Butterflies and Moths at Castle Rock and Cougar Reservoir
One of the field trip sites for the recent Native Plant Society of Oregon annual meeting was Castle Rock. It’s a relatively low-elevation rocky knob near Cougar Reservoir. When I checked the list of all my hiking trips, I discovered I hadn’t been there in 10 years. I’m not sure why it fell off my radar because I used to go every year. After so many weeks without rain, I figured it might be really dry and not very interesting, but I decided to check it out anyway, and I’m so glad I did. On June 16, I headed to Cougar Reservoir first. I was surprised there was still water dripping down the cliffs near the dam and into the concrete ditch where there were some tadpoles swimming around. That was also a surprise. I’ve been seeing a few little black and white moths lately, Macculloch’s foresters (Androloma maccullochii), but here they were abundant, nectaring on lots of flowers but especially the abundant weedy daisies (Leucanthemum vulgaris). I was also able to get seeds of Scouler’s valerian (Valeriana sitchensis var. scouleri) a little farther down the road. On my way back from the reservoir, I passed a strip of spreading dogbane (Apocynum androsaemifolium) growing under the railing—a terrible spot to take photos with cars going by but worth it for all the butterflies and moths.

Shooting Stars are Stars of a Great Day

The population of the seep-loving beautiful shooting star was more gorgeous than I had imagined in “Mistmaiden Meadow.”
I was really anxious to get back to the steep meadow on the east side of Sourgrass Mountain after my first trip of the season (see Early Look at Meadow on Sourgrass Mountain). Exactly two weeks after the first trip, on June 13, Sheila Klest and I went to see what was in bloom. We weren’t disappointed. It was even prettier than we expected. As soon as we stepped out into the upper part of the slope, we were greeted with a sweep of pink rosy plectritis (Plectritis congesta). There was much more moisture than there had been at nearby Tire Mountain the week before (see NPSO Annual Meeting Trip to Tire Mountain). Tire Mountain is known for similar drifts of color in wetter springs, but this year was rather disappointing. Here, however, the moisture from the above-normal snowpack on Sourgrass was trickling down to the meadow and keeping it fresh in spite of a month with little or no rain. Read the rest of this entry »
NPSO Annual Meeting Trip to Tire Mountain

Mark Turner never goes anywhere without all his photography gear, and he was determined to get us all to pose for a group photo by the beautiful display of deltoid balsamroot (Balsamorhiza deltoidea)—the classic photo op at Tire Mountain. We grumbled a little, but everyone dutifully stopped, and another helpful hiker ended up taking some pictures of all of us, including Mark.

The west end of the main “dike” meadow had a very good display of Menzies’ larkspur (Delphinium menziesii). Among them were an unusual number of white- and pale purple-flowered plants.
On the last day of the Native Plant Society of Oregon‘s 2023 Annual Meeting, I took a group of plant lovers to Tire Mountain. It had been a couple of weeks since Molly Juillerat and I did our prehike (see Early Season at Tire Mountain), and it was even drier than on that trip. But I was relieved to see how many perennials were just carrying on as usual, so there was still plenty to see—even if the trail wasn’t up to its usual June splendor. While the rest of the Sunday trips for the meeting were supposed to be only half day, everyone was warned this would be a longer day and could leave early if they needed to. But the weather was just perfect for hiking, and everyone was having such an enjoyable day of botanizing that we all returned to the trailhead together. Thanks to all the participants for being such troopers! And thanks to Willow Elliot and Angela Soto for getting everyone organized in Eugene before meeting me in Lowell. Here are a few highlights.

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).
Early Look at Meadow on Sourgrass Mountain

I was surprised to find this checkerspot caterpillar wandering around some wholeleaf saxifrage (Micranthes integrifolia), which is definitely not a host food plant. Neither is Thompson’s mistmaiden, the little flowers popping up among the saxifrage leaves. There must have been some paintbrush nearby.
My last report of 2022 was about two late-season trips to hidden meadows in the area near Saddleblanket and Sourgrass mountains (see Exploring Two New Meadows). I was really excited about getting to see the meadows in bloom this year, especially the large one off of Road 140 on the west flank of Sourgrass Mountain. Having already been to nearby Tire Mountain (see Early Season at Tire Mountain), I had seen the lush green meadow from the north side of the ridge, and I knew the road was clear to Windy Pass. On May 30, Nancy Bray accompanied me, hoping for a first look at the early spring flowers in the big meadow. We had also planned to try to get to the other meadow and nearby Elk Camp and Nevergo Meadow, just a few more miles to the north, but we were stopped by a single patch of snow blocking Road 140. Luckily, we were only half a mile from the first meadow, so we walked the rest of the way up the road, which was clear of snow except in some ditches. There were still some glacier lilies (Erythronium grandiflorum) and fresh western trilliums (Trillium ovatum) in the freshly melted-out ditches and road banks on our way up.

