A review of the effects of off-road vehicles on birds and other vertebrates
1980
Berry, K.H.
A review of the literature on the effects of off-road vehicles (ORVs) on birds revealed five papers, only one of which covered the subject in depth. There are several additional papers on impacts of ORVs on fishes, Amphibians, reptiles and mammals, most of which deal with species of the arid Southwest. Almost without exception, analyses of the data revealed that ORV use has significant negative impacts and can reduce numbers, diversity,and biomass of vertebrates. The degree of impact depends upon amount and intensity of ORV use, habitat type, and sensitivity of the species. The literature on effects of ORVs on soils and vegetation--major wildlife habitat components--and on related topics such as erodibility of soils, rates of erosion, and revegetation, is much more extensive. Information from such studies infer the kinds of impacts that can occur to birds and other vertebrates.
