What are the issues found in Arches National Park, SE Utah, USA?

• ORVs damage the fragile ecosystem which leads to soil erosion, steam pollution and a loss of wildlife
o ORV trails have grown by 200% in the last 5 years - Utah now has 160,000km of dirt roads
• River crossings increased and the stream bed has been damaged + a loss in fish species
• Tourists can damage natural stone arches
• Increasing accessibility for tourists can damage cryptobiotic crust
o Damage = can prevent further growth of plants
o Crust prevents erosion and holds sand/soil particles in place so they don’t blow away

What are the problems facing Southern Utah?

• Damage to the fragile ecosystem.
o loss of wildlife
o soil erosion
o stream pollution
• Streams, creaks and springs make up less than 1% of Utah’s wilderness area, yet they support over 80% of all wildlife species in the region
• Stream beds damaged: loss of sensitive fish species, and sandy river banks have become deeply eroded
• Soils then become displaced and unable to bind together, become susceptible to soil erosion and to being bakes by the sun
• Noise and dust pollution
• Because of the popularity more areas are being opened for recreation