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 »
Very Early Look at Patterson Mountain

A very early look at the wet meadow near the Lone Wolf Shelter. Snow lingered on the far side of the meadow and behind the thicket of Douglas’ hawthorns (Crataegus gaylussacia). John and I only walked over as far as where the meltwater was flowing across the meadow. No drying out here yet!

Crab spiders regularly hide on flowers (can you spot it?) awaiting unsuspecting pollinators, but I’ve never seen one on skunk cabbage before!
John Koenig will be leading a trip to Patterson Mountain for the Native Plant Society of Oregon Annual Meeting the first weekend of June, so I joined him and his wife, Deborah, for a look at the trail on May 25. We were very relieved to find the road open, although there was a large snowbank just past the trailhead parking, so we probably couldn’t have even gotten to the trail much earlier. We had to cross a couple of large mounds of snow, and there were still some patches in the meadows, so the flowering season had only just begun. While the deep snow pack was melting fast from the hot, dry May we’ve been having, I’m guessing that—unlike Tire Mountain (see Early Season at Tire Mountain)—the plants here were all protected from the heat waves by the snow. Not only is Patterson Mountain several hundred feet higher in elevation than Tire Mountain, but its more level areas are able to collect far more snow than the steep slopes of Tire.
Early Season at Tire Mountain

Spreading phlox (Phlox diffusa) is one of the treats for those who do early botanizing in rocky areas. The yellow flowers of spring gold (Lomatium utriculatum) were just starting to appear.

My first caterpillars of the year! These two checkerspot caterpillars have overwintered as small caterpillars, so they may have woken up recently. Between the spines and the distasteful iridoid glycosides in the harsh paintbrush (Castilleja hispida), they are well protected from predators and can relax in the open.
Both Molly Juillerat and I are leading trips to Tire Mountain during the Native Plant Society of Oregon‘s annual meeting next week, so on May 20, we headed up there together to see if the road and trail were open and how the plants were looking. The cold, wet April slowed spring down, but the hot and dry May weather that followed created an odd combination of the flowers barely having started, while the moss was already dried out. The typically great show of annuals, including seep monkeyflower (Erythranthe microphylla), large-flowered blue-eyed Mary (Collinsia grandiflora), rosy plectritis (Plectritis congesta), and bluefield gilia (Gilia capitata) will probably be disappointing, but hopefully the deep roots of many of the perennials like deltoid balsamroot (Balsamorhiza deltoidea) and the four different species of lomatium (L. hallii, utriculatum, nudicaule, and dissectum) will still be tapping April moisture for a while. And, of course, we are still praying for rain in June before the actual summer drought starts! Read the rest of this entry »
Staying Cool on the Trail Below Buffalo Peak

The garnet-colored flowers of the well-named long-tailed wild ginger (Asarum caudatum) were plentiful.
On Saturday, May 13, I joined Molly Juillerat, her friend Michelle, Molly’s dad Lee, and his girlfriend Liane for a hike. Given the forecast for low 90s and the late flowering after such a cold, wet April, I suggested we try the trail that goes along the North Fork of the Middle Fork of the Willamette River. It’s mostly through old-growth forest and is not far from the river, so I thought it would be relatively cool, not too strenuous, and hopefully there would be some pretty woodland flowers. I hadn’t been there since April of 2014, not long after they constructed that section of the North Fork trail (see New Trail to the Base of Buffalo Peak), and none of the others had ever hiked it, although Molly had surveyed in the area back when she was still the botanist for the district.

Late Start to 2023 Botanizing

While the center yellow lines were painted by a road crew, Mother Nature created the line along the edge of the road with a bright yellow ribbon of gold stars. They are also sprinkled all over the cliffs along Hills Creek Reservoir.

A little rove beetle(?) has gotten completely covered with pollen from the tiny flowers of skunk cabbage (Lysichiton americanus).
I almost always start my botanizing year with a trip in March to the Rigdon area in southeastern Lane County. With the cold, wet weather of March and April and the lateness of the wildflower emergence, I didn’t get out there until April 26! As I suspected, the wet spring was ideal for gold stars (Crocidium multicaule), and most everything was at least 3 weeks later than usual. Here are a few highlights.
