This document is a report about the threats to desert tortoise populations. The report discusses the use of data to make management decisions, desert tortoise biology, specific threats to tortoise populations, and cumulative threats to tortoise populations. Specific threats to tortoise populations include agriculture; collecting by humans; construction activities; disease; drought; energy and mineral development; fire; garbage and liter; handling and deliberate manipulation of tortoises; invasive plants; landfills; livestock grazing; military operations; predation/raven predation/subsidized predators; non-off road vehicle recreation; roads, highways, and railroads; utility corridors; vandalism; and wild horses and burros.
