Enjoying the wildflowers on a beautiful February day, I also noticed a different form of California buckeye (Aesculus californica) regrowth than I had seen last year. Along the creek trail, some buckeyes that had not regrown in their crowns last year were sending up basal shoots. I love the way the leaf buds look.
I was excited to see a checker-lily (Fritillaria affinis), something I did not catch last year. Greater bee-flies (Bombylius major) were everywhere, enjoying the sun and the flowers.
A yellowjacket (Vespula sp.) resting on purple nightshade (Solanum xanti), a western fence lizard (Sceloporus occidentalis) paused on a rock in the sun, and the first blooms on fleshy lupine (Lupinus succulentus):
A few more blooms (canyon delphinium, blue dicks, and miner’s lettuce):
I’m still working on capturing the grey expanses of dead tree and shrub branches against the hillsides.
Cold creek is beautiful and clear.
The wet winter has led to movement on the hillsides, although maybe not as much as there might have been, given how recent the fire was. This was a slump right along the creek trail.
In November, on a cool but not cold day, I hiked to the top of Blue Ridge. Looking out at Lake Berryessa, it was easy to see part of the area burned by the Cold Fire last summer.
On the way up the trail, I looked for mushrooms enjoying the damp left by rains earlier in the month, and observed regrowth of mountain mahogany (Cercocarpus betuloides), blue oaks (Quercus douglasii), and chamise (Adenostoma fasciculatum). The leaves of yerba santa (Eriodictyon californicum) along the trail were losing their waxy coating. The waxy coating, presumably beneficial in retaining water during dry months, is resinous and highly flammable. Yerba santa seeds may require fire to germinate and can also resprout from rhizomes following fire.
Hillsides stripped of their erosion-controlling vegetation by the fire have been shored up with erosion matting installed by Tuleyome and Friends of Stebbins Cold Canyon Reserve.
Looking across Cold Canyon I was struck by the “rivers” of dead tree branches running down the canyons of Pleasants Ridge. They made a ghostly grey against the greens of new growth and the hills still mostly yellow from the summer.
A few mid-action photos:
Anadromous fish do not make their way into Cold Creek, but Cold Creek is a tributary to Putah Creek, which does have salmon and steelhead. Water quality in Cold Creek (including impacts from fire) has a direct impact on water in Putah Creek and on the organisms that rely on Putah Creek. Chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (Oncorhynchus mykiss) return to Putah Creek to spawn after spending several years in the ocean, and are dependent on cool, clear water free of contaminants for their survival.
In November, I watched Chinook salmon traveling up Putah Creek in downtown Winters, just under the old railroad bridge. I made some sketches onsite:
And then developed a more detailed depiction of the scene at home:
On a cool gray day, I thought that a scrub jay (Aphelocoma californica) in a gray pine (Pinus sabiniana) made a beautiful silhouette against the sky.
A number of spotted towhees (Pipilo maculatus) were foraging in the smaller trees along the trail. I caught one on a perch next to some stairs, and then drew a close-up from a photo.
All over the canyon, poison oak (Toxicodendron diversilobum) in its fall colors glowed vividly against the green and gray of the day.
Mountain mahogany (Cercocarpus betuloides) resprouting. I love the shape of their leaves.
Female coyotebrush (Baccharis pilularis) flowers, and a view of coyotebrush resprouting.
Having established a pattern of drawing the view at the trailhead every six months, I am posting the drawing for September 2016, just a over a year after the fire. Although plenty of charred tree and shrub branches are still in evidence, new growth in tree crowns and from the bases of both trees and shrubs stands out starkly against the summer-yellowed hillsides.
