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.

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 »

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.

Butterflies Galore at Grassy Glade

The west end of the ridge can’t be seen from most of the ridge, but this is where most of the purple milkweed is found.

After my first look at the rocky slope north of Grassy Glade (see Exploring Near Grassy Glade), I was anxious to get back when the milkweed was in bloom (and the weather was better!). On June 11, I drove to Grassy Glade and walked directly to the end of Road 262 to where I could climb down to what I’m now calling “Rabbitbrush Ridge.” Since the thunderstorm drove me away before I was able to make it to the far end of the ridge on my earlier trip, I headed along the ridge to west end rather than poking around down the steep slope. That turned out to be the right thing to do. After finding a few individual plants scattered along the ridge, I was thrilled to come upon a decent-sized population of milkweed blooming in a scree just beyond the north-south dike I had thought marked the end of the ridge. This area was a bit more protected and more gravelly than rocky, so perhaps more to their liking. Read the rest of this entry »

Return to Grassy Glade and Many Creeks Meadow

While most of the milkweed is in some openings in the woods, a small number of plants grace the north end of Grassy Glade. Parts of the large meadow were already dried out, while others remained green and floriferous. Remnants of a forest fire can be seen on the hills to the south.

I suggested we look for seedlings of milkweed, and Sasha quickly spotted this clump. You can see the purplish, long-petioled cotyledon leaves still evident at the bases of the tiny plants.

In spite of not receiving a Monarch Grant from the National Fish and Wildlife Fund this year, Walama Restoration Project is still working on collecting data about the milkweed and monarch sites in the Rigdon area. Hopefully, they’ll have better luck next year. Maya Goklany is the volunteer coordinator for Walama and has already started taking volunteers out to count purple milkweed (Asclepias cordifolia) at Monarch Meadow. We had been wanting to go out to Rigdon together sometime to survey the milkweed and finally had a chance on Sunday, May 27. I invited Sabine Dutoit along, and Maya brought her friend Sasha. How wonderful to hang out with a great group of plant-loving women! It was a gorgeous day to be out botanizing. It was also a great day for Memorial Day Weekend camping trips, and there were more people along the lake and in the general Rigdon area than I think I’ve ever seen before. We even ran into other folks up at Grassy Glade, our first stop. But most of our day was spent enjoying the peace and quiet with only the pleasant company of each other and the butterflies, birds, and bees. Read the rest of this entry »

Exploring Near Grassy Glade

A lovely madrone (Arbutus menziesii) grows on the backside of the rocky ridge.

On my most recent trip (see Surveying Milkweed at Maple Creek Meadow), I had seen an intriguing rocky slope to the east. I realized it was one of the sites in the Rigdon area of southeastern Lane County that I had made a note to survey. It was just north of Grassy Glade, where there is a good population of purple milkweed (Asclepias cordifolia), so I decided for my next outing, on May 15, to check it out, as well as some other openings in that area.

Surveying Milkweed at “Maple Creek Meadow”

This is the same view across the meadow, with the same milkweed and rabbitbrush, as I posted last year. You can see an open, rocky slope on the near ridge. I visited it a few days later. Grassy Glade is nearby on that ridge but can’t be seen from here. Unfortunately, the clouds never really broke, so we couldn’t see the view of Diamond Peak.

Last July, I discovered a new site for purple milkweed (Asclepias cordifolia) in the Rigdon area (see Another New Milkweed and Monarch Site!) and dubbed it “Maple Creek Meadow” since the nearest named feature is Maple Creek. I had been looking forward to getting an earlier look at it but wanted to wait until the milkweed had at least emerged. Since I had seen it coming up in some of the nearby sites, John Koenig and I decided to head up there on May 11. Knowing where I was going and how great a place it is, I found the boring, 1.7-mile walk up the bermed-off Road 217 much more pleasant than I did last year when I was wondering all the while if it would be worth it. We had hoped the morning clouds would burn off, but we were under clouds most of the day, so we didn’t get to see many butterflies. Read the rest of this entry »
