INTRODUCTION
Phenology is the study of the seasonal timing of life cycle events (Rathcke and Lacey 1985) of organisms. In temperate
regions seasonal development is relatively predictable, occurring primarily in response to accumulated heat, and
photoperiod. Since phenological events generally occur in a reliable sequence, the occurrence of one event indicating
the imminence of another, phenology can be used to time resource related activities. Aboriginal peoples have long
recognized these phenological indicators and Traditional Phenological Knowledge (TPK) is evident throughout Traditional
Ecological Knowledge and Wisdom (TEKW). In this paper we assess the nature and significance of TPK in British Columbia
and the neighboring areas. A survey of the ethnographic literature for British Columbia, Canada and surrounding areas
revealed over 140 examples of traditional phenological indicators. This TPK, representing more than 20 linguistic
groups, is used to indicate the timing of plant and animal resource availability and abundance, to assess and predict
changes in weather and the seasons, and to mark points in peoples' seasonal rounds. Approximately half of these are
direct indicators involving the phenology of one species, typically a flowering plant, to signal the onset of a
prominent stage in the life cycle (phenophase) of a second species, typically an important resource. The rest are less
direct, often embedded in language, and closely linked with traditional conceptions of time and the seasonal round.
Consequently TPK, as it is described here, cannot be considered a discrete subset of TEKW, but is interwoven in a larger
framework of cultural knowledge and represents a broad yet significant domain of TEKW.
In temperate regions, the triggering of plant and animal development depends on the passing of certain temperature
thresholds and changes in photoperiod (Larcher 1983). In the spring most woody plant species (e.g.; shrubs and trees)
and perennial herbs (wildflowers) come into flower primarily in response to accumulated heat often measured using
growing degree summation (Rathcke and Lacey 1985). One application of phenology is to use organisms that respond
predictably to heat as indicator species. Phenological indicators can be thought of as stable biological timepieces that
respond to seasonal variation between years (Molitor 1987). Such indicators have become very important proxies to
monitor the biological impact of accelerated global warming. In Europe, researchers have used records, kept at a network
of phenological gardens, to demonstrate that the length of the growing season has increased by approximately 11 days in
the last 30 years (Menzel and Fabijan 1999). Similarly, long- term phenological data reveals a 26-day shift to the
earlier onset of spring in Western Canada (Beaubien and Freeland 2000).
Since phenological events generally occur in consistent order, with the arrival of one event predicting the imminence of
another, phenological data can also be used as a valuable predictive tool in forestry, agriculture, and fisheries
(Caprio 1966; Lieth 1974). Fishermen in Western Canada have long recognized that pickerel (Esox lucius L.) run when the
southern cottonwood (Populus balsamifera L.) releases seed, and, on the East Coast of Canada, fishermen would not fish
for shad (Alosa sapisissima Wilson) until the saskatoon, or shadbush, (Amelanchier spp.) had flowered (Beaubien 1991).
The use of plant and animal development to predict seasonal events is by no means a new practice. When Samuel de
Champlain arrived at Cape Cod in 1605, the Wampanoag people informed him that the best time to plant corn was when the
white oak (Quercus alba L.) leaf was the same size as the footprint of a red squirrel (Tamiasciurus hudsonicus Erxleben)
(Molitor 1987). On the west coast of Canada, the Nuu-Chah-Nulth peoples of Vancouver Island recognize the correspondence
between the ripening of the salmonberries (Rubus spectabilis Pursh) and the return of adult sockeye salmon (Oncorhynchus
keta Walbaum) to freshwater (Bouchard and Kennedy 1990). Phenological knowledge is also significant in the subsistence
activities of the Ka'apor peoples of the Amazon (Bal‚e 1993), Pomo and Tubatulabal Peoples in California (Kat Anderson,
pers. comm. to NT, 2002), and the Yanyuwa peoples of Northern Australia (Baker 1993).
