in the off chance of a phenomenon which effectively removes most of the lifeforms in these areas, the resultant landscape is considered to be a "disclimax", where there is a loss of the previous climax community. factors which interrupt succession include: human intervention (plagioclimax), change in relief of land (topoclimax), change in animal species (biotic climax) or change in soil such as an increase in acidity (edaphic climax) . in most cases, should the area be left to regenerate as normal when the limiting factor is removed, the area eventually becomes a "climax community" again (secondary succession).
