Question

Over a 1000 years, a lake becomes a maple forest. is this an example of primary or secondary succession?

Answer 1

As a shallow lake fills in with decomposing plant material, it turns into a marshy area, then a field of soggy soil, then dry land with shrubs, then trees, then a forest which will remain there until a climate change or forest fire, earthquake or some such occurs. I think this initial change from a lake to a forest is primary, but the regrowth after an earthquake or fire would be secondary.

Answer 2

It can be primary change or succession if maples were around the lake..

In secondary succession the scenario changes too rapidly like the reverse. A forest changed into the lake because of volcanic eruptions or the earthquake.

Still I feel a lake change into a maple forest is too fast. THis does give the just enough time to maples to complete few generatrions. If there was no maples by the side of lake at the start then this change of lake into maple forest would have taken about 2-10 thousand years and that would have been definitely primary.

But if  it has occured in just 1000 years, then it is 50:50.
