	title = {How can we find evidence of people in postglacial palaeoenvironmental records from Alberta?},
	year = {1998},
	address = {Victoria},
	abstract = {There are well over 100 palaeoenvironmental records from Alberta, spanning the range of the postglacial. Yet, of all the factors that are used to account for vegetation changes in these records, human agency is rarely invoked. Underlying much of the analysis is an implicit assumption that the contemporary landscape is {\textquoteright}natural{\textquoteright} and the product of natural processes. Consciously or not, people are considered to be outside these natural processes. Human agency is only used as an explanation for vegetation changes in the Late Holocene, following EuroCanadian settlement. Perhaps this mirrors another implicit assumption, that only settlement and agriculture, with concomitant land clearance, can leave a signal in the vegetation record. Records will need to be sampled at much higher resolution than hitherto to detect the more subtle changes in vegetation likely to arise from the activity of hunter-gatherers. Fire history appears one of the most promising lines of investigation. Indeed there is considerable urgency in disentangling anthropogenic and climatic signals in the fire records from the perspective of land-managers concerned with reinstating {\textquoteright}natural{\textquoteright} fire regimes in areas such as National Parks. There has also been remarkably little palaeoethnobotanical research in Alberta, although work at Saskatoon Mountain shows that there is great potential in favourable preservation locales. Perhaps this arises from palaeoethnobotanists{\textquoteright} concentration on cultigens, which are unlikely to be present in Alberta. The challenge for both these disciplines will be to devise criteria for the recognition of plant use and vegetation modification by people where exotics are not present as an indicator of human presence.},

	title = {Macroremains from the Fletcher Site (DjOw-1), Southern Alberta, and Implications for Early Postglacial Landscapes on the Canadian Plains},
	year = {1998},
	address = {Victoria},
	abstract = {Fine fraction analysis of matrix samples from Cody-complex levels of the Fletcher site (DjOw-1) has yielded abundant macroremains including seeds, plant fragments, mollusc shells, bird{\textquoteright}s egg-shell, insects, ostracodes, and faunal remains, dated around 9,300 yr. BP. Identified seeds include those from aquatic (Potamogeton, Zannichellia palustris) and wetland (Scirpus) taxa that suggest the presence of permanent, if somewhat brackish, water. At present, the area has few sources of permanent water on upland surfaces, especially in mid-summer. Other identified macroremains include Scirpus validus/autus, Ranunculus sceleratus, Ceratophyllum demersum, Hippuris vulgaris, Boraginaceae, Chenopodium spp., Graminae, Polygonum, Cyperaceae undiff., Typha latifolia seeds, and Rumex periaths. Molluscs include the aquatic taxa: Gyrsaulus spp., Promenetus exacuous, Armiger crista, Lymnaeidae, Physa, Pisidium, and Helisoma. The assemblage also includes a few specimens from land snails (Vallonia, Succinea, and Vertigo). Above the Cody-complex levels, there is a transition to clastic (windblown?) sediment which is essentially sterile. This sediment infilled the wetland hollow. The Fletcher site record is one of a series of new palaeoenvironmental records that also includes the Jenner and Weber Dugouts (constructed for cattle watering) in Southeastern Alberta. These sites have yielded wood, including aspen, dated between 10,150 and 9,800 yr. BP. Together, these three records are providing a more complete picture of early postglacial landscapes (ca. 11,000-9,000 yr. BP) in southern Alberta and indicate considerable differences from present landscapes. In particular, they suggest that early postglacial landscapes were well-watered, despite indications of climatic aridity from elsewhere. Water may have been derived from melting residual ice and permafrost contributions to groundwater. The Fletcher site shows that there may have been more (fresher) water sources on the Canadian Plains in the early postglacial than at any time since. Perennial water and productive wetlands may have been attractive for human occupants, especially in summer. This suggests that Paleoindian occupation patterns and land-use on the Canadian Plains may be quite different to those of later occupants.},

	title = {The Landscape Context for Early Postglacial Paleoindian Occupation on the Northern Plains},
	year = {1998},
	address = {Victoria},
	abstract = {Recently, palaeoenvironmental records, including new plant macrofossil evidence, from the Northern Plains (Alberta and Saskatchewan) have yielded information on the early postglacial landscapes (ca. 11,000-9,000 yr. BP) occupied by Paleoindians. Although coverage is patchy, the records suggest general patterns of vegetation and landscape development that provide the basis for a testable model. Specifically: 1) a recently-completed plant macrofossil record from the Andrews site, southern Saskatchewan, contains white spruce cones and needles at a level radiocarbon-dated from sprucewood to 10,200 yr. BP, 2) in Southeastern Alberta, the Jenner and Webb sites have yielded wood, including aspen, dated between 10,150 and 9,800 yr. BP, 3) in south central Alberta, the Fletcher site (DjOw-1), has produced seeds from wetland and aquatic plants dated around 9,300 yr. BP. Already-published pollen records from northern Montana show predominantly open, probably arid, landscapes between 12,000-10,000 yr. BP. Based on these observations, we propose the following scenario for a transect moving away from the Laurentide ice margin, extending from southern Saskatchewan, through southern Alberta to northern Montana, around 11,000-9,000 yr. BP: a) abundant residual ice and proglacial lakes, b) a belt of open spruce forest in newly deglaciated terrain beyond the ice margin, c) hummocky terrain with abundant kettles and melting ice,supporting perennial wetlands, surrounded by aspen, d) perennial wetlands probably surrounded by open grasslands, perhaps with some aspen in particularly sheltered or moist locations, e) grassland changing to open parkland terrain in the foothills. This transect roughly follows a trend of moisture-availability. Around 10,000-9,000 yr. BP, several records show a transition to clastic (windblown?) sediment that infilled wetland hollows. By this time, any residual buried ice and permafrost had melted. Further drying and sediment redistribution occurred during the Hypsithermal. Subsequent moisture increases, associated with cooler Late Holocene conditions were insufficient to produce permanent water bodies in these locales. This model suggests that there may have been more water sources on the Plains in the early Holocene than at any time since. Despite indications of climatic aridity, the Plains landscapes were probably well watered. Perennial water may have made these productive areas and attractive for human occupants, especially in summer. This model has implications for Paleoindian lifeways and occupation patterns in the Northern Plains.},

	title = {Of Mud and Men: History of the Fletcher Site (DjOw-1), Southern Alberta},
	year = {2001},
	address = {Banff},
	abstract = {Situated in the most arid region of the Canadian prairies, water has always played an important role at the Fletcher Site (DjOw-1). Water, the digging of a dugout, was involved in the site{\textquoteright}s recognition, and water, in the form of a lake and its associated resources, probably attracted Paleoindians to the locale around 9000 years ago. Indeed, waterlogged conditions at depth have preserved a fine record of plant and other macroremains from the early Holocene. The record supports a view of early Holocene water availability on the plains that forms a strong contrast with today. Since Forbis and his team worked there almost forty years ago, Fletcher has remained one of the most important Paleoindian sites in western Canada and it continues to contribute to our understanding of human occupation on the prairies.},
