Saturday 10/12 started with a relaxed morning in a meadow below the second burn site, West Sims. John Muir Laws and Laurie Wigham engaged three local children in some nature journaling exercises and Miriam Morrill showed us some examples of how she captures her fire observations visually.
Frank Lake, Research Ecologist with the US Forest Service and member of the Karuk Tribe, is a multi-talented scientist and artist. He generously showed us a variety of cultural objects using plants managed with fire, including some of the tribal regalia and other artwork he has himself made.
Frank then accompanied us to the West Sims site so that we could observe some of the day’s burning up close. The terrain at this site was steeper than the day before, and overgrown with blackberry, so we observed some different techniques for starting and managing the fire.
We watched a few large trees go up in showers of spark and flame.
We watched the progress of the burn from above using a drone, and learned a little about fire investigation techniques.
Toward the end of the afternoon, we moved to a site below the area being burned for a different perspective. Frank talked more about how fire keeps the forest healthy, and demonstrated healthy vs. infested acorns. Fire helps control oak moth infestations in tanoak.
Our last evening in Orleans was a community event where we were fortunate to hear talks by Elizabeth Azus and Margo Robbins about basketry plants and fire; Frank Lake about fire and forest health; and Lenya Quinn-Davidson about the movement for community involvement in fire. We nature journalers also presented our work from the weekend and had an opportunity to share our sketches with the community and with the all of the participants in the TREX.
I found this entire experience deeply moving and enlightening; it gave me so much better an understanding of the work of fire in the landscape and what that looks like up close. I can’t wait to see how we develop this project further!
A hot and dry August day: first I noticed that heavy stillness particular to the very hot days of California summer, and then started paying attention to all of the active insects. Grasshoppers took off in all directions to escape as I walked along the trail and butterflies of all sizes were abundant.
One of the few flowers blooming, twiggy wreath plant (Stephanomeria virgata), attracted quite a few bees, both western honey bees (Apis mellifera) and a bumblebee, the black-tailed bumblebee (Bombus melanopygus edwardsii).
One grasshopper stayed still long enough for me to draw it. It slowly dawned on me that there was a reason it was less willing to fly away as I approached: it was missing its right hind leg. It was still able to fly, but taking off clearly took more effort.
A daytime moon over Blue Ridge:
I watched a Sonoma chipmunk (Tamias sonomae) working busily in the trees some distance away. The image below was drawn from a reference photo.
John De Benedictis, a Research Fellow at the Richard M. Bohart Museum of Entomology, has been collecting moths twice a month at dusk in Cold Canyon since 1989. I accompanied him for the first part of his visit on May 18. John sets up a sheet across the path at the entrance to the Reserve, and sometimes a second sheet parallel to the path (and perpendicular to the first sheet), when accompanied by Greg Kareofelas, a Research Affiliate at the Bohart Museum. John hangs a fluorescent light against the sheet, which transmits unfiltered UV light, a mixture of UV and white light.
John collects the moths that land on the sheet for later identification. John started his work in Cold Canyon three years after the last major wildfire and is watching closely to see how moth populations respond after the Wragg Fire. May is the month in which he has recorded the most moth species over the years; on a good night, he collects about a third of the species known to fly at that time of year. The numbers collected this May will be a good indication of how depleted the populations are after the fire.
When John first started collecting in 1989, not long after the previous fire at the Reserve, he observed that Sparganothis senecionana was numerous. S. senecionana is a tortricid that prefers to feed on low-growing plants. Over time, as fire recovery progressed, the numbers of S. senecionana decreased, while those of Archips argyrospila, the fruit tree leafroller (also Tortricidae), increased. A. argryrospila feeds on a number of plants including oaks, but seems more abundant in areas with oaks, and their numbers seem to have followed oak regrowth in the Reserve. This pattern now appears to be repeating after the Wragg Fire: John has observed that Archips numbers are considerable lower since the fire, along with the numbers of other oak-associated moths, indicating that they have been hard-hit by the fire and the loss of oaks.
