ver the years Larry Stevens has contributed many articles to the
BQR discussing a variety of subjects. Not all of them have met with
universal acceptancein fact, a few have drawn heavy fire. In the
following pages we present two viewpoints that came in response
to pieces by Larry discussing the role of science in Grand Canyon,
and the downstream ramifications of draining Lake Powell. A clarification
from Larry Stevens follows. Christa
esearch
of any kind can be a benefit. Endangered species come to mind. I
used to help a friend, Chuck Minkley, with fish research on the
Little Colorado River in the early ı80s. He was the best of the
first of the Humpback Chub researchers and his teams acquired a
lot of the currently used information. Those thirty-day Minkley
projects were all done without benefit of a river trip. Everyone
hiked in and out. And so that project felt pretty good to me. These
days, a single unsuspecting chub could get shocked, snagged, tagged,
and otherwise violated four times in a single day by four different
research groups. I wonder what they do with those Willow Flycatchers.
Whether you are pro-dam or not, the sword of research is double-edged.
Sometimes it is useful, sometimes mischievous. I tend to think of
it as a sort of intellectual war, with research being the mercenary
for either side. For the research project, it is often not a matter
of doing right or wrong for Grand Canyon. Itıs a matter of who is
buying the groceries and what do they want done. The two sides line
up against each other and hire the best, most prestigious research
personnel they can get in order to sway opinion in their favor.
Unfortunately, the entities lined up against positive change seem
to have infinite capital.
Do you suppose wapa cares about split-twig anything? Or how about
the Los Angeles Water Boardthey wonıt be hosting their company
picnic at Toroweap Iıll bet. Itıs just politics: petty, grinding
politics at its most absurd. Organizations like these are masters
at relentless research-project delay tactics. Itıs a cheap way to
buy time. And all the while the river corridor loses a little more.
If we are going to hire the government to do research aimed at derailing
change, why not be fair about it and also hire them to fully explore
the viability of dam de-commission? At the very least, as taxpayers,
we should seek to eliminate the kind of waste and unfairness we
are seeing with politically motivated research projects. No matter
what is studied, proposed, or actually done to mitigate damage from
the dam, the irrefutable fact is that the deterioration of Grand
Canyon will continue so long as the dam remains. In many ways I
have said this all before, with photography, writing, and talking.
And I will keep on saying it until the lake is gone. That elegant
ocean of concrete below the Carl Hayden Visitor Center is the great
destroyer. It was a bastard child born of greed and avarice and
has no rightful place in a world society. It is a vulgar misfit
and should be put out of its misery. Let appropriate research lead
the way.

Stevensı A Butt Pygmyıs Rebuttal (bqr Fall 1997) conjured up an
old TV commercial: Remember the one where a robed and crowned woman
portraying Mother Nature is handed a muffin slathered with Brand
X margarine? It tastes so good, she thinks itıs butter. After being
informed of the deception, she sternly proclaims: ³Itıs not nice
to fool Mother Nature,² as thunder rolls at the sweep of her arm.
To be credible, a scientist in the (battle) field
of biology must first be able to distinguish between natural ecosystems
and manufactured ones. This should actually be easier than telling
butter from margarine. But in attempting to bestow divinity upon
concrete, Stevens fails this simplest of tests. What he alludes
to as ³environmental gains² from Glen Canyon Dam are in reality
limited, short-term social benefits.
Although I am personally repulsed by the crass categorizations
of science, as an advocate for wildlands and ecosystems I rely largely
on science to support my cause. I have come to respect it, and to
embrace the adage that science is a journey to truth. The masquerade
of economics and/or ³human benefit² as biological science confuses
biology with socio-economics. Promoters of contrivances and manipulations
based on bias are not scientists. But the root problem is billing
as ³science² the twelve ³gains² that the dam and other ecological
manipulation of the river ecosystem have ³created.² Indeed, these
are technically scientific observations,
but they tell us nothing of what the Grand Canyonıs river ecosystem
is truly like, and what it needs to survive. These are purely socioeconomic
judgments, not scientific hypotheses.
Stevens concedes that this soul-less constipatory
plug destroyed Glen Canyon, but the nature of his lament over this
loss reveals the philosophical motivation behind his pseudo-science:
the fact that an incredible ecosystem was drowned isnıt the concern.
