BLM Technical Notes
Begun in 1966 as a forum for BLM employees, technical notes encompass resource management topics such as ecological surveys, inventories, and monitoring; analytical methods and techniques; applied research; resource assessments; risk management; and model interpretation and estimation. Each technical note deals with a single subject. We are in the process of digitizing the technical notes. Digital availability currently extends back to technical notes numbered in the mid-200s, published in the mid-1970s.
For assistance accessing technical notes, including those not yet linked from this page, please contact the BLM Library at blm_library@blm.gov.
Print copies of select technical notes may be available for purchase; for more information, contact the BLM's Printed Materials Distribution Services (PMDS) at BLM_OC_PMDS@blm.gov.
Please note that some numbers were not assigned and have been omitted from this listing. Some technical notes, especially early ones, listed subject headings rather than a formal title and did not credit an author.
The BLM Technical Notes listed below are organized as follows:
