BRD was created when Secretary of Interior
Bruce Babbitt transferred most of the research biologists from the various Bureaus of the
Department of the Interior. In 1993, Babbitt established the National Biological Survey (NBS), staffed with more than 1,300 researchers and support personnel reassigned from the Fish and Wildlife Service, with additional scientific personnel from the National Park Service and other Interior agencies. However, Congressional opposition threatened to abolish the new bureau—which now "contained a substantial portion of all the scientists in the Interior Department. Babbitt had put most of his eggs in one basket." In 1995, Babbitt renamed the NBS as the National Biological
Service to allay opposition, but Congressional threat to the scientific organization persisted. In 1996, the National Biological Service was transferred to become the Biological Resources Division of the USGS. The BRD was renamed as the Biological Resources
Discipline in 1999 as part of USGS Director
Charles Groat's Strategic Change planning. ==General principles==
