Ethnographic Information on
Seasonal Plant and Animal Resource Use
The earliest published mention of plant use by the Clear Lake people was written by
Stephen Powers (1877:206) who states:

    "In the spring, when the wild clover is lush and full of blossoms and they [Clear
    Lake Pomo] are eating it to satiety after the famine of winter..."

This table identifies each writer by letter who mentioned the use or collection of a
plant or animal resource during a specific month or season.  Even though a
particular resource might be mentioned repeatedly in one document, it is listed in
the table only once.

Pomo Resource Use
History and Prehistory of Lake County
and Beyond
The graph below is a composite of many of the resources listed in the ethnographic
accounts.  The lines represent the seasonality of Upland resources (away from Clear
Lake) as opposed to those available in the Lowland (lakeshore area) as listed by
ethnographic reports.  

Resources which could be found in equal quantities in both Upland and Lowland
environments were not used in the graph.   Upland resources included, buckeye,
laurel, grape, manzanita, pine nuts and deer.  Lowland resources included willow,
tule, nettle, tobacco, gooseberry, blackberry, clams, fish and ducks.

There appears to be a clear difference in the seasonal availability of Upland resources
as opposed to those in the Lowlands.  The question is, were the upland resources
important enough to the overall economy to pull people away from the resource-rich
lakeshore for part of the year?

Clovers are mentioned by several of the ethnographers who have worked with the
Pomo (Lewis 1935; Kniffen 1939; McLendon 1977; Loeb 1926).  When trying to
discover the species being referred to, it was found that "clover" was a term used by
the Indians when referring to several different varieties of edible greens collected in
the spring and early summer.  Brown and Andrews (1969) listed 6 plants which came
under the generic category of "Clovers."   Unless otherwise indicated, all were eaten
as greens.

Miners Lettuce (Montia perfoliata) Annual, moist shaded areas below 5,000 ft.

Cowparsnip (Heracleum lanatum) Perennial, moist shaded areas below 9,000 ft.

Lupins (Lupinus densiflorus) Annual, open fields and hillsides below 2,000 ft.

Hedge mustard (Sisymbrium officinale) Annual, below 5,000 ft. April-July.

Goosefoots (Chenopodium spp.) Annual, June-October.

Angelica greens (Angelica tomentosa) Moist and shaded areas below 7,000 ft.  
June-August. Young shoots eaten and taste like asparagus.  Roots considered to have
spiritual protective powers.

Fireweed (Epilobium spp.) Perennial, July-September.

Dandelion (Taraxacum spp.) Perennial, May-July.

Tule (Scirpus spp.) Perennial, below 4,000 ft. June-July.  Base of young shoot pealed
and eaten raw, root eaten.

Clover (Trifolium spp.) Annual, below 2,000 ft. March-June.

In most cases, the young green tops were collected and eaten.
Non-food Plant Use

In addition to the food plants, several of the writers listed non-food plant resources
which were used for ceremonial purposes and the manufacture of tools, shelter,
baskets, etc. (Barrett 1908; Lewis 1935; McLendon 1977; Loeb 1926; Allen 1972;
Purdy 1900; Kroeber 1925).

Tule (Scirpus various spp.) Probably the most widely used plant.  Used for the making
of houses, boats, clothing, basketry, mats, etc.

Willow (Salix argyrophylla) probably the second-most widely utilized plant.  Used for
basketry foundation material, house construction, non-backed bows, leaves are
mashed and mixed with charcoal to make paint and stain.

Soaproot (Chlorogalum pomeridianum) Juice from baked root used as a base for
mixing body paint and stains; ground bulb was placed in still pool of water to stupefy
fish;  hairy outer covering used for brushes.

Wild Violet (Viola spp.) Juice of violet mixed with soot and water to make tattooing

Alder (Alnus rhombifolia) Wood used for a variety of musical instruments (clapper
sticks, whistles, etc.) and gaming sticks.

Wild Grape (Vitis californica) Stem split and used in tying and binding.

Milkweed (Asclepias speciosa) Stem fibers used for twine.

Nettle (Urtica gracilis) Stem fibers used for twine.

Redbud (Cercis occidentalis) Strips of bark used in basketry and whole stems used for
large twined baskets and traps.

Sedge (Carex lanuginosa, mendocinoensis) Roots stripped, split and used as main
basketry twining and coiling material.

Wild Nutmeg (Torreya californica) Wood used for making sinew backed bows.
Oaks and Other Nut Bearing Trees

Probably the most widely published and perhaps the most important plant resource of
the Clear Lake Pomo was the acorn.  As with "Clovers," the oaks of the Clear Lake
Basin were mentioned in early publications:

    "The valleys are usually free from brush and, like a portion of the hills, are
    studded with fine oaks, growing as a rule, at distances of one to two hundred
    feet from one another and often as picturesquely disposed as if set out by a
    skillful landscape gardener." (Becker 1888 as listed in Kniffen 1939:355)

As important as acorns were, it was interesting to note that only Barrett (1908) and
McLendon (1977) distinguished between the many varieties of oak and made note of
the use of their respective seeds.  

Valley Oak (Quercus lobata) Valleys and slopes below 2,000 ft.  Known for good
tasting acorns. These acorns were used for acorn bread (McLendon 1977).

California Black Oak (Q. keloggii) Hills and mountains 1,000-8,000 ft.  Acorns from
this tree were used for acorn mush, tall trunks used for poles and beams in lodge
construction (Barrett 1908).

Pacific Post Oak/Oregon Oak (Q. garryana) Wooded slopes 1,000-5,000 ft.

Tan Bark Oak (Lithocarpus densiflora) wooded slopes below 4,500 ft.

Maul Oak/Canyon Oak (Q. chrysolepis) In canyons and on moist slopes below 6,500 ft.

Buckeye (Aesculus californica) Dry slopes and canyons below 4,000 ft.  Fruit
collected, ground, leached, then eaten.

California Laurel "Pepperwood" (Umbellularia californica) Canyons and Valleys below
5,000 ft.  Seeds collected, outer "fleshy" part eaten, nuts ground, heated and made
into small cakes, used as pepper-like condiment.

Digger Pine (Pinis sabiniana) Dry slopes and ridges below 4,500 ft.  Nuts collected,
roasted, eaten.

Sugar Pine (Pinis lambertiana) Forested areas 2,500-9,000 ft. Nuts collected, roasted,

There were two mentions of Hazelnut (Corylus californica) and Madrone (Arbutus
menziesii) in the literature but their use was not specified (Barrett 1908, Loeb 1926).

A whole range of berries were mentioned in several of the publications but none gave
species names.  Where possible, we have tracked them down.

Manzanita (Arctostaphylos spp.) Brushy or wooded slopes 2,000-4,200 ft.  Berries
eaten fresh or mixed with water to make drink.
