Habitat of Ruby

Ruby has worked with the Arizona Game and Fish Department and the U.S. Fish and Wildlife Service to better understand and protect the area’s wildlife. A big-game fence was constructed around the perimeter to allow access for wildlife and help protect the property’s ecosystem.

Several film companies have expressed interest in documenting the biodiversity of Ruby, and one group, Oxford Scientific Films from the U.K., produced a video, “The Ghosts Of Ruby” which airs regularly on PBS and Discovery channels. Others use it for filming drama and photogenic properties.

Plans are being developed to survey and document the wide variety of plants and animals of the area and for the next several years, we will be working with biologists from several agencies and conservation groups to understand in greater detail Ruby’s potential as a wildlife refuge.

A colony of Mexican Free Tail Bats inhabits Ruby’s abandoned mine shafts from May to September each year. Estimates of the colony range from 90,000 to as high as 150,000 animals , representing a nightly appetite for up to 1/2 ton of insects.  This is considered a maternal colony and they produce their young in June and leave for parts south in late August.  Their nocturnal schedule varies with storm, wind and insect life.
