Anthropogenic Degradation of the Southern California Desert Ecosystem and Prospects for Natural Recovery and Restoration.

摘要: / Large areas of the southern California desert ecosystem have been negatively affected by off-highway vehicle use, overgrazing domestic livestock, agriculture, urbanization, construction roads and utility corridors, air pollution, military training exercises, other activities. Secondary contributions to degradation include proliferation exotic plant species a higher frequency anthropogenic fire. Effects these impacts alteration or destruction macro- micro-vegetation elements, establishment annual communities dominated species, soil stabilizers, compaction, increased erosion. Published estimates recovery time are based on return predisturbance levels biomass, cover, density, community structure, characteristics. Natural rates depend nature severity impact but generally very slow. Recovery cover biomass may take 50-300 years, while complete require over 3000 years. Restorative intervention can be used enhance success rate recovery, costs high probability for long-term is low moderate. Given sensitivity habitats disturbance slow natural best management option limit extent intensity as much possible.KEY WORDS: Mojave Desert; Colorado California; Human impacts; Recovery; Restorationhttp://link.springer-ny.com/link/service/journals/00267/bibs/24n3p309.html
