This document reports preliminary findings and summarizes methods used in monitoring the threatened species Lupinus oreganus on the BLM Roseburg District. In 2012, the tenth year of the project, we monitored L. oreganus populations by assessing foliar (leaf) cover (a measure of abundance) and counting racemes at a total of six sites on the Roseburg District. Data collected this year are from the eighth year of monitoring at Dickerson Heights and Stout’s Creek, the ninth year of monitoring at China Ditch, and the tenth year of monitoring at Loose Laces, Letitia Creek, and Callahan Meadows.
