It was late fall, but still felt like summer when I visited Stebbins in September. Each season has its highlights, and I went to the canyon looking forward to flying insects, active birds, and the early hints of fall colors. I wasn’t disappointed! The Anna’s hummingbirds (Calypte anna) and the grasshoppers were quite lively, and it sometimes took me a minute to register which of the two large flyers had just whizzed past my head.
Poison oak (Toxicodendron diversilobum) is always showy this time of year. I love to see it looking healthy and abundant: it is an important food source for birds, herps, insects and some mammals.
I spent a long time watching a gray hairstreak (Strymon melinus) on slender clover (Trifolium gracilentum). I hadn’t seen one in Stebbins yet – it is a pretty little butterfly!
In June, I had the pleasure of exploring Stebbins along with Miriam Morrill, who has been exploring ways to represent fire conditions, fire and fire effects graphically. I took some notes during our discussion (at the bottom of this post) and then compiled these sketchbook pages based on photos and my notes.
Having walked along the creek trail a few days earlier, I returned to Stebbins to hike up to Blue Ridge. Abundant insect life:
A beautiful view of the full creek:
An iris I had not seen yet at Stebbins:
A very calm and quiet cicada:
My interpretive sign showing how plants and animals use Cold Creek in both wet and dry seasons is up at the reserve!
It is posted at a small creek overlook along the Homestead Trail. I developed the sign to highlight how plants and animals make use of a seasonal stream in both wet and dry times of year. To illustrate the concept, I selected a set of organisms that represent a wide variety of strategies for coping with fluctuations in water availability in different seasons. Given a two-color design constraint, I used the colors to help emphasize the species and the changes in their environment.
Here is the sign alone:
On an overcast day that was comfortably cool, I tried to see as many different areas in the reserve as I could. I headed up the trail towards Blue Ridge first and watched an oak titmouse (Baelophus inornatus) poking around in the dirt at the edge of the trail. There were still bunches of nearly dry California cudweed (Pseudognaphalium californicum), along with the last blooms of coyote brush (Baccharis pilularis).
Tuleyome and the Friends of Stebbins Cold Canyon Reserve have been continuing to stabilize the trail, shoring up the steep sections while the shrubs that ordinarily hold the hillsides in place are regrowing.
The sky was filled with dramatic swaths of clouds, so I took a moment to capture the view back along Highway 128.
Many of the toyons (Heteromeles arbutifolia) that started regrowing immediately after the fire did not produce flowers and berries until this year.
In the overall grey of the day, the fall colors at the reserve stood out sharply:
Because there had been a small amount of rainfall already this fall, the creekbed was damp and there were a few pools in places; enough moisture for mosses to have begun to rehydrate. The view through the culverts that are now the official access route into the canyon is striking and I finally stopped to capture it on this visit.
Here are a few shots of the sketches in progress:
In the morning when the temperature was approaching 90 degrees F, a fairly short walk through the reserve revealed a number of plants I had not seen in previous visits, including green cudweed (Gnaphalium californicum) and narrow-leaved milkweed (Asclepias fascicularis), below. I also observed galls on poison oak, which are made by a gall mite, Aculops rhois.
California fuschia (Epilobium canum) is abundant in the reserve in the summer, but I saw a new Epilobium in the creekbed this visit, denseflower willowherb (Epilobium densiflorum). The puffy, plume-like fruits of pipestem clematis (Clematis lasiantha) were abundant in several places along the creek trail.
Thanks to the wetter winter, there was still water in the creekbed this July, and plenty of plants and animals taking advantage. Red rock skimmers (Paltothemis lineatipes) buzzed me as I stood on rocks above the water, peering into the creek to see freshwater snails that are harder to spot when the water is higher. I fished the head of a Jerusalem cricket (Stenopelmatus sp.) out of the water; I’m sure the rest of its body had been a juicy treat for something.
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.
