Our second plenary session provided a counterpoint to the
first, with Emma Marris, author of the Rambunctious Garden, giving arguments
for managing nature that provoked much thought for all assembled, and no doubt
for those who tuned in online.
The departure point for Ms. Marris’ perspective is that “we
can’t go back to [the] Garden of Eden, and it never really existed….The
ecosystems of North America that we see as Edenic are a product of our
management and mismanagement.” She briefly touched on arguments that landscapes
of North America were managed in pre-Colombian time, and were naturally dynamic
before the age of man, therefore there can be no valid historical reference
point for ecological preservation. The transition to modern time and the increasing rate of
anthropogenic change was not immediately apparent in the author’s description,
but perhaps was not a point that needed to be emphasized to a George Wright
audience.
If we can’t go home, to the Garden of Eden, what can we do?
The old goal was so neat, it was more beautiful back then, it was perfect back
then. In referring to “pristine-ish” nature, if we can’t “put it back,” what
goal should we use? “Picking a goal does not mean we deny the intrinsic value
of nature…. It just might be in a different place.” Different goals is how we
pragmatically manage. What is new is a psychological change, that we don’t see
interventionist management techniques such as assisted migration and use of
surrogates as last-ditch attempts. She enjoined us to be more positive and find
joy in this work. “That’s why I use the gardening metaphor. Gardening is like
stewardship,” except a steward doesn’t necessarily have to do anything, just
keep the keys and make sure nothing bad happens. “A gardener has to get down
and get dirty and intervene.”
She spoke of “novel ecosystems.” Think of them “like a weed
patch, lots of introduced species that are playing around together,” she said. “Cycling
nutrients, making soil” …functionally they look very similar to native ecosystems.
Diversity levels in some cases meet or exceed native systems.
She acknowledged that “you can’t just go nuts with this
stuff. You can’t do [just] anything. It is arrogant to say that humans can
control the earth.” We need to be humble. It is not only virtuous but smart. We
are not in control of the earth. It is not a conscious masterminding.
“The scope of our influence is massive. People start
throwing around the term Anthropocene.” More traditional conservationists
immediately see it as bad. She gave a few examples, including the Ecological
Society of America conference and people saying “cities are a cancer on the
earth,” and that from her perspective that doesn’t help.
The Anthropocene has to be acknowledged, and has caused
moral wrongs. We cannot not act. If we decide not to manage a piece of land, we
are making a decision because if we don’t act, all the other forces will act.
“I think there has been a cultural prohibition within conservation from talking
about any positive change that is anthropogenic.”
“What do we disagree on? I guess it is the metaphor of the
garden. I find the metaphor useful.” But she hopes it will hold wild things.
She emphasized that she is not talking about planting things in neat little
rows; but also argued that places like Yellowstone are already managed as a
garden, citing the example of intervention to manage the whitebark pine. “When
we go out and remove invasive species, we are already gardening.”
“You can have historical and you can have wild, but you
can’t have both at the same time.”
Many arguments of Marris, a journalist, would benefit from
more scientific underpinnings. But her central point, that climate change
and global human manipulation robs nature conservation of the no-action alternative,
is potent. She could have done more to describe the cultural dimensions of our
conservation attitudes, but her talk underscores the need to bring
multi-disciplinary science to the interventions citizens are already making.
The plenary sessions of Dr. Michael Soulé and Ms. Marris provided very different views, and both will provoke thinking and reflection on the fundamental objectives of our work in parks and protected areas. It is a great example of critical professional debate and food for thought that draws us to meetings and programs of the George Wright Society.
