Directing Ecological SuccessionSuccession, the tendency of plant communities to change through time, presents a challenge to those who must satisfy goals established for the use and preservation of natural resources. The practical application of what is known about successional changes has not advanced quickly; subsequently plant community management is often carried out without recourse to the latest scientific data. |
