AB  - There is increasing awareness of the damage caused to valuable and often unique 
      sensitive habitats by people pressure as degradation causes a loss of plant 
      species, disturbance to wildlife, on-site and off-site impacts of soil movement 
      and loss, and visual destruction of pristine environments. This research 
      developed a new perspective on the problem of recreational induced environmental 
      degradation by assessing the physical aspects of soil erosion using the fallout 
      radionuclide caesium-137 ((137)Cs). Temporal sampling problems have not 
      successfully been overcome by traditional research methods monitoring footpath 
      erosion and, to date, the (137)Cs technique has not been used to estimate 
      longer-term soil erosion in regard to sensitive recreational habitats. The 
      research was based on-sites within Dartmoor National Park (DNP) and the South 
      West Coast Path (SWCP) in south-west England. (137)Cs inventories were reduced on 
      the paths relative to the reference inventory (control), indicating loss of soil 
      from the path areas. The Profile Distribution Model estimated longer-term erosion 
      rates (ca. 40 years) based on the (137)Cs data and showed that the combined mean 
      soil loss for all the sites on 'paths' was 1.41 kg m(-2) yr(-1) whereas the 
      combined 'off path' soil loss was 0.79 kg m(-2) yr(-1), where natural 
      (non-recreational) soil redistribution processes occur. Recreational pressure was 
      shown to increase erosion in the long-term, as greater soil erosion occurred on 
      the paths, especially where there was higher visitor pressure.
