Low-budget methods of aerial photography in lichenological studies

Budgetary small-sized unmanned flying devices allow charting trial areas with small expenses. They overlap range of heights from few meters to several hundred meters. Such devices are useful to a considerable degree for recording the dynamics of fruticose and foliose epigeic lichens. Cladonia stellaris, C. arbuscula, Flavocetraria cucullata, Peltigera spp., Stereocaulon spp. are the most suitable as indicator species for such studies.
