Our theme this year is "Ethnobotany and Dyeing with Plants", with the goal to learn how several indigenous people groups use plants and natural materials to dye fabric or objects. To contain the scope, my research is at the survey level rather than a deep investigation. Our first group was the Tlingit people from Southeast Alaska (see Ethnobotany: Tlingit's and Dyeing with Plants). This time, I'm learning about a people group in the San Francisco Bay Area, the Muwekma Ohlone group (Chochenyo speaking). Their ancestorial territory extended from the Berkeley Hills to Bay Shore, from West Oakland to El Cerrito—covering all of Alameda, Berkeley, Emeryville, El Cerrito, and most of Oakland.
The Ohlone and nearby Coast Miwok people were organized into small, independent societal groups or tribes in the San Francisco Bay Area. They lived off the land, followed sustainable practices to ensure ecological renewal, practiced controlled burns to manage the land, traded, and intermarried. The land provided their needs for community, food and water, shelter, transportation, tools, and art. I chose the Muwekma Ohlone group because we live in the East Bay, which is within their ancestorial territory. The East Bay is a beautiful place. Sometimes I can imagine what the area would have been like before first contact, and it is magnificent!
Ohlone Basketry
The Ohlone are renowned for the art and skill of their basketry. Baskets were an essential tool for daily life. Baskets and woven mats were made in many shapes and sizes, and were frequently decorated or embellished.
Baskets had many functions, such as gathering and storing food, transporting firewood or other heavy loads, catching fish, holding water, cooking, winnowing or sifting grains, gaming, and carrying infants. Although functional, the baskets were also works of art. I found that there are few examples of Muwekma baskets available for viewing, since many have been collected by missions, museums and private collectors around the world. I was able to find some examples on the Muwekma Ohlone Tribe official website and several others.

Note that "Costanoan" is a Spanish word for "coastal". It was used by early explorers to refer to indigenous people living near the water, to distinguish them from those living inland. The term is descriptive and not a tribal name.
Basket Making
Basket material was gathered from nature, and included roots, rhizomes, grasses, reeds, shoots, sprouts, and even leaves. The materials had to be gathered at the right time of year and then processed and kept moist to ensure flexibility. The Muwekma understood plant growth cycles and knew when to harvest and how to harvest sustainably to ensure an ongoing supply. Following are some of the plants that supply basket-making material:
- Common Tule (Scirpus acutus) is woven into loose baskets to collect berries and eggs, and tight baskets to carry water.
- Cattail (Typha latifolia) is used to create mats, rope, and baskets.
- Willow (Salix spp.) shoots are peeled and used for coiled work, and the warp (the long vertical threads that provide strength) of some twined baskets.
- Sedge (Carex mendocinoensis and Carex barberi) rhizomes are used to weave baskets.
- Big leaf maple (Acer macrophyllum) shoots are split for the white element in some baskets.
- Bulrush (Scirpus spp.) is dyed with walnut or mud and used in baskets.
- Bracken fern (Pteridium aquilinum) rhizomes supply two membranes used in basketry.
- Chamise (Adostoma fasciularis) is a chaparral plant used in Ohlone basketry.
- Common horesetail (Equisetum arvense) and Common Scouring rush (Equisetum hyemale) rhizomes are used as a black element in Ohlone basket design.
- Hazel (Corylus cornutta) is a preferred warp material and basket rim material in Ohlone basketry.
- Poison oak (Toxicodendron diversiloba) shoots can be used in basketry.
- Redwood (Sequoia sempervirens) sprouts from burls can be used in basketry.
- Rush (Juncas, Juncus affaris) leaves can be woven into the basket design.

Baskets came in many shapes, sizes and designs. Coil baskets are a common and durable weaving style. A coil of willow shoots is wound tightly with sedge root and then the coil stitched firmly together with a stiff root or reed. The weave can be loose or tight, depending on the basket's use.
Many baskets include a pattern that is woven throughout the three-dimensional shape, which requires the weaver to use sophisticated mathematical and spatial skills to transfer a geometric design from mind to form. The pattern might be developed by weaving in dyed grasses, or by using a different type of root or grass. Different colors and textures were introduced by using a variety of plant materials in the weaving. Patterns were also developed using embellishments such as shells or feathers.
Linda Yamane's demonstration video "Ohlone Basket Weaver - Linda Yamane" provides a quick look at the process of gathering and preparing materials, weaving, and embellishing Muwekma Ohlone baskets. Likewise, did Corrine Pearce's video "Pomo Basket Weaver - Corine Pearce on Pomo Baskets". Pomo territory is also in Northern California but further north near Clear Lake. Many tribes use similar techniques but with cultural variations and adaptations for the materials at hand.
Dye Sources
Original dye sources included plants and materials such as mud and iron. For my own quick reference, the following table provides a summary of some of these dye sources with notes for any additional information. I was surprised to find that the Muwekma often used alternate material to incorporate color, rather than dyeing plant material. For example, weaving in the black stems of the Five-finger fern to add a design in black.
The Ohlone bury basket material, such as tule grasses, in mud to dye it black. Another technique is to harvest roots or shoots that grow in marshland that is heavy in iron, which naturally dyes or colors the plant material black.

Decorative Sources
Unadorned baskets stand on their own for beauty, form and function, relying simply on the materials and the craftsmanship. However, weavers also choose to express themselves or the group's identity with woven patterns and designs. This Ohlone cooking basket is a good example. The striking black pattern is varied and appears on both sides of the basket.

Weavers also decorate their basketry with objects such as shells, feathers, and leaves. This Ohlone basket is from Santa Clara near San Jose and is part of the Smithsonian collection. According to it's description, the basket is embellished with olivella shell disc beads, remnants of red woodpecker feathers and quail topknot feathers on a background of sedge root weft (the horizontal threads).

This contemporary basket was made by Ohlone weaver Linda Yamane. She is on a journey to locate historic Ohlone baskets and to restore Ohlone basket weaving. The basket is decorated with olivella shell disc beads and red feathers. Traditionally red woodpecker feathers would have been used, but feathers from wild birds are typically protected and cannot be harvested. Yamane has improvised by using chicken feathers dyed red and clipped to shape.

Summary
That concludes another brief ethnobotany tour of sources used to create, dye, and decorate the beautiful Muwekma and Ohlone basketry from the San Francisco Bay Area. There is more to learn. I hope to seek out baskets in local museums and collections to see them first hand. While on our Over-the-Hills-Gang hikes in the East Bay Regional Parks, I'll be more attuned to noticing plant sources for basket making in the environment.
I'm curious whether the Regional Parks system has a sanctioned and sustainable process for indigenous people (and perhaps non-indigenous artists) to gather plant material for dyeing or basket weaving. Indigenous peoples used sustainable methods to harvest plant material, which ensured it would not be over-harvested. Perhaps a protocol could be developed for controlled access to plant materials for personal artistic use.
