Many of you know Gerry Carr’s fabulous plant photos that he donates to the Oregon Flora Project Gallery, the WTU Image Collection (the Burke Herbarium’s gallery of Washington plants), and posts on his own site, Oregon Flora Image Project. If you don’t, be sure to click on the links! Trying to photograph almost every species in Oregon is a huge undertaking, and I’ve enjoyed helping Gerry find plants in the Western Cascades that he hasn’t photographed yet. Several species still on his to do list grow in the wonderful area of southeastern Lane County that I spend so much time in. It seemed like it might be the right time to find some of those late blooming plants, so on Friday, August 10, I picked Gerry up in Lowell and headed down along Hills Creek Reservoir yet again.
Our first stop was Moon Point. Last year we spent the whole day at Moon Point (see Moon Point Melting Out), so this trip, we were only heading to the upper part of the Youngs Rock trail, which is easier to access from the top. With thousands of plants to photograph, one must be as efficient as possible! On the way to the trail intersection, I went poking around looking for the rare green-flowered ginger (Asarum wagneri), one of Gerry’s targets last year. I was surprised to find several still in bloom and was thrilled to find a couple of ripe seeds. The common long-tailed ginger (A. caudatum) was also still displaying flowers, and I found plenty of ripe seed. I’ve posted scans of the latter in the Seed Gallery or you can click here to see the neat fleshy appendages on the seeds. While I was searching for ginger seeds, Gerry discovered his first target plant of the day, mountain campion (Silene bernardina var. rigidula). This is a rare species I’ve only seen here, at nearby Groundhog Mountain, and at Abbott Butte. Silene species are often called catchfly and, indeed, these are sticky enough to catch insects. We photographed some really nice specimens in the shade just after the split in the trails. It was a good thing we did it then because on our way back they were in the sun and had shriveled up. I’ve noticed this with the fairly common Douglas’ campion (S. douglasii). They seem to look their best on cloudy days or first thing in the morning. Not sure why this is true, but I’m sure there’s a good explanation. Read the rest of this entry »
On Friday, August 3, Molly Juillerat and I will be leading a field trip to Warfield Bog and Hemlock Butte wetlands east of Oakridge (for more info or to sign up, call the Middle Fork Ranger Station at 541-782-2283). To make sure the roads are okay and to see what might be blooming, I went for a scouting trip on Sunday (July 21). On the drive up, I was very pleased to score some ripe seeds of silver lupine (Lupinus albifrons), one of my favorite rock plants for its gorgeous silvery foliage. Lupines are very hard to collect seed from on the fly. Their seed pods explode almost as soon as they are ripe, vaulting the seeds away from the plant. The best way to collect is to put some sort of a bag over the ripening pods to catch the seeds. This is great for a monitored site, but for a random stop along the road, I just had to get lucky. Many of the pods had released their seeds and were all coiled up. Some pods were starting to turn brown but hadn’t opened up yet. I lazily threw them on the seat of the car, planning to put them in a seed envelope later. When I returned to the car to eat lunch after my first foray at Warfield Bog, they had exploded from the heat in the car, I suppose, and had scattered seeds all over the place. A bit of a mess, perhaps, but more seeds than I’ve ever managed to get before, so I was happy. My most recent plant in the garden died after the March snowstorm this spring, so I need to get some more started. Read the rest of this entry »
After much time off, I’m back to writing descriptions for my book and am trying to finish up the arnicas. Arnicas are a difficult bunch to sort out, and I’ve been struggling to gain some understanding of them for a while now. They are variable, can hybridize, and sometimes reproduce by a form of self-sowing called apomixis. Apparently this can lead to populations with different characteristics than the norm. This genus definitely has an independent streak and doesn’t like to follow the rules.
