Conservation genetics is the application of the tools and concepts of genetics to the conservation of biological resources. Once too sophisticated and expensive for routine use, the tools of conservation genetics are now widely used to address many complex management questions. These novel methods of analysis can augment assessments made with traditional methods and can bring new information to light. The U.S. Geological Survey (USGS) is well suited to provide scientific information and expertise using these tools to support the management of biological resources.
