Studies have shown that raven populations in the Mojave Desert have dramatically increased over the past three decades. According to Dr. William Boarman, it is speculated that this increase is due to anthropogenic activities. This growth in population of the common raven is thought to be adversely affecting the threatened species of the desert tortoise.

The Redlands Institute has been studying the expansion of The National Training Center at Fort Irwin, located northwest of Barstow, CA, to determine what effects the expansion will have on the desert tortoise and raven population. GIS plays an integral part for identifying areas of raven predation on the desert tortoise.

The goals in creating a GIS for raven management are: (a) create a Personal Geodatabase to standardize data collection, (b) standardize raven data collection methods for field crews, (c) show how to create ArcPad forms to implement data directly into GIS.
