Mapping, Lichens, Mosses, Antarctic flower plants The objective of this work was the to present a study about plant communities on icefree areas of Hennequin Point, eastern coast of Admiralty Bay, King George Island, Antarctica. The study of started with the classification and description of the plant communities based primarily at phytosociological and biodiversity data. The area was mapped by using an Astech Promark II® DGPS, which is able to obtain a submetric precision after post-processing with the Astech Solutions® software. The five plant communities were described as following: 1. Lichens and moss cushions communities, 2. Moss carpets and crustose lichens communities, 3. Emergent communities, 4. Deschampsia antarctica and ornithocoprophilous lichens communities and Deschampsia Antarctica, mosses and lichens communities. The plant communities were presented on a map in a 1:5000 scale containing the community characterization and distribution.
