Exciting Day at Spring Prairie

On July 25, Nancy Bray and her husband, Herb, invited my husband Jim and me to join them on a trip to Blair Lake and nearby Spring Prairie. It was a bit hazy from fires to the south but otherwise a lovely day. When we got to the intersection of Road 733 that goes up to Spring Prairie, we made a quick decision to go up there first. I was pleased to see the road was in better shape than I remembered (no more trench down the middle of one section) as it had been quite some time since I’d driven up there although I had walked up the trail from Blair Lake last year (see Beargrass Season at Blair Lake).
We drove straight up to the edge of Spring Prairie and parked the car. On getting out, I immediately noticed lots of butterflies flying about in the large, mostly beargrass (Xerophyllum tenax) meadow. Other than some fireweed (Chamerion angustifolium) blooming farther downhill, nothing was in flower. So what were all these butterflies doing here? Growing among the beargrass was quite a bit of lupine (Lupinus sp.) with immature fruits. The butterflies all seemed to be Anna’s blues (Plebejus anna). If you guessed that they use lupines and other legumes as host plants, you’d be right. They appeared to be mating and laying eggs. I started searching the plants carefully. It took only a few minutes to spot the first egg, looking much like a tiny white sea urchin shell after the spines fall off. I’d never seen one before, but I recognized it from the similar hedgerow hairstreak eggs I’d seen a couple of years ago. What a great start to the day! I continued to look for eggs and found quite a few more, laid on stems and pods as well as leaves. Read the rest of this entry »
Aquatics and More Near Lopez Lake
Yellow pond-lilies (Nuphar polysepala) and the narrow leaves of small burreed (Sparganium natans) fill a very shallow pond in the western wetland.
After last week’s trip to Warfield Bog and Hemlock Butte (see previous post), I was interested in checking out some more places in the area. While exploring on Google Earth, I noticed several apparent wetlands in the area near Lopez Lake, just a couple of miles northeast of Hemlock Butte. From the spotty appearance of the lake in the aerial image, it also seemed likely that Lopez Lake had aquatic plants—always a plus for me. All of the areas of interest could be reached off of Road 5884, out Hwy 58 east of Oakridge. I’d been up the first half of this road a couple of times before to hike to Devil’s Garden, an area with a small wetland and a lake at the base of a talus slope, but I’d never been all the way to the end.

Calapooya Report
I’ve been waiting all summer to get back to exploring the Calapooyas, so yesterday I went up Coal Creek Road to Bradley Lake and Loletta Lakes. Most of this is in Douglas County, but it is all on the north side of the Calapooya crest and in the Willamette National Forest (just barely). They really ought to have run the county line along the Calapooya Divide.
Western boneset (Ageratina occidentalis) is a lovely late-blooming composite with a woody base.
I made a couple of quick detours on my way up to check on the Piperias. Youngs Flat Picnic Area was filled with people camping, but luckily they seem to be leaving the woods on the north side alone. The Piperia elongata are still blooming pretty well, although past peak. I also checked the woods across from Mutton Meadow where I’d seen about 30 Piperia plants in the spring. I managed to find 5 flower stalks. Only 2 had any flowers left. I’m pretty sure they’re P. transversa as they looked white with straight spurs. It also makes sense because they start blooming a bit earlier than elongata, so should be farther along than the P. elongata at nearby Youngs Flat.
When John and I went up Coal Creek Rd in early July, the road was a bit of a mess, lots of branches and rocks. Looks like the road has been cleaned up and even graded. I was thrilled about this until I got up to the base of the cliffs where the Epilobium luteum was in full bloom. It looks like they pushed some of the gravel right into the wet ditch and scraped some of the ditch as well. There were slashed branches. There’s still a lot of good habitat, but this is really upsetting. I don’t know what the official status of Epilobium luteum is, but this is probably the biggest population I’ve seen, and there are loads of other pretty things like Claytonia cordifolia in there. I hate to see them buried in dirt. I’m also concerned about messing with the water flow all these plants depend upon.
Pond near Blair Lake
I spent the day at Blair Lake yesterday. I would have said “spent a relaxing day…” but while negotiating what passes for a path around the end of the lake, I discovered I’d lost my hat. I had to duck under and plow through those stinky Ribes bracteosum 3 times instead of once. Aargh. Thankfully, I did find where my hat had gotten knocked off and will be more careful next time I’m in jungle conditions like that.

The flowers were lovely. The Spiraea splendens and Lilium columbianum were outstanding. Most of the meadow was white with Ligusticum. That one is still confusing me. It is not particularly leafy, like the ones that grow on my property or at Lowder, but it seems way too tall to be L. grayii. Closer to the lake, the Pedicularis groenlandica and P. bracteosa made a beautiful combination. There were lots of Platanthera dilatata as well. The many graminoids had me intrigued, so I collected some and hopefully can get more of them figured out this winter. Neither my list nor the old NPSO ones have any graminoids.
