatantly.