This paper is a preliminary effort to assess TEKW that relates to seasonality and phenology in British Columbia, Canada
and surrounding regions, and to assess the significance of Traditional Phenological Knowledge (TPK) to the aboriginal
peoples in this region. Since many phenological indicators are intimately associated with language, cultural beliefs,
and traditional conceptions of time, in order to consider all possible sources of knowledge, we define TPK in a broad
sense here. TPK encompasses all knowledge of biological seasonality, including: the observation of life cycle changes in
specific plant or animal species to indicate the timing of the onset of growth stages in other species; linguistic
references to phenological events; traditional conceptions of time as they relate to seasonal change; and spiritual
beliefs about cause and effect relationships of seasonal change.
METHODS
We reviewed published and unpublished literature, noting direct and indirect references to plant and animal phenology.
Sources included ethnobotanical monographs, ethnographies, technical reports, and plant-use handbooks. In general, this
literature pertained to British Columbia, but published sources from surrounding regions (Alaska, Washington, Montana
and Alberta) were also examined . Information on TPK was grouped using a linguistic / cultural classification and is
presented and discussed by subcategories of plant [(1) berries, and (2) 'roots,' cambium, and shoots] and animal
resources [(1) fish, and (2) mammals, birds and shellfish].
RESULTS AND DISCUSSION
Plant Resources: Berries.- Indicators of the imminence of berry ripening are among the most common phenological
indicators used by aboriginal peoples in British Columbia. Phenological events used to signal the onset of berry
ripening include life cycle changes in invertebrates, vertebrates, and plants, but predominantly incorporate the
flowering or fruiting phenology of a second plant species. Indicators of berry availability include the Nlaka'pamux use
of the blooming of wild rose (Rosa spp.) as an indication that the soapberries (Shepherdia canadensis [L.] Nutt.) are
ready to harvest (Turner 1998b). One of the most interesting examples of phenological knowledge that relates to berry
ripening is indirectly encoded in the belief that the singing of the Swainson's thrush (Hylocichla ustulata Nutt.), is
responsible for ripening the salmonberries (Rubus spec- tabilis Pursh). The Tlingit, Tsimshian, Haida, Haisla, Oweekeno,
Squamish, Nuu-chah-nulth, Ditidaht, and Straits Salish all associate the singing of this bird causally with the ripening
of salmonberries. This belief is also reflected in the names for the Swainson's thrush and the song of the Swainson's
thrush in at least four languages (Haida, Oweekeno, Ditidaht, and Squamish), and encodes the direct TPK that in Coastal
British Columbia salmonberry flowers mature and the fruits begin to ripen at approximately the same time (Pojar and
MacKinnon 1994) that the Swainson's thrush returns to this part of its breeding range (Campbell et al. 1997).
The prevalence of indicators used to determine when a particular edible berry is ready to harvest underscores the
importance of these resources to the aboriginal peoples of British Columbia. Traditionally, berries were one of the most
important food resources, and served as an essential winter foodstuff (Turner 1995, 1997a; Thornton 1999). Berries were
also extremely important in trade, and as a food gift item in potlatch ceremonies (Turner 1995, 1997a; Thornton 1999).
Different berries occur in different ecosystems across the landscape, often far from where other resources are
harvested. Therefore, in addition to knowledge of berry distribution and abundance across over a given territory, a
prerequisite to such planning - this is out of context now - is precise knowledge of the temporal availability of the
berries, which would ensure that harvesting effort is not wasted. Indicator species that signaled the beginning of the
availability of a particular berry crop may have also provided human gatherers with an important competitive advantage
over other animals consuming the same resource.
Plant Resources: 'Roots' (edible underground plant parts: including rhizomes, bulbs, and swollen roots), Cambium,
Shoots, etc. In addition to berry resources, there are 16 phenological indicators of the availability of other plant
foods and materials that are documented here. These consist of: indicators of the availability of a diverse range of
resources, including: roots, bulbs and rhizomes (8), and other plant foods [cambium, shoots, mushrooms, tree sap and
seaweed] (5), and plant materials (2). Like the seasonal markers that signal the availability of berries, these
indicators mainly involve the flowering or fruiting phenology of a second plant species, but also include several animal
indicator species. Examples include: the Okanagan use of the ripening of Douglas-fir (Pseudotsuga menziesii [Mirbel.]
