Ecological succession is the tendency of an ecosystem to get more complex over time, until it reaches a stable balance, or climax community. A long term study was performed by a group of scientists that evaluated the factors that effected the rate of ecological succession. The start of their studies was noted as year zero. Figure 1 shows the soil depth and vegetation changes as they occurred over time. |
