New
Zealand
provides a manageable case study of the process of
ecological
transformation--the creation of a neo-Europe
historians don't just make generalizations, they look at how
the story
unfolds in a particular time and place
how do you decide any given example is typical? or do you
want to use
an extreme example because it highlights the issues
It was particularly unique because of its extreme isolation
- 89% of
native plants are endemic (exist nowhere else in the
world)
- many familiar
kinds of animals were
missing and other animals had taken those niches
- before the
aborigines
(Maori) arrived there were no land mammals but
the bat (therefore birds took many of the ecological
niches usually
taken by mammals--for example, the only large grazing
animals were
birds)
- also the culture of
the
people was unusual
one way to think about an ecosystem is as a series of
niches--ecological opportunities
what fills these niches if the usual animals aren't there?
giant
weta
an insect that takes the ecological niche of a mouse--
unfortunately cats think them great entertainment
Another animal filling the
niche
of the mouse was the Stephens Island Wren
A
flightless
songbird--one of only three flightless songbirds ever known
and the world's smallest
- Lived on a one
square mile
island off the northern tip of the South Island--a
remnant of the
ecosystem as it had been before the Maori brought with
them rats
- "It was only seen
live on
two occasions when it was disturbed from holes in rocks.
It was thought
to have been semi nocturnal and ran very fast like a
mouse." (source)
- At the
Ornithologists Club
in London in 1894 a collector proudly displayed 10
specimens of the
wren that had been killed by the lighthouse keeper's cat
- He also announced
that the
species was now extinct due to the cat
the largest flightless birds, the
moas, filled the niche of grazing
animals
All 11 species of Moa were hunted to extinction by the Maori
in the
13th and 14th century. They only laid one or two eggs
at a time
and took 10 years to grow to maturity so were wiped out
easily.
"Second only in weight to
the
extinct elephant bird of Madagascar, the largest moa was the
tallest
bird on earth, with the top of its' back 6 feet above the
ground" (source)
The largest Moa still weighed over 500 lbs. They ate
mostly
bushes and the lower branches of trees. Their beaks
were strong,
able
The Haast's eagle, with wingspan of 3 meters, preyed on the
Moa and
died out with it
The environment needed to be transformed to make it
appealing to
European settlers
- the climate was
suitable
- they set out to
change the
ecosystem
- the Maori took up
growing
potatoes, giving them something to trade with
Europeans
- pigs went wild
quickly and
the population grew
- some weeds (white
clover)
couldn't spread without insect pollination--bees were
brought in 1839
- you couldn't have a
lot of
grazing animals until European grasses spread
compare
to other natives the Europeans met:
- some more organized
societies almost immediately saw the Europeans as a
threat
- some people weren't
very
interested in what the Europeans brought
- the Maori were
different--not technologically sophisticated but well
organized and
open to new ideas, had a culture based on warfare
Maori adopted European ways with
enthusiasm
(more Maori
history)
- the Maori grew cash
crops
and raised pigs to sell the the Europeans
- they wanted iron
tools and
axes and
muskets for
inter-tribal warfare
- Europeans sold them
large
numbers of guns
- they weakened
themselves by
fighting among themselves
- missionaries
introduced the
plow in 1820
- they learned quickly
from
the Europeans, even building mills to grind the grain
they had stated
to grow
Maori were very vulnerable
to
disease:
- few bacteria that
affect
humans had made it to New Zealand
- their culture didn't
know
how to cope with disease
- diseases like
smallpox and
measles got there slowly because it was such a long ship
journey the
disease didn't get there at first
- their culture made
them
vulnerable to venereal disease--practices of sexual
hospitality
- venereal diseases
reduce
the birth rate
then the Europeans started
to
settle
- In the early 1800s
the
Maori
embraced Christianity and literacy
- (European technology
was
equivalent to magic so must have something to do with
religion)
- Maori attempts to
copy the
Europeans and meet them as equals didn't stop the
Europeans from
stealing their land
- they ignored the
claims
of the native people or
took advantage of different understandings of land
ownership
- "Traditional Māori society did not have a concept
of
absolute ownership of land. Whānau
(extended families) and hapū
(sub-tribes) could have different rights to the same
piece of land. One
group may have the right to catch birds in a clump of
trees, another to
fish in the water nearby, and yet another to grow crops
on the
surrounding land. Exclusive boundaries were rare, and
rights were
constantly being renegotiated." (source)
- the 1862
Native
Land
Act sought to assign individual ownership to Maori
land
so it could be readily traded
- side note:
- our modern
American
system of land ownership is quite unusual
- if you own land
you can
do anything you want with it
- in other places
you often
had only partial rights to land (even today)
- many limits on
what you
can do with your land
- Maori tried to meet
the
Europeans as equals and were cheated
- eventually in the
1850s the
Maori resorted to war, and were smart enough to work
together
- but already they
were
already
outnumbered by settlers and couldn't sustain the fight
- by 1870 only 1/5 the
population were Maori
Europeans
took control of the land by force
- Europeans had
developed the
expectation that they could replace the native
people
- in North and
Central
America disease was the largest factor
- sometimes
ecology played as
large a role
- they succeeded
where they
had an ecological advantage, as in New Zealand
- they changed the
ecosystem
from the native one to a European one
- in South Africa
Europeans
had a bigger cultural advantage, but they failed
because they didn't
have an ecological advantage
- warfare, disease
and
changing the ecology were parts of how the Europeans
succeeded almost
everywhere, but the balance varied from place to
place
How does this case
study support
Crosby's arguments?
- Europeans had
biological
advantages that allowed them to take over
- Why?
- they were
already resistant
to the diseases they brought with them
- the places
they went to
had few diseases because of isolation
- Europe had
many diseases
because they spread over a large land mass, dense
population, and many
domestic animals
- sheer
numbers--Europeans
settled and compromised with the indigenous people
until their increase
and the the decrease in the native population caused
by diseases gave
them the advantage
- changed the
ecosystem to
one that suited them
- Europeans
wouldn't want
to settle unless they could have familiar plants
and animals
- they would
have had a
harder time feeding themselves if they had been
dependent on native
plants and animals
- the spread of
European
plants and animals may have put the Maori at a
disadvantage
- as well as
biological
advantages, Europeans
had technological advantages--particularly over
cultures like the Maori
that didn't have metal. Also Europeans had a
government and
economic system suited for taking control of other
people's land
