Vegetation mapping of moss-dominated areas of northern part of James Ross Island (Antarctica) and a suggestion of protective measures
James Ross Island is a large (2500 km) island situated in the north-western part of the Weddell Sea, close to the northern tip of the Antarctic Peninsula. The island is rich in vegetation oases, i.e. areas covered by autotrophic organisms comprising a great variety of terrestrial algae, cyanobacteri...

The island is rich in vegetation oases, i.e. areas covered by autotrophic organisms comprising a great variety of terrestrial algae, cyanobacteria, lichens and mosses.

Sanionia uncinata was found at the only one of the investigated areas and might be considered as rare species for James Ross Island.

Potential of the data for geographical information systems (GIS), further application of unmanned aerial vehicle (UAV) in vegetation mapping, and spectral reflectance parameters measurements of Antarctic moss-dominated areas are discussed. For particular areas, protective measures are suggested to minimize human disturbance of the sites and provide a platform for a long-term study of biodiversity.
