Well for one thing natural forests are pretty mono-species, most of North Eastern North America was forested mostly with White Pine when the first Europeans arrived. Even in forests intense species competition exists with the more successful driving out the less successful. However there is a thousands of years long cycle of fire, grass, deciduous, then evergreen that the normal way of unmanaged forests. The evergreen forest like in North America is called a climax forest* because it is the last stage of the cycle. Note the interesting point that massive forest fires are a natural part of the cycle.