That we lost what ³should have been one of the worldıs great scenic
parks,² is. Biological science should represent our best definition
of ecological reality, not a manipulated recipe wherein naturalness
and perceived ³improvements² that humanity has judgmentally imposed
upon the Earth can be mixed to produce a desired product. In some
places human manipulation can and should be a part of the landscape.
But letıs be frank about what was made ³better² and for whom, especially
in Grand Canyon.
Moreover, the 35 years that Glen Canyon Dam has bottled
the Colorado River does not even represent the drawing of a single
breath in the context of this riverıs long life. To pass the dam
off as a static reality that cannot or should not be reversed is
to regard as sacred the works of humanity, subjugating the natural
world and justifying its manipulation. The proposal to remove Glen
Canyon Dam is far more reasonable than was the proposal to build
it, whether using a social, economic, or ecological measuring stick.
To present the alleged and narrowly defined human ³benefits² of
Glen Canyon Dam as a mitigating component of the damıs ecological
consequences is like saying itıs okay that we broke someoneıs leg
because the designer cast we fitted them with is attractive. Stevens
sees the Grand Canyon as an impressive chasm to which we can apply
window dressing and cute accouterments to ³correct² its worldly
imperfections as if it were a polyester Christmas tree begging for
ornaments. He judgmentally refers to the pre-dam Colorado River
as ³sterile,² (this is a desert, not a rainforest) while raving
about the damıs creation of a ³more productive river.² And just
what is more productive? The ³trophy² trout fishery, and ³more²
of everything from vegetation to birds. Is this how ³science² measures
ecological integrity? Let us hope that the biological architects
and purveyors of the theme park mentality have a small following.
Let us hope that their rebuilding of Grand Canyon is not upon us,
wherein we can expect proposals from masons to build the walls higher,
and zoo keepers to introduce hippopotamus. The latter proposal would
be little more of a ³benefit² justifiable by biological science
than any other introduced, exotic species. It would be no less a
Frankensteinean manipulation, nor a de facto defining of the Canyonıs
ecological purpose as an amusement park. It is the incumbent responsibility
of a biological scientist to understand that ecosystems are dynamic,
and what we judgmentally perceive as ³flaws² are integral, necessary
components. It is further critical for humans to approach the natural
world with the understanding that perfection embodies what we might
perceive as imperfection. Not only is it not nice to fool Mother
Nature, it isnıt possible. Butter might not be the perfect food,
but itıs real. And weıll all be a lot better off in the long run
if we let it be butter. But to let the Grand Canyon be the Grand
Canyon will take more than the patience of the ages, it will require
humility.

Science, Values, and Vision for the Colorado River
wish we lived in a world where big problems could be solved with
simple solutions. Iıve tried to explain, obviously unsuccessfully
to some, that decisions as large as the construction of Glen Canyon
Dam involve irreversible trade-offs. Regrettably, the dam eliminated
Glen Canyon, and transformed the flood-prone, sediment-laden, and
seasonally warm Colorado River in Grand Canyon into a regulated
river, one with far greater native biodiversity and biological productivity
than existed there in the pre-dam past. Although several vertebrate
species (especially fish) have been extirpated, the river corridor
has become a refuge for numerous aquatic and terrestrial species,
some of which are federally endangered, and most of which deserve
more protection than they get. There is little doubt about these
ecological changes, as they have been the focus of intensive scientific
study by a wide array of scientists for the past two decades. In
addition, there have been widespread introductions of non-native
fish, fish parasites and plant species, and a considerable percentage
of the Upper Basinıs flow has been abstracted through trans-basin
diversion projects. These irreversible changes mean to me that removal
of the Glen Canyon Dam will not restore the Colorado River in Grand
Canyon to its pristine (pre-1880) condition.
This is not a justification for past actions, nor an endorsement
of present-day poor judgment; rather, it is a wake-up call for increased
participation in the now extremely public process of river management,
and a call for improved long-range planning and implementation of
appropriate actions. But how and what? Speaking as an ox and a moron,
I recognize an oxymoron when I see one, and ³ecosystem management²
is clearly one such conundrum. Ecosystems are too complicated for
humans to understand, much less manage. Sure we can grapple with
issues of water and sand in Grand Canyon, but the living world is
just too humblingly intricate a web of interactions to direct through
human design, for some weird set of changing values. And you know
that we will be hated by future generations for what we have done
to the Earth. But because we are responsible for these ecological
changes, we must try to do the best job of stewardship possible
for the future, recognizing our limitations and the large potential
for errors in judgment. This is the spirit of adaptive management,
recognizing that we canıt know enough about ecosystems to manage
wisely, but are intelligent enough to plan on continued learning
through the scientific method, and working cooperatively towards
the best possible future for the earth and humanity.
