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 »