On Tuesday (August 30), I left the Hemlock Lake campground and drove the 18 miles or so east along the ridge to the Whitehorse Meadows trailhead at the northern end of the Rogue-Umpqua Divide. I wondered what might still be in bloom at the relatively high trail at about 5700′. Just a mile or so before the trailhead, I stopped at a favorite spot, a lovely roadside wet slope. It was filled with Parnassia cirrata, Kyhosia bolanderi, Erigeron aliceae, and there were also some lovely leopard lilies (Lilium pardalinum). It looked like things would be great along the trail. Then I noticed some burned trees above the wetland. Hmm. It wasn’t until I came around the corner and saw Black Rock, the prominent feature in this area, completely surrounded by dead trees, that I realized what had happened. What a shock! One of my favorite trails utterly devastated. The trail meanders slowly downhill over 3 miles to the large Whitehorse Meadows. Until just before the Whitehorse Meadows, almost no trees had survived this fire except a few in the many small patches of meadows, outcrops, and wetlands along the way. How did I not know this area had burned? It wasn’t until I got home and called the Diamond Lake Ranger District office of the Umpqua National Forest that I found out it burned in the fall of 2009, just a couple of months after my last visit here. The fire was named after Rainbow Creek, a tributary of Black Creek that starts nearby. It burned over 6,000 acres. It occurred around the same time as the Tumblebug Fire, which was much closer to me and kept me away from southern Oregon entirely. For a dramatic aerial photo of the fires, see Earth Snapshot.

I just can’t stay away from the Calapooya Mountains. There are so many interesting rocky areas and wetlands, and I want to see them all. So yesterday (September 4), I headed back along my usual route up Coal Creek Road 2133, but this time I went all the way past Bradley Lake to the end of Road 5451 where it deadends at the south trailhead for Bristow Prairie. When John Koenig and I went to Loletta Peak and Bradley Lake back in July (see Mystery Bedstraw Blooming in Calapooyas), we took a quick spin down the road at the very end of the day. Seeing another cliff and talus slope and several meadow and wetland areas, we decided it was definitely worth a return trip. Exploring this area was my main goal yesterday.
The road to Bradley Lake is in fine shape except for one spot that is very wavy from being washed out. It is no problem as long as you drive really slowly. There is a nice rocky spot here with loads of Erigeron cascadensis (in seed right now). Going so slow, I noticed a patch of rayless yellow composites and pulled over. It was Arnica discoidea still in good bloom. Neither rayless arnica is common in the Western Cascades, but this one I’ve only seen a few times, so I was very pleased. After photographing it for a while, I poked around the roadside outcrop and small talus slope. I heard but did not see a pika, but I was able to watch several golden-mantled ground squirrels. It must be the time of year when the babies get curious because it seemed that several of them were pretty young and running around quite a bit. An adult was busy trying to get some of the red elderberries on a large shrub growing out of the rock. At one point, when I wasn’t looking, I heard a crash of sorts. It appeared as though he or she had slipped off the branch. It was quite amusing watching all this activity. Read the rest of this entry »
Yesterday (August 21), I sort of took the day off from exploring the Western Cascades to join Gerry Carr, Dick Halse, Stu Garrett, and Barbara Ertter for a trip up to Fuji Mountain. Barbara is a Potentilla expert from the Jepson Herbarium who lives in Idaho, and she wanted to see the rare Potentilla up there. While Fuji is a High Cascade peak, the upper trailhead is accessed from the same road as Hells Half Acre. I wanted to show everyone the interesting old quarry spot along Eagle Creek Road 5883 that Sabine and I had discovered after our last trip to Fuji Mountain in 2007 (see Unusual Botanical Spot on Eagle Creek Road), just up from the Hells Half Acre trailhead, so after our successful hike to Fuji, we made a stop on the way back. The Ageratina occidentalis was coming into bloom and the lovely Parnassia cirrata was just starting to open. The green-flowered alumroot (Heuchera chlorantha), so abundant along the road, was just about finished. I was also able to show Dick Halse, an expert with our rockcress, an Arabis/Boechera that I’d seen there before. Alas, it was too over the hill for him to identify. Read the rest of this entry »
