Like the province, the Columbia
Basin has a rich and diverse environment, and compared to many areas
in Canada, its natural ecosystems are still relatively intact. Notwithstanding
this, there have been and continue to be, a number of human disturbances
that have irrrevocably altered the landscape. Most notable of these
are the damming of the Columbia River in several locations which
has drowned hundreds of kilometres of some of the most productive
habitat in the Columbia Basin, and clearcut logging which continues
to reduce old growth forests at a non-sustainable rate. The province
has 187 vertebrate (mammals, birds, reptiles, amphibians and freshwater
fish) species that are on the red and blue lists. The Columbia basin
has 46 species representing 24.6% of the provincial total.
In the case of vascular plants, the Columbia Basin contains 17.1%
of the provincial red and blue-listed species. Although precise
figures are lacking, a similar outlook is projected for invertebrates,
non-vascular plants and plant communities.
With recent additions to the protected
area system in the Columbia Basin, about 11.7% of the landscape
has some form of protective status. There is growing doubt however,
about the ability of these protected areas to meet long term biodiversity
objectives. Many of the protected areas contain high proportions
of alpine tundra including rock and ice, and while these areas are
aesthetically attractive, they are relatively depauperate in numbers
of species and habitats.
Many ot the protected areas identified
in recent regional land use processes were set aside at least in
part because they had no significant resource development potential.
Much of the critical valley bottom habitat was considered too valuable
for development purposes to be "locked-up" in protected
areas.
It is now commonly recognized that
many protected areas in the province are too small to contain all
the critical habitat requirements of wide-ranging species such as
Grizzly Bears.
These figures indicate that there
is considerable room for concern about our ability to preserve biodiversity
over the long term. There is an urgent need for more research and
monitoring, since many species are disappearing either without our
knowledge, or without knowledge of how to prevent the loss. There
is a need for increased legislation and regulations to prevent the
destruction of species and their habitats. There is a greater need
for cooperative arrangements between all levels of government, industry,
and private citizens alike towards biodiversity conservation. Greatest
of all is the need for a profound philosophical and attitudinal
shift away from an anthropomorphic view of the world, to one in
which all species have equal value. Failing that utopian objective,
we require a complete and compelling understanding that only in
the preservation of the ecosysytems in which we live, is our own
survival on earth possible.
