AB A well-managed grazing system improves the productivity and health, and it is importantto promote sustainability. We analyzed the impact of grazing on the Sierra de Zapalinamé protectedarea in north Mexico. Our hypothesis was that grazing modifies species composition, richness, andnutrients after grazing exclusion for five years. In this area, eight plots were excluded from grazing,and species richness, evenness, and plant functional types for five years were monitored. Thismonitoring was also carried out on eight control plots adjacent to the excluded plots. Soil sampleswere collected from each plot in the fifth year of exclusion for nutrient content analysis. Grazingdiscriminated plant species composition after five years between excluded and control plots, butnot species richness and evenness. In addition, exclusion increased grass cover and decreased forbcover. Indicator species for excluded and control sites were identified. It was concluded that part ofthe pastures can be excluded from grazing as a way to analyze changes in this protected area andpromote greater plant diversity.
