Abstract

The Apolobamba Integrated Management National Area is located in the Northwest of La Paz (Bolivia). This grassland ecosystem, with a high biodiversity, is a natural habitat of camelid populations. The goals of this study were to quantify total SOC contents as well as its quality by applying 13C CP/MAS-Nuclear magnetic resonance spectroscopy, and determine the degree in soil exhaustion in selected zones on the basis of the degradation of SOM, related to vicuna and alpaca populations. Although, results showed that some studied zones could be excellent carbon reservoirs the AA. suggest that these zones should be specifically protected from camelid overexploitation to avoid the soil exhaustion and preserve high grassland ecosystems and its biodiversity in the Apolobamba area
