This collection includes two report series published by the BLM Alaska State Office: technical reports and open file reports. Technical reports present results of research, studies, investigations, literature searches, testing, or similar endeavors on a variety of scientific and technical subjects. The results presented are final, or are a summation and analysis of data at an intermediate point in a long-term research project, and have received objective review by peers. Open file reports present results of inventories or other investigations on a variety of scientific and technical subjects that are made available to the public outside the formal BLM-Alaska technical publication series. Open file reports can include preliminary or incomplete data and are not published and distributed in quantity.
