Thinking About Climate Change at Youngs Rock

The north side of Youngs Rock is hard to get close to. Although there’s no talus, the slope is still quite steep and slippery, and the rock outcrops are not all stable. It reminds me of a Japanese garden. With binoculars, I could see lots of blooming Oregon fawn-lilies and a single cliff paintbrush, but I didn’t feel comfortable trying to get close to them like I did when I first started coming here.

The south side of the rock is really craggy and supports many interesting plants in its cracks. It’s open but also really hard to get up close to because of the slippery and steep talus at its base. Better have binoculars!

On May 26, Lauren Meyer and I spent a beautiful day hiking up to Youngs Rock. It was sunny but only in the low 70s—pretty much perfect. In my work for the Flora of Oregon, I had just read through a draft copy of a chapter on climate change that will be part of the third and final volume of the flora. I couldn’t help but look at what we saw along the trail through the lens of climate change. We discussed it quite a bit as well. The Youngs Rock trail follows a south-facing ridge in the Rigdon area of southeastern Lane County. We hiked the middle stretch—my favorite part through a string of meadows—from about 3100′ to Youngs Rock itself, an impressive pillar rock, at about 4500′. There are a number of plants here that are near the most northerly edge of their range. These include whisker brush (Leptosiphon ciliatus), ground rose (Rosa spithamea), birdbeak (Cordylanthus sp., I’m still unsure how to distinguish the species), and many-stemmed sedge (Carex multicaulis). I’d only discovered the latter a couple of years ago (see Back to Lower Meadows of Youngs Rock) and was surprised at how much more there was along the lower stretches of the trail. I’ll admit I don’t spend much time on graminoids, and this sedge looks more like a rush (Juncus spp.) than a sedge. Farther up the trail, where we didn’t go on this trip, is the most northerly site (so far) for galium broomrape (Aphyllon epigalium). With the caveat that I’m not a scientist, I would think these meadows might adapt to climate change fairly well and could even become home to more species adapted to the hotter regions to the south, though I suspect  blooming periods might move up.

Eagles Rest Flowers Through the Summer

Looking down through ookow (Dichelostemma congestum) and tomcat clover (Trifolium willdenovii) at a sweep of Oregon sunshine (Eriphyllum lanatum) on the lowest cliff, June 4.

Menzies’ larkspur (Delphinium menziesii) and Oregon sunshine (Eriophyllum lanatum) on the west end of the ridge, June 18.

I mentioned in my earlier post about a trip to Eagles Rest in May (see Unusual Plants of Eagles Rest) that I was picking up farm-fresh vegetables almost every week in Dexter this summer. Because it was only about 8 more miles to Eagles Rest, the short trip up to the summit became part of my weekly ritual. I headed up there eight times altogether this spring and summer.  A great many species I was looking to add to the restoration area on my property grow there, so I was able to watch the flowering and collect seed of all of them as the season progressed. I love that this site is so short a hike and short a drive that I can be there in back in just a few hours, if that’s all the time I had, although when I was collecting seed, it sometimes took much longer than that. Here is a look back at the flowers I saw on my trips to Eagles Rest in June and July. Read the rest of this entry »

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 »

A Week of Monarchs and Milkweed: Day 2

Two monarch caterpillars sharing the same purple milkweed plant.

Nancy Bray and I had been planning a trip to the North Umpqua for quite a while. I was rather torn between going to some of my favorite places in Douglas County and looking for more milkweed and monarch sites. As luck would have it, I was able to do both. While checking the distribution of purple milkweed (Asclepias cordifolia) on the Oregon Flora Project Atlas, I had noticed one record of milkweed on Medicine Creek Road 4775 in the North Umpqua area from 1994. While out with Crystal Shepherd on Monday, she told me she used to work at the Diamond Lake District and had seen the milkweed at that site just 5 years ago. Read the rest of this entry »

Forensic Botany at Tire Mountain

View of Oakridge and Hills Creek Reservoir. You can see the dirty air sitting down low in valleys and obscuring the reservoir. A glimpse of a small forest of oaks can be seen a little left of the trees in the center at what appears to be the base of the meadow.

Rain at last—what a relief! Not that I wasn’t enjoying the glorious weather we’ve had lately, but things were getting bone dry, the air was dirty, and the roads were terribly dusty (as is my car both outside and in!). On Thursday (October 11—10/11/12 for those of us who love numbers), I went to Tire Mountain to enjoy the weather before the promised rain. It was dry—really dry. It is normal this time of year, especially at that elevation (under 4000′), for most of the meadow plants to be dried out and the woodland plants to be yellowing, but after so many weeks of drought, even the sword ferns—arguably one of our toughest plants—were badly wilted. I’ve been to Tire Mountain in the fall in the past and marveled at the abundance of tiny green seedlings covering the ground. These will be many of the annuals that will put on a show the following spring. Without a drop of water to set them off, the seeds are still dormant in the soil this year. How long it will take for them to germinate now that the rains have started? It might be worth a return trip soon to find out. Read the rest of this entry »
