Soil responses to human recreational activities in a blackbrush (Coleogyne ramosissima Torr.) shrubland

Soil responses to human trampling, biking, and off-road motor vehicle traffic were quantitatively investigated in a blackbrush (Coleogyne ramosissima Torr.) shrubland in Kyle Canyon of the Spring Mountains in southern Nevada. Soil compaction, bulk density, and temperature increased significantly, while soil moisture, organic matter, and percent pore space (macropore) decreased in disturbed (compacted) areas compared to adjacent undisturbed areas. Among disturbed soils, motor vehicle trails and parking lots had a significantly greater compaction, higher bulk density, and a lower percent pore space compared to human hiking/biking trails. Water infiltration and area of water spread (surface water runoff) were an interactive...
