not only scars the land, but also pollutes water and 

 impairs fisheries and aquatic wildlife. Desert lands 

 and alpine tundra are especially fragile environments 

 where resource damage can require decades of natu- 

 ral repair. 



Off-road vehicle use has intensified the recreational 

 pressures on public land and has resulted in addi- 

 tional problems such as air, noise, and esthetic pollu- 

 tion. Noise pollution, in particular, may disrupt wild- 

 life. It can also reduce the quality of the esthetic 

 environment, detracting from the enjoyment of some 

 recreational users who desire a quieter, more peaceful 

 experience. 



Crowding can be a significant social problem at 

 those times when users experience higher densities of 

 use than they desire. Often, it is not only the number 

 of other recreationists encountered that decreases the 

 users' satisfaction with their experiences, but also the 

 type of use. Conflicts can arise between hikers and 

 horseback riders and between these users and vehicle 

 drivers. Other social problems, such as Uttering, van- 

 dalism, and even theft, have resulted from greater 

 participation in dispersed land activities. And prob- 

 lems of public health and sanitation, including 

 human injury and improper waste disposal, have also 

 increased.
