| Zusammenfassung: | Mexico is the most important center of concentration of genera and species of cacti, most of which are endemic (73 and 78% respectively). Most of the species occur in the arid or semiarid regions of the country, especially in the southeastern portion of the Chihuahuan Desert, including the Queretaro-Hidalgo Arid Zone. Many of the species are under collecting pressures and their habitats are being destroyed. In addition, these have a limited ability to reestablish demographically after a disturbance event. Consequently, a significant number of mexican cacti are listed as endangered. |
