Palynology and palaeoenvironmental work at The Provincial Museum of Alberta
is mainly directed towards the investigation of the postglacial landscapes
and environments of Alberta, particularly
as they relate to the Province's human history, which extends back
over 10,000 years. In the last nine
years, I have worked closely with colleagues from the
Archaeological Survey on a number of joint
projects. A particular focus has been the landscapes associated
with some ancient archaeological sites, such as
Saskatoon Mountain (ca. 9500 years old), Fletcher (ca.
9300 years old), and James Pass (ca. 10,000 years old).
The Palynology Laboratory houses collections and facilities
for sample processing and analysis. The Laboratory moved recently
into new quarters in the basement of the Provincial Museum.
This now includes work space for students and visiting scholars
wishing to use the comparative collections. There are two Reference
Collections (Pollen and Seeds) for identification and confirmation
of material from lakes, peatlands, and archaeological sites.
The Pollen Reference Collection comprises about 780 samples,
mounted in silicone oil, and represents 86 plant families,
mainly from native Alberta plants. The collection has good
representation of plant taxa commonly encountered in Late
Quaternary records from Alberta.
The Seed Reference Collection is small but growing rapidly!
It consists of 220 catalogued
samples, with about 100 other samples undergoing processing,
and so far represents 47 plant families.
Because there is no published reference manual for seeds of
western Canadian plants, one recent
focus of curatorial activity has been documenting the collection
(photographs, drawings, size
measurements etc.) and compiling a database which can be used to
develop an identification manual.
Each reference sample consists of a minimum of thirty seeds,
thus allowing generation of size
statistics for comparative purposes. The collection includes
seeds from many plants known from
ethnobotanical studies to have been used by Aboriginal people in Alberta.
The Working Collections consist of samples mainly from
Alberta archaeological sites, lakes
and peatlands. At least seven records are in various
stages of processing. I am especially interested in
landscape history following deglaciation. Current
projects focus on macrofossils from 9300-year-old
sediment at the Fletcher Site in Southern Alberta
(which is now the subject of a diorama being
constructed for exhibit in the new Aboriginal Peoples
Gallery at the Provincial Museum) and analysis
of ca. 10,000-year-old plant remains from several
dugouts in southeastern Alberta (Vickers and
Beaudoin 1989, Beaudoin 1995). These remains are highly
significant because they provide a
"snapshot" view of southern Alberta landscapes at a time
that is poorly documented in the Plains
but is important for human history because it coincides
with some of the oldest known archaeological sites in the Province.
Seeds recovered from a ca. 9300-year-old hearth at
the Saskatoon Mountain Site, west of
Grande Prairie, included raspberry (Rubus sp.),
cherry (Prunus sp.), bearberry (Arctostaphylos uva-ursi),
and strawberry (Fragaria sp.). These plants were all
used by Aboriginal people in the recent past and people at
Saskatoon Mountain over 9000 years ago were presumably gathering
and using them also (Beaudoin et al., 1996). Published
Holocene pollen records are available from the area north and
west of Grande Prairie but there is comparatively little
information available from the region immediately to the south.
In consequence, three lakes (Hilltop, Pierre and Nose Lakes)
have been cored in the Grande Prairie area ) and the pollen
record from Pierre Lake is under investigation.
A recent project looked at a 9300-year-old record from
"Wood Bog", just east of Grande
Prairie. Fifty samples were processed for macrofossils
(seeds, mollusc shells, ostracodes, insects,
wood). The samples comprised over 21,000 seeds from about
forty plant types and 12,000 shells from ten different mollusc
taxa. This project provided new information about the early
Holocene landscapes inhabited by the people who occupied the
Saskatoon Mountain Site (Beaudoin 1993b). Pollen samples from
this site should provide an interesting regional contrast to
the predominantly local record given by the seeds.
Before joining the Archaeological Survey, I worked primarily
in the Canadian Rockies. I have
continued to analyse the data from this work (Beaudoin and
King 1990, 1994). As an extension of this
interest, I have recently completed an investigation,
with Mel Reasoner, of pollen focussing and
differential pollen deposition in the sediments of Lake
O'Hara (Beaudoin and Reasoner 1992).
Further afield, I have been involved in a project based
in Heilongjiang Province, northeast
China (Ives et al. 1994, Beaudoin and Reintjes 1994).
Samples from sites in southern Heilongjiang have yielded abundant
Late Pleistocene remains of large animals and tantalizing
suggestions of human activity. At Xue Tian, near the Jilin border,
for instance, remains of mammoth, woolly rhinoceros, bison, and
horse have been recovered. Organic-rich sediments from this level
are expected to produce details of Late Pleistocene environments.
