What roles do they have in the ecosystem?

Commensal or parasitic species (or larger taxonomic groups) that use this species as a host
  • Mesocestoides sp. (Order Cyclophyllidea, Class Cestoda)
  • Oochoristica osheroffi (Order Cyclophyllidea, Class Cestoda)
  • Physaloptera abjecta (Order Spirurida, Phylum Nematoda)

Do they cause problems?

There are no known adverse effects of these snakes on humans. (Feller, 1996; Hammerson, et al., 2007)

How do they interact with us?

Glossy snakes eat rodents and lizards, therefore controlling potential pest populations. (Hammerson, et al., 2007; Rodriguez-Robles, et al., 1999)

  • Ways that people benefit from these animals:
  • controls pest population

Are they endangered?

Though currently not considered threatened, some populations of glossy snakes have been progressively reduced due to agricultural development and urbanization. No conservation plans have been developed to maintain populations due to this species' stable distribution, number of sub-populations, and population sizes. However, some populations are protected as they live national and state parks. ("Arizona Elegans", 2012; "U.S. Fish & Wildlife Service", 2012; Hammerson, et al., 2007)

Some more information...

It has been suggested that this species includes a subspecies, Arizona elegans occidentalis. (Hammerson, et al., 2007)
