A Sea of Blue at Maple Creek Meadow

This photo of the view east was taken from about the same spot as the ones I used in my previous two reports about Maple Creek Meadow—why break tradition? The little opening on the nearest ridge is Rabbitbrush Ridge where I went the previous week (see More Exploration Near Grassy Glade) and which also has purple milkweed, rubber rabbitbrush (Ericameria nauseosa), northern buckwheat, and bluefield gilia, all seen here.

With the forecast predicting warm summer weather on the way, I figured it might be my last chance to get out to see the peak bloom of purple milkweed (Asclepias cordifolia) at lower elevation meadows without roasting. I had been wanting to return to what I named “Maple Creek Meadow” as I’d only been there twice before: first on a hot day in July (see Another New Milkweed and Monarch Site!) when most things were finished and the following year on a cloudy day in May (see Surveying Milkweed at “Maple Creek Meadow”) when many plants were just starting. So I was due for a sunny but cool day in the middle of the season and headed out to the Rigdon area of southeastern Lane County on June 17.

More Exploration Near Grassy Glade

The most floriferous spot at Rabbitbrush Ridge is a small draw next to the dike. No doubt this area funnels most of the surrounding moisture to the mass of northern buckwheat (Eriogonum compositum), frosted paintbrush (Castilleja pruinosa), varifleaf phacelia (Phacelia heterophylla), bluefield gilia (Gilia capitata), ookow (Dichelostemma congestum), and Oregon sunshine (Eriophyllum lanatum).

Candelabrum monkeyflower is a delicate annual that prefers openings among shrubs where there’s little competition.

On Wednesday, June 10, we had a day off from the rain (not that I’m complaining about rain in June anymore!), so I took advantage of it to head back to Grassy Glade and check out one more opening I hadn’t been to yet and see how the purple milkweed (Asclepias cordifolia) was doing.

First I made a few stops to collect seeds: silvery lupine (Lupinus albifrons) was ripening on the north side of Hills Creek Reservoir, and there was still some seed of Hall’s lomatium (Lomatium hallii) along the cliffs west of the reservoir. I also got a good collection of seeds of the annual miniature lupine (Lupinus bicolor), which I’d spotted growing abundantly along the road right under the guard rails. In this same area, the paintbrush (a mix of Castilleja hispida and C. pruinosa) was still blooming as was the Oregon sunshine, including a lovely pale yellow-flowered plant I’ve watched for years. I’ll be back for seeds of those later in the summer—Castilleja blooming in an area I’m restoring on my property are the progeny of these plants, growing successfully in mats of Oregon sunshine, some of which were also grown from seed collected here.

Followup Milkweed Count at Coal Creek Bluff

One of the beautiful madrones (Arbutus menziesii) that grace the bluff. Coal Creek can be seen cutting through the forest down below.

From lower down the slope, I got a peek-a-boo glimpse of the small waterfalls upstream along Coal Creek. Unfortunately, a closer look would require climbing down some very steep banks.

Saturday, May 9, was a beautiful day but around 80°—much hotter than I’m used to this time of year. I had hoped to get up to a high enough elevation to be a little more comfortable, and I was really hoping to see the very early mountain flowers. My plan was to try to get up to “Heavenly Bluff” to see the Siskiyou fritillary (Fritillaria glauca), a very early bloomer. I hadn’t been there for 6 years. If I couldn’t get that far, I would go to Bearbones Mountain, which I would pass on Road 5850. It’s another site for the fritillary, though much less floriferous. Unfortunately, right after I turned onto Road 5850, I came upon a number of fallen trees. It was another 3 miles or so to get to Bearbones, so I was not going to add over 6 miles of road to my hike. A little snow in the ditch also made me wonder if there might still be some snow blocking the road farther ahead even without downed trees. The shady section of road on the north side of Spring Butte seems to hold snow longer than the rest of the road. 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 »

Three Trips in a Row to Rigdon

The mock orange (Philadelphus lewisii) was in full fragrant bloom at Many Creeks Meadow and attracting lots of snowberry checkerspots. I can almost still smell the heavenly fragrance!

On Sunday, June 16, I hiked up the Youngs Rock trail, bushwhacking in from a meadow between Road 2129 and the trail that John Koenig and I named Buckbrush Meadow last year. Then on Wednesday, June 19, I went to Grassy Glade with Maya Goklany of Walama Restoration and two volunteers, Alicja and Sabine. We also explored the lower openings, “Rocky Glade” and “Mock Orange Glade.” Finally, on Friday, June 21, I headed over to “Many Creeks Meadow” for an afternoon of seed collecting before camping at Sacandaga Campground for the weekend (more on that later).

Here are some photos from those trips. Read the rest of this entry »

Counting Purple Milkweed at Grassy Glade

A cedar (AKA juniper) hairstreak waiting for the milkweed buds to open.

