Known as gibbers, hammadas, regs, or sai in various arid regions around the world, desert pavements are especially prevalent on alluvial fans, bajadas, and terraces composed of sediments derived from metamorphic and volcanic rocks.

An important management consideration for desert areas is the amount of time required for disturbed areas to recover naturally, because artificial reclamation techniques are very expensive and prone to failure when applied to large arid areas (Chapters 15 through 17).

The Impact of Vehicles on Desert Soil Stabilizerst, the sparsity of shrubs creates soil-moisture conditions favorable to microflora (Friedmann and Galun, 1974). Extensive areas of soil not protected by vegetation are covered by rock pavements, commonly of great antiquity. Even here a floral niche is found by diaphanous algae. Even bare soil is protected by silt-clay (mechanical) or salt crusts.

Effects of Off-Road Vehicle Noise on Desert Vertebratessing through an area and the observation that many of the . had bloody ears following the race. Following this, Bondello (1976) showed that excessive off-road motorcycle sounds (115 dB A) could damage the acoustical sensitivity of desert iguanas (.).

Soil and Soil Formation in Arid Regions arid regions continuing as a result of land misuse, the need for rational management of soils is paramount. Off-road vehicle (ORV) use is one of the serious management problems in the arid regions, and management of ORV use to minimize the disturbance to soils requires knowledge of what kinds of soils occur in arid lands and how they form.

Compaction of Desert Soils by Off-Road Vehicles contributing factor to accelerated soil erosion (Snyder et al., 1976; see Chapter 5) and a cause of decreased plant growth (see Chapters 7 and 13) in deserts. Hence, a quantitative prediction of soil compaction is of fundamental importance in the formulation of management plans designed to minimize adverse impacts of ORVs on soils.
