What is plant succession?

Plant succession?

• their mechanism and the processes that bring about succession

• Answer:

  Many plant communities are not self-sustaining. A field in the temperate deciduous forest biome will remain a field only as long as it is grazed by animals or mowed regularly. If these factors are eliminated, the balance tips in favor of other species. The newcomers many, in turn, by their own growth sow the seeds of their own destruction. For example, the gray birch grows well only in sunny locations. The shade it casts prevents its own seedlings from growing beneath it, but permits white pine seedlings to become established. When mature, white pines then cast so deep a shade that the gray birch is no longer able to survive there.
