| Mexico's xerophilous thickets and semi-desert pastures are located in arid and semi-arid areas that account for half of our national territory. |
| Sand dunes and higher river terraces were still preserved at that time and supported xerophilous vegetation. |
| Everywhere one feels the influence of the Mediterranean and particularly on the specific xerophilous flora and fauna of the region. |
| While some xerophilous grasshoppers became scarce within the shelterbelt system, others, e.g. Calliptamus italicus, increased in importance. |
| There is no cultivation on the plain, which is to a large extent covered with long sarpat grass and other xerophilous plants. |
