ENBRIDGE PRESENTATION
·
I have lived in Bulkley Valley since 1978
·
terrestrial ecologist; 25 years with BC Forest
Service
·
lots of fieldwork throughout nwBC, from Prince George
to Haida Gwaii, from Atlin to Bella Coola, usually in the company of earth
scientists
·
over the years have noticed that physical
scientists (soil scientists, geologists, climatologists) & engineers from
east of Rockies initially don’t “get” mountainous BC
·
often takes them several years to re-calibrate their
working reality (in terms of topography, rapid changes over short distances,
mass movements, peak flows, extreme events, really physically active landscapes
/ hydrogeomorphological processes)
·
in light of threats to terrestrial and esp
freshwater aquatic ecosystems of wc BC, from pipeline construction and
subsequent ruptures and leaks along the line:
Recommendation: review
photos of severe erosion—of roads, culverts, bridges—caused by last summer’s
rainstorms; posted on Flickr site of BC Min. of Transportation &
Infrastructure.
·
big rainstorms with surface erosion + mass
movements = a potent combination for damage to all linear infrastructure, especially
in mountainous terrain
·
Peace Region – late June 2011; along Hwy 97 from Chetwynd to
Mackenzie; more than 25 significant blowout sites; said to be a 1-in-40 year
event, but frequency will increase as climate warms
·
Coast Mtns – after 12 cm of rain from Sept 7-8, 2011; Hwy 37,
especially the spur to Stewart; massive erosion; bridges and roadbed washed
away, streams cutting new channels
·
Heckman Pass – in July 2011; bedrock failures along Hwy 20
(road to Bella Coola) after series of rainstorms
Conservation Values of West Central BC
Terrestrial—conservation values in the mountainous portions of wc BC centre on the region’s rivers—especially the larger drainages—and productive valley bottoms, with riparian ecosystems & high fish and wildlife values.
Stepping back for a broad, continental
view, the Bulkley Rges & Kitimat Rges (coastal
or coast-interior transitional mountain ecosections roughly from Zymoetz River
to Whitesail Lake)
have some nationally & globally significant ecological attributes.
· unregulated,
lake-headed salmon rivers with clean water and high quality aquatic habitat
(intact freshwater aquatic habitats one of rarest class of ecosystems in the
world)
· +/- intact
large-mammal predator-prey systems
· continentally important
habitat & populations of g bear, Kermode bear, m goat, wolf, wolverine
· coastal temperate
rainforest (aka Great Bear Rainforest)
Marine—but the really “world class” system occurs along the Coast.
·
BC’s
globally significant north & central coast, 88,000 km2 of marine
ecosystems; archipelago-fiord & continental shelf—and fractally complex land-water interface.
·
Ecosystems
like kelp forests, seagrass meadows, fertile estuaries, 9000-yr old glass
sponge reefs, seamounts.
·
Species
including whales, porpoises, rockfish, sea otters, seabirds, herring, eulachon,
nudibranchs, octopus.
·
“Combination
of complex oceanographic conditions and seafloor characteristics … with
channels, banks, deep troughs, eddies, upwellings, estuaries, and depths from 0
to 2000 m, creates a wide range of ecological niches and in turn supports a
diverse array of species.”[1]
Cumulative
Effects
Nonetheless much of the landscape along the
proposed pipeline route has been industrialised—esp across Interior Plateau.
The natural environment has been subjected to: extensive clearcut logging w
numerous roads & stream crossings; railroad + major highway; mines & effluents;
hydroelectric transmission lines; gas pipelines; agriculture.
·
All
effects are ‘cumulative’; accumulate through time and over space; do not
represent a special class of impacts.
·
Must
assess the aggregate stresses on
environmental values.
·
Series
of small +/- minor effects can accumulate to result in a significant overall
effect (death by a thousand cuts)
·
Total
impact greater than simple sum of individual stressors. E.g., access
development >> roads and stream crossings; on unstable terrain/erodible
soils >> erosion & sedimentation; >>increased hunting &
fishing pressure
Homeland
vs Hinterland
A few years ago a senior Yukon Government
manager (Energy Mines & Resources) assured me that dealing with the oil
& gas industry was straightforward because “they’re just looking for a
bigger sandbox to play in.”
A remark dismaying but revealing:
·
“manifest
destiny” approach of the industry & its servants in government
·
cavalier
attitude to natural and human environment of w Canada: tar sands, Mackenzie
Valley, Ft. Nelson Lowland, Sacred Headwaters, Bulkley Valley—each is just
another piece of bush
·
underlying
assumption that collateral damage from O&G exploration, development, &
transport will be insignificant because it occurs in a sparsely populated
hinterland
·
distinction
between homeland & hinterland that Thomas Berger highlighted in Mackenzie
Valley pipeline hearings.
Conclusion
Because of threats to the natural
environment of west central BC—in particular to the freshwater aquatic and
marine systems—from pipeline construction and subsequent ruptures and
leaks along the line, and from oil spills and other pollution from tankers
along the coast;
Because of the
unacceptable attitude of the oil & gas industry and senior governments toward
the people who live along the proposed route;
And because of the
threats to our homeland, our quality of life, and the stability and health of our
communities;
I am strongly opposed
to this proposed pipeline.