Franco) pollen cones to signal that ponderosa pine (Pinus ponderosa Dougl. ex Loud.) edible cambium was ready to be
harvested (Turner et al. 1980); and the Stl'atl'imx use of the blooming of wild rose (Rosa spp.) to indicate the best
time to collect cedar roots (Thuja plicata Donn.) and grass (Phalaris arundinacea L.) for basketry (Turner 1992).
For many of the aboriginal peoples of British Columbia, edible underground plant parts, which were gathered and stored
in extremely large quantities, served as an important winter resource (Turner 1995, 1997a). Like berries, the
developmental timing, and consequently the availability, of many of these 'roots' varies greatly between years. The use
of indicators as a cue for the best time to harvest would have allowed for the effective coordination of efficient
harvesting activities. Indicators of underground plant part availability appear to have been particularly important to
the aboriginal peoples of interior British Columbia, where 'root' crops were among the first plant foods harvested in
the spring, and first roots ceremonies celebrating the availability of these foods were an important socio-cultural
recognition of the arrival of spring (Bandringa 1999; Hart 1974; Turner et al. 1990).
Animal Resources: Fish.- The bulk of all of the phenological signals of animal resource availability that are detailed
here relate to the seasonal appearance of fish resources. These include 18 indicators of life cycle timing in fish, more
than half of which relate to the phenology and availability of salmon, and most of these involve the use of plant
phenology to signal the timing of a particular spawning migration. Examples include: the Nlaka'pamux use of the leafing
of desert currant (Ribes cereum Dougl.) as a sign that the steelhead trout (Oncorhynchus mykiss Walbaum) are running in
the Stein River (Turner et al. 1990); and the Nuu-chah-nulth use of red elderberry (Sambucus racemosa L.) blooming as a
sign that it is time to fish for halibut (Hippoglossus stenolepis Schmidt) (Bouchard and Kennedy 1990).
As with edible underground plant parts and berries, the high number of direct phenological indicators that relate to
fish availability highlights the importance of these resources to the aboriginal peoples of British Columbia.
Historically, these peoples consumed large quantities of animal protein throughout both the winter and summer months
(Chisholm et al. 1983). Fish were also an important item in trade and ceremony (Turner 1995, 1997a. The use of
phenological indicators would have provided an effective means of ensuring that harvesting effort was efficiently
directed. Furthermore, a mistimed harvest, in addition to reduced yields, could also potentially jeopardize the longterm
availability of the resource. For example, harvesting migrating adult salmon too early could preclude adequate
escapement for spawning.
Like the phenology and abundance of berry-producing shrubs, fish reproductive phenology, and thus availability, also
varies considerably between years. For example, the timing of the chinook (Oncorhynchus tshawytscha Walbaum) and coho
salmon (O. kisutch Walbaum) adult spawning migration into the Big Qualicum River, varied by as much as 5 weeks between
1959 and 1972 (Fraser et al. 1983). Indicators species, particularly plants that are widespread and thus easily
observable, would have provided an important cue to the availability of fish, which are inherently more difficult to
monitor than plants.
Animal Resources: Mammals, Birds and Shellfish.- In addition to indicators signaling the onset of fish abundance, there
are also a number of phenological indicators which are used to predict the availability of other animal resources. These
include: 12 indicators of vertebrate resources [deer (Odocoileus hemionus Rafinesque), bison (Bison bison L.), marmot
(Marmota spp.), harbour seals (Phoca vitulina L.), gray whales (Eschrichtius robustus Lilljeborg), and seagull eggs
(Larus spp.)], and two indicators of invertebrate resources: (horse clams (Tresus capax Gould) and butter clams
(Saxidomus giganteus Deshayes). Indicators of the timing of these resources also generally involve the use of plant
flowering phenology to signal the best time to gather or hunt. Examples of these indicators include: the Haida
utilization of the blooming of cow parsnip (Heracleum lanatum Michx.) as a sign that seagull (Larus spp.) eggs were no
longer good to harvest (Turner 1998a); and the Okanagan use of mock-orange (Philadelphus lewisii Pursh) blooming as an
indicator that the marmots (Marmota spp.) were fat and ready to be hunted (Turner et al. 1980).
