The main theories of origin of the European Arctic tundra and subarctic mountain(goltzy)deserts are reviewed, in application to the Kola Peninsula. The theory of «tabula rasa» stated that all plants died during glaciation, and then immigrated fromtheCentral Europe, Siberia, and British Isles. According to another theory, during several Pleistocene glaciations, plants survived in ice-free refugia. Modern bota-ny point of views supports post-glacial migration of species and rather «tabula rasa»theory. The border of the timberline moving up inthe Holocene thermal optimum did not affect the subarctic mountain de-serts, unlike the tundra zone. Based on this, the evolution of the high mountain deserts vegetation probably meant the establishment of groups of species that differ from modern communities of the lower disposed tundra zone. Many types of mountain tundra vegetation, apparently, came from the mountains of North-East Azia; however, many species have been originated from the forest communi-ties. The subarctic mountain deserts have apparently not changed since the retreat of the glacier.

Until 1980, official policy forbade intentional veld- burning within the boundaries of the Etosha National Park. It was only in 1981 that fire was recognised by management and research as playing a fundamental role in the development and maintenance of the cur- rent vegetation communities. An objective approach to intentional veld-burning is presented simulating the incidence of lightning fires, and the subjectivity in choosing areas to burn is reduced. The selection of areas to burn depends on the mean seasonal rainfall in each burning block, the time since it last burnt and the accumulation of herbaceous fuel. Additional factors considered are the moribundness in grasses, the game pressure and the cover of green vegetation derived from satellite data.
