An interesting article in a newspaper this morning has at last brought me up-to-date with a subject in which I took an intense, but peripheral interest while making a National Film Board film 35 years ago. namely, the fate of the bison.
Once the greatest animals in North
.America, by stature as well as by sheer numbers, with at a conservative estimate some
15,000,000 populating the plains, the bison, or buffalo, as they are now
popularly called, shrank to an infinitesimal number, almost to the point of
extinction, as a result of being ruthlessly hunted by the invading white
settlers in and around the 1880s..
Canada has a huge national park
devoted to the bison, the Wood Buffalo National Park straddling the
Alberta-Northwest Territories border. The park is so huge that Canadians have
scarcely grasped how big it is: marginally bigger, at 44,000 square kilometres,
than Switzerland, for example, or Holland, which are both 3,000 square
kilometres smaller.
The provenance of the bison
population in the park is interesting: one story goes back to the daring of an
Indian named Walking Coyote, who crossed the continental divide with four
buffalo calves that he began to raise in his native Blackwater reserve, just
over the international border in the United States. Walking Coyote was eventually
found dead under a bridge in Missoula, Montana, but meantime he had sold his
interest in the many buffalo that had
sprung from his four calves to a Mexican rancher. When Michel Pablo died, a quick-thinking representative of the Canadian government in
Great Falls, Montana managed to buy the
herd, which was transferred north by rail between 1907 and 1912. No one knew
how many animals were involved, but the number transferred was around 700.
They soon ate themselves out of
habitat in the small park set up for hem near Wainwright, Alberta, and in the
1920s a major debate took place as to whether they should be transferred into the
massive northern park, where the last of the pure wood buffalo lived . The
prairie sub-species had become impregnated by
cattle during their many years of haphazard management in Montana. The
wood buffalo sub-species is an altogether more imposing animal ---- taller,
heavier, but slimmer, and with a more noticeable fur coat over its front
quarters, a much more statuesque animal
than its prairie cousin. The scientists of the day did not want to muddy the
gene pool.
Up
to the time we were making the film the
primary interest had been in our need to preserve the distinct sub-species, the
wood buffalo. In pursuit of this aim in the 1960s, a group of 40 or so wood
buffalo that had not been fatally impregnated with the cattle genes was
transferred to a remote spot north of Great Slave Lake, where those that survived
the harrowing trip by truck, eighteen in number, were released. This small number gave rise in the next couple of decades to a herd of
more than 1000, if I remember correctly, a notable success for the animal scientists
responsible.
Up to the time I am writing about,
the 1980s, the general movement among bison-minders was in the direction of
saving their genetic makeup from being corrupted by outside influences. But
according to the article in today’s Globe
and Mail, in the intervening three or four decades the interest has changed
to an effort to re-establish even from these corrupted heirs, something, or at
least some pure-bred animals.
A number of indigenous tribes have
been collaborating in this effort with the scientists, and appear to have at
last won some success.
For their part the scientists have
been working on a method of preserving semen by freezing, something they have
now perfected and, if I understood correctly what I read (always a careful
precaution to enter), they have managed
by careful programmes of artificial insemination to produce some 40 calves that
they are convinced have reverted to the pure strain of plains bison, one whose
scientific name is now apparently bison
bison bison as distinct from the bison
bison athabascae, the scientific handle of the woods bison and of bison bison to the original strain of
plains bison.
Some Saskatchewan First Nations have
been central to this development. When
we were making our film we were interested in what was being done at Elk Island
National Park, a small park east of Edmonton, in which herds of plains and wood
bison have been kept divided, their progeny to
be later used to implant small herds in different parts of the prairies.
We filmed one such transfer, and used some archival footage to show the
fruitless effort made earlier to vaccinate the bison in the huge park to ensure their racial
purity. This effort foundered simply on
the immense size of the park: the bison wandered all over it --- imagine, a
park bigger than Switzerland and the effort needed to roundup every animal
therein. The rangers never found it
possible to round up the whole herd. I seem to remember the best they ever
managed to do was to vaccinate 4,000 out of the 12,000 estimated population at
the time. So new measures were obviously necessary.
My conclusion from having worked on
the film was that it was extremely encouraging
to find that the federal government, through its wildlife service, were
going to such lengths to preserve a magnificent animal that had been driven to
the edge of extinction by the insensate bloodlust of the early prairie settlers, who did not hesitate to
involve Indian tribesmen in their nefarious effort to wipe the animal from the
face of the earth. It is, however, clear
that he Indians had only a small part of the campaign, which was one of the
most successful animal extermination projects evr recorded: our archival
footage showed scenes that must be familiar to Canadians, of huge piles of
bison skulls, amounting to hundreds of thousands.
We discovered that the Americans had
gathered the remains of what was left to them after the transport north of the
majority of their remaining population into a smaller national park, known as
the National Bison Range, which lies in a beautiful hilly countryside, just south of the border where we were permitted to shoot. Also, we found
an invaluable photographic record of the actual 1907 transfer of the animals
to Canada, recorded on the old-fashioned glass plates kept in the University of
Montana in Missoula. So we were pleased that our film, overall, managed to give
a good sense of the history of an animal species that has played an integral
part in the history of Canada. The name of the NFB film is The Great Buffalo Saga, co-directed by myself and Michael
McKennirey.
I love these stories, ones that provide some cause for hope in these often very rocky times. And I see that your publication pace has picked up from last year, when it dropped a bit from the year before. Good show!
