Sustainable Restoration of Degraded Landscapes Improves Soil Glomalin Content

Abstract

Abstract The rising use of plantations forwood and cropping systems for food, the agronomic pressures, and resource overexploitation, in addition to climate change constrains, need urgent efforts for restoration of the different vegetal covers. Thus, research in ecosystem restoration is rising worldwide as the perception that global change negatively affects ecosystem services as well as the above and belowground biodiversity. Among microorganisms, mycorrhizae and Rhizobia benefit and contribute to the natural regeneration of plant communities. Consequently, the study of mycorrhizas in natural ecosystems supplement with relevant information the restoration plans. The understanding that most plants are mycotrophic influences the rehabilitation efforts of varied vegetation types. We show here the ecosystem restoration with respect to the benefits of plant symbiosis. As an index of soil stabilization in the different sites glomalin content (Undisturbed= Restored > Disturbed), was the best predictor of restoration success.