Last year we did a lot of milkweed counts, but somehow we never counted the main population at Grassy Glade, even though we all went there many times. So on May 30, Maya Goklany, volunteer coordinator for Walama Restoration, and I went to Grassy Glade to look at the milkweed. Thankfully the road in was fine, and it didn’t look like there was much storm damage there. The purple (or heartleaf) milkweed (Asclepias cordifolia) was just barely starting to bloom. Only a few plants had any open flowers, although several cedar hairstreaks were hanging around, hoping for some nectar from these butterfly favorites. Read the rest of this entry »

A Day of Uncommon Ferns and Sedges

Larkspur covered the mossy rocks of Sacandaga Bluff.

On May 3, John Koenig and I went back to Rigdon to check out what I now call Sacandaga Bluff, a wonderful rocky area hidden away between the Middle Fork of the Willamette River and Sacandaga Campground. Last year, Ed Alverson had told us he found a population there of Sierra cliffbrake (Pellaea brachyptera), an unusual fern found more commonly to the south. It is one of my favorite ferns, and I’ve written about finding new spots for it in Lane County several times. I went to this spot a couple of times later year, and once earlier this year (see last report), but I still wanted to see it in its high spring bloom. Read the rest of this entry »

Further Rigdon Area Meadow Exploration

I’ve been so busy, I haven’t been able to keep up with the blog. I went out another 16 times since my last report in July, but I just didn’t seem to have the time to post. So—now that the year is just about over—I thought I’d try to at least post some photos from the most interesting of those trips—many were just seed-collecting trips to familiar places for the restoration work on my own property.

Looking for more purple milkweed (Asclepias cordifolia) sites in the Rigdon area of southeastern Lane County was still one of my top priorities for the year. While I wasn’t able to find milkweed in most of them, I did find some interesting spots.
 

July 6

Purple milkweed dying back at the quarry meadow.

Crystal Shepherd, who worked as a botanist in the Middle Fork district last year, told me about a site where she found “one lonely Asclepius” last year. It was a very small opening above an old quarry along Youngs Creek Road 2129. I decided I’d better check it out it myself. I had looked at the meadow alongside the quarry many years ago in early spring but had never been back, even though it is just above the road that I’ve driven up countless times. I was thrilled to discover there was actually milkweed in the quarry meadow itself. I only spotted 10 plants, but some were already largely collapsed on the ground, so there may well be more than I saw. Before the quarry tore into the meadow, there might have been a much larger population. There were also a lot of other nice wildflowers in this meadow, including tons of tall bluefield gilia (Gilia capitata) going to seed (but not ripe yet—darn!) and quite a bit of blooming western rayless fleabane (Erigeron inornatus), what I’ve come to feel is a regular associate of purple milkweed.

Searching for Monarchs at Grassy Glade

On June 27, John Koenig and I went to Grassy Glade with Jenny Lippert, Willamette National Forest botanist, to see if there was any more monarch activity. Jenny hadn’t been there for a number of years, so I was quite interested to find out if she thought the population of purple milkweed (Asclepias cordifolia) was expanding or contracting. We’ve had a number of discussions about whether this species is moving northward—possibly due to climate change—or if it was formerly more common back when Native Americans kept the area more open by burning and is now decreasing. The answer to this question would be of great help in deciding how best to encourage more milkweed in the Rigdon area. She seemed certain there was more milkweed in the main area by the road and that she hadn’t seen it before closer to the large, open meadow. While anecdotal, this was great to hear.

We found a few eggs but not as many as I was hoping to see. As on my previous trip, a swallowtail and some smaller butterflies were enjoying the lovely milkweed blossoms. Soon, we were joined by a monarch! It was a male, and I wondered if it was the same one I had spotted a couple of weeks before. Where was the female who had laid the eggs?

More Milkweed Near Grassy Glade

Molly and Joe both carried butterfly nets all day, hoping to be able to tag an adult monarch. This Lorquin’s admiral was the only butterfly to make contact with a net. It must have found something tasty on the net and joined us while we ate lunch on the banks of Coal Creek.

On June 15, Molly Juillerat (botanist but now deputy ranger at the Middle Fork District), Joe Doerr (wildlife biologist for the Willamette National Forest), and I went back to Rigdon to do some more exploring. First, we headed out to see the purple milkweed (Asclepias cordifolia) at Coal Creek Bluff. Neither Molly nor Joe had been there before, so I’d been hoping to take them there for some time. We took a relatively short spin around the slope, stopping to check on the milkweed. There was no sign of eggs or caterpillars yet, so I’m still not certain if the monarchs know about this small population. Although the slope was pretty dry, there were plenty of nectar plants to be had if any monarchs did show up. The milkweed was in fading bloom, but fresh northern buckwheat (Eriogonum compositum), Oregon sunshine (Eriophyllum lanatum), bluefield gilia (Gilia capitata), and elegant cluster-lily (Brodiaea elegans) added some color to the mostly brown slope.
