Secondary succession

• • Many human activities that disturb climax communities such as tree felling, ploughing and burning, recreate conditions that were suitable for the species that colonised the area earlier in the sequence of ecological succession
• • These species recognise the area, if the habitat is left alone, succession will continue to change and will eventually recreate the climax community. This is secondary
• • This takes place more rapidly than primary succession because the soil does not have to develop and many of the seeds will already be present so there are fewer delays caused by the time taken for species to colonise
