The compaction and waterlogging of soil caused by the tramping of grazing animals. a process called Pugging. The animal footprints or pugs, collect standing water, the soil is bared and exposed to damage from raindrop impacts. Highly compressible soils such as Andosols are particularly prone to this damage as can be seen in the picture from the island of San Miguel, Azores (Figure P71).
