biotic disturbance due to human traffic - lichen, bryophytes, moss, algae etc. would be happening on the ground and also on the rock. Effects on the ground include changes in moisture retention, biomass and soil nutrients. on rock there are microscopic organisms that live within moss and also feed on algae etc. So effectively influencing a whole microhabitat. human and vehicular traffic also compact the ground, which influences soil communities. human foot traffic and cars spread weeds and also plant diseases via seeds etc stuck to shoes, tyres etc. also consider increased air pollution due to vehicles.
