This past week, we took a trip down to the Umpqua River basin near Roseburg, OR to monitor Lupinus oreganus (Kincaid's lupine), which is a federally threatened species and an obligate host plant to the endangered Icaricia icarioides fenderi (Fender's blue butterfly). This area is home to the southernmost populations of L. oreganus. Lupinus oreganus typically occurs in native upland prairie habitat. With it's large, upright inflorescences and dark green palmate leaves, it's hard not to admire the grandeur of this plant. The flowers of L. oreganus range in color from bluish/purple to yellowish or cream.

The goal for this project was to monitor 6 different sites where L. oreganus populations exist on land managed by the Roseburg District BLM. These sites have been monitored by IAE for the past 12 years in order to track changes in these rare southern populations and their responses to management treatments. Each morning began with a healthy dose of Oregon Sunshine (a local coffee shop in Canyonville) and a short (or sometimes long) trek out to one of our 6 field sites.