Management of the Colorado River suffers strongly from strabismus:
one eye is focused on ecological integrity while the other is trained
on economic exploitation. Therefore, since the 1996 Record of Decision,
the solution has been to manage democratically by committee. Gcrg
holds a chair on the Adaptive Management Work Group (amwg) and its
information support team, the Technical Work Group (twg). Gcrg is
one of several
³potentially environmental² voices among the 27-member amwg, which
is a Federal Advisory Committee. The amwg advises the Secretary
of the Interior on how to manage Glen Canyon Dam, based on the legislation
of the 1992 Grand Canyon Protection Act, the 199596 Environmental
Impact Statement and Record of Decision, the ³Law of the River,²
and the status of ecosystem resources. Like the previous Glen Canyon
Environmental Studies Program but with more reliance on a competitive,
peer-reviewed approach, the Grand Canyon Monitoring and Research
Center coordinates scientific monitoring of Colorado River ecosystem
resources, providing that information to all stakeholders. ³Potentially
environmental² voices comprise more than half of the amwg, but although
virtually all meetings are open to the public, few members of the
public attend or even write letters to the chairs of these committees.
Is the committee approach working well? Ask your gcrg representative.
As far as science being used as a delay tactic to maintain the
status quo, I think it is important to distinguish between scientific
progress and management process. I certainly acknowledge that it
has taken several decades to gain predictive power in understanding
the interactions between flow and sediment downstream from Glen
Canyon Dam. But we are not yet close to understanding most of the
biological complexities in Grand Canyon, except perhaps for trout
in the Glen Canyon reach. More research and monitoring, and a more
rigorous discussion of values, are required to arrive at the point
where we can be comfortable that we know how to manage the riverıs
aquatic and terrestrial ecosystems adequately.
At its heart, the river corridor in Grand Canyon is extraordinarily
altered. As an ecologist concerned with conservation biology, I
fully appreciate the importance of Wilderness designation as a long-term
landscape protection strategy in Grand Canyon. That designation
should apply to ecosystems (such as the Canyonıs tributaries, deserts
and the rim ecosystems) that are still primarily affected by natural
forces and largely pristine. But the Colorado River ecosystem has
been inalterably transformed by human actions. This does not mean
the river is not worthy of reverence, protection and a commitment
to hard work for appropriate management. But perhaps additional
special legislation is required for suitable protection of this
odd couplet of wilderness and modified river ecosystem in Grand
Canyon National Park. Iıve had the phenomenal privilege of spending
more than 3,000 days in Grand Canyon over the past three decades,
as a river and trail guide, a park ranger, and a scientist. Each
day there has been an inspiration. I do not pretend to know it because
itıs so much larger than human awareness. Also, I canıt pretend
to know how other people see it. My experience and bent is quite
different from most peopleıs, and I recognize that my values are
not necessarily common values. But the assignment of valuesnot
just agency policy, but the publicıs actual vision of this river
of the futurerequires additional, rigorous debate. The consensus
achieved needs to stand for a long time, perhaps the Twenty-first
Century, certainly for a much longer period than the normal three
to five year planning horizon. In some ways the critical editorials
about my vision indicate that there is enough energy among us to
support such a debate.
I do worry every day as to what is best for the river and the Canyon.
As a scientist, I continually grapple with my own biases and ignorance
in understanding the nature of nature in a human-dominated ecosystem.
I try to communicate what I learn to others, particularly to my
peers in the scientific community, to river guides and to other
interpreters who reach the public directly, and to managers who
have to decide how to proceed with their impossible task. Some of
the information is non-intuitive, and some of it is controversial.
The largest lessons, those about perception and assumption, are
inevitably humbling: the Grand Canyon wears many veils, and has
many tricks up her many sleeves. I donıt know any other solution
to overcoming oneıs personal limitations than to keep trying to
see clearly. My New Yearıs wish is that we all use the Canyonıs
foremost gift - inspirationto rededicate our lives to working for
the best future of our fellow humans and the biological integrity
of our planet.
