March Visit (3/5/2020)

At the beginning of March I set off to hike the full loop up to Blue Ridge, down the spine of the ridge, past the homestead and back along the creek trail. It is only a five mile hike, but one that I generally do not have time to do given that I stop to draw to frequently. Blissfully ignorant of the new reality that was about to descend on all of us, I marveled at the opportunity to get the full perspective of high and low habitats at the Reserve.

I started by trying something new: marking the spots where I stopped to draw and noting the thing that had caught my attention there. (I drew the map in advance and added the cartoons of the flowers after the fact.)

I was extremely pleased to find California pipevine in bloom! Last year, I caught the flowers once they had dried out, so was determined to find them fresh this year. They look so stunning when backlit with the light glowing through their hollow, yellowy-green bodies veined in red.

Variable checkerspot caterpillars were plentiful on the ridge. I originally misidentified the first one I saw, but realized my mistake when I came on a crowd of them feeding on woolly paintbrush, one of their main host plants.

Two of my favorite tiny wildflowers—purple sanicle and miniature lupine—were growing in bright exposed areas along a steeper part of the trail.

An anise swallowtail (originally misidentified in the drawing) held still long enough for me to do a careful drawing. The grey hairstreak was not so patient, so I drew it based on memory as it flitted from twig to twig.

This is the first year I’ve seen fruits on the manzanitas that were burned!

So many beautiful colors on the hike: so hard to remember to keep moving and not try to draw every single new flower I see.

The effects of our extremely dry February were abundantly evident in the creek, which was incredibly low and filled with algae. It was completely dry near the entrance to the Reserve.

Now that I know that this was my last visit for a long time, with Stebbins closed to support the shelter-in-place rules, I am so grateful for this wonderful gift of a hike.

September Visit (9/26/2019)

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!

March Visit (3/19/2019)

I had two goals on this visit to the Reserve: to conduct my usual observations and to finalize the locations where I planned to have my field sketching workshop participants stop for our six drawing exercises. I didn’t get to the Reserve until around noon, when everything had warmed up into the sixties. With the bright sun, there were butterflies absolutely everywhere! Plenty of wildflowers, too, including California pipevine (Aristolochia californica), which I had not managed to find in bloom in previous years.

November Visit (11/30/2016)

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.

October Visit (10/31/2016)

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.
