NPSO Trip to Grassy Glade

The group checking out the monkeyflower and annual clovers in the areas of Grassy Glade that were still moist.
On Saturday, June 3rd, I took a group of folks attending the Native Plant Society of Oregon‘s Annual Meeting (first one since the pandemic!) to Grassy Glade and Staley Creek Bridge. We didn’t have as much time as I would like for a field trip as we had to get back to Eugene in time for the banquet and other evening festivities. But it was a perfect day for a field trip, and we had a chance to look at some of the diversity of the Rigdon area, exploring both the meadows and dry forest at Grassy Glade and the wet creekside habitat and lusher forest along Staley Creek. Unfortunately, the purple milkweed (Asclepias cordifolia) that I had hoped to show everyone still wasn’t in bloom, and in fact didn’t look much farther along than it had been the week before on my prehike (see Planning Trip to Grassy Glade). It was new plant for many people, however, and they enjoyed the handsome foliage. Hopefully, everyone found something new and interesting. Here are some highlights of our trip.

White-tip clover (Trifolium variegatum) is a common annual clover of seepy meadows, but it is often quite tiny and easily overlooked.

This interesting looking underwater growth in Staley Creek is Nostoc parmelloides, a cyanobacteria that forms colonies in cold creeks. I hadn’t noticed it on my previous trips but had seen it up in the Calapooyas a few years back (see More Discoveries along the Calapooya Crest). Tiny midge larvae develop in the flattened colonies.

Some of us were lucky enough to spot the dipper in the usual spot right where the water plunges down at the narrowest part of the creek. Unfortunately, it flew off before everyone got to see it. I could not relocate the nest that I had seen on previous years (see More Exploration Near Grassy Glade).
Planning Trip to Grassy Glade

I do hope that some of the beautiful purple milkweed will be in bloom on our upcoming trip to Grassy Glade!
On Saturday, May 27, I headed out to the Rigdon area to plan the field trip I’m leading for the Native Plant Society of Oregon Annual Meeting the following Saturday. I want to give people a taste of the interesting plants in this area that are more common to the south, especially the lovely purple (or heartleaf) milkweed (Asclepias cordifolia) that I’ve written about so many times. I’ve been crossing my fingers that we will see some in bloom somewhere, but with the crazy shift in weather this spring, it’s hard to anticipate how the plants are going to react. There are lots of great places in the Rigdon area, but I wanted to know which would work best for our non-trail field trip.
I drove straight to Grassy Glade and parked along the side road near the beginning of the meadow. I did a quick spin through the meadow, which was half baked and half moist. On the road in, I had noticed some of the potholes were partly filled with water. Obviously, some of the thunderstorms that I’d heard had occurred out here had blessed the area with some much-needed moisture—there hasn’t been a drop for almost three weeks at my house. My guess is that some of the meadow had already dried out before the rain, while the moister parts had been refreshed before the annuals died. Spring gold (Lomatium utriculatum) and many species of clover (Trifolium spp.) had started along with the cute narrow-leaf owl’s clover (Castilleja attenuata). Read the rest of this entry »
Milkweed is Up and Dippers are Out

One of the milkweeds was close to the cliff edge above the quarry. Thank goodness for the long zoom on my camera so I could take the photo from a safe distance from the edge.
On Monday, May 4, I headed out to the Rigdon area southeast of Oakridge to check on the purple or heartleaf milkweed (Asclepias cordifolia). At home, my little seedlings had been germinating, and some of last year’s seedlings were reemerging, so I was pretty sure the milkweed would be up at Big Pine Opening. I was surprised to see how tall some of the plants were, and several even had a few open flowers. I relocated the “chia pet” milkweed plant(s) from last year (see Three Trips in a Row to Rigdon). It was still growing in the same bizarre manner. I’m really puzzled by this odd plant, but I’ll just have to watch it as it develops. I wonder if it will flower eventually.

Last year’s chia pet-like clump of purple milkweed is up again at Big Pine Opening. Comparing it to last year’s photo, it looks like it has fewer, larger shoots, but it is still way more congested than a normal plant.
Big Pine Opening is an open slope at the intersection of Road 21 and gravel Road 2135. On the side facing the gravel road, the hillside was been carved out for a quarry. Unfortunately, the milkweed only grows on the top of the slope on the side above the old quarry. After seeing milkweed growing in the relics of a quarry at “Maple Creek Meadow” (see Surveying Milkweed at “Maple Creek Meadow”), I’d wondered whether the milkweed might be able to grow in the quarry itself at Big Pine Opening. After checking out the milkweed at the top, I went back down to the road and walked partway up the talus in the quarry—I wasn’t up to the difficult task of going high up the loose rock, but, with my binoculars, I was able to spot two patches growing in the gravel along the north side, in the partial shade of a couple of young ponderosa pine. There appeared to be at least a dozen plants large enough to be in bud. One more plant was growing in the main slope. I’m not sure if I can get close enough to the plants for a good count, but I’m just pleased the population is expanding into the quarry side. I suspect there might have been more milkweed on that side before the quarry was created, so maybe they are repopulating below where they once grew. Read the rest of this entry »
