Pituophis deppei * (14)

Thamnophis melanogaster * (15)

Crotalus aquilus * (16)

All six of these species are country endemics and note that their EVS values range from 14 to 16.

In each of the three physiographic regions in Querétaro, the largest distributional grouping consists of country endemic species. In addition, the high vulnerability species in each region also are country endemics. Thus, both RHP measures indicate that the species of greatest conservation significance are all country endemic species. These results are important to recognize in any efforts to protect these creatures (as discussed in detail below).
