Mountain Plants of the Western Cascades

Posts Tagged ‘Bristow Prairie’

I was impressed that the whole group was willing to climb down the rocky ridge I call “Lewisia Point” to see one of the few populations of Columbia lewisia south of the Columbia River Gorge area. The lewisia is growing in the rocks by some low-growing serviceberry (Amelanchier alnifolia). Click on the photo to blow it up to see the lewisia’s delicate pink flowers.

For years, I have been planning to lead a trip up to Bristow Prairie for the Emerald Chapter of the Native Plant Society of Oregon. I always ended up having other commitments or others were leading trips around the same time. But, at long last, there were no conflicts, and on Saturday, June 25, Jenny Moore, Middle Fork district botanist, and I brought a group up to Bristow Prairie. It was a very hot day in the valley, and I was surprised at how hot it was even at over 5000′, but I’d already planned a fairly tame exploration of some of the highlights of the diverse area, so I thought it was doable in the 80° heat. We followed the same route I’d taken for a prehike on Monday, June 20, the first day of nice weather after I’d heard from Chad Sageser that the snow had melted and that he’d cleared the last of the trees off the road (thanks again, Chad!). The plan was to go to “Lewisia Point” first to see the rare Columbia lewisia (Lewisia columbiana) and the nearby shaley area, which has a number of annuals that like the moisture that remains there after the snow melts. Then back to the meadow to make a loop over to the rock garden, across the meadow to the lake and surrounding wetland, and then back to the road. Read the rest of this entry »

With the number of times I’ve been to Bristow Prairie (this was my 26th time), I don’t remember ever seeing the prairie so pink with fireweed (Chamerion angustifolium). Molly said the Forest Service had done a controlled burn on the prairie not so long ago, so that would explain it.

On July 18, Molly Juillerat (and Loki) and Nancy Bray joined me for a day at Bristow Prairie. We decided to skip the trail to make sure we had time for the lake, so we parked by the edge of the main prairie. Our first destination was the rock garden since we knew it would be hotter on the rocks later in the day. June and early July’s heat and drought had dried it out earlier than usual, but I was able to collect some seed. From there, we headed over to the lake and surrounding wetland. Going through what is by late July really tall foliage is tricky because you can’t see the ground and any possible mountain beaver holes. But we took our time and enjoyed looking for butterflies and other insects on the way down. Naturally, the area was much moister than and still had many flowers in bloom, but it was dry enough to walk around the wetland without rubber boots. I don’t get down to the lake often enough, so I’m glad we were able to spend some time there. Read the rest of this entry »

While the rock garden area wasn’t quite as floriferous as usual, the east end had a lovely display of Menzies’ larkspur (Delphinium menziesii), and there were barestem lomatium in bloom everywhere.

On June 4, John Koenig and I went to Bristow Prairie in the Calapooyas. It was our first trip of the year here, but we’re planning to show this area to some folks from the Burke Herbarium in Washington in a few weeks, so we’ll be back soon.

We started our day by hiking the trail from the north trailhead (once we found it—the trail sign is now smashed under a fallen tree!). We were hoping to catch the early flowers, and there were still a few patches of snow in the road ditch, but the warm dry spring had already moved the rock garden area along. There were no exciting discoveries this trip, and there were surprisingly few butterflies or other insects for such a sunny day, but I thought I’d share some photos. Read the rest of this entry »

The wetland by the lake was filled with bistort (Bistorta bistortoides), Oregon checkermallow (Sidalcea oregana), and arrowleaf groundsel (Senecio triangularis). We hadn’t had time to explore this area last trip, but I like to come down here at least once a year. There are too many wonderful spots at Bristow Prairie to see them all on a single trip.

Follicles of Menzies’ larkspur still filled with seeds. Usually when an animal brushes by the plant, the seeds get flung out of the capsules. More than once, I inadvertently kicked a plant as I reached forward to grab the seeds, knocking them out before I could get any. Plants have so many clever ways of distributing their seeds.

After the terrific trip John Koenig and I had to Bristow Prairie earlier in the month (see Still More Discoveries at Bristow Prairie), I decided to return on July 15 to see the next wave of flowers. This trip was not nearly as pleasant as the first because most of the afternoon I was hounded by biting flies. Some looked to be deer flies; others were both larger and smaller, but they were all determined to drive me crazy. At the very end of the day, some house fly-sized ones were actually leaving what looked like bruises on my arms just minutes after they bit me. Luckily they didn’t itch for all that long. I’ve never experienced that before in the Western Cascades, so it was doubly disconcerting. Biting flies were one of the many things I disliked about my short tenure living in the Midwest.

The rock garden is always gorgeous in June and July. The cream-colored hotrock penstemon (Penstemon deustus) was at peak. It was joined by frosted paintbrush (Castilleja pruinosa), Oregon sunshine (Eriophyllum lanatum), bluefield gilia (Gilia capitata), and much more.

On July 3rd, John Koenig and I went to Bristow Prairie, one of our favorite places. Due to the pandemic, we drove up separately. Turns out we were both planning to go, so we figured we might as well go at the same time. Two sets of eyes are much better for finding interesting things. And we always seem to find unusual plants and other cool things up in this wonderful area.

