Combined evidences obtained from the palynological, geological and archaeologi cal studies provide the basis for the interpretation of plant ecology of shore and further the vegetational history of the marine area. In the meantime, plant ecology itself is concerned not only with plant communities but also the interaction among the plants involved, and their environmental factors.
