Neil Bjorklund at the rock garden all geared up for a day of butterfly photography.

One of the odd cat’s ears (Calochortus sp.) I’ve seen so often at Bristow Prairie. Not only does it have two extra petals, it’s not clear which species it is.

It had been almost 20 years since I’d had the opportunity to go out in the field with butterfly expert Neil Bjorklund. Neil’s website Butterflies of Oregon is the resource for the butterflies of our state, and he was a co-founder of our local chapter of the North American Butterfly Association (NABA). On June 28, we headed up to Bristow Prairie, one of my all-time favorite spots. Neil had been to Bristow Prairie a number of times, but he hadn’t been to the small wetlands that—as far as we know at present—are the northernmost outposts of Sierra Nevada blues. He also wasn’t aware of the south-facing bald I call “the rock garden” or “Lewisia Point,” two other excellent places to see butterflies. Our trip was mutually beneficial—I showed him my favorite spots, and he taught me a lot more about identifying butterflies. Read the rest of this entry »

This handsome madrone (Arbutus menziesii) is growing on Rabbitbrush Ridge. It was laden with bright red berries. Beneath it is an unusually colorful, low-growing Oregon white oak (Quercus garryana). In the foreground are the silvery stalks of rubber rabbitbrush (Ericameria nauseosa). The species’ abundance here elicited my name for this steep, rocky ridge.

One goal of my outing was to come home with seeds of the very late-blooming autumn knotweed (Polygonum spergulariiforme). I have a small population on my property that I’m working on expanding. Anything still blooming at the end of October is worth having, no matter how small its flowers.

With the days getting shorter and colder and the damp days increasing (I’m not complaining—after this summer I’m so thankful for wet weather!), I was looking for a dry and, hopefully, sunny day for one last trip into the mountains before winter really sets in. While the sun was playing peek-a-boo behind the clouds all day, at least it was dry on October 31, and I was able to head out to the Rigdon area. I decided to stay at fairly low elevation given the clouds and limited time and headed for Grassy Glade, stopping along the way for anything that looked colorful or interesting. And once I got to Grassy Glade and walked down to the end of the road past the meadow, I had just enough time to head down to “Rabbitbrush Ridge” where the last flowers of rubber rabbitbrush were still in evidence. It was a pleasant if unexciting day—hopefully enough to sustain me until the flowers reappear in February and March. I didn’t expect there would be much to photograph, but as you can see, I found plenty of interesting plants on my end-of-season trip. Read the rest of this entry »

On the way up, we stopped for lunch at the top of the quarry. John’s proximity to the edge of the cliff gave me the willies, so I sat farther back.

On October 16, it was a beautiful clear day, and John Koenig and I headed up into the Calapooyas for one last chance to visit this wonderful area before winter set in. We headed down Road 3810 that runs along the west side of Balm Mountain. In the past, John and I had planned a trip to find a way to hike up to the south end of Balm Mountain (which is really a long ridge) through some meadows we could see on the aerial images. All my previous trips were approached from the north end of the mountain. We tried several times to get down to the end of the road in the past, but trees blocked it well ahead of where we needed to start (see Another Look at Aspen Meadow and Bradley Lake). On a previous visit to what we call Aspen Meadow, a wetland along Road 3810, we had driven down the road and discovered the trees were finally cleared, but there was a huge washout—one that I can’t see ever being fixed—about a half mile from where it used to dead end.

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.

Like many openings in the area, the southernmost one in the complex had Oregon white oaks (Quercus garryana) being crowded out by ponderosa pines (Pinus ponderosa) and other conifers. Enhancing oak habitat has been the main focus of restoration in the area. Hopefully now improving the area for milkweed and monarchs will also be a priority.

Having found purple milkweed (Asclepias cordifolia) and monarchs at Monarch Meadow (see Hidden Meadow Reveals a Thrilling Secret) and at the meadow complex north of there (see A Week of Monarchs and Milkweed: Day 1), the next logical place to check was another complex of openings even farther up the ridge. On July 5, Joe Doerr and I headed up there to investigate. These openings also follow the old road that the middle complex is along, so we felt particularly confident we would find more milkweed. We decided to drive in from the north on an old but (barely) driveable road. I had been on that road several times years ago, to access what Sabine and I call “Gateway Rock Ridge” (see First Outing of the New Year for the most recent trip), but I can’t imagine doing it now. The tire tracks seemed to be sinking down and lots of vegetation was reaching out into the road from the surrounding forest. Thank goodness we were in a Forest Service rig!

Unfortunately, mortality is very high for these tiny monarch caterpillars. Most get picked off by wasps and other predators when they are quite small.

We parked at the top of the old road and saw ground rose (Rosa spithamea) in bloom right by the car. From there we walked south. Before long we came to the first opening, lying right along the ridge. Sticky birdbeak (Cordylanthus tenuis) grew abundantly here along with western rayless fleabane (Erigeron inornatus). These normally uncommon species have been showing up at most of the other milkweed sites, so it was a good sign. There had also evidently been a great display of showy tarweed (Madia elegans), but it was already shriveling up in the heat of the day. We didn’t spot any milkweed at first, but then we started to see it scattered about in several openings. We found monarch caterpillars and eggs as well. Mission accomplished! We walked as far down the road as the uppermost meadow of the middle complex that we’d both already been to on separate trips. So now we knew the area all along the old road and started back toward the car. Read the rest of this entry »