From the rocky viewpoint at the end of the trail, we had a great view to the south of the east-west-oriented Calapooya Mountains, including Bristow Prairie where we were the day before and Balm Mountain where I went 10 days later. The coppery-colored shrub to the right is actually a very dwarf Pacific yew (Taxus brevifolia), while some snowbrush (Ceanothus velutinus) is blooming to the left.

I believe this is the caterpillar of the police car moth. Its host food plants are in Boraginaceae like this blue stickseed (Hackelia micrantha). He’s clearly been eating both the leaves and the inflorescence.

After our Bristow Prairie trip (see previous post), Betsy Becker decided to stay in the area another day, so on Sunday, June 23, I brought her up to the Moon Point trail. We had a mostly relaxing day (Betsy was not so relaxed when I persuaded her to sit on top of the cliff at the end of the otherwise easy walk!). It was a beautiful day, and the flowers were still fresh. We saw some more plants she wasn’t familiar with, including the rare green-flowered wild ginger (Asarum wagneri). We also made a loop through the lower meadows to pretty Moon Lake. Here are some photos. Read the rest of this entry »

Kris checking the Lewisia key on her tablet while Betsy continues to count plants.

Betsy spotted this pair of three-leaved plants trying to trick a trio of botanists. The Columbia windflower (Anemone deltoidea) flower is trying on the western trillium (Trillium ovatum) leaves, perhaps disappointed that its similar leaves (hiding above) are much smaller.

Citizen’s Rare Plant Watch is a citizen science program that was started by the Native Plant Society of Oregon in 2012 and is now run by the Rae Selling Berry Seed Bank and Plant Conservation Program at Portland State University. Volunteers, led by Kris Freitag, travel around the state gathering information on rare plants and trying to relocate plants that have not been seen in the state in many years.

Kris contacted me a while back about monitoring the Columbia lewisia (Lewisia columbiana) John Koenig and I found last year (see Yet Another Exciting Discovery at Bristow Prairie). I suggested I join her and give her the “tour” of one of my favorite places. After several volunteers had to cancel, only Betsy Becker was able to make it all the way down from the Portland area. As it happened, Walama Restoration was hosting a campout at Sacandaga Campground that weekend, so Kris and Betsy and I joined them there on Friday night and headed up to Bristow Prairie on Saturday morning, June 22nd.

An unusual “pink-eyed Mary” (Collinsia grandiflora)!

So far, my botany season has been spent checking out lower elevation meadows in the Cascades. But finally, on June 4, it seemed like it was time to head up to the higher elevation sites. The Middle Fork District office told me that the day before they’d gotten a truck through Road 5850, which rides the ridge near Bristow Prairie, although there was a little bit of snow still along the side of the road. They weren’t sure about the upper part of Road 2125 where it comes into 5850, but I figured if the rest was clear, that part would be too. Thankfully it was, as I really wanted to see the early flowers at Bristow Prairie.

I saw a sawfly (sounds like a nursery rhyme or riddle: “I thought I saw a sawfly fly”) for the first time on Eagles Rock a few weeks ago (photo on right) and found another on this trip in the rock garden area (left). Actually, they are not flies (order Diptera) but are in the same order (Hymenoptera) as bees and wasps, and they fly with their legs hanging down the way wasps do. This one looks like the genus Trichiosoma. Although they are large and look rather intimidating, they don’t sting.

A lilac-bordered copper, a snowberry checkerspot, and a pair of mating Hoffman’s checkerspots all sharing the same leafy fleabane (Erigeron foliosus)

I was so excited about finding Columbia lewisia (Lewisia columbiana) at Bristow Prairie (see previous post) that I contacted Molly Juillerat right away. Although she is now the deputy ranger for the Middle Fork Ranger District, her old post as district botanist hasn’t been filled yet, so she’s still the main botanist and the one other local person I know who has been to all the other lewisia sites in the district. I was thrilled that she was able to arrange her schedule to see the lewisia that same weekend, on June 30th. I wanted to get back quickly before the plants finished blooming and became hard to spot again. Read the rest of this entry »

Acres of bistort in the wetland by the lake

We always make a stop along the road to see the tiny least moonworts (Botrychium simplex). There were hundreds of them, some only a half-inch tall. Happily, the population seems to be increasing.

John Koenig was disappointed he wasn’t able to join us for the trip to Bristow Prairie (see previous post) and was still hankering to go there. And I hadn’t managed to get to the lake to look for Sierra Nevada blues on either of my earlier trips, so I was quite willing to return to this wonderful area just a few days later, on June 25th. We started out by hiking down to the lake. I had made sure to put my rubber boots in my vehicle, but I had forgotten to transfer them to John’s truck, so I had to walk very carefully through the still fairly damp wetland surrounding the lake. It was quite beautiful, filled with bistort (Bistorta bistortoides), the Sierra Nevada blue’s favorite nectar plant, and we saw a great many butterflies, including a swallowtail nectaring solely on the gorgeous white bog orchids (Platanthera dilatata) and many checkerspots. But where were the Sierra Nevada blues? We both looked at every blue we saw, but although there were many greenish blues and a few other species, I only saw one butterfly that I believe was a Sierra Nevada blue, but it was so low in the foliage, I couldn’t get a very good look at its underside to be sure.
