Looking south to Calapooya Mountains from the large (and steep!) lower meadow, you can see snow still along the crest. The large white area to right end is Bristow Prairie. While I love seeing snow lingering at the end of May, I hope it will have melted by the time I have to lead a hike there later in the month.

As I drove along the reservoir in the morning, a large butterfly caught my eye, so I pulled over immediately and waited for it to return. The gorgeous tiger swallowtail rewarded me by landing and sitting perfectly still on a stunning lupine. Calendar shot for sure!

Since there is still some snow at higher elevations, and the rain is fueling great flowers down low, on May 31, I decided to head to the large lower meadow off the Youngs Rock trail. I went down there twice back in 2016 (see Exploring Meadows Below Youngs Rock) but hadn’t returned since. After my usual stops along Hills Creek Reservoir to see the gorgeous paintbrush (Castilleja hispida and possibly pruinosa), I stopped at the bathroom by the bridge and noticed a lot of activity under the bridge. When Nancy and I stopped there the week before (see Spring Again at Coal Creek Bluff), I was surprised at the absence of swallows since we had seen some tree swallows along the cliffs. But on this trip, there were numerous swallows, some tree swallows but mostly cliff swallows. You can recognize cliff swallows by their buffy back and the creamy spot on their head and nape. Both tree and cliff swallows have a much shorter tail than barn swallows. They appeared to be rebuilding their nests under the north side of the bridge. Or maybe they start new ones every year, I don’t know. I guess there’s not enough room left in my brain to learn about birds after studying plants and butterflies so much! I spent a while watching them and listening to their unusually squeaky chattering—definitely different from the tree swallows that live in my meadow. Read the rest of this entry »

Looking north across the slope to Moon Point and Youngs Rock. I hadn’t seen such a pretty show of monkeyflower on my past visits.

On Wednesday, May 25, Nancy Bray accompanied me on a trip to the place I named “Coal Creek Bluff.” I had heard that the Forest Service would be further decommissioning the old Road 210 that I use to access the site to protect Coal Creek from further erosion. I wasn’t sure what this entailed, so I was anxious to find out if I would still be able to access this lovely spot, one of our purple milkweed (Asclepias cordifolia) sites in the Rigdon area. The last time I was there (in 2020, see Followup Milkweed Count at Coal Creek Bluff), I couldn’t make it to the last place you can park before a big washout on the old road. I managed to scratch my brand new car trying to turn around after coming upon a fallen tree. So this time, I just decided to park at the old gate where there is a large area to turn around and do the extra walking. I was surprised to find the road completely clear all the way to the final parking area. Darn! We could have shortened our walk. Next time I’ll know. Read the rest of this entry »

Few flowers are as gorgeous as gentians in full bloom. While most of these were single-flowered, a number of them had three flowers to a stalk. The Cascade grass-of-Parnassus (Parnassia cirrata) was also coming into bloom, although these three buds hadn’t opened yet.

After several years of bad timing, I finally hit the perfect time to collect milkweed seed at Grassy Glade.

Since the bog gentians (Gentiana calycosa) had only just started on my previous trip to Warner Mountain (see Warner Mountain Botanizing), I was determined to get a better look at them, so I returned by myself on August 9. By this time, the Middle Fork Complex fires had started (after a July 29th thunderstorm went through the district), and finding a day when the smoke wasn’t too bad was difficult. But I was getting tired of being stuck at home, I figured it would only get worse as the summer wore on, and the day seemed like it might be okay. I drove through heavy smoke between Lowell and Westfir, just south of the Gales Fire, and was questioning my plans, but it wasn’t so bad heading south along Hills Creek Reservoir. My first stop was to Big Pine Opening to look for purple milkweed (Asclepias cordifolia) seed, but it had already all blown away, so I continued on to Grassy Glade, a couple of thousand feet higher in elevation. Not only were the milkweed pods still cracking open, but I was above the smoke, so I was very pleased and spent a little while there collecting seeds and wandering around before continuing on to my main goal.

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.

Beautiful spreads of woodland phlox (Phlox adsurgens) bloomed along the edge of the both the paved road and the gravel one we walked on.

On Sunday, May 9, I went for my first outing in almost a month—just too much to do at home, and the drought discouraged me from going to my favorite seepy spots that I’d planned on, like Deer Creek. I was really happy to be able to go out with my friend John Koenig, whom I hadn’t seen since last summer. Being vaccinated now is such a relief, and it is wonderful to safely hang out with others who are also vaccinated (if you’re hesitating—don’t!). We decided it might still be too early to try to go to higher elevations, even with all the warm weather, so we headed down to Hills Creek Reservoir and the Rigdon area to check out some of our favorite haunts. We had some vague plans but mostly just played it by ear, stopping wherever looked interesting. We ended up spending lots of time watching butterflies. We also had to warm up our “botany muscles,” trying to remember forgotten names.

At Everage Flat, we spent quite a long time watching butterflies on the Pacific dogwood flowers. This echo azure is enjoying the fresh flowers in the center of the showy bracts.

After a look at the gorgeous silvery lupine (Lupinus albifrons) at the north end of the reservoir and a brief stop to admire the blooming paintbrush on the cliffs along the reservoir, I pulled into Everage Flat Picnic Area (just south of the intersection of Youngs Creek Road 2129) as it occurred to me that we should see if the Howell’s violet (Viola howellii) was still in bloom. I expected it to be a very quick stop, so I even left my (all-electric) car on. But upon seeing that the large Pacific dogwood (Cornus nuttallii) in the sunny center of the picnic area was in perfect bloom and appeared to have butterflies flying around it, I parked the car for real. Our 2-minute stop turned into a 2-hour one! Read the rest of this entry »

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.

Two caterpillars eating flower stalks of rose checkermallow. Apparently, their color depends partly on what they are eating. I think both are gray hairstreaks (but correct me if you think otherwise!).

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.

Sadly not a monarch but a worn California tortoiseshell on purple milkweed.

On Memorial Day, May 25, I made the long drive down to the North Umpqua to check out the population of purple milkweed (Asclepias cordifolia) along Medicine Creek Road 4775. I was a little disappointed to find it was just starting to open. I think the cool weather of late had slowed things down because Big Pine Opening was at about the same stage weeks ago, and although it is lower elevation, it is also much farther north. But although the milkweed wasn’t attracting many insects, there were plenty of plants that were.

A silver-spotted skipper was one of many insects nectaring on silverleaf phacelia.

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 »

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 »
