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. Browse our collection of digitized technical notes or use the links in the tables below.

For assistance accessing technical notes, including those not yet linked from this page, please contact the BLM Library at

Print copies of select technical notes may be available for purchase; for more information, contact the BLM's Printed Materials Distribution Services (PMDS) at or visit the PMDS website. 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.
