challenge. Conference Proceedings,

Research concerning off-road vehicle 
impacts on wildlife is reviewed to il- 
lustrate the level of impacts and to 
provide guidance for more effective 
protection of wildlife in off-road 
vehicle areas. Effects on wildlife 
include direct mortality, damage to 
vegetation, disruption of soil, and 
noise harassment. Research and man- 
agement recommendations are suggested.

Impacts of off-road vehicles on creo- 
sote shrub habitat and associated 
wildlife were studied in California. 
Diversity, density, and biomass of 
birds, reptiles, and small mammals 
were inversely related to the level of 
vehicle use. Widespread negative im- 
pacts of off-road vehicle use on wild- 
life must be recognized to manage re- 
sources in areas of vehicle use.
