Abstract
The degradation of Andean dry puna grasslands is part of the deterioration of terrestrial ecosystems. As a response, exclusionary grazing practices have been applied. However, knowledge of the dynamics of ecological restoration in grasslands is in full development, which is why the evaluation of the changes that occur in floristic wealth and abundance, ecological condition and animal carrying capacity in two areas excluded from grazing in August 2015 in the Nor-Yauyos Cochas Landscape Reserve, Peru, was proposed. The agrostological evaluation used the method of linear transection of interception points in 32 transects of 10 meters. The evaluation began in the year of the grazing exclusion and at the end of the 2016 low season and continued until the 2017 low season. Wealth and abundance showed significant increases only in the rainy season (p = 0.0125), no significant difference in ecological condition or animal carrying capacity was observed between seasonal periods, but between plots for p=0.001. In conclusion, the practice of exclusion of grazing did not show a rapid response in the change of biological indicators, which suggests that the evaluation should be carried out in a longer time.
