Rhizobia Isolates, Land Restoration, Cottonwood Oasis


Environmental Microbiology and Microbial Ecology


This research is part of a larger project to restore a section of the Cottonwood Wash in Joshua Tree National Park. Previous research has found that the best plants used to restore the disturbed desert sites are woody legumes. One of the reasons for choosing legumes is their symbiotic relationship with the soil microbes, rhizobia and mycorrhizae. In these symbioses the bacteria rhizobia fix nitrogen and the fungus mycorrhiza increases the uptake of needed chemicals. This research looked at the natural diversity of these two microorganisms in the disturbed site, comparing it to a reference site.
