Exploring New Milkweed Meadows in Rigdon

Jenny studying the plants in the still-green seep along the edge of the west meadow. The lush shrub at the top of the photo was a very healthy poison oak!
Back in February, I was invited to a Zoom meeting set up by Walama Restoration and the Middle Fork Ranger District to discuss ongoing restoration projects in the area and further work on purple (or heartleaf) milkweed (Asclepias cordifolia) and monarchs (if their population bounces back) in the Rigdon area. At that meeting, I learned that last summer the district hired some surveyors to check out special habitats (I think that includes anything that isn’t forest!) on the west side of Hills Creek Reservoir and the Middle Fork of the Willamette. They surveyed a number of south-facing openings that I’d seen on Google Earth but never explored. I was very excited to hear that they found two new populations of milkweed! And these were farther north than any of our other sites, making them the new northern boundary of its range. Jenny Moore, the current district botanist, didn’t know much more about the sites or the milkweed itself there, so we discussed going up there together to see them for ourselves once the milkweed started blooming.
After seeing the milkweed starting to flower at Big Pine Opening a few weeks earlier (see Relaxing Day in Rigdon), I figured it was time. The weather was supposed to get hot again, so I was happy that Jenny was able to go out with me on Friday, May 28 before it got too hot for a steep bushwhack up low-elevation, south-facing, rocky meadows around 600′ above the road.