Phenology in Relation to Time and the Seasonal Round.- In addition to what can be called direct indicators, where the
phenology of one species is used to signal the onset of another phenophase in a second species (typically an important
resource), there is also extensive Traditional Phenological Knowledge encoded in language and words with etymological
reference to phenological events. Most of these lexically marked seasonal indicators are inextricably linked with
traditional conceptions of time and the seasonal round. Eighty-four words in 21 languages, which make reference to a
range of phenological events and discrete time periods, are described here. Of these, 35 are related to the phenology of
plant resources, 26 of which relate to berries; and 49 are associated with animal phenology, 39 of which relate to fish.
Examples include: the Squamish name for the time period corresponding to August (temt' ka7), which is derived from the
name for salal (Gaultheria shallon Pursh) (t' ka7ay) and is glossed as 'when the salal berries ripen' (Bouchard and
Turner 1976); and the Oweekeno name for the time period corresponding to April (tcaHsAm), which is derived from the word
for eulachon (Thaleichtys pacificus Richardson) (tcaHan), and literally means 'eulachon moon' (Compton 1993).
The First Foods ceremonies of many aboriginal peoples of British Columbia, in which harvesting and food use
prescriptions were ritually enacted and the availability of a particular food was recognized and celebrated, similarly
exemplify an understanding of plant and animal development that is encoded in spiritual beliefs and ritual (Compton
1993; Johnson 1997; Thornton 1999; Turner 1995, 1997a, Turner et al. 2000). For example, the Hanaksiala of the Northwest
Coast of British Columbia celebrated the New Year (h'is‰…m hs_h'snx) when the riceroot (Fritillaria camschatcensis (L.)
Ker-Gawl) flowered (around the end of March), and performed a ceremonial flower dance in which "costumes were covered
with flowers of the Nootka rose, salmonberry, blueberries, riceroot and any other plants that were blooming then."
(Compton 1993:197).
Importance of Traditional Phenological Knowledge.- The large number of phenological indicators used by many cultural
groups, as documented in literature sources, highlights the overall importance of TPK to the Aboriginal Peoples of
British Columbia and the surrounding regions. The over 140 examples of phenological knowledge described here, even so,
undoubtedly represent only a small subset of the TPK that was used by over 20 linguistic / cultural groups. In British
Columbia and the surrounding regions TPK was used as a means to ensure that adequate plant and animal resources were
collected from across a large landscape, where annual variability in phenology would have had a considerable impact on
the availability and abundance of these organisms. In British Columbia TPK may have been particularly important because
the traditional homelands of many cultural groups are extremely heterogeneous, and plant and animal resources were
separated by great distances and or elevations. TPK proxies that allowed indigenous peoples to accurately predict when a
given resource was available without observing it directly would have increased the overall efficiency and effectiveness
of subsistence activities.
Traditional Phenological Knowledge (TPK) is an extremely important component of the Traditional Ecological Knowledge and
Wisdom (TEKW) of the aboriginal peoples of British Columbia. Phenological Knowledge in British Columbia represents a
significant domain of TEKW that shaped seasonal movements, subsistence activities, ritual, ceremony, language and
cultural beliefs. Intimately linked with traditional conceptions of time and the seasonal round, TPK was also impacted
by a much broader framework of cultural knowledge.
This type of TEKW represents another layer of the sophisticated understandings of the natural world that was required of
indigenous peoples living within their traditional territories. TPK is particularly significant because it underscores
the complexity and depth of Traditional Knowledge of the environment, which in the case of TPK integrates detailed
information from a number of 'disciplines', such as ornithology, meteorology, ecology, botany, and ichthyology and links
them together with human activities in a complex ethnoecological web.
