Soil adjusted vegetation index to estimate management effect at North Coahuila

Effects on vegetation cover (VC) are evaluated calculated Soil Adjusted Vegetation Index (SAVI), showing change trends between 2016 and 2020 under different management in six properties of the APFF, Ocampo, Coahuila. Index values and the average generated n = 348 832 data, showing no normality. Kruskal Wallis H test did not indicate significant differences between the estimated values of terrains. Private lands with conservation management had high SAVI values indicating higher CV, community lands with livestock management had low SAVI values and lower CV. From 2016 and 2017 there were significant differences (H, P < 0.01) they were statistically similar, for 2018 to 2020 different, in 2019 the highest SAVI values were recorded. The Index was useful for covering large areas of land in arid and semi-arid regions, making it possible to detect changes in CV for analysis and resource management planning.
