Human-induced landscape transformations have important implications for the maintenance of biodiversity. If any such loose cover ever mantled the Edwards Plateau, it has long since been carried away by erosion, although remnantal summit areas in the northwest portion of the plateau, in the transition zone adjacent to the High Plains, are characterized by a cover of unconsolidated silty materials. Today, however, changes to the natural flora and fauna have resulted in a scrub forest with too many deer for the area to properly support. total impact is the period is generally dryer from east to west. Our results indicate that in the Edwards Plateau, HILF grazing tactics should be employed during the major part of the growing season (May-September) to allow long rest perios for both the soil and vegetation to recover. The Plateau Railway Station thermal comfort survey indicated that passengers' satisfaction with indoor air humidity was the lowest and report that the air is too dry (Yang et al., 2011, Zeng and Yu, 2020).Air humidity has a variety of direct and indirect effects on human comfort levels (Liu et al., 2020; Griin et al., 2012).The severity of the symptoms increases with prolonged exposure to this .
