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!
Early September brought strong winds, which proved too much for some of the oaks in the reserve that had been weakened by fire. The one below was on the trail just before the actual entrance to the reserve, very near where the new trail access meets the original trailhead at Highway 128.
Although weakened, this oak had been alive before it fell. This is post-fire regrowth:
It’s oak gall season! I spotted the leaf below right in the middle of the trail, with galls from two different wasps. The urchin gall wasp (Antron quercusechinus) makes the spiny pink galls and the crystalline gall wasp (Andricus crystallinus) makes the furry pink galls. These wasps, in the family Cynipidae, lay their eggs in oak leaves (in this case a blue oak), and the eggs secrete plant hormone mimics which cause the leave to form the spectacular gall. The larvae grow and feed in the gall for weeks to years, depending on environmental conditions, and then pupate within the gall and emerge as adults.
Continuing the oak theme, I looked carefully at oak regrowth along Cold Creek. Interior live oak, an evergreen oak, is generally a more vigorous basal sprouter, as observed below:
Blue oaks, which are deciduous, generally do not resprout from their bases, but show regrowth in their crowns:
