Fig. 19. Winter use by reindeer of this windswept low ridge has 
resulted in severe shattering and wind erosion of the lichens. Willows, 
although heavily browsed, show good recovery. (Transect No. 9) 8/3/57. 

Fig. 20. Dryas, sedges and lichens predominate on the higher vegetated 
ridge tops (Station No. 3). The thinner lichen layer is rapidly lost 
through trampling and scattering by wind under heavy winter use by 
reindeer. 8/5/57.
