  1. Notice: H′ is the Shannon-Wiener index, R is species richness, E′ is the Shannon evenness, Prosopis invasion levels/habitats (PT, PM, NIWL, and OGLs), Df is the degree of freedom, * significant at P < 0.05, ** is the high significant at P < 0.05, *** is the very high significant at P < 0.05; the same letters indicate insignificant variations at P < 0.05
